When it comes to monitoring network performance, knowing how to stop packet loss of all kinds—internet, Wi-Fi, or ping—is crucial. In this post, you’ll learn the ins and outs of high packet loss and how to handle it within your system.

I’ve also compiled a list of five of the most effective software programs for eliminating packet loss. While any one of these solutions can help get the job done, I’ll discuss why I personally recommend Network Performance Monitor or VoIP & Network Quality Manager from SolarWinds, and the important reasons why you’d use one solution over the other.

What Is Packet Loss?

Before we get into packet loss, let’s unpack what packets are. Packets, or network packets, are small units of data carried over a network. Everything you do on the internet, from sending emails to downloading gifs, is made up of packets. Packets are sent to their destinations along the most sensible path to maintain network efficiency. By doing this, the network can more evenly distribute its load across many pieces of equipment, which enhances performance.

What does packet loss mean? Oftentimes, packets don’t successfully make it through the network to their destination. Internet packet loss, sometimes called latency, occurs when packets get lost in transit during their voyage. Wi-Fi packet loss is likely to occur in private, wireless networks because when things are sent through the air, it’s easy for them to get lost or dropped. This becomes even more likely on long-distance internet connections because the packets have farther to go and, by extension, more room for error.

Unsuccessful packets slow down network speeds, cause bottlenecks, and throw off your network throughput and bandwidth. Packet loss can also be expensive. If you don’t do all you can to cut down on packet loss in your system, you’ll have to spend a lot of money on extra IT infrastructure and more bandwidth to accommodate the lag.

What Causes Packet Loss?

There are many causes of packet loss, most of them unintentional. The number one cause of packet loss is network congestion.

1. Network Congestion

Think of packets traveling across your network like cars going down a highway. At certain points in the day, like during rush hour or after lunch when all the employees in a large company are going back to their desks, there are too many cars on the road. Things get even worse when a four-lane highway narrows into a two-lane road, and a lot of cars are looking to merge at the exact same time. Inevitably some cars can’t merge and don’t reach their destinations on time.

Highway traffic is a fact of life and so is packet loss. Networks aren‘t indestructible or infallible, and they have space limitations.

When network traffic hits maximum capacity, packets will have to wait to be delivered. Unfortunately, packets are the first things to get left behind when a network is trying to catch up with traffic and the connection can only handle so much. Luckily, most software today will circle back for those discarded packets by automatically resending the data or slowing down transfer speeds to give each packet a chance to make it through.

2. Problems With Network Hardware

Glitchy, old, or otherwise outdated hardware can significantly weaken your network. Firewalls, routers, and network switches all take up a considerable amount of power. If your company grows but your hardware capabilities don’t expand with it, you could be in for packet loss or even total connectivity loss.

3. Software Bugs

Unchecked bugs in your system can disrupt network performance and prevent it from sufficiently carrying packets. Sometimes rebooting your hardware will solve this, but since bugs are often introduced during hardware updates, the whole thing will need to be patched.

4. Overloaded Devices

Simply put, this means your system is running at a higher capacity than it was designed to handle. In fact, packets on overutilized devices sometimes make it to their destinations, but by then the network is too weak to process the packets and send them back out. Many devices have buffers in place to put packets in holding patterns until they can be sent out. However, these buffers can get filled up quickly and excess packets are still dropped.

5. Security Threats

We also cannot ignore the possibility of someone deliberately tampering with your network and causing packet loss. Packet drop attacks have become popular with cybercriminals in recent years. Essentially, a hacker gets into your router and tells it to drop packets. If you notice a sudden drop in packet success or a significant slowdown in network speed, you could be in the midst of an attack.

There’s also something called a denial-of-service attack (DoS) where legitimate users cannot access their emails, files, or online accounts because of a cybersecurity threat. Hackers execute a denial-of-service attack by flooding the network with too much traffic for the network to handle, and it crashes. The attackers then take advantage of this vulnerability. If your system is already under attack, there’s not much you can do for packet loss, but if you act quickly enough, you can use an access list (ACL) to block the IP address of the hacker.

When it comes to network maintenance and cybersecurity efforts, I think it’s best to internalize Murphy’s Law—“anything that can go wrong will go wrong.” I like to tack on “so you should be prepared” to the end. Invest in a SIEM solution, create a disaster recovery plan, update your firewall and, as always, keep yourself up to date on the latest antivirus software.

Such attacks are rare—there are more common causes out there for packet issues. If you’re experiencing packet loss, it’s probably just your network.

6. Inadequate Infrastructure for Handling Packet Loss

Sometimes packet loss isn’t entirely the network’s fault. Many IT administrators cobble together a networking monitoring system out of different tools. Since most of the tools have limited functionality because they were engineered for a specific purpose, the network isn’t fully protected. Without a comprehensive, seamless network monitoring solution, opportunities to stop or prevent packet loss fall through the cracks.

How to Reduce Packet Loss

Wondering how to reduce packet loss? Before we get into options for a packet loss fix, it’s worth it to say there’s no way to completely stop packet loss. Zero percent packet loss is unachievable because the things causing it, like network issues, too many users, or an overloaded system, are bound to pop up. Any solutions recommended here or elsewhere are ways to help fix the problem after the fact, not prevent them from occurring.

But there are some tried-and-true methods you can try on your own to fix high packet loss.

  1. Check your connections: First, get rid of the obvious options. Make sure your cables and ports are plugged incorrectly.
  2. Restart your system: If you haven’t turned off your system routers or hardware in a while, now is the time. This might give your network the jumpstart it needs to fix any tiny glitches or bugs.
  3. Try cable connections instead of Wi-Fi: Since everything is connected by Wi-Fi nowadays, packets are more likely to get lost. Using an Ethernet connection instead of Wi-Fi can help move things along. A fiber-optic connection is even better.
  4. Remove anything capable of causing static: Cut off surrounding cameras, devices using Bluetooth, wireless speakers, and headphones. You also might want to temporarily shut down your firewall since it uses a lot of bandwidth, and you shouldn’t be running more than one firewall program at a time.
  5. Update your software: It’s time to stop putting off your software updates. An up-to-date operating system is less likely to have bugs, which inevitably leads to fewer opportunities for packet loss.
  6. Replace out-of-date hardware: The same concept applies to your network infrastructure. Take some time to make sure your hardware is in good shape.
  7. Use QoS settings: Quality of Service (QoS) settings help you manage packet loss by triaging your network resources accordingly. This is especially important if your network transmits resource-intensive data like streamed content, online games, video calls, or VoIP. QoS settings will devote more network traffic to the places that need it.

Best Tools to Reduce Packet Loss

Five top products to minimize packet loss

Software can’t totally fix high packet loss. The key to preventing or lessening the impact of packet loss is network visibility. A problem you can see is a problem you can solve. The tools listed below, in addition to boasting features specific to packet loss, can be used to give you a more comprehensive view of your network. The most important steps for handling packet loss are pinpointing exactly what’s causing the latency and then doing your best to maintain a healthy network. Both tasks are accomplished with networking monitoring best practices.

1. Network Performance Monitor

SolarWinds Network Performance Monitor (NPM) is one of the best all-inclusive, comprehensive network monitoring tools you can buy. It’s at the top of so many of my lists because its approach to network visibility is unmatched. A whole array of network visualization tools, including intelligent Orion® Maps, geographic maps, and SolarWinds Network Atlas, give you useful, in-depth ways to see what’s going on in your network.

Network Performance Monitor (NPM)

NPM is an excellent choice for admins who have to keep watch over a large systems environment—the hop-by-hop packet path maps are especially useful, as you can quickly see if the problem lies inside or outside the network, and the tool provides the info you need to start addressing the issue quickly. This software is great for the highly specific troubleshooting required when you’re wondering how to get rid of packet loss.

Its proprietary NetPath network path analysis feature will be able to tell you where an application or the network itself is responsible for your packet loss. This function highlights the problem links in red, making troubleshooting easy. Also, NetPath displays each router and switch in the network route as a node. If you hover over the node, it pulls up the latency and packet loss statistics.

Along the same lines, the LUCID (logical, usable, customizable, interactive, drill-down) user interface in NPM gives you a complete summary of all network activity, device status, and alerts, so you can see how your system is doing without having to toggle between different screens. Bonus: NPM is fully customizable. Being able to see everything is great, but at the same time, nobody wants to be bombarded with that much information all the time. It’s easy to play around with the configurations in NPM so you only see what you want when you want to see it.

The auto-discovery function in Network Performance Monitor also deserves a special mention. After you set it up for the first time, it recurs automatically, so any changes made to the network will show up in the tool. It also compiles a list of all the network devices in your environment and creates a network map. Finally, NPM offers SNMP monitoring features and picks up SNMP warning messages, so you can see which routers and network switches are nearing capacity. Now you can combat packet loss before it even happens.

2. VoIP & Network Quality Manager

SolarWinds VoIP & Network Quality Manager (VNQM) is specially designed to focus on the network conditions necessary for successful VoIP delivery. By pulling call data from Cisco Unified Communications Manager and Avaya Aura Communication Manager, you can easily identify what’s causing latency, jitter, and call noise.

VNQM

Voice over IP (VoIP) is tricky for IT departments to negotiate because it’s hard to deliver reliable, quality telephone service using a network with a bunch of applications already competing for bandwidth. QoS settings can help by diverting bandwidth to the applications that need it most, which helps, but you need a way to troubleshoot voice calls and have visibility into their performance metrics. Since packet loss can be even more of a problem in networks using voice systems, if you’re juggling this issue, you may want to invest in a more specialized tool like VNQM over a broader packet loss monitoring solution like SolarWinds Network Performance Monitor.

VNQM communicates with a lot of different systems, which makes for a more comprehensive monitoring experience. However, it’s a good idea to know your way around Cisco and the Orion Platform on general principle. In fact, if you’re already working on Orion servers, you can equip VNQM with Orion Platform High Availability. This protects your system’s environment from OS crashes, network connectivity problems, and availability issues in your database.

The visual metrics in VNQM are my favorite features. The dashboard shows you an overview of the path each voice call takes in the form of a dial-graph, like a speedometer in a car. The visualization module shows the health of each path using color-coded statuses. These features make it easier to visually get a handle on VoIP monitoring across your entire network. Need more information? Read more about how VNQM helps monitor packet loss.

3. PRTG Network Monitor

Paessler PRTG Network Monitor

According to Paessler, you need three sensors to fix high packet loss. PRTG Network Monitor happens to provide them all, allowing you to ping packet loss easily. The Ping Sniffer Sensor measures your network availability, calculates the rate of packet loss for each device within your network, and breaks it down into a percentage—showing you past and present data in terms of dials and pie charts. The Quality of Service (QoS) One Way Sensor lets you keep an eye on network paths, which is a huge step toward reducing packet loss. Finally, the Cisco IP SLA Sensor measures packet loss specifically for Cisco devices, which will come in handy if you’re working with VoIP.

PRTG is also unique because most of its features focus on packet loss prevention. Prevent network overloads by selectively blocking traffic. This tool has a comprehensive alert system to let you know when warnings or unusual metrics have been detected in your network. Use this, combined with the other features, to track traffic or bottlenecking back to the source before it becomes a problem. Also, it’s one of the only two systems on my list to accommodate cloud-based services.

Like SolarWinds Network Performance Monitor, PRTG Network Monitor also has an auto-discovery feature. With auto-discovery, PRTG Network Monitor automatically divides your network into segments and categorizes them by pinging specific IP ranges. From this point forward, PRTG will automatically recognize all your connected devices and systems and create custom sensors for them. Auto-discovery is the shortcut to end all shortcuts, in my opinion. This feature saves time when it comes to configuration, so it’s quicker and easier to set up than other software options.

Overall, I like PRTG because it has a winning combination of visibility, scalability, and ease of use. You get everything you need to monitor your network in one piece of equipment—auto-discovery, network monitoring, NetFlow analysis, cloud monitoring, VMware monitoring, and database monitoring. The only cause of packet loss PRTG doesn’t account for is illegal tampering, but since it’s not very common, so it might not be an issue for you.

4. OpManager

ManageEngine OpManager

The tools I’ve mentioned would be useful for businesses of all sizes, from small and medium companies to enterprises, in terms of capabilities and price alike. But ManageEngine OpManager is focused on (and priced for) network management for large, multi-vendor IT enterprise networks. The key for this product is unification. For instance, OpManager wins the Best Dashboard award for its unique balance of inclusivity and individuality. This tool boasts a clean and sophisticated dashboard, offering end-to-end visibility of everything in your network infrastructure—from applications to printers to your entire wireless network. It does especially well in large organizations because the dashboard is customizable from user to user, without sacrificing continuity and shareability across the board. Out-of-the-box capabilities include network health monitoring, VoIP monitoring, Cisco NBAR reporting, network mapping, server monitoring, and more.

Regarding packet loss, OpManager uses SNMP to constantly monitor your network health across all devices. Controller displays send out alerts called “traps” that immediately pop up on the dashboard. Traps can also be configured to send out text alerts or email notifications to the user. There are separate alerts specifically for packet loss to not only tell you when there are instances of packet loss in your system but also what device is responsible for it. If you click on the notification, OpManager will bring you to a new page about the device and visually present performance metrics. With a few clicks, you can detect, isolate, and solve problems with packet loss.

5. Nagios XI

Nagios XI

Like every other network monitoring tool on this list, Nagios XI helps reduce packet loss by cataloging all the devices connected to your network and showing relevant performance metrics on a customizable dashboard. Dashboard options and settings can be viewed directly in your web browser.

Nagios XI is a strong contender worth checking out if you’re looking for help with packet troubleshooting. It records and stores performance data you can use to run different traffic scenarios in your downtime. This adds an entirely new dimension to troubleshooting and packet loss prevention. Knowing what device is causing packet loss and latency is one thing, but using the information to plan ahead dramatically reduces your risk of high packet loss in the future. Automatically generated capacity graphs make proactive planning easy. Custom reports offer specific details on network events. This tool’s alert systems send out notifications with outage details to users beyond the IT staff, keeping everyone informed and working toward problem resolution.

I commend Nagios Core for creating a tool that doesn’t sacrifice power for openness and flexibility. This product is powered by the Nagios Core 4 monitoring engine instead of SNMP, which is meant to allow for greater efficiency. It executes active and passive host checks, monitors network performance, checks service, collects system information, and more. Free plug-ins are available in the plug-in library, so you can get even more from this software.

Nagios XI is the most diverse tool on my list in terms of scope, which may or may not be a good thing depending on your system and price point. This software will monitor cloud-based networks, virtual systems, remote sites, wireless systems, and traditional WAN. On the other hand, Nagios XI is not as diverse when it comes to operating system compatibility because it only runs on CentOS and RHEL Linux. You can work around this if you have VMware or Hyper-V machines.

Nagios XI comes from the Nagios Core family of free, open-source software. Unfortunately, Nagios XI isn’t free. To get a user interface, GUI capabilities, and full functionality, you have to pay for either the standard or enterprise edition of Nagios XL. Nagios Core offers a 60-day free trial of this tool.

How to Fix High Packet Loss

Detecting, troubleshooting, and preventing packet loss is key to optimal network performance. Again, I want to stress there’s no surefire way to eradicate packet loss from your system forever. In fact, you’re bound to come up against it because, well, packet loss just happens. Networks aren’t infallible.

But there are steps you can take to improve your packet loss situation. I suggest starting out with a well-rounded tool like SolarWinds NPM, or if your packet loss mostly impacts VoIP, SolarWinds VNQM. With either of these, you’re getting the most bang for your buck, as these tools make it much easier to find out what’s causing your network to drop packets. You’ll get more visibility into packet loss, tools for troubleshooting, and an incredible range of additional network monitoring features. It’s worth it to try to mitigate the effects of packet loss, thereby increasing productivity and lowering your bandwidth requirements. Take advantage of the available free trials to find the right network packet loss monitoring solution for you.

What is packet loss, and how do you fix it?

There’s nothing more annoying than streaming your favorite show or film and the video keeps pausing, or your online game keeps stuttering, guaranteeing you’ll never win that victory royale. You can thank packet loss for that inconvenience.

What is packet loss, and how do you fix it? Read on to understand the problem, learn how to check for packet loss, and resolve the issue using a variety of methods.

What is a packet?

Think of a single email as a convoy of buses taking the class to Disney World. Each bus carries a portion of the overall student body — your email — along with information about where it’s going, where it’s from, and who is riding in the seats.

Networks essentially break your email — and all other data — down to these buses, or packets. In turn, the email you send to mom is not just one large file crammed through the internet pipes. Instead, it is a convoy of little data bits so everyone else can simultaneously send emails to mom too.

Once all buses reach the set destination, their payloads unload to recreate your message in Mom’s email client.

A single packet contains three main components:

Header

  • Source IP address
  • Destination IP address
  • Packet type
  • Packet number

Payload

  • Part of your overall data

Trailer

  • Error correction
  • End of packet info

The typical packet size is around 1,500 bytes, though the actual size may be circumstantial.

What is packet loss?

This is when one of our metaphorical buses does not reach Disney World.

Keep in mind that the bus convoy does not take a straight shot from your PC to the destination using a single freeway. Instead, the convoy takes the best route through multiple small towns. For instance, your browser’s connection may travel through 20 “stops” before reaching Digital Trends’ closest host server. That number may be greater or less, depending on your geological location.

In the same way that real-world roadways might disrupt the buses’ travel, though, sometimes packets face similar roadblocks and diversions. In the digital world, these traffic jams and reroutes can block some buses from reaching Disney World entirely. To prevent total disruption, packets are retransmitted, but the result translates to lag when playing online games, choppy video streams, and broken audio. Even web browsing can feel slow.

Network congestion isn’t the only factor

Packet loss isn’t primarily tied to network congestion. Other factors can cause issues too, such as:

Faulty hardware: Damaged cables, outdated modems and routers, and corrupt network card drivers can have a huge effect on network performance. For large companies, problematic network switches and firewalls will cause issues too.

Overloaded devices: In this case, network hardware is working harder than usual to handle all the traffic. These devices will temporarily hold packets until they have time to process and send them along. By the time a packet reaches its destination, it’s arrived too late. In some cases, it’s discarded.

Faulty software: Software running on a network device could have flaws — either originally or as a side effect from a recent update — requiring a reboot, patch, or complete reinstall.

Incorrect configurations: Network devices on a single link set at two different duplex modes (aka duplex mismatch) will assume a “collision” and discard or delay packets.

Wireless is less reliable: Due to the nature of wireless, packets have a better chance of vanishing into the digital void due to radio frequency interference, signal strength, and distance.

Security threats: Hackers may have control of a network device and are using it to flood traffic, blocking the destination. Another hack can cause network devices to intentionally drop packets.

How do you see packet loss?

If you are short of time, we suggest you visit this Packet Loss Test website and run the quick test to see what the results are on your network. For a more direct, thorough option, you can confirm packet loss by using the PowerShell (or Command Prompt) in Windows. Here’s to do that:

Step 1: Right-click on the Start button and select Windows PowerShell (Admin) on the Power Menu.

Windows 10 Open PowerShell

Step 2: Type ping followed by your router’s address (here’s how to find it). For instance, you may type:

ping 192.168.0.1

In the results, you will see a percentage next to Lost. As shown below, you want that number to be zero, meaning all packets reach their destination.

Windows PowerShell Show Packet Loss

However, that’s merely local. If you want to see the packet loss between your PC and a website, you’ll need to ping the web address.

For instance, type the following:

ping www.digitaltrends.com

In our test, results (currently) reveal zero packet loss, which is excellent given there are around 11 hops between this writer and the site’s host server. We performed this test using a PC on a wired connection.

Windows PowerShell Ping DT

However, by using the ping command, you’re only sending and receiving four packets. If you want a longer test, type the following instead:

Ping [insert address] -t

This test will continue indefinitely until you type the Ctrl + C key combination.

If you’re curious to see how many hops reside between you and the destination, type the following:

tracert [insert address]

Windows PowerShell Tracert

Typically the results show your current IP address along with the addresses of all the hops, but we removed them from the screenshot for security reasons.

On MacOS and Linux, you can use Terminal to run the Ping command. On MacOS, Terminal is either pinned to the dock, or you can typically find it in the Other folder on the Launcher.

MacOS Terminal Location

If you have Linux installed on a Chromebook, Terminal likely resides in the Linux Apps folder on the Launcher.

Chromebook Terminal Linux

However, like the Ping -t command in Windows, the test runs indefinitely, requiring you to type the Ctrl + C or Command + C key combination.

MacOS Terminal Packet Loss

In this case, we noticed packet loss when pinging Digital Trends with a MacBook Air on a 5GHs wireless connection. A second test pinging the local router showed no loss on our end. However, a third test re-pinging Digital Trends showed packet loss reduced to zero.

That said, random drops will happen — you just don’t want a continuous loss.

How do you fix packet loss?

Many issues causing packet loss may not even be on your end of the connection, but that doesn’t mean there aren’t some things you can do to try to improve it.

Restart your PC

Windows 10 Restart PC

The software running on your PC — whether it’s a driver, service, or application — can temporarily experience conflicts.

For instance, tabs in Google Chrome may consume 75% of your system memory, causing other services to throttle or crash. Rebooting can solve software issues in some instances that may influence network traffic.

Check your connections

Image of Ethernet port and lpug.

It might seem simple, but cables not quite plugged in properly can cause all sorts of problems, so it’s always worth checking. If you’re using a wired connection to your PC or laptop, unplug the cable and plug it back in again. Do the same with your router’s connection to the phone line to be doubly sure.

Update software

Windows Update Restart Now

Sure, updates can be annoying given they can bring you to a temporary standstill. But they’re also necessary, especially if older firmware contains flaws that cause the underlying device to lose your packets.

Make sure your PC’s operating system and network drivers are current, along with any network-accessing software you use, like Google Chrome and Mozilla Firefox.

Are you using a router? Be sure the firmware is current.

Move to wired connections

Wireless is great for moving about the house while listening to Baby Shark on your phone, but the connection can fall prey to radio frequency interference, signal strength, and distance. If you don’t see any real connection problems, then continue as usual.

But if you experience noticeable lag on a desktop, laptop, set-top device, gaming console, or similar device, moving to a wired connection might make a big difference. Not only do you get faster throughput, but most Ethernet cables are also shielded, which can reduce interference.

Turn off possible interference

For wireless devices, radio frequency interference can be an issue. That means you should switch off other wireless devices that are not in use, like wireless headphones, speakers, and even Bluetooth connections on smartphones and tablets. You could also consider using your router’s settings to change your wireless channel to reduce competition with your neighbor’s Wi-Fi.

If your devices are wired, make sure the cables aren’t draped near anything that can cause electrical and magnetic interference, especially if the cables are unshielded. If you’re using a Powerline connection, the electrical layout of your home or office can cause issues in addition to the “noise” created by large appliances.

Revisit Quality of Service settings

If other users in your home are competing with your connection and your work needs to take priority, you can assign bandwidth by digging into your router and adjusting the Quality of Service settings to prioritize traffic. That means allocating more bandwidth to your devices over others.

How you get to those settings is different in each router. Once found, you can create “rules” that allot specific traffic, services, or devices with a bandwidth level, like “highest” or “maximum.” Typically, you must set your network’s overall upload and download bandwidth less than your subscription’s allowance so the QoS component has room to make adjustments.

Restart everything

Somewhere between you and the World Wide Web, some digital gremlin ate your packets. While the issue may not reside on your end of the ISP’s connection, restarting everything is a great way to troubleshoot without digging into the details. Unplug your modem and/or router and hold the power button for 30 seconds, then plug it back in again.

For all other connected devices, rebooting is a good idea too — it never hurts to start this way. The local network assigns your device an address that may change when the network reboots (unless it’s static). You can try disabling Wi-Fi or unplugging the Ethernet cable for a moment, but you may still experience connectivity issues until you reboot.

Replace or upgrade your hardware

coaxifi router

Sometimes, old or defective hardware can be responsible for your packet loss. Upgrading your router or modem if you’ve had it for a while should be a last resort, but if you’ve tried everything else you can think of, it might be your best bet. In the end, even if it wasn’t entirely responsible for your packet loss, the raw performance boost your get will be worth it. We even have a vast selection of the best routers you can buy in 2020 in this guide. 

However, if you think your desktop network connection is what’s giving you problems, you can always try adding a secondary network card instead. While you can’t do this with most laptops and tablets, it might be just what you need for a desktop computer. 

When it comes to attacking technical issues, we understand that many people experience bouts of anxiety and confusion. However, you can rest assured that all issues which are tech-based have simple tech solutions. Packet loss is just one example of a tech-based complication that, once you discover the problem, you can solve easily. After all, it is very hard to solve an issue if you cannot identify the problem easily.

Deal with a DoS attack

Businesses often blame ongoing packet loss to Denial of Service (DoS) attack. IT experts determine IP addresses and send block requests. You can block these attacks and quickly detect them with modern cybersecurity. Switching to the cloud also decreases DoS attack consequences.

Install a network performance monitor

Trying to stay on top of everything that goes into packet loss is frustrating, especially if you want to move on and ensure that services continue to be available to your users. Network performance monitoring software is a top-tier solution that allows you to track your network’s health as a growing business. Solarwinds Network Performance Monitor and Progress WhatsUp Gold offer free trials to new users.

Overcoming packet loss – the bane of online gamers

Packet loss on gamers’ networks can cause serious knock on effects to gameplay, increase latency, and totally ruin the gaming experience for players and spectators alike. With the recent growth of gaming and esports leagues this can put serious money at stake for competitors who are competing on skill, but losing out because of network and traffic properties like packet loss.

Whether its multiplayer PC or console gaming, mobile games, or using one of the many game streaming services launched in the last few years, we’ve all experienced these dreaded effects of packet loss on our gaming experience which makes your game freeze or delays your inputs so you crash and burn.

Gaming as a spectator sport has also really taken off with steaming services such as Discord, Twitch, YouTube and many others allowing players to stream their game footage to friends, or the whole world.

What this means for game developers and network operators is that there’s a lot more real-time, and therefore low latency traffic going to and from each machine, which needs to be accounted for, and instead of one person being able to rage privately or to themselves, or friends on their voice channel, millions of spectators might be watching and seeing the effects of poor connectivity or poorly optimised game traffic affecting gameplay.

What can we do about packet loss?

From a practical standpoint, there’s not always much that can be done to stop packet loss occurring on a network. Short of requiring every gamer to be equipped with Gb/s fibre connections to the home, and a fully wired setup, which is great to have, but a) won’t necessarily mean there will be no packet loss, and b) isn’t a viable, practical or economical option for many people.

Traditionally networks used retransmissions to resend packets which were lost along the way, but this can add considerable delay, especially when many losses occur at once So to solve the problem, and also make sure that all gamers, with even those with basic connectivity can join the online gaming ecosystem to play and communicate with their friends around the world, the only viable option is to have a system that can operate flawlessly even in the presence of packet loss, and mask it from the user such that they don’t experience any drop outs, lag, delay, lost inputs and connection instability.

Game developers also need to be aware that packet loss rarely occurs at fixed intervals, losses are often bursty and unpredictable, which means that any solution needs to be able to adapt to varying levels of packet loss between players and the server.

FEC is the solution

Next generation FEC codes are an easy to implement solution to overcome detrimental effects of packet loss in gaming. The trick is having a solution which can adapt to the changing network conditions, so when packet loss does start to rear its ugly head, the system will automatically generate repair traffic to mask the effects of packet loss and let the user continue to enjoy the application.

When packet loss increases, the FEC needs to be able to ramp up the amount of repair included, and when no packet loss occurs, the FEC should be able to turn off to save bandwidth and CPU resources.

Steinwurf’s FEC Solutions are adaptable

Classic FEC schemes like Reed Solomon don’t have this ability to adapt on the fly to changing network conditions, but Steinwurf’s RLNC based FEC codes make it easy to operating across real world networks with packet loss variance.

If we couldn’t adjust the FEC on the fly, then, except in the rare case when the gamer’s packet loss rate exactly matches the repair rate of the FEC, you would always either have too much repair, wasting bandwidth, or too little repair, meaning not all packet loss is masked, which breaks the gaming experience.

By using Steinwurf’s Low Latency FEC solutions such as Rely, game developers can ensure that gamers dont get left behind by having too little repair traffic to mask packet loss, and that hardware and networks are running efficiently by not overloading the service with excess repair when it isn’t necessary.

How it works for Game Streaming Services

To understand how this plays out visually, our game streaming demo shows the most latency sensitive gaming application, when teh players’ console is in the cloud, and being operated remotely from the home, or even on the go via mobile. For action heavy games which require constant interaction between the player and the game packet loss can be a total killjoy. If the game service adds an optimised FEC into the mix though, the gamer is none the wiser to packet loss, and has one less reason to leave the service behind and can keep playing, and subscribing to the streaming service.

Gaming on Xbox One online allows you to go up against players from all over the world, have fun with your friends and meet new people. Unfortunately, this experience often comes with a long list of challenges, with one of the most frustrating ones being packet loss.

The higher the packet loss, the more hindered your gaming session will be. If you find your sessions lagging or crashing, what can you do to fix packet loss on Xbox One?

You can manually fix the packet loss issue by restarting your router, tailoring user settings, resetting your Xbox, or, if your schedule allows it, avoiding peak time sessions when gaming. Alternatively, you can also improve packet loss with a VPN and enjoy a faster and more stable connection. 

What is Xbox One High Packet Loss?

When playing online games or streaming content through your Xbox One console, you’re continually exchanging data bundles (packets) with the server you’re accessing. Any data that doesn’t make it to its destination is called a packet loss. Packet loss is one of the most severe issues that can affect your connection and make your gaming experience frustrating. High packet loss can manifest in several ways:

  • Connection timeouts
  • Network crashing
  • High ping
  • Latency issues (network jittering)

What Causes Packet Loss on Xbox?

High packet loss on Xbox mainly arises because of network congestion. In other words, this problem occurs when the network can’t accommodate the user traffic and starts losing data in transit in an effort to keep the entire network from crashing.

Apart from network congestion as the most common cause of packet loss on Xbox One consoles, packet loss can also occur because of server-side leaks and improper configuration. 

Additionally, the issues can come from the user’s end as well. Wrong cables, poor channel signal, or network interference can all cause your connection to drop data packets between your console and the game server.

Why Do I Have Xbox One High Packet Loss on a Wired Connection?

If you have high packet loss and your Xbox One is connected to a wired connection, the problem might not be in your network connection but the hardware instead. A faulty router might be causing a delay in your network or slowing down your connection performance. 

What is a Good Packet Loss for Xbox One?

While no gamer wants to experience packet loss on his Xbox One, keep in mind that almost every network encounters packet loss. Although we don’t want to say that there is such a thing as “good packet loss”, there are specific ranking standards that are used to measure packet loss for Xbox One:

  • Packet Loss around or less than 1% is considered good.
  • Losses between 1% and 2.5% are considered acceptable.
  • Packet Losses upwards of 10% are deemed as significantly negative.

Can I Check Packet Loss on My Xbox One?

If you think that your network is underperforming because of high packet loss, the best way to make sure is to check it in your Xbox One network statistics directly. Most users aren’t aware of this option on their Xbox devices, but the process is straightforward. Here’s a quick step-by-step guide on how to check packet loss on your Xbox One:

  1. Open the guide by pressing the Xbox button.
  2. Choose the Profile & System tab.
  3. Go to Settings > General > Network Settings
  4. Select the Test Network Speed & Statistics
  5. If the results show you have upstream/downstream packet loss, contact technical support for further assistance.

Xbox One Troubleshooting High Packet Loss

Manually Fix the High Packet Loss

Since packet loss issues on Xbox One can come about for various reasons, you can use many methods to manually resolve this problem. Here’s are the most effective ways to fix packet loss on your Xbox One manually:

  • Restart your Router – Although the classic “restart your router” IT tip has become a meme by this point, it’s still a very effective way of resolving many connection issues. Starting up your router again can help resolve little bugs and issues that may have affected your connection.
  • Disconnect your Xbox One – In line with the previous tip, manually disconnecting your Xbox One from your home network can also help resolve the issue of high packet loss. This is because it will allow your device to reboot without any of the pre-existing errors it had on your connection. If this doesn’t resolve the issue, applying a hard reset might prove more successful.
  • Switch to a Wired Connection – The wired connection in your home is inherently much faster than your wireless connection. Connecting your Xbox one directly to the router with an Ethernet cable will help it transmit the data at a much higher speed.
  • Avoid Gaming at Peak Server Times – The least fun way of fixing high packet loss, but also a very effective one. Avoiding peak session times when the servers are overcrowded pretty much guarantees you a smoother and more stable gaming experience.

Use a VPN to Fix High Packet Loss

If the problem arose due to your local connection’s inefficiency or because your ISP is throttling your bandwidth, a VPN may help improve your network’s speed and resolve packet loss issues on your Xbox One.Here’s how to fix packet loss on Xbox One with a VPN:

  1. Sign up with a VPN (NordVPN is best for gaming)
  2. Connect your router or your PC to the VPN
  3. If you choose the latter option, make sure to link your Xbox One to route the connection through your PC.
  4. Launch up the game and enjoy!

Note that, in some cases, using a VPN for gaming can slow down your connection and lead to higher ping. However, this is only a problem if you connect to a server that is far away on the other part of the globe. If you stick to nearby servers or those without much traffic, you won’t experience any noticeable adverse effects on your network performance.

If you’re considering purchasing a VPN for gaming, NordVPN can help bring your online gaming experience to the next level. Aside from being an effective tool for fixing Xbox One packet loss, NordVPN is useful for various gaming purposes. It can also bypass ISP bandwidth throttling, unblock servers in other countries and keep your data traffic safe from online threats that persist in gaming, namely DDoS attacks.

Conclusion

XBox One high packet loss can be fixed by simply restarting either the router or your device. Sometimes, when this does not work, this usually means that your ISP can throttle your gaming traffic. A VPN in this case would be the best solution as it can bypass ISP throttling and fix the packet loss.

Here are the best VPNs to try to lower ping and have a better gaming experience:

Loss gaming packet

What is Packet Loss and How Can You Avoid It While Gaming?

In this post, we look at some causes of packet loss. More importantly, we share how to can get rid of packet loss and avoid this game-killer at all costs.  

There is literally nothing worse than sitting down with your favorite game, logging into a server with your buds, and then… nothing. Your avatar is lagging, you’re teleporting around the map all herky-jerky, and sometimes you’ll even get kicked out of the game completely. It takes what should be a fun and immersive experience and makes it, well, a pain in the butt.  

That connection-issue is something called packet loss. Don’t worry if you’re not up on the lingo, this term has only been around for the last half-decade. That said, you’ve definitely experienced the effects of packet loss if you’ve ever tried to play Fortnite or League of Legends and had less than stellar results. So what can you do? Well, the good news is that whether it’s Rocket League packet loss, Fortnite packet loss, or even Modern Warfare packet loss -- the answer is pretty much the same. Read on for some ways to identify packet loss, how to check packet loss, and most importantly: how to fix packet loss. But before we get into all that, let’s go back to the basics.  

What is High Packet Loss? 

In its most basic form, high packet loss is an occurrence that happens between your game console and the server you’re using. There could be several reasons for this, but what ends up happening is that data is lost between these two destinations. When that happens, you get things like random character teleportation, missing time, or even a boot from your gaming server. We’ve heard people call this an “unsatisfactory experience." We’d go with a different word -- unacceptable. 

So what is a packet? It’s exactly what it sounds like, a small grouping of data that is sent from your gaming console to the server. When that packet is lost, the server can’t react or utilize the data you’re sending. 

How to Check for Packet Loss 

Before you can figure out how to fix packet loss for Fortnite (or any other game), you need to know what to look for. Here are some sure-fire signals that your packets aren’t getting to the server.  

Lagging or Freezing 

If your game experiences are extremely choppy or even feature frequent freezes, then you could be experiencing packet loss. This can be especially true when you have large amounts of data from a large map, tons of players, or intense graphic requirements. That’s a lot of packets! 

Teleportation (for you or others) 

You know that thing when you’re walking around a game map in Apex Legends and all of a sudden every player on-screen disappears and then reappears in a different location? That could be due to packet loss. Often it really messes your game up. You’ll line up the perfect shot or be near an objective, and all of a sudden everything seems to teleport to a different location. Not only is it frustrating, but it can also make a game nearly unplayable. In really bad cases, you may even be booted from your game.  

How to Fix Packet Loss 

Often your ISP (internet service provider) is to blame for your packet loss. This could be because you don’t have a fast connection or for a few other reasons, such as throttling. Here are some solutions for how to stop packet loss, depending on your situation. We promise these are better solutions than throwing your controller at the wall. 

Get Faster Internet 

One of the best ways to fix packet loss is to up the Mbps going to your console. That allows your console to communicate with the game’s server faster -- lessening the likelihood that you’ll experience packet loss. If you’re dealing with much less than 100 Mbps, it might be worth looking at an upgrade. 

Use An Ethernet Cable 

Wi-fi is convenient and has certainly come a long way, but it’s still not as good as a hardline connection. If you have fast internet but are still experiencing frequent lagging in games, move to an ethernet connection from your router to your console. The cable connection can often eliminate weird gate issues between your router and the game.  

Use Outfox 

Outfox’s optimized gaming network was designed to improve experience for you, the gamer. We provide a fast, stable network connection as an alternative to your non-Outfox connection, and will tell you when our network versus your connection is fastest. Outfox helps you find the fastest path to the game server, reducing pesky issues like packet loss (not to mention ping and lag). Give it a try today!

OK, no excuses. Using these tips, you’ll never be able to blame your bad kill ratio on your internet again. Go forth and be a gamer god!

  7. Replace outdated or deficient hardware – Upgrading your network infrastructure allows you to get rid of deficient hardware altogether.
  8. Use QoS settings – Prioritize your network traffic based on the applications that are most important. For example, prioritize voice or video traffic.

What is packet loss?

Packet loss refers to any packets of data that are lost or dropped in transit during travel across a computer network.

Packet loss could be due to a failure or an inefficiency of a component that carries data across a network, such as a faulty router, a loose cable connection or bad wifi signal strength.

Lost packets can also be intentional, for instance when it is used to restrict throughput during VoIP calls or video streams so as to avoid time lags, particularly during times of high network congestion. This results in lower quality data streams and calls which negatively affect user experience. To fix packet loss and keep high latency, you need to determine which parts of your network are contributing to the problem.

What causes packet loss?

Causes of Packet Loss

Packet loss is less likely on private, wired networks, but highly probable on long-distance internet connections. The IP philosophy of passing data packets across networks gives each router the decision on where a packet should be passed to next. The sending computer has no control over the transfer speed or the route that the packet will take.

Router packet loss

The reliance on individual routers to make routing decisions means each access point on the route must maintain a database of preferable directions for each ultimate destination. This disconnected strategy works most of the time. However, one router cannot know instantly if another router further down the line is overloaded or defective.

All routers periodically inform their neighboring devices of status conditions. A problem at one point ripples through to recalculations performed in neighboring routers. A traffic block in one router gets notified to all of the routers on the internet, causing all routers to recalibrate paths that would otherwise have passed through the troubled router. The chain of information takes time to propagate.

Rerouting overload

Sometimes a router will calculate the best path and send a packet down a blocked route. By the time the packet approaches that block, the routers closer to the problem will already know about it and reroute the packet around the defective neighbor. That rerouting can overload alternative routers. If the defect on a router prevents status notifications from being sent out, then the packet will be sent to that router regardless.

In short, the further a packet has to travel, the more routers it will pass through. More routers mean more potential points of failure and a higher likelihood that dropped packets will occur.

When is packet loss too high?

You will never reach a point where your company’s network infrastructure achieves zero packet loss. You should expect this performance drag when making connections over the internet, in particular.

Once you understand the reasons for packet loss, keeping the network healthy, packet recovery becomes an easier task. Install a network monitor to prevent equipment failure, security risks, and system overloading that escalates packet loss to critical conditions.

Packet loss costs your business money because it causes extra traffic. If you don’t deal with packet loss, you’ll have to compensate by purchasing extra infrastructure and higher levels of internet bandwidth usage than you would need with a well-tuned system.

The best tools fix packet loss

The more tightly knit a network, with better routers and connections in place, the less likely it is to face packet loss. But invariably many communications happen using the Internet Protocol, and not all hops are known along the way.

Tools that monitor your network endpoints can help you detect, troubleshoot and fix packet loss.

The endpoints are in the best position to work out if re-transmission of dropped packets should take place. This means that we should always anticipate some level of packet loss and therefore packet recovery in data communications. Fortunately, some very effective network monitoring solutions are available today.

What should you look for in tools to fix packet loss?

2. Paessler Packet Loss Monitoring with PRTG (FREE TRIAL)

Paessler PRTG Cisco IP SLA Sensor for Packet Loss

Paessler is a significant player in the network monitoring software sector and it puts all of its expertise into one killer product: PRTG. The company prices its product by a count of sensors.

A “sensor” is a network or device condition, or a hardware feature. You need to employ three sensors to prevent or resolve packet loss:

  • The Ping test sensor calculates packet loss rate and trip time at each device.
  • The Quality of Service sensor checks on packet loss over each link in the network.
  • The third is the Cisco IP SLA sensor that only collects data from Cisco network equipment.

Paessler PRTG Packet Sniffer Sensor

The ongoing system monitoring routines of PRTG head off conditions that cause packet loss.

  • First of all, you need to ensure that no software bugs or hardware failures will cripple the network. PRTG uses SNMP agents to constantly monitor for error conditions on each piece of hardware on the network.
  • Set alert levels at the processing capacity of each network device and marry that to a live monitor of the network’s throughput rate per link.

The build-up of traffic in one area of the network may cause overloading on the related switch or router and in turn cause it to drop data packets.

The PRTG system monitors application performance, too. You can prevent network overloads if you spot a sudden spike in the traffic generated by one application just by blocking it temporarily. You can also track the source of traffic back to a specific endpoint on the network and block that source to head off device overloading.

Paessler PRTG QoS One Way Sensor for Packet Loss

The dashboard of PRTG includes some great visualizations, which include color-coded dials, charts, graphs, and histograms. The mapping features of PRTG are impressive and offer physical layout views both on the LAN and across a real-world map for WANs. A Map Editor lets you build your own network representations by selecting which layer to display and whether to include the identification of protocols, applications, and endpoints.

Paessler PRTG’s monitoring extends into the Cloud, will enable you to monitor remote sites, uncover network problems, while also covering wireless devices and virtual environments. You can install PRTG on the Windows operating system or opt to access the system over the internet as a Cloud-based service. Paessler offers a 30-day free trial of PRTG.

3. ManageEngine OpManager

OpManager dashboard

OpManager features a very sophisticated dashboard that manages to crowd in a lot of information without overwhelming the viewer. You can customize the dashboard and make different versions for different team members. The installation process ends with a network discovery phase, which populates the OpManager system database. The monitor builds a graphical representation of your network that can extend to WANs and wireless equipment. If you have virtual environments, OpManager maps both the virtual and physical elements of your system.

The comprehensive network monitoring system uses SNMP to continue monitoring the health of all connected devices on the network. The SNMP system gives device agents the power to send out alert messages called “traps.” The controller displays these alerts on the dashboard immediately and can also be set to issue notifications by email or SMS. This monitoring system helps prevent any emergency performance issues that cause packet loss.

The alert logging system offers you the easiest way to detect and resolve issues that result in packet loss. One of the alert conditions is packet loss. That alert is tied to a specific network device. On clicking on the notification, the OpManager dashboard takes you to a page about that piece of equipment and shows performance metrics in visual formats. This gives you a quick way to check which condition caused the increased packet loss rate.

If no aspect of the router’s performance shows you problems, you can also click through to read the configuration changelog. If raised packet loss rate coordinates with a configuration change, you can roll back the settings of the device to its state before those changes to see whether that resolves the problem.

Key Features

  • SNMP monitor
  • Network device statuses
  • Network discovery

OpManager gives you all the information you need to prevent, resolve or reduce packet loss with just a few clicks. This system can be installed on Windows or Linux and is available for a 30-day free trial.

4. Nagios XI

Nagios XI screen

Nagios Core is a free and open-source program. The only problem is that no user interface is included. To get full GUI controls, you must pay for the Nagios XI system.

Like all of the other recommendations on this list, Nagios XI discovers all of the devices connected to your network and lists them on the dashboard. It will also generate a map of your network. Ongoing status check head off potential packet loss-provoking performance problems.

Statuses are checked by the proprietary Nagios Core 4 monitoring system rather than SNMP. However, Nagios can be extended by free plug-ins, and an SNMP-driven monitoring system is available in the plug-in library. Traffic throughput rates, CPU activity, and memory utilization appear as statuses on the dashboard include. By setting alert levels on these attributes, you can get sufficient warning to prevent overloading of each of your network devices.

A Configuration Management module checks the setup of each device on the network and logs it. The log records changes made to those configurations. If a new setting impacts performance, such as increased packet loss, you can use the Configuration Manager to instantly roll back settings on a device to an earlier configuration.

The dashboard of Nagios XI includes some very attractive visualizations with color-coded graphs, charts, and dials. You can customize the dashboard and create versions for different team members as well as non-technical managers who need to stay informed.

The Nagios XI package includes all the widgets needed to assemble a custom dashboard through a drag-and-drop interface that makes it easy to stop packet loss. The system comes with standard reports and you can even build your own custom output.

Nagios records and stores performance data, so you can operate the interface’s analysis tools to replay traffic events under different scenarios. The capacity planning features of this system will help spot potential overloading that would cause packet loss.

Nagios XI will cover virtual systems, cloud services, remote sites, and wireless systems as well as traditional wired LANs. You can only install this monitor on CentOS and RHEL Linux. If you don’t have those but do have VMware or Hyper-V machines, you can install it there. Nagios XI is available for a 60-day free trial.

Packet Loss FAQs

What causes packet loss on a network?

The most common cause of packet loss on a network is overloaded network devices. Switches and routers will drop data packets if they cannot process them in time. Other major packet loss causes include faulty equipment and cabling.

How do you calculate packet loss?

Take a count of the number of packets sent at one point on the network and the rate of packets received at another node. Subtract the number of packets received from the number of packets sent and divide the result by the number of packets sent to get the packet loss rate.

Why do I have packet loss with Ethernet?

Ethernet cables will lose packets if there is heavy electromagnetic interference nearby, if part of the cable is damaged or if the connectors at each end are loosely plugged into equipment.

Does packet loss affect ping?

Packet loss is one of the factors measured by the Ping utility. However, what is commonly referred to as “ping” is the round-trip time (RTT). This is not directly changed by packet loss – the two metrics are factors that influence response times over networks.

Is some packet loss normal?

Some packet loss is to be expected and isn’t usually a major problem. The rate of packet loss to be expected greatly depends on the size and reliability of the network. The greater the number of hops a transmission needs to take, the greater the risk of packet loss. There should be a lot less packet loss experienced on a private network than on the internet. Also, small networks should experience less packet loss than large networks in normal conditions. In general, a packet loss rate of 1 to 2.5 percent is seen as acceptable. Packet loss rates are generally higher with WiFi networks than with wired systems.

Is 2% packet loss bad?

Any packet loss will slow down response time but on a public medium like the internet, an expectation of 100% delivery success is unreasonable. Be prepared to encounter at least a little packet loss and anything below 5% is considered acceptable.

Can a VPN help with packet loss?

In truth, a VPN can’t do much about packet loss if the loss is caused by poor performance by the ISP’s equipment or an overloaded router. All a VPN does is encrypt packets and alter the path that a connection would normally take to reach a specific destination by diverting the connection through a mediating server. Those packets still have to pass through your gateway to the internet and the equipment of your ISP. If faults at those points are causing packet loss, they will drop packets regardless of where they are going or how they have been encrypted.
