Packet loss is a term that many people in the telecommunication world understand. There are too many lost packets of data between one device and another, which causes an audio or video call to degrade quality. Packet loss is when data packets are lost during the transfer process. It can cause audio quality to be poor, and it is essential to fix packet loss for better VoIP quality. A packet is a container for objects and materials that will be conveyed to other people. If you lose the package, you’ll lose the contents as well. This is comparable to packet loss. At the top network layer, data is sent in packets to enable the recipient to utilize or arrange the information. When this information does not arrive properly, it is called packet loss. Do you know how aggravating it is to be watching your favorite show on Netflix when the screen keeps pausing? Or when the video stutters unexpectedly during a competitive game with your friends? That’s a case of packet loss. A variety of factors may cause packet loss. Everything from network congestion to overloaded devices to malfunctioning software and hardware must be monitored regularly. Continue reading to learn how to identify, diagnose, and resolve packet loss.
What to Expect When Attempting to Recover Packet Loss?
Although there is no way to guarantee a packet loss rate of 0% at all times, you may take specific steps to reduce it to build a high-quality network. The steps to resolving packet loss are as follows:
- Step 1: Use your computer’s operating system to detect packet loss.
- Step 2: Determine the Root Causes of Packet Loss
- Step 3: Addressing the Various Causes of Packet Loss
- Step 4 — Make Additional System Changes
The Good
It is pretty simple to detect packet loss in your system. While you must take additional steps to get your router’s IP to type the ping command, the results are instantaneous. If you want a quicker answer, you may use an online tool to calculate the percentage of packet loss. Fixing packet loss is also not extremely difficult for only a few reasons. The possibilities are clogged bandwidth, malfunctioning hardware or software, broken cables, or network issues. The only exception is when your network is under a DoS attack, but other than that, figuring out what’s going on won’t take long. Furthermore, you may not have to deal with these assaults if you use a reputable VoIP phone provider and a network performance monitor. And after you’ve done that, you’ll be able to solve problems swiftly.
The Bad
While determining the source of packet loss is simple, resolving some of these issues may be challenging. For example, if your program isn’t operating correctly, you may have to wait for a developer to provide an update to fix the problem. Most of the time, an instant repair isn’t accessible. Therefore, you’ll have to find an alternate software solution that doesn’t cause packet loss. Changing the hardware isn’t always the best solution. It costs money to upgrade or replace your modem, router, and wires, which may be a problem for companies on a limited budget. There isn’t much you can do since replacing hardware is generally the final step when everything else fails to remove or reduce packet loss. You’ll have to cope with DoS assaults if a cybercriminal targets you. And if you don’t fix the issue right away, your network will crash. To counter such assaults, you’ll require comprehensive cybersecurity, which isn’t cheap.
Steps to resolving packet loss:
Step 1: Use your computer’s operating system to detect packet loss.
Packet loss may be detected in two ways. The first step is to go to this website and do a packet loss test. Then, to observe the results on your network, you only need to conduct a brief test. This approach is ideal if you’re short on time and want to see results quickly.
The alternative way is more extensive and direct, requiring you to examine packet loss using the Command Prompt or PowerShell in Windows or the Terminal folder on Macs.
- In Windows, Packet Loss Is Visible
Select Windows PowerShell (Admin) from the displayed menu by right-clicking on the Start button.
Then enter ‘Ping’ followed by the IP of your router (you can find the router address through this guide). Loss has a percentage next to it in the results. Something along these lines:
This value should be 0, indicating that all packets have arrived at their intended destination. Keep in mind that this is just a local test. You’ll need to use a separate command prompt to observe the packet loss between a website and your PC. Ping www.thewebsitename.com will be the new prompt. It’s important to remember that the ping command only sends and receives four packets. If you want a more thorough examination, enter www.thewebsitename.com -t ping. This test will run until you stop it using the Ctrl + C key combination.
- Packet Loss in Mac OS X
To launch the command prompt on a Mac, go to the Terminal folder and type Ping 127.0.0.1. This folder may be found pinned to the dock (the bottom menu bar that appears when you first launch your device) or in the Other folder after clicking on the Launchpad icon.
- In Linux, Detecting Packet Loss
To launch the command prompt on Linux, you must also select Terminal. The terminal may be found in the Launcher’s Linux applications folder. In this scenario, the command will be identical to macOS (Ping 127.0.0.1).
The test will continue forever after you execute the ping command, precisely as the ping -t command in Windows. To stop the test, use the Ctrl + C or Command + C key combination, depending on your device. You’ll note that sporadic drops are unavoidable when doing these tests, and that’s OK. The issue is that there is a constant loss of packets.
Step 2: Determine the Root Causes of Packet Loss.
Four main factors may cause packet loss. Below, I’ll explain how to recognize each of them.
- Bandwidth Congestion Detection
Congestion is unavoidable, particularly during peak times of the day. However, high latency, higher than typical loss rates, and jitter increases are all symptoms of a crowded network, so they’re so wrong.
To quantify congestion and understand how it varies throughout the day, monitors your network’s latency, loss rates, and jitter. Congestion may last a few minutes if you’re fortunate, but it might sometimes take longer.
- Faulty Network Wire Detection
Wired networks have to deal with a lot of data. If they begin to degrade, you will experience packet loss as data is transferred inefficiently—exactly why the ethernet cables should be checked. If you suspect that wires are the source of your packet loss, carefully inspect your lines for evident outside damage. Even filthy fiber connections may cause packet loss. Secure your network connection points as well.
- Identifying Software Problems
Using a software tool is all about transferring data. As a result, if it stops operating correctly, packet loss may occur. A programming mistake might lead the software to become dysfunctional, resulting in unexpected network behavior. This might be due to a problem in the program or a long-overdue upgrade. A sluggish connection is a sure sign of potential software problems. To check how the programs communicate with the network, open Task Manager on your computer. After that, see whether the program or application in question consumes a lot of bandwidth even when it isn’t in use. Task Manager has a pane that displays the application history for the last 30 days. You may compare the service to the delay you’re experiencing using the data.
- Weak Wi-Fi Networks Detection
Weak Wi-Fi signals obstruct the flow of data packets throughout your network. Even radio frequency interference or transmission through substantial barriers may be destructive. Because wireless networks or Wi-Fi suffer from more setbacks and interference than traditional connections, you should examine your Wi-Fi status to figure out where the packet loss is coming from. Use your device to access the internet. There will be multiple lines here that show the strength of your Wi-Fi.
A poor signal indicates that the network is overburdened and unable to support all of your devices appropriately.
Step 3: Addressing the Various Causes of Packet Loss.
After you’ve figured out how to identify the four sources of packet loss, the next step is to figure out how to cure it. Then, I’ll discuss how to solve packet loss problems depending on the reason, same as how I explained detection.
- Getting Rid of Bandwidth Congestion
You can determine the most crowded time of day by monitoring your network performance. When your network is less busy, you can quickly rectify packet loss by sending information out. Although this isn’t the ideal option for VoIP connections, you may arrange calls and conferences during off-peak hours. To reduce packet loss, experts recommend boosting the capacity of the relationships experiencing packet loss. In addition, you may change the network’s configuration to prioritize real-time traffic. This will not completely eradicate the congestion, but it will lessen the likelihood of a dip.
- Troubleshooting Networking Wires
The apparent remedy is to replace your broken cables with new ones to provide a more reliable connection route (duh!). However, here are a few additional pointers to assist you to prevent future problems with broken wires:
- Ensure that the wire jacket has a high level of physical integrity and is long-lasting. It should last a long time.
- Select the appropriate wire category. For example, a Cat 5 is reasonable for small enterprises, but organizations with internet connections faster than 1 Mbps would require a greater variety.
- If you have many wires going together, acquire a shield to avoid signal interference.
- Troubleshooting Software Issues
If your program uses too much bandwidth on your network, you should either restart it or reset your device. The program may be tough to change at times, but you’ll get an update to improve performance speed in most situations. If the program remains unstable, you may either wait for the development team to provide an update to fix the problem, or you can choose a different option that doesn’t result in packet loss.
- Wi-Fi Networks That Aren’t Working.
To boost the signal, it’s important to reboot your Wi-Fi router. If just one device isn’t receiving a signal, reset it to check if it gets a more robust call. A Wi-Fi analyzer may also see whether a problem with the Wi-Fi settings causes packet loss. If this is the case, configure your device to connect to a different Wi-Fi network or utilize a cable connection.
Step 4 — Make Additional System Changes.
Packet loss in your system might be caused by various factors, including old hardware or network threats. In both cases, the corrective action will differ, so understanding the specific course of action is critical.
- Replace or upgrade your hardware
Old or damaged hardware is one of the leading causes of packet loss. So if you’ve done everything else and still can’t get rid of packet loss, upgrading your modem or router could be your best choice.
If you believe your desktop network connection is the root of the issue, you may install a second network card rather than purchasing new gear. While this may not be practical with most laptop and tablet versions, it is ideal for desktop PCs. Another option for minimizing packet loss is to hire a professional IT staff (if you can afford one) to keep up with VoIP devices and servers.
- Defend against network attacks
Check if a sure IP address is flooding traffic to your network if you suspect a substantial and persistent packet loss due to network assaults such as Denial of Service (DoS) attacks. DoS attacks seek to make your network ineffective or even crash it by flooding it with more requests than it can manage. As a result, your network will be slower than usual, causing stuttering and jittering in your files and webpages and stuttering and jittering in your VoIP conversations. Block the IP address that is causing problems on your machine. Your network will eventually return to normal. Investing in more robust cybersecurity might help you avoid being harmed by these assaults. Another option is to use cloud services, which may help prevent or mitigate the consequences of DoS assaults.
