Everyone may occasionally experience packet loss, regardless of the ISP, including Xfinity users.

What causes Xfinity packet loss?

  • Network congestion (e.g. during peak hours)
  • An unstable Internet connection
  • A faulty router with bad Wi-Fi settings
  • Bandwidth throttling caused by Xfinity
  • Software or hardware errors
  • Cyber-criminal activities such as DDoS attacks

It can be challenging to pinpoint the exact root of the problem. However, it’s essential to go through the necessary steps to isolate the issue.

How can I fix Xfinity packet loss?

1. Check your Internet connection

The easiest way is by checking the quality of your Internet connection. If possible, temporarily switch to another network to see if you’re still experiencing packet loss over Xfinity.

If the other network is also controlled by Xfinity, it doesn’t automatically mean your Internet connection is the culprit. It could still be the ISP’s fault in case it’s intentionally slowing down your bandwidth.

The easiest way is to temporarily switch to a mobile data plan operated by another ISP. It’s also a good idea to regularly run speed tests on your computer using specialized tools like Ookla’s speed tester.

2. Switch from Wi-Fi to Ethernet mode

Temporarily switching to wired mode should determine if the Xfinity packet loss issue is caused by a bad router configuration.

If that’s the case, then you could reboot your router, move your device closer to the router to improve the connection signal, and check the admin panel of your router to optimize network settings.

3. Update your security software

We hope you’re using security software to keep your computer safe from hackers. If you’re on Windows 10, Windows Defender should be enough to protect you from the perils of the Internet.

Otherwise, we strongly recommend getting equipped with a powerful anti-malware solution that comes with a real-time engine for your device.

It’s equally important to keep these tools updated to the latest version in order to benefit from the latest security patches. When it comes to Windows Defender, it means running Windows Update.

4. Use a VPN

Here’s how to easily use a VPN to fix Xfinity packet loss in three steps:

  1. Get a premium VPN service
  2. Download and install the VPN on our device.
  3. Launch the app and connect to a VPN server.

A VPN comes with numerous benefits. Because it’s built to change your IP address and geo-location, this can help you bypass bandwidth throttling in case Xfinity is slowing you down because of streaming or torrenting, for example.

You can use a VPN to protect your online privacy and prevent Xfinity from learning what you do online. In turn, it will not be able anymore to limit your network connection due to flagged activities.

5. Reset Internet settings

  1. Launch Command Prompt as admin
  2. Paste the next lines (press Enter between each line)
    • ipconfig /flushdns
    • ipconfig /registerdns
    • ipconfig /release
    • ipconfig /renew
    • exit
  3. Restart your computer

The commands above help you easily flush your DNS servers to reset Internet settings. It’s a quick and easy method to try fixing Xfinity packet loss.


To summarize, you can fix Xfinity packet loss by checking your Internet connection and by temporarily switching from wireless to wired mode.

You can also update your security software, use a VPN service, and easily reset Internet settings with a few lines of code in Command Prompt.
