How to get Windows 11 25H2 build 26200.7019 to stop losing internet access after 24 hours of run time

I have three different computers running Windows 11 that are experiencing this same problem. I first noticed it in October 2025. After running for about 24 hours, the computer stops being able to load websites from any browser (Edge, Chrome, Vivaldi, Firefox, Arc). Resetting the wireless adapter temporarily fixes the problem for about 10-15 minutes, then it reoccurs and the only way to fix it is reboot the computer. The reboot fix only lasts for another 24 hours. This still occurs after I set the computer to a static IP address and provisioned the IP address in my home wireless router. The issue still occurs with a direct ethernet cable connected to my router. The issue does not occur on the other 60 devices connected to my router that are not running Windows 11. The issue does not occur on my computer running Windows 10. I have tried using Copilot to create Powershell scripts to solve the problem. The only thing that works is pinging a website once per second and then if the ping fails 300 ties in a row, force the computer to reboot. This is not a good solution as it is disruptive to my workflow. How do I fix this?

    It appears that you are experiencing a connectivity issue with Windows 11, version 25H2 build 26200.7019, where the internet access drops after approximately 24 hours of runtime. While the specific cause of this issue is not detailed in the provided context, there are a few general troubleshooting steps you can consider to potentially resolve the problem:

    1. Update Network Drivers: Ensure that your network drivers are up to date. You can do this by going to Device Manager, finding your network adapter, right-clicking it, and selecting "Update driver."
    2. Check Power Management Settings: Sometimes, power management settings can cause network adapters to behave unexpectedly. In Device Manager, right-click your network adapter, go to Properties, then the Power Management tab, and uncheck "Allow the computer to turn off this device to save power."
    3. Reset Network Settings: You can reset your network settings to default. Go to Settings > Network & Internet > Status > Network reset. This will remove and reinstall all your network adapters and set other networking components back to their original settings.
    4. Run Network Troubleshooter: Windows has a built-in network troubleshooter that can help diagnose and fix connectivity issues. Go to Settings > Update & Security > Troubleshoot > Additional troubleshooters > Internet Connections.
    5. Check for Windows Updates: Ensure that your system is fully updated. Go to Settings > Update & Security > Windows Update and check for updates. Sometimes, connectivity issues are resolved in newer updates.
    6. Review Firewall/Antivirus Settings: Occasionally, firewall or antivirus settings can block internet access. Temporarily disable them to see if the issue persists.

    If these steps do not resolve the issue, you may want to consider reaching out to Microsoft support or checking community forums for further assistance specific to your build and the connectivity problem you are experiencing.

    Hi ChrisP_SD,

    Thanks for reaching out. I'm here to help!

    Since the issue persist after performing the troubleshooting steps. you may consider rolling back the 25H2 update temporarily until Microsoft releases a fix. You can do this via Settings > Windows Update > Update History > Uninstall Updates.

    I recommend checking the related thread on Microsoft’s support forums: https://v4.hkg1.meaqua.org/en-us/answers/questions/5594144/wi-fi-keeps-cutting-out-after-update-to-25h2

    Hi Carlo,

    Thanks for your support with this. After digging for several weeks for an answer, it turns out this does not appear to be a Windows bug. I discovered a free app called MyPublicWifi was binding thousands of TLS sockets over the course of the day and rendering my internet connection useless. This was happening on all my computers that were running Windows 11, but wasn't a fault of Windows 11. The solution was simply to remove this program and then everything went back to normal.

    Thanks again,

    Chris
