Windows 11 Update Killed my WiFi - Can't get it working

adboom73 6 Reputation points

I need help. When Windows 11 updated it killed my WiFi adapter.

Windows troubleshooter was no help. I've tried to re-boot, reinstall the drivers to no avail.

Please tell me what to do to get my main laptop operational again. I can be emailed at: <Removed for Privacy>

    Hey there,

    also had his problem with the recent update on my Asus Zephyrus g15 2021

    Solution: all you have to do is, go to "device management" - "Network adapters" - search fo your WIFI module name, mine is "Intel WIFI 6 AX200" right click on it and press uninstall device. Restart your computer and WiFi should be working just fine.

    Hope it helps, good luck!

    Here is the truth of the matter..

    If you're here, one of two things has happened. The first possibility is that you just need to uninstall drivers and reboot the machine as described above.

    The second possibility is you've been fked over by Windows 11 because their developers are goofs. There are over a dozen WiFi adapter models that we've identified as being incompatible with W11. This is typically a problem in slightly older machines, but long story short - there is no resolution and there will never be one. If the basic steps do not resolve the issue, then you will need to buy a WiFi dongle and bypass the WiFi adapter that's built in.

    For the record, we've tested no external dongles that failed to work. This is limited to onboard WiFi hardware in laptops, All-in-Ones, and some desktops.

    I also am having this issue with a RAZER BLADE 15 ADVANCED MODEL 2019

    Funny thing is that it works with my phone hotspot and not my home network or any other network.

    I can use ethernet as it's no problem.

    I completely reinstalled windows a full wipe and load and it still didn't resolve the issue.

    Very disappointed
