After the last update for Windows 11 insider (Home). The driver for the wireless card stopped working. There is already a guide on the issue on Intel's boards, but it is not working either. So i think the issue is with the Windows.
The card: Killer(R) Wireless-AC 1550i Wireless Network Adapter (9560NGW) 160MHz
What didn't work:
Appreciate the help, thanks in advance.

@OussD I have the same problem on my Dell. WiFi is disabled after reboot. When I try to switch it on the slider jump back to the Off position. Let me know if you find a solution.

I managed to bring my Killer wireless network adapter back - after wasted a whole morning. Windows updated overnight and I lost the card after that. This was the error I saw in Event Viewer:
Killer Wireless-n/a/ac 1535 Wireless Network Adapter : The version number is incorrect for this driver.
I'm using an Alienware 13R3, updating to the latest Killer drivers didn't solve my problem. Removing it entirely (incl. the drivers) and restarting the machine magically solved it.

@OussD After a lot of research, the problem is usually solved by resetting the bios to default, mainly on dell laptops. The problem is caused after doing bios update or installing windows 11.
Also don't forget to install the updated drivers.

@ballon999 This is not working on my Surface Pro 7. I've tried uninstalling and removing the driver completely several times and each time on the restart it automatically comes back (even when I'm not connected to the internet). I had Windows 11 and reverted back to Windows 10 and still not right.

@OussD I have found this fix on Reddit and it fixed my problem. hope this works as well on you guys.
Credits to whoever that guy was. I can't find it anymore.
Edit: Step by step: First you’ll want to open up device manager, then select Network adapters. Then double click on your 1535, you might see two adapters labeled as 1535s, so when you double click make sure to read the device status text that’s show at the bottom of the double click pop up. Once you’ve located the component with the error you’ll need to click on the driver tab on the top section of the double click pop up, then click update driver, select browse my computer, then select let me pick from the list of available drivers, I chose the Microsoft drivers but either will fix the issue. Hope this helps!

I had a similar issue when I got my first wifi 6 networking card. My solution was to turn off automatic band selection in the wifi router settings. Apparently the network card couldn't handle when the band changed (something that the router did seemingly randomly), and so the network card errored out and stopped working until it was reset. However, after I turned off automatic band selection there hasn't been another issue, with that machine.
Hope it helps!

Everyone, try removing the driver then shutting down the OS, not reset/reboot. I've been fighting this for 2 days straight and even after a complete OS reinstall/downgrade from 11 to 10 the problem is still there. Immediately after the reinstall the wifi adapter worked, but after a few reboots it went back to the same issues/events in the system log. Then I tried removing the driver and shutting down completely before powering back on and the wifi is now working. For how long who knows, but give this a shot if you are struggling.

hey people, I think I fixed my issue because I haven’t had this wifi issue for a couple days now. I finally managed to replace my BIOS to the newest version and once I did I had to restart my computer after it restarted itself from the BIOS update. So two restarted, but I have been getting good wifi connection.
good luck y’all
