Realtek Rtl8191se Wireless Lan 802.11 N Driver For Windows 7
Eui Grey
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.
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:

@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.
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.
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.
