Since a while back, I've had issues with my wifi. It started a month ago when I was using ubuntu 20.04. I've updated to ubuntu 21.10 since but the issue remains. The problem is that the wifi abruptly turns off after a while (sometimes a few seconds after booting, sometimes a few hours) and that it disappears from the menu and display wifi adapter not found in the settings. I know this is a common issue but I haven't been able to solve it.

Update:

I'm using an intel open-source driver that is supposed to work. I've tried disabling secure boot in the BIOS, updating the BIOS to the latest version. I've also tried disabling wifi power management. Nothing works. Although it feels as if the wifi-dissapears less frequently there are still issues.

Thank you in advance! :)

I ran into a similar issue years ago, and it turned out to be a bugged power saving mode.

In /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf, change wifi.powersave = 3 to wifi.powersave = 2 to disable it and see if that fixes your problem.
