Could you try a newer version?
(In reply to Michał Górny from comment #6) > Could you try a newer version? Of the Kernel? I am currently running 5.11.1 and it is hit-and-miss if it works. I have noticed however, that a reboot usually fixes it, if it wasn't initially working. Not poweroff and on, just plain reboot. I have tried both iwlwifi as module and built-in. If it works there are frequent disconnects, or it just shows that it is connected, but no data is really transmitted (crash log iwl_5.11.1).
