Hi @Terrasse ,
I wonder whether you could read the following post, in order to solve your problem.
‘[SOLVED] Wireless Issues / Newbie Corner / Arch Linux Forums’
I found a similar post in the forum, that could be helpful:
‘Iwlwifi not working in manjaro-kde-221115-linux519’
It has the same error code -22, which you posted as the output of sudo modprobe iwlwifi terminal command.
Hope it helps,
Regards
