I can't connect with my laptop to my home wifi sometimes but it does always connect to the acces point of my phone (which is connected to the wifi that doesn't work). I tried this but nothing.

iwconfig:

lo        no wireless extensions.

enp2s0    no wireless extensions.

Bugs in MT7921 driver on 5.17 kernels. Partly fixed in 5.18, but even newest Ubuntu is still on 5.17
