I got a new pc and it has a mediatek wifi I tried every kernel from 5.12 to 5.16, nothing worked. BT works for some reason, it seems to be a driver problem not loading (checked everywhere, people made it work somehow) The card works in windows, I'm NOT dual booting, just installed to check.
these are some info:

Although a long time user, not really that savvy on this. Never had hardware problems. I got a fresh kubuntu install
any idea? (using usb tethering on mobile)
