[SOLVED] unable to scan for or connect to wifi networks

esskayesss · 2023-05-10 21:37:49

the wifi receiver was all fine and working on KDE, but with this fresh install, there are issues randomly. the wifi worked earlier and until suddenly i wasn't even able to bring the interface up. i then installed the relevant driver from https://aur.archlinux.org/packages/rtw88-dkms-git, but again as you can probably notice, this package doesn't enjoy great reviews in the comments. i'm kinda lost but i believe there must be some firmware or configuration missing. i've tried my bit and i'm stuck.

relevant dmesg logs:

EDIT: for the moment, i tried uninstalling the rtw88-dkms-git package and the interface seems to work. i will mark this thread as solved for now but i know it will cause hiccups again.
