Rebuild all dkms and kmod drivers, specifically your wireless driver. iferror, reinstall your kernel and firmware (if using firmware) again and allow mkinitcpio to finish and update grub/systemd-boot entries.

Use this community for anything related to linux for now, if it gets too huge maybe there will be some sort of meme/gaming/shitpost spinoff. Currently though… go nuts

Alright I solved it by just chrooting in again and deleted and reinstalled linux-firmware.
