I have a Dell XPS 9550 with antergos and windows dual booted. A couple weeks ago there was some sort of fault, my laptop crashed, and antergos was gone from the windows boot menu. Using a live usb I reinstalled grub and added a new boot option for antergos in the windows boot manager. This seemed to work fine, however once booted into antergos the wifi adapter seemed to be disabled. From my digging it seems to be a firmware issue, but I cant reinstall linux-firmware. Does anyone know what’s going on?
