Resolutions attempted:
- Downloading official iwlwifi drivers from Intel, Dell and my /lib/firmware
folder (-34.ucode from Intel and Dell and also the -33, -34, -38, -41, -43 and
-46.ucode from /lib/firmware)
- Downloading the backport iwlwifi drivers from PPA
Research: My suspicion is that there might be a conflict with the
Bluetooth module (hindering the correct firmware from being loaded) as
there was a time the wifi briefly worked then stopped when I turned
off Bluetooth. However, now I can't turn off Bluetooth and wifi. As
you can see, the radio kill button has just the Bluetooth option which
doesn't even work.
Please help me?
