I already tried so many solutions but nothing works for me , I'm looking for answer from so many days. Please Someone solve my issue . If anyone want any other information please let me know.
Any help would be greatly appreciated.
sudo iw dev
. If iw is not installed, install it (sudo apt install iw
)sudo ip l s wlp6s0 up
and shows us yoursudo iw dev
stdout after that. what is strnage is this "dell wireless" interface... wtf is that? to be sure that it is not bllocking somehow your qualcom. you have on this interface a soft block (dosudo rfkill unblock wifi
) and a hard block (check efi-bios and button)
