Had the same issue back in the time i was in unbunun.
I was able to fix that… as far as i remember but how … i don’t remember

share output of the following commands

rfkill list all
rfkill ublock all
lspci -nn | grep 0280
ifconfig

exact terminal outputs please

reinstall the drivers… share each and every possible output… can’t play guessing game… share output we might debug it together
