I'm new here, this is my first question. Thanks all who are going to help me. I have Ubuntu 18.04 in dual boot with Windows 10.
This is the problem: I've recently changed my HP Pavilion G6 laptop wireless card (Ralink RT 5390) with an Intel (R) 7620 ac dual band wireless card.
The new wireless card worked properly on Windows, but it was "Hard-Blocked" on Ubuntu.
I tried everything, every rfkill unblock method, every modprobe thing too, but the laptop still remained in Aeroplane Mode, and I could read "use hardware switch to turn off". Obviously the keyboard key for Aeroplane Mode did absolutely nothing (neither with fn pressed nor without).
After doing all of that, I simply suspended the laptop (by closing the front lid), and reopening it WiFi magically worked. Each time I reboot the laptop I have to do this to make the WiFi work properly. Anyone knows how to resolve it?
