It's a fresh Install. There is no Hardware Switch to Turn it On or Off. It was working before on 16.04. Had to reinstall due to F***up dpkg and now it's not working. Tried everything from the net, loading firmware from official intel linux. still no way out.

$ rfkill list all

Run in a terminal

sudo tee /etc/modprobe.d/blacklist-acer.conf <<< "blacklist acer_wmi"

and reboot. This will remove the block.
