I found this solution from the italian ubuntuforums; I translate it to you:

open the file /etc/modprobe.d/blacklist.conf executing the command:

sudo gedit /etc/modprobe.d/blacklist.conf

Check if you find:

#blacklist acer_wmi

and erase the number sign. If you can't find it, please add at the end:

blacklist acer_wmi

(obviously without the number sign)

save and reboot.

Then execute:

sudo rfkill list
