Yesterday, my boss asked me if I could install ubuntu gutsy on his old unika laptop. Almost everything went fine, but the wifi. Even the kill switch wasn’t working and, typing in a terminal:
always outputs “radio: off”. I had also in dmesg this error:
ipw2200: failed to send TX_POWER command
So, the base of the problem was to have a working kill switch button. Here what I did:
sudo modprobe rfkill sudo modprobe rfkill_input
then I hit the killswitch button and, yay ! it worked.
To make this permanent I had to put these lines into /etc/modules :
and to have the led working, I created a file in /etc/modprobe.d called ipw2200 where I put this line:
et voila 🙂
The only annoying thing left is that the wifi is always desactivated at boot.
