Comment 55 for bug 53310

PJ: yes, it is still P157 (it is great I can run modern Ubuntu on almost 5 year old notebook more or less without a glitch).

The code you posted assigns /sys/devices/pci0000:00/0000:00:1e.0/0000:02:06.0/rf_kill to $KILL,
when I do echo 1 > $KILL (under root permissions) I lose the signal in less than a second. I can get it back with echo 0 > $KILL - that is the same as on your side. So the ipw2200 has some control over the kill switch.
