Whether they control software or firmware to tell the radio to turn off,
its exploitable. Maybe the more important question is "does the light
that says my Wi-Fi radio is off mean a damn thing?"

One would assume that when you turn it off, and the light goes off, that
the LED is told to be on or off at the same time the command is
processed to turn the radio on or off. But as with anything with
computers, there is some way around it. Do I know? No. But I do know
that whether it is through the way the command is processed or maybe a
rogue driver, someone will find a way to turn the radio on and keep the
light off.

Ive been asking the same question for quite some time now. I own an acer
laptop with atheros based mini-pci wlan card. When I press my wlan
poweroff-button on Ubuntu the only thing that happens is that no more
wlans are detected in range, but iwconfig/ifconfig detects the hardware
as if I did nothing....dmesg says sth about some unrecognised key
pressed but thats all. I wonder how the switch interacts with my
hardware....On windows xp (with official drivers) the card is disabled
in device-manager when i press the button but not deactivated entirely...
