Travelling transatlantic tomorrow (yippee!!), and one issue I needed to address is how to turn off my wireless card for the flight (to save battery life and/or stop the plane crashing.. you decide which;)
Here's how it's done -
Turn the thing off -
~$ sudo iwconfig wlan0 txpower off
And back on again-
~$ sudo iwconfig wlan0 txpower on
simple!
BTW - bluetooth services are disabled on this laptop... I have no need for it.
