Settings Wireless Region Linux – Channel 13 Backtrack 4

One of the most recent problems I stumbled upon while running Backtrack, or any other linux distro for that matter is setting the region on a wireless card.  The typical procedure is :

1
iwconfig wlan0 channel 13

And commonly you will get

1
2
3
error for wireless regquest ''set frequency''
(8b04)
set failed on device wlan0 ; invalid arugment

There is an easy fix for this that will allow you to change the region mode your wireless adapter is in.

1
iw reg set FR
1
iw reg set US
