Wireless Region Linux

Settings Wireless Region Linux – Channel 13 Backtrack 4

By | Linux, Sample Work | No Comments

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 :

[raw]iwconfig wlan0 channel 13[/raw]

And commonly you will get

[raw]error for wireless regquest ”set frequency”
(8b04)
set failed on device wlan0 ; invalid arugment[/raw]

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

[raw]iw reg set FR[/raw] [raw]iw reg set US[/raw]
