Change TX Power in BackTrack 5 R2 | DishingTech Edition

A higher dbm value with your card should result in faster and higher percentage of successful results.

You can change the tx power using the following commands.

sudo iwconfig (find out where your card is, in this case wlan1)

iw reg set BO

iwconfig wlan1 txpower 30dbm

This card is rated more than 30dbm!

Now it is :)

If you get the following error code:

Error for wireless request "Set Tx Power" (8B26) :
SET failed on device wlan1 ; Invalid argument.

Make sure you update BackTrack and compat-wireless

takka360 on Ubuntu Forums stated a workaround where you can find a Bolivia (BO) proxy from Hidemyass using the Firefox browser. Disconnect from WICD. Then go to edit preferences > advanced > network > settings and manual proxy. Also add the required port number. Now go to WICD and connect using the new proxy.

Check out CRDA and other regulatory domain codes (Country List). New Zealand (NZ) and are few others are also rated @ 30dbm.
