Used the following script to set the TX Power.
#!/bin/bash
echo "hello, root!"
echo " taking down wlan0"
ifconfig wlan0 down
sleep 3
echo "setting Region to GY"
iw reg set GY
sleep 3
echo "setting TxPower to 30"
iwconfig wlan0 txpower 30
sleep 2
echo "starting wlan0"
ifconfig wlan0 up
echo "pulling wlan0 interface up"
iwconfig
sleep 5
echo "good bye"
I'm able to change to TX Power for my Alfa AWUS036H but not for my new AWUS036NHR v.2. Has anyone been able to change it from the default 20dBm to 30dBm?
