In the wireless penetration tester, ALFA AWUS036H is one of my favorite devices. It’s because the device support packet injection. Beside that, the device has an amazing Tx-Power 30 dBm = 1000mW = 1 W. For better performance during the penetration testing, I usually set the Tx-Power to the maximum (30 dBm) in the BackTrack 5 R3.
Before that, let’s check the default dBm the ALFA AWUS 036H in BackTrack 5 R3 :
default dBm ALFA AWUS 036H in BackTrack 5 R3
From the picture above indicate that the default dBm of ALFA AWUS 036H in BackTrack 5 R3 is 20 dBm.
OK, let’s set the Tx-Power of ALFA AWUS036H to the max ( 30 dBm) :
- Shutting down the wireless interface : ifconfig wlan0 down
- Set the regional device to BO ( Bolivia ) which is allowed we set Tx-Power to 30 dBm : iw reg set BO
- Set the Tx-Power to 30 dBm : iwconfig wlan0 txpower 30
Now, the txpower ALFA AWUS 036H is 30 dBm
I hope this is useful for you 🙂 . If you need to buy the ALFA AWUS 036H , please contact me by mention me in the twitter

Error for wireless request “Set Tx Power” (8B26) :
SET failed on device wlan0 ; invalid argument.
I have install bt5 r3, apt-get update/upgrade, connect alfa awus036h and i get this error. wifi card work at 20db. why??????
Please help me!!
Sometimes if your built-in wifi comes up wlan0 and usb 036h comes up wlan1 change command accordingly.
ifconfig wlan0 down
ifconfig wlan1 down
Be sure to reg set for your country
iw reg set US
reg set for US is 27 dbm maximum
iwconfig wlan1 txpower 27
I have noticed if you autoremove network manager and install wicd on Kali or BT there will be no issues.
# apt-get remove –yes network-manager
# dpkg –purge network-manager-pptp-gnome network-manager-pptp network-manager
# apt-get install wicd
thank QQQQQQ very much for this post 😉 helpfull.
