    A higher dbm value with your card should result in faster and higher percentage of successful results. I will make a script soon and attach it here shortly. You will have to CHMOD permissions for your Linux distro though.
    You can change the tx power using the following commands in Terminal:
    Select All
    sudo iwconfig
    (find out where your card is, in this case wlan1)
    Select All
    iw reg set BO
    Select All
    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.

    Check out Login or Signup to view links / downloads and other regulatory domain codes (Login or Signup to view links / downloads). New Zealand (NZ) from memory and are few others are also rated @ 30dbm.
