    I have tried both option's but i still recieve the same error,

    Is this maybe cause my wifi card can't support 20 + DPM?

    I tried change it below 20 and it worked but if i try to set it 21 or higher i recieve the same error,

    I guess this doesn't increase the "Receiving" sensitivity of your device.

    It seems to me I've found the solution.

    You should do 'ifconfig <device> down' for all the wireless devices!
    After all the wireless devices were down, you can make 'iw reg set BO' successfully! And 'iwconfig <scan_device> txpower 30' .

    WE have run six AWUSO36H wifi recievers at 30 dBm constantly for over two years and have never had any problems. One country we ran it outside when free air temperatures were 48 degress C in the shade for months.

    Hello,
    If I follow these instructions for my Alfa AWUS036H happily shows the Tx Power increased up to 30.

    The problem is, that it looks like the card stops working afterwards. a
    airodump-ng doesn't catch any packet on any channel until I switch the country code back to the original '00'.
    Any clues?
    Thank you very much!
