    I believe that the cards have a firmware limitation to max rf power... I have 3 wlan adapters, one goes up to 33 dBm,oher goes at maximum 30 dBm, and the third one only goes up to 20 dBm (same computer with same regulatory files).

    ?? - TX is transmit, not RX; receive.

    Sorry to pull up an old threat but I am at a loss with this now. I have two cards, a AWUS036NEH and a TPLINK WN772N and have tried these both in VWWare fusion with Kali and Ubuntu 14.04. I am NOT trying to increase power, I am actually trying to decrease it.

    The arguments are accepted to the card but when I check the settings are not accepted. If the power levels are hardcoded to the device can someone suggest a card that will support this. If not could it be an issue that the card is managed somehwhere by the host OS and VMWare cannot change this?

    iwconfig wlan0 txpower 10
    root@kali:~# iwconfig
    wlan0 IEEE 802.11bgn ESSID:off/any
    Mode:Managed Access Point: Not-Associated Tx-Power=20 dBm
    Retry short limit:7 RTS thr:off Fragment thr:off
    Encryption key:off
    Power Management:off
