    How do i set the netwok adapter power to maximum?

    In windows, this can be easily set under device manager --> hardware --> ..power management...

    I believe they are set to maximum by default. You can experiment. Here are my abbreviated tests:
    chili@LAPTOP40:~$ iwconfig eth1
    eth1 IEEE 802.11abg ESSID:"GBR1"
    --- snip ---
    Tx-Power=20 dBm
    --- snip ---
    chili@LAPTOP40:~$ sudo iwconfig eth1 txpower 18
    [sudo] password for chili:
    chili@LAPTOP40:~$ iwconfig eth1
    eth1 IEEE 802.11abg ESSID:"GBR1"
    --- snip ---
    Tx-Power=18 dBm Sensitivity=8/0
    --- snip ---
    chili@LAPTOP40:~$ sudo iwconfig eth1 txpower 21
    Error for wireless request "Set Tx Power" (8B26) :
    SET failed on device eth1 ; Invalid argument.
    If you find that the power is not at maximum, you can add a line to /etc/rc.local above 'exit 0':
    Code:
    iwconfig eth1 txpower 20
    I am not at all certain that all cards allow the power to be changed.

    It is indeed set at maximum by default.
