I have seen a few threads with mon0 as the interface for this card after
airmon-ng start wlan0
But i only get this after it,

root@bt:~# iwconfig
lo no wireless extensions.

eth0 no wireless extensions.

wlan0 802.11b/g Mode:Monitor Channel=12 Bit Rate=11 Mb/s
Tx-Power=5 dBm
Retry on Fragment thr off
Link Quality=31/100 Signal level=21 dBm Noise level=-187 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0

Also why is this only 5dbm shouldnt it be like 25 or something?
