I have a Senao 2511 CD PLUS EXT2 with a 5 dBi Omni RP-TNC antenna running in 
Master mode.  iwconfig shown below.

I still don't seem to get good range.  It seems the same as any other card 
I've used.
How do I check if the card is really transmitting at 200mW ?
If it isn't, then how do I set the txpower?

iwconfig won't set it with iwconfig wlan0 txpower 200mW:
Error for wireless request "Set Tx Power" (8B26) :
    SET failed on device wlan0 ; Operation not supported.

gct3102:/etc/rc2.d# iwconfig wlan0

Thanks in advance,
