Hi,

I got a Atheros AR9285 that i can't increase tx-power level over 15 dBM.
The problem is that at such power, the connection is (very) unstable when i'm not near the AP.

when I try to increae tx-power

[root at Gauchita etc]# iwconfig wlan0 txpower 16dBM Error for wireless request "Set Tx Power" (8B26) :
    SET failed on device wlan0 ; Invalid argument.


[root at Gauchita etc]# iw reg get
