Zwiększenie mocy karty WLAN - Intel Centrino Wireless-N 2230
 
Witam, chciałbym zwiększyć nieco moc swojej zintegrowanej karty WLAN - Intel Centrino Wireless-N 2230

Obecnie karta pracuje na 39mW.

Cytat:

andy@nabuchodonozor:~$ iwlist wlan0 txpower
wlan0 unknown transmit-power information.

Current Tx-Power=16 dBm (39 mW)

andy@nabuchodonozor:~$ sudo iwconfig wlan0 txpower 17
Error for wireless request "Set Tx Power" (8B26) :
SET failed on device wlan0 ; Invalid argument.
andy@nabuchodonozor:~$ sudo iwconfig wlan0 txpower 50mW
Error for wireless request "Set Tx Power" (8B26) :
SET failed on device wlan0 ; Invalid argument.
Czy to oznacza, że robię coś źle, czy karta po prostu tego nie obsługuje?(Tego nigdzie nie znalazłem).

Sterownik karty to iwlwfi
