restart wlan9

[tobias.e]

actually, the chage can only be made for wlan0: 

Code:

root@openplotter:~# iwconfig wlan0 power off
root@openplotter:~# iwconfig wlan9 power off
Error for wireless request "Set Power Management" (8B2C) :
   SET failed on device wlan9 ; Invalid argument.

Maybe, the problem was, that wlan0 is idle and "real" device goes into powersave, and the "virtual" device wlan9 doesn't like that ;-)
