[Michael Heuberger <michael.heuberger@xxxxxxxxxxxxxxxxx>]

Public bug reported:

```
$ sudo iwconfig wlan0 power off
Error for wireless request "Set Power Management" (8B2C) :
    SET failed on device wlan0 ; Operation not supported.
```

No idea why. It should work and I have wlan0 listed here:

```
$ sudo iwconfig
[sudo] password for michael-heuberger: 
eth0      no wireless extensions.

wlan0     IEEE 802.11bgn  ESSID:off/any  
          Mode:Managed  Access Point: Not-Associated   Tx-Power=off   
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off
          
lo        no wireless extensions.
```

Any clues? Or is this a bug? Thanks for helping!
