Michael Heuberger, as per your Bug Description your Power Management is
off. Hence, was it already off when you ran the command, or was it on,
you ran the command, and then it was turned off?

I also get the same message as per the Bug Description if the Power
Management is already off when I attempt to run the command.

Title:
  Unable to turn powersave for wlan0 off

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  ```
  $ 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!
