[Bug 1379203] Re: [Dell Precision M2800] Wifi slider cannot turn wifi off, but works for BT

 

Wifi and Bluetooth can be controlled by the Wifi slider on 14.04.3 stock
image, however the Bluetooth indicator does not work well, it will be
grey out even you turn the slider back on (but Bluetooth still working),
and this issue could be fixed by applying updates.

  BT

Bug description:
  CID: 201404-14986 Dell Precision M2800

  The wireless slider on this system can't turn the Wifi off, but it
  could turn the BT on/off normally.

  Steps:
  1. Install 14.04.1 + update (3.13.0-37), boot to desktop
  2. Try to turn the wifi off with the slider

  Expected result:
  * Both wifi and BT could be controlled by the wifi slider.

  Actual result:
  * Only BT could be turned off with the slider.

  Wifi slider "ON"
