[Bug 1258675] Re: hardware switch of wireless not working for Centrino Advanced-N 6235

 

Just logged out, with WiFi turned ON, and the WiFi button worked, but
still didn't change color.

WORKAROUND:  If  you have turned WiFi off via the network widget, turn
it back on, then ONLY use the WiFi button to turn WiFi on/off.  It will
work both when you are logged in, and when you are not.  It still won't
change color though.

Title:
  hardware switch of wireless not working for Centrino Advanced-N 6235

Status in The Linux Kernel:
  New
Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I have ubuntu 13.10  64-bit running on a HP ZBook 15. The notebook uses an Intel Corporation Centrino Advanced-N 6235 (rev 24) wireless adapter.
   
  The wireless networking principally works. The issue is that it is not possible to enable or disable it using the hardware button. The only way is the software control (clicking on "Enable Wi-Fi").

  BTW, when I click on "Enable Wi-Fi", it indicates the changes status
  of the wifi radio by changing the colour of the light on the hardware
  button. (This is the correct and expected behaviour. What is wrong is
  that I can not change the status by pressing the hardware button.)
