Title:
  Wifi/Wlan on Acer Aspire keeps switching on / off

Status in “linux” package in Ubuntu:
  Fix Released

Bug description:
  Iḿ on an Acer Aspire TimelineX 3830 TG Laptop (64bit), on which i have
  Ubuntu 12.04 Precise 64bit installed, and all works fine. Now i
  installed Ubuntu 14.04 Trusty (32bit !) as a portable OS on a USB
  Stick (LVM,encrypted) with no Problems, but it has this weird problem
  with Wifi: The Atheros Wireless Adapter, more precisely the the hard
  block option, keeps turning on and off within about 10 seconds. Tried
  loads of things concerning acer_wmi, ath9k, software/hardware
  encryption etc. to no avail. The Laptop doesnt have any hardware
  switch, only Fn+F3, which doesnt do anything (in 12.04 it works
  correctly). Bluetooth works fine.

  rfkill list gives this:

  0: acer-wireless: Wireless LAN
  	Soft blocked: no
  	Hard blocked: no
  1: acer-bluetooth: Bluetooth
  	Soft blocked: no
  	Hard blocked: no
  2: phy0: Wireless LAN
  	Soft blocked: no
  	Hard blocked: YES
  3: hci0: Bluetooth
  	Soft blocked: no
  	Hard blocked: no
   Ten seconds later:
  0: acer-wireless: Wireless LAN
  	Soft blocked: no
  	Hard blocked: no
  1: acer-bluetooth: Bluetooth
  	Soft blocked: no
  	Hard blocked: no
  2: phy0: Wireless LAN
  	Soft blocked: no
  	Hard blocked: NO
  3: hci0: Bluetooth
  	Soft blocked: no
  	Hard blocked: no

  Another 10 seconds later back to the first output. During the second
  phase i can shortly see my wifi router and others, it attempts to
  connect but never seems to accomplish before Wifi goes off again...

  It doesnt have anything to do with the router as this beheaviour stays
  when i remove my wifi from the network-manager.

  Now the interesting part: when i reboot into my well working 12.04, i get the exact same behaviour! Must be some Initialisation of the Wifi adapter that stays in the hardware on reboot. couldnt find anyone else via google with this exact issue. Help appreciated!
