We had the same problem with Asus K550c on 12.04.

Creating /etc/modprobe.d/asus.conf with

---------------------------------------------------------
options asus_nb_wmi wapf=4
---------------------------------------------------------

enables WLAN fixes it.

Neither this nor blacklisting the module make the fn-f2 combination
work. The wifi LED doesn0t light up either.

Title:
  [ASUS X55C] Cannot enable wifi again using wireless hotkey

Status in “linux” package in Ubuntu:
  Fix Released
Status in “linux” source package in Precise:
  Won't Fix
Status in “linux” source package in Quantal:
  Won't Fix

Bug description:
  After using wireless hotkey to disable wireless,
  it cannot be turned on again using wireless hotkey.

  Steps:
  1. Press wireless hotkey to disable wireless
  2. Press wireless hotkey to enable wireless - but doesn't work

  Expected results: Wireless hotkey can reopen the wireless

  Actual results: The wifi is still be blocked

  When using Fn + F2 to disable wireless, rfkill shows the wireless
  network interfaces are soft blocked:

  0: phy0: Wireless LAN
        Soft blocked: yes
        Hard blocked: no
  1: asus-wlan: Wireless LAN
        Soft blocked: yes
        Hard blocked: no

  And when we press Fn + F2 again, it should show all "no" in rfkill,
  but it has a "yes" in it:

  0: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: yes
  1: asus-wlan: Wireless LAN
        Soft blocked: no
        Hard blocked: no

  So the wireless is still be blocked.
  If I remove asus_nb_wmi, the bug cannot be reproduced.
