Title:
  168c:002b [asus_nb_wmi] [Asus U32U] AR9285 ath9k not working after
  updating to ubuntu 13.04 Raring (linux 3.8.0-19-generic)

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

Bug description:
  update: updated the BIOS to the latest version but the problem
  persists.

  Booting with the older kernel (latest linux kernel from 12.10) every thing works fine. After upgrading to Raring Ringtail Ubuntu 13.04, with the new kernel, hardware get blocked/disabled and wireless doesn't work:
  0: phy0: Wireless LAN
   Soft blocked: no
   Hard blocked: yes
  1: asus-wlan: Wireless LAN
   Soft blocked: no
   Hard blocked: no

  WORKAROUND - is only applicable to Asus Notebooks/netbooks that use the "asus_nb_wmi" driver:
  Create and edit asus_nb_wmi.conf file with this command:
  sudo echo "options asus_nb_wmi wapf=4" | sudo tee /etc/modprobe.d/asus_nb_wmi.conf
