Title:
  Atheros AR242x/AR542x wifi reports "device not ready" after suspend /
  resume

Status in “network-manager” package in Ubuntu:
  New

Bug description:
  After first boot, the wireless on my Fujitsu Lifebook P1510 functions
  well.

  However, after suspending, the wireless adapter never comes back into
  operation, with nm-applet reporting "device not ready". There seems to
  be no option but a complete reboot. After a reboot it's back in
  operation again.

  Should I consider reloading some kind of kernel module to bring the
  wireless back up, if so, how can I automate this, and should this be
  triggered by the network manager itself on resume?
