Comment 75 for bug 407040

@Daniel Dufour # 74

A couple of workarounds (covered elsewhere):
- Install packet called 'linux-backports-modules-wireless-luciud-generic'. It didn't completely fix the problem for me, but it happens a lot less anyway
- Instead of restarting, bring up a terminal and run the two commands:
  sudo modprobe -r ath9k
  sudo modprobe ath9k
