Title:
  Atheros wireless AR9462 keeps disconnecting

Status in linux package in Ubuntu:
  Expired

Bug description:
  Identical experience to the description in
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1361646 with the
  AR9285 although with a slightly different card.

  My impression is that the disconnects started with this upgrade,
  although it could have been slightly earlier due to the holidays:
