Title:
  168c:002b Atheros AR9285 wireless connection unstable

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  I currently am experiencing issues with the "ath9k" modules present in
  kernel "2.6.31-20-generic" on Kubuntu 9.10. when using the stock
  modules included with that kernel my wifeless connection in extremely
  unstable and disconnects and reconnects frequently. After i installed
  "linux-backports-modules-wireless-karmic-generic" i have been able to
  maintain a wireless connection but am suffering from serious speed
  issues. the speed will drastically spike up and then slow down to
  taking several minutes to transfer even one MB between the laptop with
  the Atheros and a desktop wired directly into the router. we have
  other laptops and various other devices that are able to use the
  wireless with no issues. it seems to only be this machine with the
  AR9285.
