Title:
  No stable wireless connections

Status in “linux” package in Ubuntu:
  Triaged
Status in “network-manager” package in Ubuntu:
  Confirmed

Bug description:
  $ lspci | grep Wireless
  02:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01)
  $ uname -r
  2.6.32-16-generic

  My wireless connection is very unstable. Network-manager has to
  reconnect every few seconds. I tried it on a few WPA (2) networks and
  it's the same on each. I also tried 2.6.33 from Ubuntus mainline
  Kernel repository and it  had the same problems.
