Title:
  [ath9k] AR5418 frequently fails to connect to WEP/WPA network

Status in The Linux Kernel:
  Fix Released
Status in Mactel Support:
  Invalid
Status in “linux” package in Ubuntu:
  Incomplete
Status in “linux” source package in Intrepid:
  Fix Released

Bug description:
  The wireless network can be seen, and occasionally connects after a
  cold boot. Most of the time network-manager complains that the WEP/WPA
  key is not correct, pops up a dialogue repeatedly.

  It may or may not obtain a DHCP lease. However, no data gets
  transmitted.

  Scenario 1: (See comment by Dennis Heinson for another scenario)
  Beta release updated 4/10/08 on a gen 2 MacBook Pro (atheros wifi) connecting to a BT home hub with WEP 64 bit encryption (configuration as shipped). No previous problems with Kubuntu 7.10 and the same hardware using self-compiled drivers.

  Linux xxxxx-01 2.6.27-4-generic #1 SMP Wed Sep 24 01:29:06 UTC 2008 x86_64 GNU/Linux
  NetworkManager 0.7.0.
  03:00.0 Network controller: Atheros Communications Inc. AR5418 802.11abgn Wireless PCI Express Adapter (rev 01)
