TitleWireless G clients keep disconnecting from AP after firmware upgrade
Symptoms
Linksys WMP54GS PCI adapters for desktops cannot connect to the Wireless Network after the 9.21.15 upgrade.
Environment
  • ExtremeWireless appliances
  • AP3705, AP3710, AP3825
  • firmware 9.21.15, 9.21.16, 10.21.02, and 10.21.03
Cause
  • Certain end devices will fail to connect (or remain connected) when they send power save poll packets. The Access Point was using code created prior to 802.11n updated queue and poll handling processes, and the Access Point firmware needed to be updated.
  • Also, in the 9.21.15, 9.21.16, 10.21.02, and 10.21.03, the Rx path was no restarted after the Tx queue flushing mechanism was completed, placing the radio in a stuck state.
Resolution
The full fix and resolution will be available in the next 9.21.xx and 10.21.xx Maintenance Releases.
