We've prepared firmware 4.0.15.9872. Please see below for the changelog and links to the firmware binaries.

Firmware changes since :
  • [HD/SHD/XG/BaseStationXG] Fix some IE corruption (related to wildcard and uplink SSIDs).
  • [nanoHD/IW-HD] Tweak performance.
  • [HW] Miscellaneous bug fixes and improvements.

NOTE: You may start to see EVT_AP_RestartProc events in the controller log. If you see these, please report if there is anything specifically in your setup that triggers the events. The processes restarting is not new, but the reporting of the restarting is, and we are using these reports to clean up these issues.

SPECIAL NOTES:
  • Any US-XG-6POE upgrading from 4.0.2 or earlier will take a long time to upgrade. Don't be surprised if your switch is unavailable for 5-10+ minutes as 4.0.3+ also updates the PoE firmware to improve PD compatibility.
  • 1st gen UAPs may require extra steps when upgrading from firmware 4.0.3. You can try disabling all WLAN groups, and then running the upgrade. Devices that are seemingly "stuck" on 4.0.3 may require TFTP recovery to upgrade from that firmware.
  • Running controller 5.9.20 (or later) and not seeing the in controller upgrade? Or did you upgrade and the controller is now offering a downgrade? If so, please see my post .
