Important notes
  • 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.
  • 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.
  • UIS-8-450W upgrading from 4.0.33 and earlier will have their PoE firmware upgraded automatically to improve PD compatibility. That process will take a few minutes. PoE will be unavailable during the upgrade process.
  • 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.
  • All supported 1st gen APs need to be on a minimum of 4.0.10 prior to upgrading to this firmware. Controller 5.10.3+ will force an upgrade to 4.0.10 prior to upgrading to this release (only if your device isn't running 4.0.10 already).
Bugfixes
  • [nanoHD/IW-HD/UDM-B/FlexHD] Improve device boot time.
  • [UAP] Fix bug which may cause device to reboot after a provision.
  • [USW-PoE] Fix SFP TX/RX fault issue.
  • [USW-24-Pro] Fix port 6 bug which may cause traffic to stop passing in certain configurations.
  • [USW-Pro/6POE] Improve SFP port autodetect robustness.
Known issues
  • UAP, UAP-LR, UAP-IW, UAP-OD and UAP-OD5 cannot be downgraded from firmware 4.0.17+ to an earlier release.
  • UAP-FlexHD will require a custom upgrade. Support for it will be added to the firmware update service in the near future.
Instructions
Any and all feedback is welcome, including lettings us know about successful device upgrades. When reporting an issue, please ensure that you include the following information:
  • Controller version.
  • Firmware version (previous and current).
  • Device model(s).

Links are all HTTPS. This assumes your device(s) are currently running at least 3.7.56, and that the device's date is properly set (i.e. it can reach a NTP server). If you encounter issues with the upgrade, or your device isn't on a minimum supported firmware, then you can change the link to HTTP before performing the upgrade.
