Hi all, 


We've prepared firmware Immediately, we've only released it for AC-HD and it has been pushed to controller 5.4.11. It will be released to for other devices at a later date. If you wish to try it on other devices now, then please see our blog post in the beta section. 


Firmware changes from 3.7.40:

  • [UAPG3] Enable DFS support for US/CA.
  • [UAPG3] Default disable 802.11w.*
  • [UAPG3] Backport offload firmware patches to improve performance.

If you have problems updating your AC-HD, or it doesn't come up after the update, then perform the following steps to resolve the issue:

  • Change both radios from auto to a fixed channel.
  • Factory default the AP (physical reset).
  • When it provisions, it will come up.
