Hi all,


We've prepared firmware One really important point about this firmware is that there is downgrade protection for UAP-AC-HD/SHD (only). Once on 3.9.1, they will not be able to downgrade to earlier releases. You'll also notice that 1st gen AC firmware is no longer present. That's because they've moved to LTS support only. For more information on that, please see HERE.

This assumes your device(s) are currently running at least 3.7.51, 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.
