Ubiquiti UAP-AC-LR Access Point Firmware 6.5.54

Improvements:

- Improved wireless uplink stability when the downlink's ethernet port is being used.
- [Gen4/Gen5] Improve 2.4GHz latency.
- [Gen6] Set minimum firmware version to 6.2.49 to prevent unsupported downgrades.
- [Gen6] Improved latency at range.

Bug Fixes:

- Fixed guest portal redirection not working when APs get a new IP on the guest VLAN (usually after 24 hours).
- Fixed APs occasionally picking overlapping 2.4GHz and DFS channels after an RF Scan.
- Fixed APs occasionally appearing 'Offline' in the Network Application while still serving WiFi properly, needing a power cycle to fix.
- Fixed wirelessly meshed APs (downlinks) occasionally going offline while scanning for neighbors. This was introduced in 6.5.39.
- Fixed neighbor reports not being reported to clients after 3 hours of uptime when multiple ESSIDs are configured to broadcast on an AP.
- Fixed incorrect channel change notifications being sent.
- Fixed Fast Roaming failing in some cases after being connected to the same AP for a long time.
- [Gen2] Fixed 5GHz radio not beaconing sometimes, requiring a configuration change or reboot to fix. This was introduced in 6.5.39.
- [Gen2/Gen3] Fixed client connectivity delay that occurs when clients attempt to rejoin a network after leaving it without sending a deauthentication frame.
- [Gen3] Fixed 5GHz radio occasionally getting stuck while broadcasting at 160MHz when a DFS radar is detected.
- [Gen4] Fixed clients sometimes being reported as connected even after leaving the network. This was introduced in 6.5.36.
- [Gen4] Fixed gen4 APs very rarely getting stuck on boot, needing a power cycle to recover.
- [Gen4] Fixed certain clients disconnecting when changing channel and/or bandwidth.
- [Gen4] Fixed AP getting stuck on boot intermittently.
- [Gen4] Fixed wireless downlinks going offline when channel width is changed from 80MHz to 160MHz, and then back to 80MHz.
- [Gen4] Fixed nanoHD 5GHz radio not broadcasting when set to channel 132 at 160MHz width.
- [Gen4] Fixed clients very rarely running into a state where they are connected with no internet access.
- [Gen4/Gen5] Fixed APs not broadcasting at 80MHz on channels 132-144 in UK.
- [Gen4/Gen5] Fixed kernel crashes to improve overall stability.
- [Gen4/Gen5] Fixed APs going offline after an RF Scan intermittently. This was introduced in 6.5.40.
- [Gen5] Fixed kernel crashes to improve stability.
- [Gen5] Fixed certain clients disconnecting when changing channel and/or bandwidth.
- [Gen6] Fixed management frames not using the configured minimum data rates.
- [UAP-XG/BaseStation-XG] Fixed high 5GHz radio rarely not broadcasting at 160MHz width.
- [U6-LR] Fixed low data rates being used for some 5GHz clients after switching to a DFS channel.
- [U6-LR] Fixed Intel ax200 running on a linux machine failing to roam to a U6-LR.
- [U6-LR] Fixed 5GHz radio not broadcasting after a DFS hit. This was introduced in 6.5.40.
- [U6-LR] Fixed kernel crashes to improve overall stability.
- [U6-LR] Fixed incorrect channel change alerts being sent. This was introduced in 6.5.40.
- [U6-Enterprise/U6-Enterprise-IW] Fixed incorrect channel change events being sent.
- [U6-Enterprise/U6-Enterprise-IW] Fixed incorrect 5GHz neighbor reports in some cases.
- [U6-Enterprise/U6-Enterprise-IW] Fixed empty 6GHz neighbor reports.

Known issues:

- Some Apple devices are not roaming properly with WPA3 Fast Transition/Roaming due to a bug in iOS. We are working closely with Apple to get this fixed.

About Access Point Firmware:

If you update the Access Point (AP) firmware, your device can benefit from changes that fix multiple issues encountered by wireless clients, correct different user interface problems, add various functionalities, and include support for newly developed protocols.

Before performing this task, we recommend that you read and understand all the installation steps, because there are many AP models and manufacturers available. Each producer strives to make the procedure as simple as possible, but there are cases when it's anything but that.

It is also advisable that you apply a new access point firmware in a steady power environment (UPS unit will satisfy this need), using an Ethernet cable rather than a wireless connection. The latter can be easily interrupted.

With this in mind, if you wish to apply this version, click the download button and install the package on your access point. Remember to check back with our website as often as possible so that you don't miss a single new release.
