  • As always, make a backup prior to upgrading.
  • Windows users must have x64 Java installed as we only support 64 bit webRTC library. Please see HERE and download the missing version (64bit offline Windows install package).
  • You cannot re-use a VLAN ID for dynamic VLAN if it is set as a static value for another SSID on the same AP. So, if I have a SSID set to use VLAN 10, I cannot use VLAN ID 10 for RADIUS controlled VLAN users as those users will not get an IP.
  • Smart Queue QoS is similar to the implementation as in EdgeOS (see HERE). Please note that DPI will not work when using Smart Queue QoS, as traffic will not be offloaded. It's also worth noting that maximum throughput will be affected when using Smart Queue QoS, as traffic is not offloaded. There are some rough guidelines in the article linked above.
  • DFS channels can not be used for wireless uplink as of this release. Please use non-DFS channels if you need to use wireless uplink on dual band UAPs.
  • Official UniFi MIBs can be downloaded from HERE and HERE (those are 2 different files).
  • We no longer support Java version 6, it needs to be 7 or later. We recommend Java version 8.
  • Features like airtime fairness, bandsteering, load balancing and minimum RSSI are default disabled. If you need them you need to go to Settings>Site and check Enable advanced features.
  • If you previously used Google Maps for a site map, then you have to enable this feature again by adding an API key. This is done under Settings>Controller. There is a linked guide with instructions.
  • There is a known issue with binding the SSH daemon to a specific interface. A patch was missed when upgrading dropbear. This is fixed as of 3.7.32. A later release will be posted shortly, and pushed to this controller too.


Controller Bugfixes/Changes from 5.3.9:

  • Update translations
  • Show Controller settings to super admin only
  • Improve WebSocket connection while using WebRTC
  • Fix Radius VLAN modes


Firmware Changes from 3.7.28/4.3.30:

  • [UAP] Fix memory leak when loading spectral data.
  • [UAP] Fix bug with stamgr that caused minRSSI (and possibly other functions) to not work as expected.
  • [USW] Perform ARP snooping on VLAN ARP packets.
  • [USG] Fix performance regression introduced between 4.3.15 and 4.3.16 releases.
  • [USG] Update speedtest-cli client and built-in fallback speed test server list. Fixes instances of selecting sub-optimal speed test servers leading to lower than expected results. 
  • [USG] FreeRADIUS back end enhancements for coming controller UI support.


We recommend running firmware, found in THIS post. It is also pushed to the controller.
