UniFi 5.2.7 is our newest official General Availability Release for UniFi wireless AP (UAP), routing (USG), and switching (USW).
How to play safe?
Make sure you always do a backup before any updates, especially if you plan to upgrade your existing installation.
- For people who are migrating from v3, there’re many changes to APIs and it’s not backward compatible. You may need to update the shell library (unifi_sh_api) and/or your customized portal/external portal code.
- For hotspot management console, make sure you have bookmark the URL with site ID (i.e. x66cipn3, or whatever random string is generated for that site). For example:
- For Debian/Ubuntu users, please update your APT source (see HERE).
- unifi-beta/unifi-rapid are obsoleted. The old repo has been removed.
- use ‘unifi5’ in your source file, instead of ‘stable’ or ‘unifi4’
- You can no longer manage/control UniFi VoIP devices from the UniFi controller. Please use the UniFi VoIP controller for UVP products. The latest release as the time of this post is found HERE.
- You can no longer toggle the VoIP port on the USG (UGW3). It needs to be enabled prior to upgrading/using v5, otherwise you will not be able to control it. If you rely on using the VoIP port then you may want to stay on v4.8.19. Currently it can only be configured as a secondary WAN in v5, but we will be expanding the functionality so it can be used as either a secondary WAN or LAN (LAN will be fully configurable).
- 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).
- If you are coming from an earlier release, and aren’t familiar with the changes in v5, please see our initial release post HERE.
- 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.
- Cloud Access feature in this release is not supported on Linux/ARMv6 architecture (for exmaple, Raspberry Pi 1). If you have problem starting controller on this platform, please remove the native library:
sudo rm /usr/lib/unifi/lib/native/Linux/armhf/libubnt_webr
- 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.
- Do note that 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.
- It appears that VHT80 uplinks work on channel 36 and 149, but may not work with other channels selected (44, 153, 159). This bug has been present for a while. VHT20/40 and HT20/40 should work properly.
- You cannot adopt USG unless it is on a newer firmware, so it’s recommended to use the firmware bundled with this release.
- There is a known bug with RADIUS accounting in 3.7.17 on 1st gen UAPs, where it will report 4GB use upload and 4GB use download on the STOP message, regardless of actual use. This was introduced in firmware 3.7.9, and is related to the 10.2 driver merge. We will release an update in the near future to fix this. For anyone relying on RADIUS accounting, please continue to use firmware 3.7.8 or lower until further notice.
- If your USW shows as disconnected after firmware upgrade you can perform a set-inform (similar to L3 adoption, see HERE) or you can powercycle the USW. Either method should restore the device to a connected state.

****As stated in the note, this is just a change with the package dependencies, this does not change the init script. To properly define the JAVA_HOME on your Debian/Ubuntu installation you should create a default file to define the path. This method is persistent across controller upgrades. Something like the following will work (update JAVA_HOME path as needed):
echo "JAVA_HOME=/usr/lib/jvm/java-8-oracle" | sudo tee /etc/default/unifi
