Important Notice:
We've updated the UniFi Network controller to improve security. Starting with UniFi Network version 5.10, the required minimum firmware for UAP/USW will be 4.0.9 and for USG will be 4.4.34. Devices on earlier firmware will show in the controller and work as you've configured them, this update doesn't change any of the settings. However, please note you will not be able to modify the device configuration until you update the firmware.

This update contains an upgrade to the overall security of the UniFi platform and its devices, it is highly recommend that everyone upgrades to this version. We will also be preparing 5.6.41 to accommodate 1st gen AC devices.

We want our users to have time for adoption and migration to this version, all feedback is welcome.

  • 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). It's worth noting that maximum throughput will be affected when using 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 in the US. 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).
  • As of 5.7.x+ we only support Java 8. At this time Java 9+ is not supported.
  • 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.
  • New Cloud Access requires outbound 8883/tcp to be open/unrestricted.
  • Linux systems must be running a version of MongoDB prior to 3.6.x. We recommend 3.4.x. This is most likely to be an issue on Ubuntu 18.04 LTS, as it currently offers MongoDB 3.6.x+.
  • The proper keystore alias and name are unifi. If your custom SSL cert is no longer working, please verify that you are using the proper keystore and alias. A bug previously allowed ubnt to work, although that was never technically correct. If you find mention of these invalid steps on the community, please point them out so we can fix them.
  • The initial database migration will take longer than normal. It is expected to see mongo using most, if not all, of the available CPU cycles during this process. Please be patient, this process could easily take 15+ minutes, depending on the amount of historical stats, as well as the system specs. As always, err on the side of caution, and make a backup before upgrading.
  • The controller will not start if it is set to bind to a privileged port (<1024), as it now runs as a non-root user.
  • If your controller is running on a UniFi Cloud Key (UCK), make sure it is on firmware 0.6.4 or later, otherwise the controller will not start. This firmware is available via the normal upgrade mechanism found in the controller or it's local management page. Make sure to make a backup before upgrading the UCK firmware, as you'll need it to restore after, and it's good to have a backup on hand before any controller upgrade.
  • Support for PicoM2 and 1st gen AC models was dropped in 5.7.x. Please see our announcement HERE.
  • As of release branch 5.7.x we've made some important changes to the Wireless Uplink feature (feature details HERE).
    • We removed the "Enable automatic uplink failover" from wireless uplinks as it is no longer needed.
    • We added the ability to opt an AP in or out of wireless uplinking to another AP. This is done by checking the "Allow meshing to another access point" option found under device properties>Config>Wireless Uplink.
      • This option should be disabled on wired APs, but is required to be enabled on wireless APs.
      • If you disable this option on a downlink/wireless AP, then your AP will be disconnected from the network and require further action (including physical access).
      • If upgrading from 5.6>5.7 then this already be disabled on wired APs, but if upgrading from an earlier 5.7. release then this may be enabled on wired APs.
      • Again, this option should be enabled on downlink/wireless UAPs only. It should not be enabled on wired UAPs.
    • We added the ability to set uplink priorties. This allows you to define the preferred uplinks for a downlink/wireless AP.
  • Fixed IPs (DHCP reservations) are now required to use unique IPs. The same IP cannot be assigned to more than one device. For configurations that already contain duplicates, only the most recently active device will have its fixed IP provisioned to USG. The controller's server.log will contain a log message skip provisioning duplicate fixed IP <IP address> for user[<MAC address>] indicating which was omitted where there are conflicts.

Possible Upgrade Paths:
  • The following listed versions are the latest version you can upgrade directly from for recent release branchs: 5.10.14, 5.9.33, 5.8.30, 5.7.28, 5.6.40.
    • As long as you are on that release, or an earlier release within each branch, then you can (directly) upgrade to this release. The earliest release you can directly upgrade from is 3.1.0. If your controller is version starts with 2.x or 1.x, then you will need to upgrade to 3.x before you can upgrade to this release.
    • The release branch is determined by the first 2 numbers (so 5.10, 5.9, 5.8, etc). The last number determines the version (within that branch). A newer release is indicated by a higher number, and an earlier release is indicated by a lower number. All release branches start at .0 (e.g. 5.10.0, 5.9.0, etc.).
    • If you're on a newer release than what is mentioned, then you'll have to wait until this release is updated so that it supports upgrading from the release you're running now.

Known Issues:
  • Some statistics on the dashboard are still under development. Please share any and all feedback!
  • If the web interface doesn't seem to be displayed/drawn properly, then you likely are hitting a browser caching issue. Please force a hard refresh, and that will clear up any caching issues. Thanks!

Controller bugfixes/changes since 5.10.12:
  • Fixed an issue that could prevent database migration from succeeding when upgrading from a previous version.
  • Fixed issue where setting SSH username and password on a UCK would fail and not notify the user.
  • Fixed issue when clicking Submit button for changing SSH credentials.
