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 (seeHERE). Please note that DPI will not work when using QoS, as traffic will not be offloaded. It's also 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 fromHEREandHERE(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.
The initial database migrationwill 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.
Manual site-to-site VPN status is not reflected on the UniFi dashboard widget. Currently it will look like it's offline, even when the tunnel is up.
Controller bugfixes/changes from 5.5.20:
Fix for wrong data in VLAN column in WLAN list.
Revert "change auto VPN VTI subnet mask to /30" as it needs to be reworked.
Change auto VPN VTI subnet mask to /30.
Display WLANs table in Property Panel for In-Wall.
Fix an issue preventing switch ports from coming up after being disabled.
Fix a bug with IW causing the port to be disabled when the VLAN is off (reportedHERE).
Fix a backend bug with guest access.
MAC address input validation improvements.
Fix a provisioning issue which would clear USG WAN settings.
Improvements for Ethernet bonding support on UAPs (on supported devices).
Improve topology view when using wireless uplinks.
Allow setting device credentials during setup and new site wizards.
