UniFi 4.7.5 is our newest official General Availability Release for UniFi wireless AP (UAP), routing (USG), switching (USW) and VoIP (UVP). It also adds support for the 2nd generation AC UAPs.


You must download and install the UniFi v4.7.5+ Controller software in order to adopt the UniFi AP AC LITE, UniFi AP AC LR, UniFi AP AC PRO or UniFi AP AC EDU.  


How to play safe?
