This page covers UniFi Cloud Gateway Ultra exactly: UniFi Cloud Gateway Ultra model UCG-Ultra; it is a wired cloud gateway and controller, not a wireless access point. No integrated Wi-Fi radio no 2.4, 5 or 6GHz client radio; the appliance manages separately adopted UniFi access points. One 2.5GbE RJ45 port, defaulted to WAN, plus four 1GbE RJ45 ports; software supports multiple WAN assignments within the documented limits. USB-C 5V DC/3A from the included 100-240V AC adapter; maximum consumption is 6.2W.

Administration uses the UniFi Network application through the UniFi mobile app or browser, with Ethernet/Bluetooth onboarding. connect the designated WAN port, sign in with the UniFi mobile app or a local browser and complete the UniFi Network console setup before adopting downstream devices. It is a UniFi Network gateway/controller for 30+ managed UniFi devices and 300+ simultaneous clients in Ubiquiti's published sizing. It adopts supported UniFi Network devices but does not itself provide Wi-Fi; preserve one clear console owner when migrating an existing site. Adoption, controller ownership and gateway role are separate from radio capability, so confirm which console owns the site before moving or resetting the unit.

For an adoption or connectivity fault, check link speed, VLAN/DHCP reachability, console ownership and the device state in UniFi Network, then use recovery mode only after normal restart and adoption steps fail. With the unit powered, hold its factory-reset button for the model-indicated LED sequence; Ubiquiti's general guidance is about 5–10 seconds, after which ownership and settings must be established again. Port roles, advanced gateway features, certifications and supplied mains plug vary by software release and sales region. Ubiquiti's live technical-specification and installation pages are the lifecycle reference; supported application versions can diverge even while hardware continues receiving security fixes. Back up the UniFi configuration before a factory reset. Match PoE, USB-C power and Ethernet accessories to the exact official electrical and link specifications; an RJ45 or USB-C connector alone does not prove compatibility.
