Setting up a Ubiquiti Cloud Gateway Ultra begins with the UniFi app on your phone and an account, and the gateway takes you through the set-up steps without you needing to enter its address. Plug the gateway's WAN port, usually the one marked Internet, into your modem or ONT and give it power, either from the adapter or through Power over Ethernet. Open the UniFi app, sign in with your Ubiquiti account and choose to add a device;
The checks in more detail
the app finds the gateway over Bluetooth or the network and asks you to name your network and set a Wi-Fi password if the gateway has Wi-Fi, which the Ultra does not, so you will add an access point separately. The set-up applies firmware updates, so allow it a few minutes. Choose your internet type. Most cable and fiber connections use DHCP and need nothing else; a DSL or some fiber lines need PPPoE with a username and password from your provider, and some need a VLAN tag, which you set under Internet in the settings.
If your provider limits the router by the address of the old equipment, you may need to power the modem off for a minute after connecting the gateway. Connect your access points and switches to the gateway's LAN ports and adopt them in the application. The gateway does not broadcast Wi-Fi on its own, so a UniFi access point or another one in access point mode is needed. After set-up, check the firmware in the application, set a strong admin password and turn on two-factor sign-in.
Turn on the features you want in stages, since each one uses part of the gateway's capacity. Back up the configuration from the settings. If the gateway does not appear in the app, restart it, check the cable, and make sure your phone is on the same network. If a previous gateway was set up, use the reset button as the guide says and set it up anew. Contact Ubiquiti if the gateway cannot be adopted after a reset.
