Connect the AP
Plug the UniFi AP into your network (PoE switch or PoE injector).
Make sure it gets power and an IP address from your DHCP server (usually your UniFi Gateway or router).
Log in to UniFi Dashboard
Go to your UniFi Controller / UniFi OS Console (Cloud Key, UDM/UDR, or UniFi Network Application).
Open the UniFi Network application.
Go to Devices
In the left sidebar, click Devices.
You should see the new AP listed as Pending Adoption (or “Ready to Adopt”).
Adopt the AP
Click on the AP.
Press the Adopt button.
The controller will push your settings (SSID, VLAN, etc.) to the AP.
Wait for Provisioning
Status will change from Adopting → Provisioning → Connected.
Once “Connected,” your AP is fully added.
Make sure the AP is on the same Layer 2 network as the controller.
If it shows as Managed by Other, reset the AP:
Hold the reset button (small hole) for ~10 seconds until LED flashes.
Then try adopting again.
Ensure ports (especially 8080/8443/3478) are not blocked if controller is remote.
