This Unifi controller Adopt procedure works at least for:
- AP-AC v2
- AP AC Pro
- Unifi server: 192.168.1.2
- New Unifi WiFi AP: 192.168.1.23
- Connect the POE port of Ubiquiti power supply to Main of the Unifi AP, and LAN to your switch, then power up.
- Find the IP address of the new Unifi AP, assuming there is a DHCP server. Many people assign static IPs (via the DHCP server) to WiFi APs in general for convenience:
nmap 192.168.1.* -p 22 --open
In a few seconds you’ll get a list of devices–one of them will be the new Unifi AP.
- SSH to the AP. login/password:
- Tell the AP to look for the local Unifi server:
infoand you should have
Status: Not Adopted

- If not, look to Troubleshooting section below.
- Click the new AP and click the little add/adopt button.
- You should see status “adopting” and then a minute or two later “connected” for this new AP.
Consider optimizing your Unifi WiFi coverage & performance via channel, SSID, power best practices.
For problems adopting the new AP, SSH into the AP and type:

Try taking out the hostname for this device in your DNS server, especially if other devices on that net can’t resolve it.
Be sure your AP can communicate over TCP 8080 and UDP 3478 with the Unifi controller.
