2. If the UniFi AP is not in the factory default state, then
click reset. Enter the SSH username and password, and
then click Apply.
3. Click manage.
4. Change the inform URL. The SSH username and
password should be ubnt/ubnt. Click Apply.
5. Open a browser to the remote UniFi Controller. The
UniFi AP should be displayed as Pending Approval.
6. Click approve. The UniFi AP will change to an Adopting
state. Eventually it will change to an Adoption Failed or
Disconnected state.
7. Perform step 3 again.
The UniFi AP is now managed by the UniFi Controller.
Once adopted, the UniFi Controller will upgrade these APs
automatically.

DNS
You have a couple of options:
DNS resolution Configure your DNS server to resolve
unifi to the IP address of the UniFi Controller.
Ensure that the UniFi AP can resolve the domain name of
the UniFi Controller. For example, if you have configured
http://<XYZ>:8080/inform, then ping the UniFi Controller
from the UniFi AP to determine if <XYZ> can be resolved
or reached.
FQDN Use FQDN for the inform URL of the UniFi
Controller: http://FQDN:8080/inform
If the UniFi AP (using a static IP address) fails to connect
to the remote UniFi Controller, then ensure that you have
properly configured the IP address of the DNS server when
you changed the UniFi AP from DHCP to static in the UniFi
Controller UI. If not properly configured, then the UniFi
AP cannot contact the DNS server to resolve the domain
name of the UniFi Controller.
If the UniFi AP has been reset to its factory defaults, then
ensure that you have informed the UniFi AP twice (using
the UniFi Discovery Utility) about the location of the UniFi
Controller.
