Situation: The client purchased two TP-link wireless APs and tries to configure them as Wireless Controller. He can see the Wireless APs but they are pending.
Troubleshooting: By design, TP-Link controller uses default username and password admin to add each AP. If you have changed the default admin password, it will show pending. You need to click on Pending to abode it, which will popup for the admin password you changed. If you don’t enter correct password or don’t remember the password, you need to reset the Wireless AP.
