How do I find the WPA2 password for wifi Model EX6150

Trying to set up the device, using my Apple Airport Time Capsule. the wifi_5gext is asking for a WPA2 password. How do I find that, since I have tried the Apple id, the password for the Apple Airport Time Capsule. If I created it in the set up, where do I retrieve the password.

Hello rmillersailor

Have you tried the password of your main router?
