iPhone SE 2020 WiFi Issues

There is an old thread for this (discussions.apple.com/thread/251386939) but the last reply was July 2021 and it does not appear that this was ever resolved and you can no longer reply to it. My SE works fine with my router however I just added an outdoor long range AP to my network that uses my main router. Any Androids or other iPhones can access the internet on the AP. However, my SE connects to the AP's SSID but cannot access the internet. Tried all of the suggestions in the original thread.

Any ideas?

Thanks----
