You may first want to check the router if these two APs have a valid IP address. If yes, try pinging to these IP addresses from a laptop connected to the router.
After that you can try entering the APs IP address in a browser in this format - https://ipaddressofap
Try logging in with admin/admin or super/sp-admin credentials. If you are able to access the Web page, you can configure the SSID again. If you run into any issues, please let me know.
