Admin page

Why can’t I connect to my router/modems admin page when there is an outage. I cant even see all the devices connected to my lan on the Xfinity app unless I go to security. This is very frustrating. I tried calling customer service to get a rep but the bot told me that that the outage has to be solved before it would connect me to anyone. Does anyone know how to remedy this or an isp of similar service that I could switch too. I’m am using the modem/router Xfinity provided.
