I just set up a new account at a new address. Everything was working perfectly for a few days with the black gateway i got at the xfinity store. I switched the gateway to the new one i got in the mail, which is the new generation white one. Now the WiFi doesn't work. Whatever device tries to connect to it is disconnected after a few seconds.

What is going on?
