Yeah, same here. I've tried the default username: admin, password: password and my xFinity user/password and my router user/password. Nothing works. Hope you get an answer.
Are you using a computer to log in?
Hello Ech0z. We appreciate you visiting and posting on the Xfinity Forums. Have you tried factory resetting the gateway?
This doesn't reset the admin gateway login. I cannot access it and have reset 4x.
Are you saying a System Reset doesn't change the default signon/password?
