what is the default login and password for comcast xfinity smc SMCD3GNV modem?

I'm trying to access my modem's GUI through the default gateway address ( I've tried all the default login/password combos that SMC uses for it's routers and modems but, apparently Comcast changes the login/passwords for it's xfinity models. I want to access it to tweak the TCP/IP and turn on the wireless functionality. Thanks

    admin and password worked for me on a tc8305c. Other Comcast modems may use the following

    Username: cusadmin

    Password: highspeed

    Comcast has them locked down and you would need to talk to them.
