I ran a cable out the side of the house and they connected to it. Never came in the house. Even gave me the cable.  I am using a Motorola SB6121 that I purchase and connected to single computer, Ubuntu 12.04, !G lan rate I am getting 25D/4U rates. This is (supposedly) the lowest internet rate - 24.95/month  for 6 months and 49.95/month after that. I have no other Comcast services.

I can even pull the LAN lines and I still see this constant data. I don't think I can http to the modem config page in this configuration.I would need to connect the computer directly to the modem.

It is the way cable works! You are seeing your neighbors traffic go by. Cable
is a shared connection unlike DSL or FiOS. All of the traffic in your node goes
through the same cable. That makes a really good argument for encrypting all
traffic.

HTH.
