Why is RoadRunner so difficult to use?

Can I use Roadrunner Internet with just a Modem and Router, no Cable Box?

• I recently became a roadrunner customer and I have a question about the basic Internet service... I would like to be able to disconnect the cable box and save the $10/month (I end up with the same 15 channels either way). However, when I disconnected the box, it knocked out my internet. The modem was still connected exactly how it had been, I just removed the box, which was on a separate cable anyways, so I didn't foresee any problems. The computer was unable to pick up an IP address. Is that assigned in the cable box and then sent back to the modem? If I buy a separate router (which I have on the way) with DHCP capabilities, will that solve my problem and assign the needed IP addresses? I also have a XBox 360 and PS3 in my network, which were not picking up IP addresses from the modem either, hence the already ordered router. Any help would be appreciated. Thank you!

• Answer:

  If you broke the connection between the incoming signal and the modem, buy disconnecting the cable box, you will have to connect the two wires together where the cable box was!
