I'm not sure if this would apply to you or not...When I was at school in NY, I was using RR. About two years ago, they took out the need for software (RR manager or whatever it was called), although the install techs still use it (why I have no idea, but I would guess it makes registering your account easier). To set up your cable modem you need only to (in X) open up the network panel select built in ethernet, use TCP/IP and configure using DHCP.

If I am misunderstanding the "configured in 9" part, let me know, and I will help you further
