Hi:

I am using @home service right now and rent their RCA cable modem.  I wonder if it will be worth while to buy a cable modem myself.  But I don't know what kind of cable modems are compatible with @Home service.  And in case I move next year to some area with some other cable modem provider, will it be compatible.  Any suggestions?

Any cable modem should be compatible unless one of two instances occur


1. A specific model modem has had problems with the internet service providers software

2. The connection on the back is proprietary (meaning like a hybrid connector designed only to connect to one type).

Here is an exerpt from http://www.roadrunner.com 
it is a cable service provided by time warner communications

How does Road Runner connect to a computer?

The Internet signal, carried over the cable line coming into your home, is routed through a cable modem, then to the computer through 10BaseT Ethernet connection or USB port (available with Windows 98 and Windows ME only). If the computer does not have a Road Runner 10BaseT Ethernet port, one can be installed as part of the standard Road Runner installation.


You would have to have a NIC card in your PC that takes standard 10baseT Ethernet connection (RJ45)cable to connect modem to pc

it connects like this:
cable line to cable modem to ethernet card in PC

Since you are already using a cable modem look at the back of it there should be a wire running from it to your pc this wire should be like putting two standard phone line cords together side by side and a little thicker then a regular telephone line cord.


The only drawback is if you do buy this modem and then try to set it up the service may or may not help you if you use your own modem they most likely will tell you to contact the manufacturer of the modem to set it up properly this can be easy or become a total headache depending upon modem, your pc knowledge, how good the tech support is and the lasty but most important Software conflicts.

There software may not work properly with the modem you get if the modem and the software have known conflicts or do conflict.

The best way to sidestep the whole conflict is to call the Internet Service Provider and ask them which modems they have problems with. Then write them down and stay away from them.
