Im wanting to hook two computers in my house together but only on one cable modem.?

Im wanting to connect two computers in the same house, but in different rooms on the internet. One computer is on a cable modem for the net, so what exactly do I need for the other computer to run off that same modem?

You'll need a switch/ruter to plug the cable modem into and cables going into computers. You might have a need for proxy software to share connection
If you do not have multiple ethernet ports, or a wireless cablemodem, and you don't want to buy any more equipment, you can't.

But, it is possible that they gave you a USB cable modem, in which case, you could possibly split it with a USB hub.

Getting a router would be the simplest way.
A router.
check your modem first, if there is an extra port for an ethernet cable or if there are antennas. if there is an extra port just buy another ethernet cable long enough for the other PC. if you see and antenna, then purchase a USB wireless adapter for the other PC. if you dont see neither, but a router.
