Sharing Internet Connection

Solution 1:

A common approach is to get a wifi or ethernet router.

Connect this device to the cable internet device, then connect your computer to the wifi/ethernet router.

Solution 2:

I recommend buying a Linksys WRT120N, this one is less than 50US$. There are other brands that are even less expensive, but I prefer Linksys.

There is one port for the connection to the cable modem, and there are 4 ports for computers (alternatively you can connect other computers via wireless)
