If you want to share an Internet connection between two laptop computers, you'll need to connect them to a device called a router. A router physically splits an Internet connection in multiple directions, allowing more than one machine to access the Web from the same connection. Once you've purchased a router, all you'll need is three Ethernet cables--one for each laptop in the set-up as well as the modem--to make the connection and transfer data.

Purchase a computer router and three Ethernet cables. This equipment can be found over the Internet through various electronics dealers, as well as in stores at locations such as Best Buy or Radio Shack.
Plug one end of an Ethernet cable into the "Ethernet Jack" on the back of one of your two laptop computers. This jack will be the only one that the Ethernet cable fits into, so you don't have to worry about putting it into the wrong place.
Repeat Step 2 with the second laptop in your set-up.
Plug the other ends of both of the Ethernet cables that are connected to your laptop computers into the inputs on the computer router. Once you've done this, both laptop computers should be connected to the router via the cables.
Plug one end of an Ethernet cable into the Ethernet jack labelled "OUT" on your computer router.
Plug the other end of this same Ethernet cable into the Ethernet jack labelled "IN" on your Internet modem. Once you have done this the modem will be connected to the router, and the router will be connected to both of your laptop computers. You will now be able to share an Internet connection between the two machines.
