you need a router
You need to establish a network, either with wires or wireless. There are wireless internet kits that you can find in places like radioshack, Sam's club, etc.
wireless router
other solution:

connect one computer to the DSL. connect the two computers together, then bridge the two connections.
You need a router if the DSL Modem does not have more than one ethernet port.
Connect your DSL cable to a router, then connect the two computers to the router.

Check with your Internet Service Provider to make sure that you can legally use a router under the terms of your contract.
The best way is to use a router. The incoming DSL wire remains connected to the modem. Then connect a network cable between the router and the modem. Next, connect each computer to the router with a network cable. At this point, you may need to call your ISP to change settings if it doesn't work out of the box (most of the time cable does, telephone DSL does not). Some modems have built-in routers or firewalls. Good luck with it!
