Do i need a phone cord and ethernet for 2wire and

The basic modem connects one computer to the Internet through your service provider. The modem should already be connected to your service provider with whatever cable is necessary. You need to disconnect the Ethernet cable from your computer and connect the modem's network jack to the router. You probably got an extra cable in the box with the router, so use that to connect one of the router's wired connections back to the computer. Once you've done that, you access the router using your Internet browser. Follow the setup steps on the router to configure your wireless network. There should be a manual on the CD that came with the router with the information you'll need. There may also setup software which will take you automatically through the process.

of course you do because you are giving access to your internet provider...
