Ok, get a wireless router unless you want to pop holes in your walls and run 2 million ft. of ethernet cable. Anyways get your router (wireless prefered) and run your exsisting ethernet cable from your modem into the "internet" port on the back of the router. Now if you are going to hardwire everything just run cables from your 2 computers into the ehternet ports on the back of the router. If you want wireless, get a wirelss adapter for each computer thats not near the router ( other room, across the house, etc.) I like the USB adapters for desktops because you can move them around and you don't have to physically install them. That's the hard part ( to some ). Get there, fallow the directions on the disc you get, then you should be online. If you can't do this shit, get a friend or family member, resort last to electronic store installers because it will run you a few hundred for them to do this process, and they usually only do wireless anyway.
