rod03801: You should have an ethernet card already. It will look like a 2nd phone jack in back but had a green light beside it. That would be all you need.

Check if they offer a wireless router even. The nice thing about that is you then have a choice of using the ethernet line or the wireless connection.

Most laptops these days come with the wireless card installed, so if you ever get a laptop you are all set.

And if Verizon ever offers Fios in your area, snap it up! Its worth every penny and even better than cable.
