Hi,
Sorry those other guys couldn't help you. It sounded like solid advice, but it required that you know a bit about networking. Do you mind if we start from the beginning? What is your problem? YOu obviously have an internet connection. Is this without the router? When you connected your router, you said everything worked fine, does this mean you had access to the internet on both compas and both comps could trade files? What are your current issues? These are the questions that can help us greatly. Give me alittle more info and I'll be glad to help.
As Always,
D
