Help I have 2 desktop computers eash one is on each end of my house. And I just had road runner hooked up to one. And would like to hook the other one up. So what do I need to set the other one up to the internet. I was told all I need is to put a wireless router on it. Then I was told that I would put the router on my computer and a antenna on the other one. Help I don't know what I need . I have ordered a wireless router, but is this going to work with out a wire from one comuter to the other they are about 80 ft from each other.
