Ok here is the situation. I have a computer upstairs with a router that runs a cable to the basement to another computer. I'm wondering if there is a way to hook up a third computer in the basement from the second computer. I run a DFI mobo that has two ethernet ports. Is there a way to run that third comp from my DFI comp? I just don't want to run another 25' of cord to the basement if I don't have to.
