So I have a dell downstairs and a comp that I just build upstairs (new one is in sig). Both are capable of getting to the internet through my dsl box, but only 1 at a time since I have to move the box to the one I want to use at the time. If I want to give dsl capability to both computers, would I need to buy a router, or maybe setup some kind of wireless network, since the physical distance between the two are so far apart? Need help!
