I'd like to add a second computer on my existing cable connection. What do I need to do this? I don't care about wireless since the new system will be located fairly close to my existing one; I just want to do whatever's cheapest that can provide a fast connection with plenty of bandwidth to both systems. I was wondering, is there any way to vary the bandwidth going to one computer (preferably from the other computer, ie within a software program)? What I'm thinking is, I don't want someone downloading stuff on the other system to slow down my connection too much if I'm gaming or also downloading something. Also, is there a convenient way to browse/share folders between the two computers? I.e. if I want to obtain a file that was downloaded onto the other system?
