I go to college, so we have the worst internet connection in the world for gaming. Is there a way I could hook all four of our computers together without plugging anything in to the internet. Someone told me I should be able to do it with a router and I should probably get a wireless router so I don't have to trip over cords. What do I need to do, and if you could explain in detail because I'm a little slow when it comes to things outside a computer. Thanks Guys
