I currently have Dial Up and i can not stand it. I called up Road Runner today and asked for a quote, and I was quite satisfied. Before I do any commitments or dumb decisions, I have a few questions.

I have a computer in one room, a computer in another room, and a computer upstairs.

Do I need a Modem for all three computers [to share one IP address] or can all three run of one?

Could I just purchase a Wireless Modem and have all three run off of that?

What problems would I run into if all three were sharing one modem?

Somewhere it stated I would need a router. Would I need two routers or just one?

Would those router[s] need to be connected from one computer to another? Like, how would I connect the upstairs and the downstairs to one router/modem [whatever].

Is there a certain modem I would have to buy? Like special coding or whatever.

Sorry for all the questions, but I really don't know much about internet connections!!
