Our house's router is fizzing out, and we need to get a new one. But me and my roommate are in disagreement here. He swears that when he used to run an internet cafe all eight computers were hooked up to a plain ol' hub sharing a DSL line and everything was hunky dory. But everything I know about networking (which isn't a ton, granted,) leads me to believe that you CANNOT share an internet connection like that. You need a router so that it can pick up the WAN connection and share it between the LAN computers, since you're only allowed one IP address on the WAN side by the ISP. How can a hub without routing capability share a cable internet connection? Wouldn't it by definition be a router then?
