routers

im bringing my comp to a friends house in a couple days, and we both want to have interweb access. he's currently on a single line from a router that we don't access to (it's a duplex and the router is in his neighbor's place). i have a router of my own, but have never had any experience hooking up a router to another router. can we hook up my router to his line and then both our comps to my router and have net access? if so, how (will i need to set up my router differently than if i was just connecting it directly to a modem?)

both routers are generic linksys models. any help would be appreciated

Nobody uses phone lines anymore. Cable still uses modems, but DSL does not. Either way, that's irrelevant to the case at hand.

Depending on how your ISP hands out IPs, just connecting your router and then connecting both computers to that router could work (and will work just as easily as if you connected your own computer directly to your neighbor's router), but you may have to fuck around with NAT, which is no fun for anyone.
