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
