How do I run two routers at once?

Episode 937 (16:30)

Brian from New York, NY

Brian is having router problems in his house because it won't cover the entire area. He's created a bridge, but his wireless devices won't switch automatically from one access point to another.

Leo says the second router needs to be in "bridge mode" and not in active router mode, this will make it a repeater and wont allow the second router to assign an IP address. An easier way to do this would be to get a wireless access repeater that runs WDS.
