Probably hte oldest router overloaded, as newtekie surmises.

Personally, I'd have your "M & N" routers inside the network, and the "L" as the splitter, but again, depends on the hardware. It's jsut that having wireless in multiple links dow nthe chain creates security issues..not that you'd probably have issues, I'm jsut a bit emo about that stuff. My wireless signal abrely touches the house outside walls.
