I'm trying to setup an Airport extreme to serve a single function: Route data through a wired ethernet cable to and from linksys wireless router that's connected to the Internet. The airport extreme needs to connect wirelessly to the linksys router. Here's what the setup looks like: I've tried combinations of "join a wireless network", "extend a wireless network", bridge mode, etc... but I can't figure it out. As I said at the start the Airport purely has to route between the PS3 and the wireless router, nothing else. It doesn't need to allow any other devices to connect to it. The reason I'm going for a wired connection from the PS3 is that it's Wifi is atrocious and the only way I've gotten decent speed out of it is with a wired connection. Any guidance on how to get this setup to work?
