I have an AirPort Extreme (plugged into the router) and an Airport Express (sat next to the AirPort Extreme. The Express shows "connection unknown" in the Airport Utility, and a dotted line between it and the Extreme. I've reset both and set them up again three times now, and this is driving me nuts. Why can't the Express connect to the Extreme? The Extreme is setup as a wireless network, the Express to extend that network.
