I have a Time Capsule and an Airport Extreme in my home. The Time Capsule is in a corner of the house connected to the cable modem and the Airport Extreme is in the middle of the house connected to the time capsule through an Ethernet cable. As of know I have both of them broadcasting separate wifi networks with different SSIDs. Is there anyway that I can set them up so that they have the same SSID and my devices switch between them depending on which has the stronger network?
