I want to setup multiple access points using a few Airport Express units around my home. I have an Extreme already. Looking to get 3 Expresses to set up at various locations around my home to extend wireless range. They will all be connected via CAT6 through a Netgear Gigabit switch. I searched this forum and tried looking online but not 100% sure the best and correct way to do it. I'd like them all to have the same SSID or network name and show only as one network. As I roam around the house, I'd like it to drop one connection from the Extreme/Router or access point and reconnect to another access point if the signal is stronger. Similar setup to say a hotel or convention center. Multiple access points and as you roam around the facilty, it drops one connection when the signal gets weak and connects to a stronger one. The SSID never changes. How do I set this up using one Extreme and multiple Express units?
