My local VAR is suggesting we purchase two or more Cisco AP1131AG access points. We currently have a couple mixed brand wireless routers that each service a specific area of the building and broadcast a unique SSID for each device. We want to get more serious on a small budget and create a better wireless network. We want to start with two access points and grow the network as budget permits. Each access point will have a wired connection to the main LAN. If we purchase what has been suggested will our new wireless network broadcast a single SSID from two or more access points? What will happen as client systems move between the building?
