To provide better coverage in an area with structural interference, I plan to set up multiple Wireless Access Points (not routers, as I want everyone on the same subnet) in a pattern that will overlap coverages to assure that users have access no matter where they may be in the facility. My question relates to configurations.
Do I give all 3 WAP’s the same SSID but on different channels, or should each one have a discrete SSID? The potential for multiple visible WAP’s in the overlap areas has me wondering if it is safe to use the same SSID on all of them, even though it has the advantage of requiring only one wireless network configuration in each user computer.
(Footnote for the security minded: In addition to WPA-PSK I am placing the WAP’s into a DMZ to insulate the core network from potential wireless intruders. Properly authenticated users can get to the core via VPN, but company guests (or intruders) will only have access to the Internet and a couple of printers.)
