SSID

The Service Set Identifier (SSID) controls access to a given wireless network. This value MUST match the SSID of any/all Access Points that you want to communicate with. If the value does not match, you are not granted access to the system. It can be up to 32 characters long. The SSID is case sensitive. You can have up to three SSIDs. SSID2 and SSID3 are optional, and are for use if you have the need to roam between up to three distinct networks. For example, the wireless networks of two separate buildings could have different SSIDs, and a network administrator might need a laptop that could be used for both buildings without having to re-configure the card each time.
