Just about everything I've read says that part of wireless security is to turn off your SSID. Does this prevent hackers no. But to the typical lUser, they will never know the network is there to use. I recently had someone point out to me that: "the SSID is like a homing beacon or the carrier signal that is used by your wireless network card to maintain a connection. This is especially helpful if you have several APs in the area, it helps your network card to maintain a connection to the correct Access Point." To my understanding, the ssid is just and identifier of which networks you can join or are a part of. Does anyone else have any info on this?
