When I initially setup my APs I was told that broadcast SSID had to be on for machines to roam between APs. Now I would really like to turn off the broadcast. Anyone running without broadcast and roaming ok?
We currently have broadcast SSID turned off and have for over 6 months. We roam between access points on a regular basis and have had no problems. The clients know what the SSID is and therefore they send a broadcast with the SSID and the AP responds. You should not have any problems turning off broadcasting SSID as long as the SSID is configured on the clients.
Broadcast SSID is evil. Unless you want to operate a 'Hot Spot'.
Turn it off and don't look back. You'll hear from any user that doesn't have the right SSID set for their machine very soon.
Do realize that SSID alone will not protect you, though. Anyone with the right software tool can still grab the SSID out of the air, so please consider WEP or other encryption and authentication services.
