This is happen in one of site office in my company.
when crowded,all client that connect to AP disconnected. and the SSID is gone. after a few minute it show up again. and we have ZoneDirector at main office.
and the internet speed quite slow.
is there possiblity that because the internet slow AP lost contact to ZD so all the SSID gone?

Your low bandwidth is probably becoming congested, causing the AP to lose connectivity to the SZ. Normally not a problem with SZ (Unless you're tunnelling), but make sure you turn off any 'automatically reboot AP if connectivity is lost' on the SZ AP settings.

i'm sorry i just got info the AP in the site office is standalone. not connected to the smartzone. 
In what menu i can find the settings to automatically reboot AP?
