Hi,

AFAIK "hiding" the ESSID merely means "not broadcasting it", i.e. not
letting the world know you're out there. Once a client knows the ESSID
of an AP (e.g. because a used entered it), it can establish contact
with the AP. Similarly, once a client has connected to an AP, it knows
the AP's ESSID, even if the AP later starts hiding it. The only way to
prevent clients from staying connected/reconnecting is changing the
ESSID as well as hiding it.

Jens
