Securing wireless connections

I do several thing to secure wireless connections for my customers, however
one of the key features I use is turning off the Broadcast ID ( SSID ) to
hide the name of the WLAN along with other security measures, however the
wireless network adapter/controler will not keep the Broadcast ID connection
as it does in XP. When you turn off the Vista computer/ laptop it forgets the
ID it belongs to. Due to the the amount of criminal behavior involving
unsecured wireless' I think that this would be important to your company to
make sure this works.
