I had a similar problem with Vista. Two XP laptops could connect, but the
new Vista one could not. The message was "this network is hidden" and all of
the help messages and forum threads pointed me toward changing SSID
broadcast.
Turns out the real problem was the Wireless Access Point was configured to
only allow specific MAC addresses connect. The error message for this and
for SSID problems are the same, hence the misdirection.
Resolution was:
1. Open up a command prompt window on the laptop
2. Run ipconfig /all and write down the physical address of the wireless
adapter
3. Log onto the Wireless Router, add this address to the list of allowed
MAC addresses
