Finding the SSID of a Wireless Network

[rab]

Is there a way to determine the SSID of a wireless network? I have never 
been able to connect to a hotel network or one at my university, even 
though it works fine with my home wireless network. I don't understand 
why I can't connect. I set up the card to use DHCP. At the unversity, I 
even put in the SSID. The card is a D-Link DWL-650 (uses the prism2 
chipset). The card works perfectly with my home wireless network under 
Linux. I've tried using the card under XP (the laptop dual boots) but 
even with the latest windows drivers, XP crashes EVERY time if the card 
is plugged in/
