Wireless card problem

yesterday I called my isp to know how to install wireless internet with the new bell modem (2wire that is a modem and a router at the same time). I have windows vista and he asked me to go to connect to , i checked my stuff and there was no networks for wireless. So i went to device manager, there was a device called 6080 or 60to i dont remember and i think it was my wireless. I updated the driver (since it had none) and it disappeared? What is the problem? How can i know if i have a wireless adapter or a card?

Thank you

 

Nvidia nforce networking controller , thats it. Earlier in the day, I had another thing 60TO or 68TO and i installed the driver and it no longer shows. What do I do to see if I got one? could i do something like type something in commande line? download a software to check my network card manufacturer? Maybe I don't even have one. And i think yes the modem have wireless capabilities ( the technician told me it did).
