Wireless Connecting Issues (Unidentified Network) [Vista]

My laptop connects to my school network however it will not connect to the internet. I have contacted my school's help desk and they cant seem to fix it. When I check the connection it shows:

Unidentified Network (Public Network)
Access: Local Only
Connection: Wireless Network Connection (NYIT)
Signal Strength: Very Good

I have tried to get new ip settings, and reset the network adapter but it didn't help.

I think the problem is that it can not identify the school's network, every so often it would try but it keeps displaying unidentified. I don't know what else to try.

 

Have you looked in Network & Sharing Center and clicked the red X to the left of the internet icon.

Also, have a look, here http://support.microsoft.com/kb/928233 and here http://www.chicagotech.net/vista/vistalocalonly.htm

 

I have tried both suggestions and i cant seem to find an answer that works...can anyone please help me
