can't connect to wireless, but window can.

I am currently using dual boot with window 7 and karmic. I am a college student. I usually connect to internet throught the wireless network that provided by my college.
Last month, the wireless network is upgraded. then, after that, my ubuntu can't connect to the network anymore. However, my window can connect without any problem. The network manager is able to see the network, but fail to connect it.
It is not driver problem, because I used to connect it with ubuntu and I can connect to other wireless network.
My wireless card, is Intel 4965AGN.

ps: I post this through my window 7. May not give respond immediately.

can connect now. My friend told me to try to choose 'connect to hidden wireless network' by typing the name of the network.
Then, I can connect it now. However, i don't know what is the problem but at least it is solve.

ps: By using the network that network manager found, I use the manual connection by type in the ip, dns, gateway, netmask. The connection still can't establish.

Is the thread solved?
