Windows on BootCamp is unable to connect to WiFi

Hi all

I've installed Windows 7 with bootcamp. Drivers were installed from Apple automatically, Windows works great!
I can connect the WiFi at home and others locations but when I try to connect to my company's (Security Type: WAP2) I have the error: "Windows is unable to connect to ..."

What I did:
- I've created the wireless network manually.
- I've created as well in two different Windows 7 laptops (no bootcamp) and the connection works fine but the same settings don't work in bootcamp.
- I've checked the drivers, I have the good one and updated.

Please someone can help me with this?
Thanks in advanced

Try this:

In Windows, select "search for networks". When your company network is found and displayed, click connect. Windows should respond with a dialog asking for the password. Enter it. Windows will ask you to enter it again to verify. Enter it again and you should be able to connect as soon as an IP address is generated.

If the above doesn't work, it could be your company is using a Proxy for additional security. Check with your IT folks.
