1. Check with the laptop maker for latest drivers.

2. Now go to the IT office and see if they can get it to work.

3. If it fails, make it a warranty issue.

4. That move to WPA2 seems premature since I'm finding many adapters are not ready for WPA let alone the authentication you listed.

5. If push comes to shove ask which PC-Card or Express card works with your laptop and their network. Disable the onboard wifi and use the card.
