My N800 also have same problem...since OS2007 to OS2008, Seem Nokia don't have any intention to solve this problem. [Edit] My cert is NOT private key / password protected.

My wireless is using Cisco AP and MS IAS (radius) to authenticate with our MS AD.

1. The N800 didn't show my AP as the predefined AP (always no tick mark).
2. SSL certificate in the list always empty, even I imported successfully.
3. Always ask for the WEP key, the N800 didn't detect as PEAP. (may be related to #1)

I don't understand why my Nokia S60 phone can work, why Linux can't work.
