T60: Connect Iphone to Ad-hoc with WPA2 on Win 7?

[propellen]

Hi,

Have you guys with Intel Wifi 3945ABG cards and Windows 7 created a WPA2 protected ad-hoc network which successfully works with the Iphone?
I have not :-] My iphone reports "unable to join the network" when entering the password. Ad-hoc network with WEP encryption works fine.

I'm running the latest official Intel Wifi 3945ABG driver from Lenovo (v. 13.1.1.1)

Thanks :-]
