Ok, capture file attached. The differences I can see are the following:

- Windows starts by requesting a WPA key of length 0, and then tries
    again requesting a key of length 32.
- There is no group handshake??? All I can see is the following:

1. STA -> AP	EAPOL start
2. AP -> STA	Key req (len 0)
3. STA -> AP	Key
4. AP -> STA	Key req (len 32) (1/4?)
5. STA -> AP	Key (2/4?)
6. AP -> STA	Key (3/4?)
7. STA -> AP	Key (4/4?)

and then data. Is this possible? Using wpa_supplicant I also see group 
key exchange mechanisms. Or is the group key exchange encrypted using 
the pairwise key, so I can't see it using ethereal?

Any ideas?
