Wireshark-users: [Wireshark-users] Viewing TKIP-encrypted data

Hi

A question about what I should be expecting to see when monitoring a WPA-PSK encoded wireless network. I have the passphrase set in the IEEE 802.11 preferences, with the option set to decrypt encrypted data. But all the data frames I see are just that: data, with nothing recognisable within them. What should I expect to see if the passphrase is set correctly?
And a curious point - when I look at the unfiltered packets, it is a  
collection of IEEE 802.11 and LLC protocols.  When I apply a filter  
to view an individual MAC address (using wlan.addr==<00...>) all the  
LLC packets are then reported as IEEE 802.11 packets.  Is this expected?
Regards,

David
