Subject: [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
