    Default WPA2 not decrypting in Wireshark (w/ 4 way handshake)

    I'm running BT5 in a virtualbox VM on a Win 7 host. I have a Gsky GS-27 external USB adapter (the poor man's Alfa) for playing with wifi. For the life of me, I cannot get Wireshark to decrypt the traffic on my wireless lan. My USB adapter is in monitor mode, I have entered my key in the right format in Wireshark's 802.11 properties and I've deauth'ed all clients and watched as all 4 handshake messages are exchanged in the capture...and Wireshark decrypts nothing...

    I tried associating with a totally different client as opposed to my VM host just to make sure there wasn't something going on between the VM and host that was messing with things but no luck.

    Has anyone run into this before?

    Honestly in order to give you the answer debugging of the wireshark should be performed first.
    Not an easy task by itself.
    Why do not you post your question on the wireshark developers forum?

    I should have posted this to a wireshark forum. Sorry about that. This thread can be closed.
