Interesting observation on Wireshark...
Have a neighbour with a new N66U AP - nice unit
The box is configured with WPA2-PSK - but in a wireshark capture, something I noticed is that the box is sending out STP frames, and more importantly, sending them out TKIP, not AES.
So a couple of questions:
1) Why is the N66U sending out STP frames? Useful perhaps in Mesh WiFi networks, but useless in a home environment
2) Why is a TKIP vector present in the STP frame?
