What is the difference between wpa, wpa2 and mixed mode, particulary how 4-way handshake packets look-like for every type? Is there any good lecture about it with packets examples?
Above question came to me because I'm working on college thesis, which involves some wireless network sniffing and I observed, that most routers send eapol packets which are marked as a wpa1, but encryption has value 2 (AES+CCMP) and in router configuration there is WPA2 standard set. So I'm really not sure if I can base on my own observation to correctly recognize standard of tested network.
