I see EAPOL key coming in on the client and it is answering to the
correct MAC address, but the AP is always just saying EAPOL key
timeout on 1/4. On the AP side i do "tshark -i wlan0" and see the
EAPOL key going out but nothing is coming back. However, I am reading
up on the subject because as of now I must admit that I do not know
how this works. I should be able to give a better description of my
problem in a week or so (after becoming junior guru of wifi) :) I did
get this setup to work before but after upgrading to Debian testing it
just wont.

BR,
