All right, so what I did is take a working and non-working on the same Linux machine. I have never done that, and didn't find much information about how to do that so I used kismet. I don't know exactly how I should export these logs for you to browse them but I gave a shot at interpreting them. What I can see is that in both cases the authentication request is exactly the same, except for the sequence number. Yet in good case there's an acknowledgement, and in the bad case there isn't. The authentication response does come back in both cases though, it's just the acknowledgement that is missing. Unfortunately I cannot figure out for which message it's the ack. Also, I notice the sequence number received from the router doesn't seem to change. All the authentication requests received have the same number (256). Another peculiar thing is that in the failed case the SN we send starts with 0. I suppose since the authentication ack never arrives, the next steps are never completed. Does that help? -- Felipe Contreras
