wpa_supplicant WPA_PSK: not working with Value Point AP --HELP

Hi, Jouni,
 
Thanks for the analysis. The trace was what we got for one wpa_supplicant cycle (10 seconds).
Looks it could be an AP issue. It just fails to response anything after association. Just not sure
why Windows XP built-in client can successfully talk to this AP.
 
Best Regards,

Thanks. In general, I would prefer capture logs in a format that can be
easily read with ethereal (e.g.., capture file from ethereal itself or
tcpdump).

The capture log was cut somewhat short, i.e., it continued only for
about 130 ms after the association. During that time, the AP did not
seem to send out any EAPOL frames. If no EAPOL frames is received even
after this, it looks like the AP is doing something odd and there is not
much that wpa_supplicant could do here. The association seemed work
correctly and the next thing would be for the AP to send the first
EAPOL-Key packet of the 4-Way Key Handshake.

The capture log did not indicate that anything like that would have been
send out at least during the 130 ms period after the successful
association.
