Question regarding WPA-PSK 4-way EAPOLs (wpa-supplicant 0.3.9)
Wed Sep 28 23:08:46 PDT 2005
Normally EAPOL timeout at Cisco AP is 100ms (seen also in Sniffer).
wpa_supplicant responses are quicker than that.
I'll give it a shot though :)
Attached to this message is an Airopeek sniffer trace showing the failed
handshake. I would really appreciate if you could take a look :)

I had a very similar issue last Thursday with certain cards (using the
wpa_supplicant windows port), using Cisco 1100-series APs. It seemed to
be timing-related (even clients that did finish the 4-way handshake were
having some minor issues). After changing to version 0.4.5 (which
includes a change to the interval that wpa_supplicant checks for new
packets from winpcap while doing EAPOL), the issue went away.
Might be worth a shot, at least (but keep your old executables around
just in case).
