font-family:Arial'>The wpa_supplicant 0.3.9 running on Windows XP starts
getting the handshake failure after I upgraded the Cisco Aironet 1232AG AP from
IOS 12.3(2)JA to 12.3(7)JA. Although it seems to be a Cisco issue since
the only variant in this case was the IOS version upgrade, other supplicant
software like Windows Zero Configuration and SecureW2 continue to work without
problem. When the connection failed, the Cisco Aironet reported handshake
timeout after sending “PTK msg 1”. Likewise, the
wpa_supplicant would drop and try to associate again. This process
could go on for many times before the wpa_supplicant finally connected with the
message “WPA: Key negotiation completed with 00:13:…. {PTK=CMP
GTK=TKIP]”. The AP handshake timeout is set to 100 ms by default.
I am not sure if this timeout value could be adjusted (pending on the vendor’s
reply). Nevertheless, with the wpa_supplicant, I would like to know if the
key exchange process be tuned to fix this timeout issue. Has anybody
experience the same issue with the Cisco AP and has a work around? <o:p></o:p></span></font></p>
