Hi,
    Does anyone know what is going on here. I am running the latest
madwifi-ng, and the latest WPA Supplicant available through CVS and
Subversion. Basically my wireless client functions with WPA PSK for a
random amount of time, sometimes minutes and sometimes hours then the
Supplicant seems to blacklist the access point and I have to restart the
Supplicant and Dhcpclient. I have had this problem with
wpa_supplicant0.4.7 as well. Below is the log from where it breaks after
the last successful group handshake. Is this a configuration problem or
a WPA Supplicant problem ? Any input would be appreciated.

Thanks,

Brian
