First I needed to get the source files for the kernel and ran make, make install from /root/madwifi which worked. Tried the script to restart the network, bring up ath0 and bind to the ap, which did not work. Still received the original post message. This led me to some additional research where I discovered this message references a problem with the opensc.i386 0.9.4-5rhfc4.at. I ran the yum list opensc which gave me the binaries I needed. Then ran yum install opensc to install the necessary files. Once this was done I performed a shutdown and restarted. I was able to run the script without an error, and ran wpa_cli to see what was happening. At this point I observed the following messages.
<2>Associated with xx:xx:xx:xx:xx:xx
<2>WPA: 4-Way Handshake failed - pre-shared key may be incorrect
<2>CTRL-EVENT-DISCONNECTED - Disconnect event - remove keys
This message repeated several times, connect, disconnect,......
So, I re-ran wpa_passphrase essid passphrase and copied the output to the wpa_supplicant.conf file. Reconnected and received the same messages. Did not work....
Checked the wpa_supplicant file, and discovered I had changed the eapol_version=x from the default of 1 to a 2 which is used for wpa_supplicant based on IEEE 802-1X-REV-d8. This specification is not used on all AP's. Changed my listing back to the default of 1 and SUCCESS!
