Mike,
I'm making your solution available to the rest of the TDG community.
Solution:
Space characters in the SSID were the culprit. There are two options.
1. Do not use space characters in the SSID
2. Modify line 125 in wpa_supplicant script:
From
WPA_PSK=`/usr/sbin/wpa_passphrase $WPA_SUPPLICANT_SSID $WPA_SUPPLICANT_PASSPHRASE | grep ' psk='`
To
WPA_PSK=`/usr/sbin/wpa_passphrase "$WPA_SUPPLICANT_SSID" $WPA_SUPPLICANT_PASSPHRASE | grep ' psk='`
NOTE: (Added double quotes around $WPA_SUPPLICANT_SSID)
