If I attempt to use the hex key... it fails to parse the wpa_supplicant 
file!?!  The AP is a linksys something-or-other... and when you type in 
a cleartext passphrase it generates 4 hex keys.  I have tried both the 
passphrase and the hex keys.

Yes... I can connect using the following script

ifconfig ath0 ssid office-g
ifconfig ath0 mode 11g channel 6
ifconfig ath0 wepmode on
ifconfig ath0 weptxkey 1 wepkey 0xD8<mykey>65E5A
ifconfig ath0 192.168.1.99
ifconfig ath0 netmask 255.255.255.0

rm /etc/resolv.conf
echo "nameserver 198.6.1.122" >> /etc/resolv.conf
echo "nameserver 198.6.1.142" >> /etc/resolv.conf
echo "nameserver 198.6.1.146" >> /etc/resolv.conf

route -q add default 192.168.1.1
