The same wpa_supplicant.conf is successfully being used on 2 other computers 
running the linux wpa_supplicant-0.4.5, 1 is a laptop with the ipw2200 driver 
and the other is a desktop with a Broadcom Corporation BCM4306 (using 
ndiswrapper). 

Anyway, I just booted the other laptop with the Netgear PC Card and now it is 
solidly working. Maybe I needed to wait longer? I did run ethereal for 5 
minutes if you still want to look at the log. Now, it's time to figure out 
how to set this up as a service. Thanks for the help.
