Neil,
Thanks for the catch on the SSID. Actually, I find that I can only connect
when I do not specify the SSID. Documentation on wifi management is a little
hard to come by. I am learning the wifi packages and device/driver
functionality through trial and error, logging, and network monitoring. I'll
eventually get there.
