Ike,
Thanks. I made the changes you suggested, and ... nothing.

So then I started thinking about your first Q - was I getting an IP address? :nw: I found the IP address, and it was an impossible number (the first number was 4 hex digits, etc). So I set a fixed IP address to be the same as my lappy. After a soft reset, Odyssey beeped, and I saw the Odyssey icon to the left of the radio icon on the Today screen. Clicking that let me select my wireless AP by SSID. A few more clicks, then back to the WiFi adaptor to go back to DHCP, and voila - I was on IPAQ HQ with my PDA. Very, very nice! :D
I think forcing the IP address woke up something in the Odyssey client that gave me access I hadn't had before.
BTW - I like your WiFi intro and FAQ. If you ever decide to update the FAQ, under security, you should probably make changing tne admin password the very first item. For those users who set and admin password and then forget it, most APs have some kind of a switch that resets everything to factory default, including the admin password. Not that I have ever needed it, but I do generall ready the manuals, and I thought this was a particularly good idea.
