|Friends and Fellow Geeks,|
Thank you for the responses and suggestions.
I find that struggling to frame a question that won't take you and me down long side paths and clarifications, actually helps order my thought processes in thinking about solving the problem. Other times, it reminds me of how much there is to know out there, and without good technical support (that's you folks!), I would be adrift at sea. Then someone smacks me on the head with an oar, and and says, Snap Out Of It!, and I proceed to the solution.
Ultimately, the solution for me included running an ethernet cable from the non-internet-connected router to the second PC, setting up static IP's for that network, killing the gateway and dns for them, and letting the wireless usb adapters do their thing for the wifi internet access.
The brain-fart had been that I was trying to force two networks on one adapter on the second PC - what was I thinking? Some times I need that smack upside the head.
Be nice to one another, okay?
