The bad news is I can be impatient.
The good news is that means I reflashed Raspbian, fired up the Pi and connected to my wireless network no problem.
The other good news is that now I'm trying to control the Pi from an iPad and, of course, as I follow the various tutorials that blythely explain how easy it is to do this, I am finding that nothing works the way the tutorials say it should. So I'll be starting a new thread on this topic.
Thanks to everyone for their help and suggestions.
