Thanks all. Problem is my 50-year-old degree in Electrical Engineering didn't include Internet Stuff 101 and while I've kept up with it well enough to, for instance, trouble-shoot a campus-wide system in a hospital in the PNG Highlands, it doesn't take much to mess me up - and in this case you couldn't get a much more basic mess-up on my part - wrong password.
Anyway, down near the border and sitting under a big tree in the Walmart parking lot and the nanoStation is lying horizontally on the back of the copilot's chair pulling in a nice signal from Starbucks which is far enough away that I had no signal at all using just the laptop antenna. Google Fi is also connected to the gateway and updating all the stuff that I wont let it update on paid service ---- so I'm a happy customer.
The Google Fi phone and internet service is also performing as promised and swapping seamlessly back and forth between free wifi and Telco services depending what is available and is very easy to force it to not use anything that costs me money so that should be good too.
