David_K, thank you. I had spent over 5 hours on this, and after posting my question I left in frustration for a few hours. Upon returning, and seeing your reply, I dove in again. I think the only difference between what I had been doing and the steps you suggested was shutting everything down, including the modem and the Home app, before restarting from scratch. That seemed to do the trick. Each of the 3 pucks took some time, and a few attempts, before the app recognized them (I think the factory reset instruction I had attempted to issue hours earlier finally took hold, judging from the sequence of status lights, and I needed to allow each one to complete the reset and prepare itself for a new network pairing), Interestingly, the original network was gone, but I was able to set up the new network using the same name and password, so all of the network devices were able to connect without having to re-do anything. That's big when you have nearly 20 devices connected. At the end of the day I wish Google had a better support model. It is really hard to get support over the internet when you have no internet. It is really hard to set up a network when the setup requires a network app. These things work fine (usually) when you set them up out of the box, but when something has gone wrong it is a royal pain to get it working again. What I really needed was a phone number to call and a real person to speak to. I could have cut about 4 hours, and a hefty rise in my blood pressure, from the repair time. Having said that, I would have been dead in the water indefinitely had you not provided the response you did. So, a hundred gracious Thank You's. I am glad that you were there.
