upgrading from on hub to nest Wi-Fi problem

[Mostam]

I can't get my nest Wi-Fi set up. I have an existing TP Link on hub mesh net work. When I try to set up the nest Wi-Fi router I get various error messages. If I leave the on hub routers active I get "we noticed you have an incompatible net work. Google nest can't be added to on hub Network."

If I power all of the on hubs off so there's no Wi-Fi signal I get "failed to connect to all addresses" that is with the nest router plugged into the Internet and powered up. 

I am stuck for ideas to get this to work. It's also frustrating that there is no telephone support. If I don't get this straightened out I'm just going to return the routers and switch brands.

I should add that's getting a QR code does nothing. It connects me to rubbish the message says "it looks like there aren't many great matches for your search."

 I take back the thing about telephone support. It took me about seven times going through the help process to find a place where you can be offered a phone call. Let's see if I actually get a call. It's amazing. I promptly got a call that went directly to voicemail. The phone did not ring. I don't know how to get them to call me back. Remembering this happened the last time I tried to get phone support. Totally frustrating product support plus someone with a real sets of sadistic  sense of humor set up this automatically go to voicemail.

Hi sorry we missed you earlier but unfortunately we can't take her number

Turns out I had call forwarding set on the phone so I did get a phone call. According to the person I spoke with I need to factory reset the net work in the Google home app and factory reset each individual on hub router. I'm not going to do that right now because I want to make sure I have enough time. I don't understand why I have to reset the on hub routers if I just disconnect them and reset the app will that not be sufficient? It's a little unsettling to factory reset all my Wi-Fi points and then be relying on the nest Wi-Fi to actually work. If I don't get it set up promptly I'll have no Wi-Fi. But I will try it when I have time and report back. You would think that since they're just continuing support for the on hub system they would anticipate that people would be upgrading and that they would be a special set of instructions. How would anybody know that they're supposed to factory reset everything in their system as well as the app?

Thanks for sharing. I'm upgrading from the orphaned TP-Link hub too and this had me stumped. This will be a popular post.
