Google Nest's first suggestion is to use the same network name (SSID) and password on your new modem/router that you used on your old modem/router.
Otherwise, you should remove the Google Nest device from the Google Nest app or Google Home app while you are still on your old Wi-Fi network, do a factory reset of the device, and then re-install it.
Thank you for bringing up the concern you're experiencing, I would love to look into this further for you. @MplsCustomer is providing some fantastic troubleshooting steps which should help you out. I'd also recommend that you restart your device. This process should keep all your settings, and reconnect it to the same Wi-Fi network. This is helpful if it ever freezes, has connection problems, or isn't working normally. Please let me know how it goes.
@rlynne how's it going with your Nest doorbell? Aside from restarting it, you may reset it to the factory default then remove it from the app and then re-add.
Just one quick final check in here since activity has slowed down. We'll be locking the thread in the next 24 hours, but if you still need help, I would be happy to keep it open. If there's more we can do, just let me know.
