Solved: Google smoke detectors and thermostats not connected to internet

[Icenavigation01]

4 wired google nest smoke/co2 detectors and 2 google nest thermostats disconnected from wifi 2 hours ago.  2 battery google nest smoke/co2 detectors, 2 cameras and one google door bell cam still connected to wifi. What is the issue with this product and how to fix it?

Well, equipment is less than a month old and that should be a sign for defective equipment. Will be using the warranty process and see how that goes.

Took a couple days to get back to the property and power cycled the modem/router.  The equipment that updated came back online.  Problem fixed
