Hi folks, I wanted to post it here on this forum, if anyone is having issues with Asus,Zen Wi-Fi router, and having it cause the Nest thermostat to lose connectivity in the app. I fixed it, the way I did this was by setting up a 2.4 GHz guest Network and setting it so that Wi-Fi network only connected to the router and not the secondary mesh node.
Once I built this new guest network, I changed my Nest thermostat to connect to it only, and I have had no issues with it dropping since.
Hope this helps other folks, it took me three hours of fiddling to make this work. Bless you all!
