I have two Nest WiFi thermostat in my home. One has repeatedly starting disconnecting from my home WiFi network. It is obviously not my WiFi network as the other thermostat works fine. If I reboot the thermostat or reconnect to WiFi it connects for short time and then disconnects after few minutes. The only thing that changed when I started noticing this issue was when I installed a new Asus AX 6600 triband mesh router in my home and the main router was moved to the room that has the thermostat. Any suggestions what could be wrong? I went through all the steps listed on troubleshooting page but everything they point out seem to be working fine.
