https://www.googlenestcommunity.com/t5/Nest-Thermostats/Nest-Thermostat-error-260-WiFi-connectivity-issues/m-p/72125#M16196 <P>I am setting up my Nest Thermostat and receiving an error that the unit is unable to connect to WiFi. Subsequent to that, I started to receive error code 260 indicating that the Y wire was not connected. I was able to install the first Nest unit without issue, but this 2nd unit is an issue. I have reconfirmed that the Y wire is properly connected, and have followed all instructions on bouncing the WiFi, etc. Still is not working. Any suggestions? Thanks in advance...</P> Tue, 28 Dec 2021 23:42:02 GMT jwolin10 2021-12-28T23:42:02Z https://www.googlenestcommunity.com/t5/Nest-Thermostats/Nest-Thermostat-error-260-WiFi-connectivity-issues/m-p/72125#M16196 <P>I am setting up my Nest Thermostat and receiving an error that the unit is unable to connect to WiFi.
