Upon arrival inspected thermostat and found it in “waiting for update” could not connect to the WiFi and after I removed the saved WiFi memory it wouldn’t let me reconnect at all continued to throw error. Test replaced the thermostat to verify not an internal issue and still won’t connect. Homeowner couldn’t connect her laptop from that room either. Believed issue was in the router for that portion of the house recommended she reset that router or have the company come out so she called them.
