Hi Aabdemur,
Yikes! I'm sorry to hear that your thermostat went offline though it has been connected to the internet. Let me take a look at this for you.
- What type of Nest Thermostat do you have?
- Is the thermostat display working?
- Can your thermostat find other Wi-Fi networks?
- How far away is the thermostat from the router?
- Are there devices or appliances (such as baby monitors, microwaves, cordless phones, etc.) near the thermostat?
- Can your other devices find your Wi-Fi network name (SSID)?
- Are you able to access the internet from your phone or computer?
- Do you only have one Wi-Fi network, or are there multiple ones? If there are others, Do any of them end in _ext?
- Are you trying to connect to the 2.4 GHz or the 5 GHz network?
- What’s the make and model of your router?
i'll look forward to your response.
Best,
Zoe
