Hi @Kinsey,
Thank you for posting in the community. I'm sorry to hear that your upstairs thermostat indicates it can no longer connect to the Wi-Fi while the downstairs thermostat is working as expected. I appreciate the troubleshooting steps you've tried so far. Don't worry, help is here.
To gather the necessary information and provide the best assistance, please answer the following questions:
- What type of Nest thermostat do you have? The following article could be helpful: How to tell which Nest thermostat you have.
- Does the Nest thermostat have a strong internet connection?
- Is there an error code on the Nest thermostat display when connecting it to the internet?
- Can your Nest thermostat find or detect networks?
- Could you describe the troubleshooting steps you've taken so far?
In the meantime, let's check for interference. Identify any devices that might be interfering with your Wi-Fi signal (like cordless phones or microwaves) and try moving them or changing your Wi-Fi channel. You can find more information here: Troubleshoot wireless interference.
I'll be waiting for your reply.
Best regards.
Derick.
