Nest thermostat will not connect to WiFi. It worked fine for over three years. Please contact

Dear Nest,

my thermostat worked fine for over three years and this summer it stopped connecting to Wi-Fi.  I have done the troubleshooting steps for over three times,   my nest cameras work fine here and in my other home as does my other nest thermostat.    Can someone please contact me?    do I need to get a replacement?  I like the features of the nest, but I don’t think it should wear out after three years.   After reading all of the posts here, it seems like there is a systemic issue.

I’m having the same issue since my phone automatically upgraded to iOS 18.1.1

Hi Jimboboalooba,

Thanks for posting here in the community. I understand how inconvenient it is when your Nest thermostat isn't able to connect to the WiFi network after upgrading the iOS software version on your mobile device. I'd be happy to help!

To better investigate the inconvenience, I'd like to ask the following:

• What is the model of your Nest thermostat? Here’s a helpful article about how to identify the model of your device.
• Did you get any error code?
• Can the thermostat find or detect other networks?
• Is your thermostat device still connected to the network, or was it just disconnected from the app after upgrading to the iOS 18.1.1 version?
• Has your thermostat ever connected to your network?

In the meantime, I'd suggest checking this article to perform some steps: Troubleshoot connecting a Nest thermostat to the Nest app or Wi-Fi network (Other TD error codes)

Please feel free to share any additional details that might be helpful.

Best regards,

Jenniffer
