Nest thermostat can't see wifi

[james_salop]

Noticed via the Nest app whilst on holiday that our Nest thermostat hadn't been connected for over 30 days. Now we're home I've tried every solution I can find but it's still not working. I've tried:

• Powering thermostat on and off
• Alternative USB power sources
• Restarting wifi
• Manually inputting wifi network data (said it couldn't connect)
• Factory reset and reconfiguring thermostat

...but I still get an error message on both the thermostat and the Nest app that the thermostat "couldn't connect to Wifi". I've tried the thermostat physically touching the router, the extension hubs, and also my iPhone when its personal hotspot was on. The thermostat cannot see any wifi networks. 

This is seriously frustrating. I'd appreciate some help please! Thanks.

It sounds like you've already tried all these steps:
Nest thermostat is offline - Google Nest Help

If the thermostat doesn't show any Wi-Fi networks at all, not even a Wi-Fi hotspot, it's possible there may be a hardware issue. I'd recommend that you contact the Google Nest support team.

1. Go to Contact Us - Google Nest Help
2. Select an appropriate product or category, type a brief description of the issue, then click Next.
3. Click Other, then click Next step.
4. In the Resources section, click Next step.
5. Choose to get a phone call, call or chat with the team, depending on availability in your country.

Thanks David, I've had an online chat with Google Nest Support and they're sending a replacement out 😊

Removed Nest app on iPhone.  Installed Google home.

Installed Google nest hardware. All good. Could manually change best to heat or cool. 

Could not sync to wifi. All other devices(laptop, iPhone, tv) could sync to wifi.

Uninstalled and reinstalled Google home app. Continued to get " cannot connect to wifi"

5th time of installation decided to "create new account " at point of identifying the Nest by naming it to a new location (den)

Followed rest of installation and immediately connected to the wifi
