Nest Thermostat Not Connecting to Wi-Fi: How to Troubleshoot
1. Check if Your Router is Turned Off
If your Nest thermostat isn’t connecting to Wi-Fi, your router might be turned off. Perhaps you switched off the router and forgot to turn it back on.
To know if your router is on, check if any light on the router is on/flashing. If you don’t see any light on the router, the router might be turned off. As such, you’ll need to turn it on.
If your router has a power button, press the power button to switch it on. If not, unplug it from the power outlet and plug it back in. This should turn the router on.
After switching on your router, wait a few minutes to let your router boot. Then enter your Wi-Fi network details in the Nest app and try connecting the thermostat again.
If the device doesn’t connect to Wi-Fi after this, continue to the next step.
2. Power Cycle Your Router
Another fix to try if your Nest thermostat isn’t connecting to Wi-Fi is to power cycle your router.
Take the following steps to power cycle your router:
- Switch off your router.
- Remove your router’s plug from the power outlet. Then wait 10 seconds and insert the plug back into the power outlet.
Power cycling your router should refresh your Wi-Fi network and fix some errors obstructing the connection.
But if your thermostat still doesn’t connect to Wi-Fi, the router might still contain some errors. In that case, continue to the next tip.
3. Change Your Wi-Fi Band
If you have a dual-band router, check what band your router is operating on and switch to another band.
Nest thermostat works with the 5GHz and 2.4GHz Wi-Fi bands. However, the current band your router is operating on might be malfunctioning. So, check and switch it to another band to see if it solves the problem.
You can change Wi-Fi bands via your router’s admin web page. Refer to your user manual for guidelines.
If the connection problem persists after trying a different Wi-Fi band, continue to the next step.
4. Move Some Devices Away from Your Router
Some devices/materials like microwave ovens, baby monitors, concrete walls, metal blinds, etc., may interfere with Wi-Fi signals while your router is transmitting the signals. This prevents your thermostat from receiving these signals. Due to this issue, your Nest thermostat won’t connect to Wi-Fi.
You can protect Wi-Fi signals from interference by putting these devices away from your router. Or keeping your router where concrete walls/metal objects won’t interfere with the Wi-Fi signals.
More so, you may consider getting a Wi-Fi extender to boost Wi-Fi signal strength in your home.
If this checks out and your Nest thermostat is still not connecting, continue to the next step.
5. Bring Your Thermostat Closer to Your Router
A weak Wi-Fi signal may also prevent your Nest thermostat from connecting to Wi-Fi. Your Wi-Fi signal may become weak because your thermostat is too far from your router.
To resolve this issue, move your thermostat closer to your router. The devices should be at least 30 feet closer.
Once your thermostat is close enough to your router, your Wi-Fi signal will become stronger. The thermostat should then connect to Wi-Fi.
If the problem persists, go to the next tip.
6. Check that You’ve Entered the Correct Password
If you enter the wrong Wi-Fi password in the Nest app, your Nest thermostat won’t connect to Wi-Fi.
Did you enter the letters in the incorrect cases? Or you just aren’t sure what your password is. Whatever the situation is, you’ll need to check that you’ve input the correct password.
Here’s how to do that:
- Tap the Settings app on your phone to open it.
- Click on Connections and Preferences.
- Select Wi-Fi. A list of Wi-Fi networks will appear.
- Find your Wi-Fi network in the list. Then click on the gear icon beside the Wi-Fi network. You’ll see the Show Password option.
- Tap Show Password to view your Wi-Fi password.
- Now, enter the password in the Google Nest app.
Your Next thermostat should connect to Wi-Fi once you’ve input the right password.
However, if the device doesn’t connect to Wi-Fi, proceed to the next tip.
7. Factory Reset Your Router
If your Nest thermostat is still not connecting to Wi-Fi after applying the fixes above, you might need to factory reset your router to fix incorrect settings or unseen glitches.
Follow the steps to factory reset the router:
- Find the reset button on your router. This button is usually located in a tiny hole at the back of your router.
- Ensure that your router is turned on.
- Next, get a paper clip or a pin. Use this object to press and hold the reset button for 15 seconds.
- Now, release the button. The device will go off.
- Wait a few minutes for the device to finish resetting and turn back on.
Note that the reset method for your router may differ—depending on the brand. If this reset method doesn’t work for you, refer to your user manual for guidelines.
As mentioned earlier, a factory reset will eliminate any errors left in your router. Please note that all the information you’ve saved on your router will also disappear after resetting it.
After factory resetting your router, connect your phone to your Wi-Fi network. Then try surfing the internet with Wi-Fi. If your browser loads website pages quickly, the router is working properly.
However, if you can’t browse the internet with Wi-Fi, your Wi-Fi connection might be problematic. As such, you’ll need to contact your ISP.
Once you’re certain that your router is functioning correctly, try connecting your Nest thermostat to Wi-Fi. If the thermostat doesn’t connect to Wi-Fi, move to the next step.

- Press the ring of your thermostat to open the Quick Menu.
