Changing the Wi-Fi network that your devices connect to isn't something you need to do very often. But when you do — such as when you install a new router or change the name of your Wi-Fi network — it can be tricky working out what to do.
Things can get even more complex when you're working with devices that don't have a way to change this on the device physically, like a smart home products that's specifically controlled through a smartphone app.

To get started, you'll want to make sure your smartphone and Google/Nest device are connected to the same Wi-Fi network.
Next, open the Google Home smartphone app, then tap on the device where you want to change the Wi-Fi settings. Now tap on the Settings icon (which looks like a machine part) in the top-right corner, then tap Wi-Fi -> Forget this network.
You will then be returned to the home screen. Here, you can go through, and need to go through, the Wi-Fi setup process again, and connect the device to your new Wi-Fi network.
However, if you have already set up a new Wi-Fi network — say you have installed a new router and thrown your old one away — you may not be able to connect to the Google/Nest device using the Google Home app. If you run into this problem, which we have experienced ourselves, you can try this next step for troubleshooting, which involves a factory reset of your smart home device.

Troubleshooting: If the smart home device won't connect to the new router
If your smart home device refuses to connect to the new router, you can do a factory reset of the device. This is not as ominous as it sounds, as smart home devices themselves don't hold much information on them — those details are in the app.
To start this option, to perform a factory reset of the product, follow our instructions here, then come back to this article. It should take just a few seconds to reset the device.
Once you have either reset the device or told it to forget your Wi-Fi network, it's time to get it reconnected.
To do this, plug in the Google/Nest device and make sure your smartphone is connected to the new Wi-Fi network, then open the Google Home app.
The app should automatically see your Google or Nest product trying to connect. If the app doesn't see your Google/Nest device, unplug it, wait 10 seconds, then plug it back in and try again.
Next, tap Add in the top-left, then tap 'Set up a device,' followed by 'Set up new devices in your home.' The app will now walk you through the setup process and connect the device to your new Wi-Fi network.Check out The GearBrain, our smart home compatibility checker to see the other compatible products that work with Google Assistant devices.
