If you need to change your Google Home's Wi-Fi network, it's easy to do. Here are the steps:
1. Open the Google Home app on your mobile device.
2. Tap the Devices icon in the upper right corner of the screen.
3. Select your Google Home device from the list that appears.
4. Tap the Settings icon (the gear icon) next to your device name.
5. Scroll down and tap Wi-Fi under Network settings.
6. Tap SCAN FOR NETWORKS and choose your new Wi-Fi network from the list that appears then enter its password when prompted. If you don't see your network listed, make sure it's broadcasting its SSID (network name). You can also try forgetting and re-adding your home Wi-Fi network in the app if needed..
