How to Fix It When Google Home Can't Find Chromecast

Troubleshooting this common connectivity issue

If you own a Chromecast, there are times when you may discover that Google Home can't find the Chromecast on your network.

This problem takes different forms:

  • When first setting up your Chromecast, you can't connect to the device from your mobile phone.
  • Even after you've set up a Chromecast device properly, you may not see the Chromecast device show up in your Google Home app.
  • There may be times when only some devices can't find your Chromecast, while other devices can.

If your Google Home app can't connect to Chromecast, then your Google Home itself won't be able to make the connection.

Use the following steps to troubleshoot your issue and get both your Home app and the Google Home device connected to Chromecast again.

When you set up a Chromecast, you need to connect to the Chromecast to set up the device on your home Wi-Fi network. Once connected, devices must connect to the Chromecast by connecting to the home Wi-Fi network first.

Connection problems can occur at every step of that process, and for different reasons.

How to Fix It When Google Home Can't Find Chromecast

If you can't make the connection between your Google Home device and your Chromecast device, there are a few things you can try to get things working again.

  1. Follow the steps to set up your new Chromecast device. If your Google Home app can't find the Chromecast device, make sure the Chromecast device is powered up and plugged into the HDMI port on your TV. Also make sure your TV is turned on and set to the correct HDMI port.

    You'll know you've selected the correct HDMI port when you see the Chromecast home screen and background on your TV screen.

  2. If your Google Home still can't find Chromecast during setup, make sure your mobile device is connected to the same Wi-Fi network you intend to connect your Chromecast device to.

    A common mistake that occurs during Chromecast setup is not enabling Wi-Fi on the mobile device where Google Home is installed. Once connected to Wi-Fi, your mobile device should detect the Chromecast device and launch the setup wizard where you'll select your home Wi-Fi network and password.

  3. If both the Chromecast and your mobile device are having Wi-Fi connection issues, you could have problems with your Wi-Fi network or router. Troubleshoot those Wi-Fi connection problems before moving on to the next steps.

  4. If your mobile device still can't connect to the Chromecast, make sure your device supports a 5 GHz Wi-Fi connection. This is required for Google Home to find Chromecast. If your device doesn't support it, install Google Home on a different mobile device and try the setup again.

  5. Make sure your Google Home app can connect to the network. To do this, check that your Android is connected to the Wi-Fi network. If you're using an iPhone, ensure it's connected to Wi-Fi. Once your device is connected, make sure your Google Home app can connect to the Wi-Fi network.

  6. If you've previously had your Chromecast working properly, but Google Home still can't find the Chromecast, make sure your Chromecast is still connected to your Wi-Fi network. You can verify this by checking the Chromecast screen on your TV. You should see your Wi-Fi network name and current type displayed on the screen. If you don't see this, perform a hard reset on your Chromecast device.

  7. Finally, if your Google Home app and your Chromecast are both connecting to Wi-Fi, and you can cast video from the Google Home app to Chromecast, then the problem might be with your Google Home Wi-Fi connection itself. Walk through the troubleshooting steps to fix your Google Home's Wi-Fi connection.

Once you've re-established the connection between your Google Home and Chromecast, make sure to update your Chromecast. This will reduce the chances of future connection problems.
