Chromecast updates automatically, but you can check the status and restart the device if an update is stuck

Your Chromecast receives updates over Wi-Fi without you having to do anything. Google pushes these updates to your device in the background, usually overnight when you're not using it. However, if you suspect an update hasn't installed or want to verify your current version, you can check the status manually through the Google Home app and restart the device if needed.

The process takes about five minutes and requires only your phone or tablet and the Google Home app. You don't need a computer, and you won't lose any of your settings or saved information.

Key Takeaways

  • Chromecast updates happen automatically over Wi-Fi, so most users never need to take action.
  • You can check your device's current software version in the Google Home app under device settings.
  • Restarting your Chromecast can help if an update appears to be stuck or if the device isn't responding.
  • A full factory reset erases all your settings and sign-ins, so only use this if the device won't start up at all.
  • Keeping your Wi-Fi connection stable helps updates install smoothly without interruption.

Check your Chromecast version in the Google Home app

Open the Google Home app on your phone or tablet and look for your Chromecast device in the list. Tap and hold the device tile, then tap the gear icon in the top right corner to open settings. Scroll down to "Device information" and you'll see the current software version listed there.

If you want to know whether a newer version exists, you can compare your version number to Google's official release notes on their support pages. However, Google doesn't publish a public schedule for rollouts, so you may not see a newer version available for several weeks after it's released.

Restart your Chromecast if an update seems stuck

If your device hasn't updated in several weeks, the Wi-Fi connection dropped during an update, or the Chromecast isn't responding to commands, a restart often fixes the problem. In the Google Home app, open your device settings the same way: tap and hold the device tile, then tap the gear icon.

Scroll down and tap "System restart." The device will power down and restart, which takes about one to two minutes. During this time, the screen will go dark. Leave the device plugged in and don't unplug it. Once the Chromecast logo appears on your TV again, the restart is complete.

After the restart, check the device information again to see if a new software version has installed. If the version number hasn't changed after 24 hours and your Wi-Fi is working normally, the device may already be on the latest version available for your model.

Make sure your Wi-Fi is stable during updates

Updates read and install over your Wi-Fi network, so a weak or unstable connection can interrupt the process. If your Chromecast is far from your router or in a room with thick walls, move it closer temporarily while updates are installing. You can move it back once the update is complete.

Check that your Wi-Fi password is correct in the Google Home app by opening device settings and tapping "Wi-Fi." If the connection keeps dropping, restart your router by unplugging it for 30 seconds, then plugging it back in. Wait for the router to fully restart before checking your Chromecast again.

Perform a factory reset only as a last resort

If your Chromecast won't turn on, won't connect to Wi-Fi, or is completely unresponsive after a restart, a factory reset may be necessary. This erases all your settings, sign-ins, and paired devices, so only use this option when nothing else works.

To factory reset, unplug the Chromecast from power for 10 seconds, then plug it back in. While it's starting up, press and hold the reset button (a small recessed button on the device itself) for about 15 seconds until the light on the device starts flashing. Release the button and wait for the device to restart. Once it's done, you'll need to set it up again from scratch using the Google Home app.

What to do if your device keeps losing Wi-Fi during updates

If your Chromecast repeatedly disconnects from Wi-Fi during the update process, the problem is usually either distance from the router or interference from other devices. Move the Chromecast closer to your router and away from microwaves, cordless phones, or baby monitors, which can interfere with the 2.4 GHz Wi-Fi band that Chromecast uses.

If you have a dual-band router (2.4 GHz and 5 GHz), make sure your Chromecast is connected to the 2.4 GHz network, not the 5 GHz band. Older Chromecast models only support 2.4 GHz, and even newer models sometimes have trouble staying connected to 5 GHz over longer distances. Check your Wi-Fi settings in the Google Home app to confirm which band you're using.

Understand the difference between software updates and app updates

Your Chromecast device itself receives software updates through the process described above. However, the apps you cast from — like Netflix, YouTube, or Spotify on your phone — update separately through your phone's app store. Keeping both your Chromecast software and your casting apps up to date helps prevent compatibility problems.

If you're having trouble casting from a specific app, check your phone's app store to see if an update is available for that app. Sometimes an older version of a casting app won't work with a newer Chromecast software version, or vice versa.

Frequently Asked Questions

How often does Chromecast get software updates?

Google releases updates roughly every four to eight weeks, though the exact timing varies. Your device may receive the update weeks after Google releases it, depending on your region and device model. There's no way to force an update to arrive sooner.

Will I lose my settings if my Chromecast updates?

No. Software updates preserve all your settings, Wi-Fi connection, and paired devices. You only lose your settings if you perform a factory reset, which is a separate action.

Can I update my Chromecast without Wi-Fi?

No. Your Chromecast must be connected to Wi-Fi to read and install updates. If your device isn't connected to Wi-Fi, reconnect it first through the Google Home app, then wait for the update to install automatically.

What if my Chromecast is stuck on an old software version?

Restart the device through the Google Home app, make sure your Wi-Fi is stable, and wait 24 hours. If it's still not updating, try moving it closer to your router. If the device is several years old, it may have reached the end of its support period and won't receive new updates.

Do I need to do anything while my Chromecast is updating?

No. Leave the device plugged in and connected to Wi-Fi, but you don't need to watch it or keep the app open. The update happens in the background, usually overnight. Avoid unplugging the device during an update, as this can cause the installation to fail.
