A Chromecast is an excellent addition to any home entertainment system. These allow you to stream content from Netflix, Hulu, or even mirror your smartphone display when everything is working correctly. When your Chromecast isn’t working, it can be a frustrating experience that quickly kills the party. We’ve put together a list of ways to fix your Chromecast when it stops working. Follow it, and you’ll be back streaming in no time!

Editor’s note: All steps in this article were assembled using a Google Pixel 7 running Android 13, a custom PC running Windows 11, a Chromecast Ultra, and a Chromecast with Google TV. We also used an Apple iPhone 12 Mini running iOS 17 to ensure the steps are the same as in Android. We will add iOS-specific instructions when they differ.

Restart your Chromecast device

When your Chromecast isn’t working, you should first try rebooting the device. The easiest way to do this is the tried and true method of unplugging it, waiting for a minute or so, and then plugging it back in. Give it a few minutes to start up, then try casting to your Chromecast again.

If you’re not a fan of unplugging devices and still have access to the settings, you can also reboot using software.

How to restart a Chromecast:

  1. Open the Google Home app on your smartphone. Make sure you’re using the same Google account and Wi-Fi network.
  2. Find your Chromecast. Tap and hold on to its tile.
  3. Tap on the Gear icon.
  4. Select the three-dot menu button.
  5. Hit Reboot.
  6. Confirm by hitting OK.

How to restart a Chromecast with Google TV:

  1. Using your Chromecast remote, highlight and select the Settings gear icon.
  2. Go into System.
  3. Pick Restart.
  4. Confirm by selecting Restart.

Check your internet connection

Your internet connection might be the issue. Check other devices and see if they’re connected to the internet. However, the router might still be the issue if everything else seems to be operating correctly.

We won’t pretend to be technicians, but we’ve found that often a simple power cycle can work miracles. Unplug your router for about a minute, then plug it back in. Once your router has booted, try your connection again. Many routers also come with a reset button, which you can also use if you have one.

Another potential cause of poor connectivity is the location of the Chromecast behind your television. The device is nicely hidden away, so it might not receive enough Wi-Fi juice to stream your favorite shows. You can use the included HDMI extender to have the Chromecast stick out more. Or you can try moving the Chromecast closer to your router. If you have a Chromecast Ultra, you have the extra option of connecting an ethernet cable to the power brick.

Connect the Chromecast and other devices to the same network

This is a widespread issue! Sometimes, we forget that our phones aren’t connected to the same network as the Chromecast. Cast works best when all devices are on the same network. Try to join the same Wi-Fi network as the Chromecast and see if that fixes the problem.

This is especially a thing to keep in mind now that Google has removed Guest Mode from Chromecast devices. Guest Mode allowed you to stream to Chromecast devices without being connected to the same Wi-Fi network, as long as you were close to it.

If you’re not sure which Wi-Fi connection your Chromecast is connected to, you can check it in the Google Home app.

How to check which Wi-Fi network my Chromecast is connected to:

  1. On your phone, launch the Google Home app.
  2. Under the Devices tab, tap and hold onto your Chromecast device.
  3. Hit the Settings gear icon.
  4. Tap on Device information.
  5. You’ll see the network name under Wi-Fi.

How to check which Wi-Fi network my Chromecast with Google TV is connected to:

  1. Using your remote, highlight and select the Settings gear icon.
  2. You will see your network name under Network & Internet.

Reboot your computer or smartphone

Like always, many problems are solved with a quick reboot. Restart the phone, tablet, or computer you’re trying to cast from. If your Chromecast isn’t working after a fresh reboot, move on to the next fix on the list. You can also stop casting on your Chromecast, then try to cast again after a minute or two.

How to restart an Android phone:

  1. Simultaneously press the side and volume up buttons.
  2. Hit Restart.

Restart an iOS phone:

  1. Press and hold the side and volume up buttons until the power screen appears.
  2. Slide the power slider that reads slide to power off.
  3. When the device is off, press and hold the side button until the device turns on.

How to restart a Windows computer:

  1. Left-click on the Windows button.
  2. Pick the Power button.

Update your Chrome browser or device

Perform a factory data reset on your Chromecast

If all else fails and your Chromecast still isn’t working, it’s time to perform a factory data reset. The good news is you won’t lose any data, but you will have to set up your Chromecast again from scratch.

Without unplugging your Chromecast, hold down the button on the back of the device for at least 25 seconds. Your TV screen will eventually go blank, and the reset process will begin. Once finished, you can start the setup process again. If possible, it’s best to use a different phone than you used the first time. This will rule out any device-related issues.

Additionally, you can factory reset your Chromecast using the Google Home app. Here’s the process, but remember this method doesn’t work for Chromecast with Google TV devices. We’ll also show you how to factory reset a Chromecast with Google TV.

How to perform a factory reset on a Chromecast:

  1. Open the Google Home app on your smartphone. Make sure you’re using the same Google account and Wi-Fi network.
  2. Find your Chromecast device and select it.
  3. Tap on the Gear icon.
  4. Hit the three-dot menu button.
  5. Select Factory reset.
  6. Confirm by hitting Factory reset.

  6. Select Erase everything.

Give Chromecast more power

If your Chromecast is turning off suddenly, blacking out periodically, or restarting frequently, the problem is probably related to its power supply.

Chromecasts are powered by the USB cable in the box, and many television sets have USB ports conveniently located next to the HDMI ports. It might seem like a cable-saving measure to plug the USB cable into your TV, but this can cause power issues.

Turning off your TV cuts power to the USB ports, causing it to reboot every time you turn off the TV. Even worse, cheaper TV sets may have poorly configured or unstable USB ports. Or maybe the TV doesn’t provide enough power from its USB ports.

Unplugging your Chromecast USB cable from your TV and plugging it into the wall charger supplied should remedy this issue. If you no longer have the included wall charger, try an old phone charger or buy a third-party charger.
