The fastest way to switch Chromecast to a new network

To change your Chromecast to a different WiFi network, you need to reset it to factory settings, then set it up again on the new network. The process takes about five minutes and requires only your Chromecast device, a TV or monitor, and the Google Home app on your phone.

Chromecast does not have a built-in menu to change networks without resetting. Once it connects to a WiFi network during setup, the only way to move it to a different network is to erase its settings and start over. This is the same process whether you are moving to a new router, changing your WiFi password, or switching to a guest network.

Key Takeaways

  • Resetting your Chromecast erases all settings and network information, which is required to connect to a different WiFi network.
  • You can reset Chromecast using the physical reset button on the device or through the Google Home app.
  • After reset, the device appears as a new Chromecast in the Google Home app and you set it up on your new network from scratch.
  • The entire process — reset, setup, and connection — usually takes five to ten minutes.

How to reset Chromecast using the physical button

The physical reset button is the most direct method. Locate the small reset button on your Chromecast device — it is usually recessed into the body so you cannot press it by accident. On most models, it sits on the side or back of the device near the power cable.

With the Chromecast plugged in and powered on, press and hold the reset button for about 15 seconds. The LED light on the device will turn solid white, then blink orange and white. When the light begins blinking, release the button. The device is now resetting and will restart automatically. This takes about one to two minutes.

Once the light stops blinking and returns to a steady color, the reset is complete. The Chromecast is now in setup mode and ready to connect to a new network.

How to reset Chromecast through the Google Home app

If you cannot locate the physical reset button or prefer to use your phone, you can reset through the Google Home app. Open the app on the same phone you used to set up the Chromecast originally, or any phone that is currently connected to the same WiFi network as the device.

Tap the Chromecast device in the app. At the top right, tap the settings icon (three vertical dots). Scroll down and tap "Factory reset." A confirmation message will appear. Tap "Factory reset" again to confirm. The app will show a message that the device is resetting.

The reset takes one to two minutes. You do not need to stay in the app — you can close it and the reset will continue. Once the reset finishes, the Chromecast will restart and appear as a new device in the Google Home app.

Setting up Chromecast on your new WiFi network

After the reset completes, open the Google Home app and tap the plus icon (+) to add a new device. Select "Set up device" and choose "New device." The app will search for nearby Chromecast devices. When your device appears in the list, tap it to begin setup.

The app will ask you to confirm a four-digit code that appears on your TV screen. This confirms that your phone and Chromecast are communicating. Enter the code, then select your new WiFi network from the list. Enter the WiFi password and tap "Connect."

The Chromecast will connect to the new network and read any necessary updates. This step takes two to five minutes depending on your internet speed. Once the setup is complete, the device will appear in your Google Home app under the new network and is ready to use.

What to do if the Chromecast will not reset

If the reset button does not respond or the device does not reset through the app, try unplugging the Chromecast for 30 seconds, then plugging it back in. Wait for the device to fully power on — the LED should stop blinking — then attempt the reset again.

If the device still will not reset, the physical reset button may be stuck or the device may have a hardware issue. In this case, contact Google Support with your device model and serial number. You can find the serial number on the bottom of the Chromecast or in the Google Home app under device settings.

Connecting to a 5GHz network instead of 2.4GHz

Some routers broadcast both a 5GHz and 2.4GHz network with the same name. During setup, the app will show both options if your router separates them. Chromecast works on both, but 5GHz offers faster speeds if your device is close to the router. If your router combines both frequencies under one name, Chromecast will automatically choose the best one.

If you want to force Chromecast to use a specific frequency, you can rename one of the networks on your router to a different name, then set up Chromecast on that network specifically. Check your router's settings page — usually accessed through a web browser or the router's app — to see if you can separate the networks.

Troubleshooting connection problems after setup

If Chromecast connects during setup but then loses the connection, the issue is usually WiFi signal strength or interference. Move the Chromecast closer to your router or away from other devices that use 2.4GHz, such as microwaves or cordless phones. If the device is far from the router, consider using a WiFi extender.

If the Chromecast connects but the Google Home app does not recognize it, make sure your phone is on the same WiFi network as the device. The app requires both devices to be on the same network to communicate. Restart your phone's WiFi connection and try again.

Frequently Asked Questions

Do I lose my saved shows and preferences when I reset Chromecast?

Chromecast does not store shows or preferences on the device itself — those are saved in your Google account. After you reset and set up the device again, your saved content and preferences will return automatically once you sign in with the same Google account.

Can I change networks without resetting?

No. Chromecast requires a factory reset to connect to a different network. There is no menu option to change networks without erasing the device settings first.

What if I forgot my new WiFi password?

You will need the password to complete setup. Check your router's settings page or contact your internet provider. If you cannot find it, you can reset your router to factory settings, but this will erase all your WiFi settings and you will need to set up the router again from scratch.

How long does the entire process take?

Reset takes one to two minutes, setup takes three to five minutes, and connection takes two to five minutes depending on your internet speed. The entire process usually takes five to ten minutes from start to finish.

Will resetting Chromecast affect other devices on my network?

No. Resetting Chromecast only affects that device. Other phones, computers, and smart devices on your network will not be affected.
