The fastest way to switch Chromecast to a different WiFi network

To change the WiFi network your Chromecast uses, you need to reset it to factory settings and set it up again from the beginning. There is no menu inside Chromecast itself where you can pick a new network — the device only stores one WiFi password at a time, and the only way to change it is to erase that password and start over. The whole process takes about five minutes.

You will need the Chromecast device itself, a phone or tablet with the Google Home app installed, and the password for the new WiFi network you want to use. If you are switching to a network in the same home, make sure you have the correct password before you start.

Key Takeaways

  • Chromecast does not have a built-in menu to change WiFi networks — you must factory reset the device and set it up again.
  • Hold the reset button on the back of the Chromecast for 10 to 15 seconds until the light blinks orange, then release it.
  • Open the Google Home app on your phone, tap the plus icon, and select "Set up device" to walk through the WiFi connection step.
  • The device will ask you to select your new network and enter the password during setup.
  • Your old Chromecast name and any custom settings will be erased, but you can rename it during the setup process.

Locate and press the reset button on your Chromecast

The reset button is a small recessed button on the back of the Chromecast device, near the power cable. You will need a straightened paperclip, a ballpoint pen, or a similar thin object to reach it — you cannot press it with your finger.

With the Chromecast plugged in and powered on, press and hold the reset button for 10 to 15 seconds. The light on the front of the device will turn solid orange, then start blinking orange. Once it begins blinking, release the button. The device is now in setup mode and will forget the old WiFi network.

Wait about 30 seconds for the Chromecast to fully restart. The light will continue blinking orange while it prepares for setup.

Open the Google Home app and start setup

On your phone or tablet, open the Google Home app. If you do not have it installed, read it from the Google Play Store (Android) or the Apple App Store (iOS).

Tap the plus icon in the top left corner of the app. Select "Set up device" from the menu. The app will ask whether you want to set up a new device or set up a device in your home. Choose "Set up a new device."

The app will search for nearby devices. Your reset Chromecast should appear in the list within a few seconds. Tap it to begin the connection process.

Select your new WiFi network and enter the password

The app will display a list of WiFi networks in range. Find and tap the name of the network you want to connect to. If the network is hidden (does not appear in the list), you can tap "Can't find your network?" and enter the name manually.

Enter the password for the network. Make sure you type it correctly — WiFi passwords are case-sensitive, and a single wrong character will prevent the connection. If you are unsure about the password, check your router or ask whoever manages the network.

Tap "Next" or "Connect." The Chromecast will attempt to join the network. This usually takes 30 to 60 seconds.

Name your Chromecast and complete setup

Once the connection succeeds, the app will ask you to name the device. You can use the default name (usually "Living Room" or "Bedroom") or type a custom name that helps you identify it — for example, "Kitchen TV" or "Bedroom Speaker." This name will appear in the Google Home app and in casting menus on your phone.

The app will then ask which room the Chromecast is in. Select the correct room or create a new one. This helps organize your devices in the Google Home app if you have multiple Chromecasts.

Tap "Next" to finish setup. The Chromecast light will turn solid white, indicating it is connected and ready to use. You can now cast to it from any compatible app on your phone or computer.

What happens to your old settings and apps

When you factory reset a Chromecast, it erases everything stored on the device — the old WiFi password, the device name, and any preferences you set up. You cannot recover these settings after the reset is complete.

If you had cast apps or services linked to the device (like Netflix, YouTube, or Spotify), you will need to sign into them again the first time you use them. The apps themselves are not deleted, but the device no longer remembers your login information.

If you want to keep the same device name and room assignment, write them down before you reset. Then select the same name and room during the setup process.

Troubleshooting if the Chromecast will not connect

If the Chromecast cannot find your new WiFi network, check that the network is broadcasting its name (SSID). Some routers have an option to hide the network name — if yours does, you can unhide it temporarily in the router settings, or use the "Can't find your network?" option in the Google Home app to enter the name manually.

If the Chromecast connects but then disconnects after a few seconds, the password may be incorrect. Go back to the WiFi selection screen and re-enter the password, paying close attention to uppercase and lowercase letters.

If the app cannot find the Chromecast device at all, make sure your phone is connected to the same WiFi network (or to the same home network via a different band, like 5 GHz). The phone and Chromecast need to be on the same network to communicate during setup. You can also try moving the Chromecast closer to the router temporarily, then move it back once setup is complete.

Frequently Asked Questions

Can I change the WiFi network without resetting the Chromecast?

No. Chromecast does not have a menu option to change networks without resetting. The device stores only one WiFi password at a time, and the only way to change it is to erase the device and set it up again with the new network information.

Will I lose my saved shows or watch history?

No. Your watch history and saved shows are stored in your Google account, not on the Chromecast itself. Once you sign back into your apps after the reset, your history and saved content will reappear. The Chromecast is just a receiver — it does not store your personal data.

What if I forget the password to my new WiFi network?

You can find your WiFi password by logging into your router's settings page. On most home routers, you can access this by typing the router's IP address (usually 192.168.1.1) into a web browser. Look for a section labeled "Wireless" or "WiFi" to find the password. If you do not know the router password, contact your internet provider or the person who set up the network.

Can I use a 5 GHz WiFi network instead of 2.4 GHz?

Yes. Most Chromecasts support both 2.4 GHz and 5 GHz networks. During setup, the app will show you all available networks in range, including both bands. Select whichever one you prefer. If your router broadcasts both bands under the same name, the Chromecast will automatically choose the best one.

How long does the setup process take?

The entire process — from pressing the reset button to completing setup in the Google Home app — usually takes 5 to 10 minutes. The longest part is waiting for the Chromecast to restart and connect to the new network, which can take 1 to 2 minutes.
