The fastest way to switch Chromecast to a different WiFi network

To change the WiFi network your Chromecast uses, you need to reset the device to factory settings and set it up again from the beginning. There is no menu inside the Chromecast itself to change networks — you must go through the initial setup process a second time using the Google Home app on your phone or tablet.

The whole process takes about 10 minutes. You will need the Chromecast plugged in, your phone or tablet nearby, and the password for the new WiFi network you want to use.

Key Takeaways

  • Chromecast does not have a settings menu to change WiFi — you must factory reset it and run setup again.
  • Hold the reset button on the back of the device for 10 to 15 seconds until the light blinks orange, then release.
  • Open the Google Home app on your phone, tap the plus icon, and select "Set up device" to reconnect to your new network.
  • The device will ask you to select your new WiFi network and enter the password before it finishes setup.
  • If your Chromecast is built into a TV, look for a factory reset option in the TV's settings menu instead of using the physical button.

Locating and pressing the reset button

On the back or bottom of your Chromecast, you will find a small recessed button labeled "Reset." It is usually next to the power cable connection. You may need a straightened paperclip or a ballpoint pen to reach it — the button is intentionally small so you do not press it by accident.

Press and hold that button for 10 to 15 seconds without releasing. The LED light on the device will turn solid orange, then blink orange. Once it starts blinking, you can let go. The device is now erasing its settings and returning to factory defaults. This takes another 30 seconds or so — you will see the light change again when it is finished.

If your Chromecast is built into a TV (sometimes called Chromecast built-in), the physical reset button may not be accessible. Instead, go into your TV's settings menu, find the "System" or "About" section, and look for a "Factory reset" or "Reset to defaults" option. The exact path varies by TV brand.

Opening Google Home and starting setup

On your phone or tablet, open the Google Home app. If you do not have it yet, read it from the Google Play Store (Android) or the App Store (iPhone and iPad).

Tap the plus icon (+) in the top left corner. A menu will appear with options including "Set up device." Tap that option. The app will ask whether you want to set up a new device or set up a device already in your home — choose "Set up a new device."

The app will then search for nearby devices. Your reset Chromecast should appear in the list within 10 to 20 seconds. Tap it to begin the setup process.

Selecting your new WiFi network

The app will ask you to confirm the room where the Chromecast is located (kitchen, bedroom, living room, and so on). Select the correct room, then tap "Next."

Next, the app will show you a list of WiFi networks in range. Find and tap the network you want to connect to. If your network does not appear, make sure the router is powered on and within range. You can also scroll down to see more networks, or tap "Can't find your network?" to enter the network name manually if it is hidden.

After you select the network, the app will ask for the WiFi password. Type it in carefully — passwords are case-sensitive, so uppercase and lowercase letters matter. Tap "Next" when you are done.

Completing the setup and testing the connection

The Chromecast will now connect to your new network. This usually takes 30 to 60 seconds. You will see a progress screen while it connects. Do not unplug the device or close the app during this time.

Once the connection is successful, the app will ask you to name the device (you can keep the default name or change it to something like "Living Room TV" or "Bedroom Chromecast"). You can also choose whether to let Google save your WiFi password for faster setup on future devices — this is optional.

Tap "Finish" when you are done. The Chromecast is now set up on your new network. Test it by casting something from your phone — open YouTube, Netflix, or another app that supports Chromecast, and tap the cast icon to make sure the device appears and works.

What to do if the Chromecast will not connect to the new network

If the device fails to connect after you enter the password, the most common cause is an incorrect password. Go back and try entering it again, paying close attention to capital letters and special characters. If you are not sure of the password, check your router's label or log into your router's admin page from a computer to see the network name and password.

If the network does not appear in the list at all, move the Chromecast closer to the router temporarily. Some older Chromecast models only support 2.4 GHz WiFi networks, not 5 GHz. If your router broadcasts both, try connecting to the 2.4 GHz network instead — it will usually have a name ending in "-2.4G" or "-24G."

If the device still will not connect after a second reset attempt, unplug it for 30 seconds, plug it back in, and try the reset and setup process again from the beginning.

Switching back to your old network later

If you ever want to move the Chromecast back to your original WiFi network, follow the same reset and setup process. You do not need to do anything special — just reset, set up again, and select your original network when prompted.

You can also set up the same Chromecast on multiple networks if you move it between locations (like between home and a vacation house). Each time you move it, reset and set it up on the new network. The device will only be connected to one network at a time.

Frequently Asked Questions

Can I change the WiFi network without resetting the Chromecast?

No. Chromecast does not have a built-in menu to change networks. The only way to switch to a different network is to factory reset the device and run the setup process again using the Google Home app.

What happens to my saved apps and settings when I reset?

Everything is erased — apps, settings, and any customization you made. However, once you sign back into your Google account during setup, your apps and preferences will read again automatically. You will not lose anything permanently.

How long does the whole process take?

From pressing the reset button to finishing setup is usually 10 to 15 minutes. Most of that time is waiting for the device to reset and connect to the new network. The actual steps you perform take only a few minutes.

Do I need to be on the same WiFi network as my Chromecast to cast to it?

Yes. Your phone and the Chromecast must be on the same WiFi network for casting to work. If you are on a different network, you will not see the Chromecast in the cast menu.

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

If you set up the router yourself, check the label on the back or bottom of the router — the default password is usually printed there. If you changed the password and forgot it, you can reset the router to factory defaults by holding the reset button for 10 to 15 seconds, but this will erase all your WiFi settings. Alternatively, log into the router from a computer connected by ethernet cable to change the password.
