Change your Chromecast's network in the Google Home app

To move your Chromecast to a different Wi-Fi network, open the Google Home app on your phone or tablet, find your Chromecast device in the list, tap the settings icon (gear symbol), then select Wi-Fi. The app will scan for available networks and let you choose a new one. Enter the password for that network, and your Chromecast will disconnect from the old network and connect to the new one.

The process takes about one to two minutes. Your Chromecast will restart during the switch, so you may see it briefly unavailable in the app—this is normal. Once the light on the device stops blinking, the connection is complete.

If you do not have the Google Home app installed, read it from the Google Play Store (Android) or the App Store (iOS). You must be on the same Wi-Fi network as your Chromecast to change its settings, so stay connected to your old network until the switch is finished.

Key Takeaways

  • Open Google Home, find your Chromecast, tap settings, and select Wi-Fi to see available networks.
  • Your Chromecast must be connected to a network before you can change it—you cannot set it up on a new network from scratch using the app alone.
  • The device will restart during the switch, and the light will blink until the new connection is established.
  • If your Chromecast loses power or the connection fails partway through, you may need to factory reset it and set it up again from the beginning.

What happens if the password is wrong

If you enter an incorrect password, the Chromecast will attempt to connect, fail, and return to the Wi-Fi selection screen. You will see an error message asking you to try again. straightforward re-enter the correct password and tap connect.

If you do not know the password to your new network, check your router's label (usually on the bottom or back), or log into your router's admin panel from a computer or phone on that network. Your router's manual or the manufacturer's website will show you how to find the password if you have changed it from the default.

Switching between 2.4 GHz and 5 GHz networks

Some routers broadcast both a 2.4 GHz and a 5 GHz network with the same name (called dual-band). When you select that network name in Google Home, your Chromecast may connect to either one. If you want to force it to use a specific band, you will need to separate them in your router settings so they have different names (SSIDs).

Most Chromecast models work better on 2.4 GHz if you are far from the router or have walls between them, because 2.4 GHz travels farther. The 5 GHz band is faster but does not travel as far. If your Chromecast keeps dropping connection, try switching it to 2.4 GHz by renaming that band in your router and reconnecting.

When you need to factory reset your Chromecast

If the app cannot find your Chromecast, or if the connection fails partway through and the device becomes unresponsive, a factory reset may be necessary. Locate the small reset button on the device itself (usually on the back or bottom), hold it down for about 10 seconds until the light turns orange, then release. The Chromecast will restart and return to its original setup state.

After a factory reset, you will need to set up the device again from the beginning using Google Home. This means choosing a network, entering the password, and naming the device. A reset erases all settings but does not delete anything from your phone or account.

Moving your Chromecast to a guest or temporary network

If you are connecting to a guest network, a hotel Wi-Fi, or a temporary hotspot, the process is the same: select the network name in Google Home and enter the password. Some public networks require you to open a browser and accept terms before devices can connect. If your Chromecast connects but does not work, try opening a web browser on your phone and visiting any website—you may see a login page that needs your acceptance first.

Keep in mind that if you move your Chromecast to a network without internet access, or to a network that blocks the ports Chromecast uses, the device will connect but casting will not work. If casting fails on a new network, contact the network administrator or try a different network to rule out a connection problem.

Troubleshooting a stuck or slow connection

If your Chromecast connects to the new network but casting is slow or keeps stopping, the issue may be signal strength, interference, or network congestion rather than the Chromecast itself. Move your router closer to the Chromecast, or move the Chromecast closer to the router. If other devices on the network work fine, restart your Chromecast by unplugging it for 10 seconds and plugging it back in.

If restarting does not help, try changing the Wi-Fi channel on your router. Routers on 2.4 GHz often interfere with each other if they are set to the same channel. Your router's admin panel (usually accessed by typing the router's IP address into a browser) will let you change the channel. Channels 1, 6, and 11 are the standard non-overlapping options on 2.4 GHz.

Frequently Asked Questions

Do I lose my saved apps and settings when I change networks?

No. Changing the Wi-Fi network does not erase apps, saved logins, or any settings on your Chromecast. Your Google account and all preferences stay the same. Only the network connection itself changes.

Can I change the network if my Chromecast is already set up?

Yes. As long as your Chromecast is powered on and currently connected to a network (even if it is the old one), you can change it to a new network using Google Home. You do not need to reset it first.

What if Google Home cannot find my Chromecast?

Make sure your phone is connected to the same network as your Chromecast. If it is not, you cannot access the device's settings. If your phone is on the same network and Google Home still does not see it, restart both your Chromecast and your phone, then try again.

Can I change the network from a computer instead of a phone?

No. The Wi-Fi settings for Chromecast are only available in the mobile Google Home app, not in the web version. You must use a phone or tablet running Android or iOS to change the network.

Will my Chromecast work if I move it to a 5 GHz only network?

Most Chromecast models support 5 GHz, but some older ones do not. Check your device's specifications on Google's support site. If your model does not support 5 GHz, you will need to use a 2.4 GHz network or a dual-band router that broadcasts both.
