The fastest way to switch Chromecast to a different WiFi network

To change your Chromecast's WiFi connection, open the Google Home app on your phone, tap the device, select the gear icon for settings, choose "WiFi," and then select a new network from the list. The whole process takes about two minutes. Your Chromecast will disconnect from the old network and reconnect to the new one without losing any of your saved apps or settings.

You do not need to unplug the device or reset it to factory settings. The change happens through the app while your Chromecast stays plugged in and powered on.

Key Takeaways

  • Open Google Home, tap your Chromecast device, select settings, and choose WiFi to see available networks.
  • Your Chromecast must already be connected to a WiFi network (the old one) before you can change it through the app.
  • If your Chromecast is not responding in the app, restart it by unplugging it for 30 seconds, then plug it back in.
  • If you cannot find your new network in the list, make sure your phone is connected to that network and the network is broadcasting its name.

Step-by-step instructions for changing the network

Start by opening the Google Home app on the phone or tablet you use to control your Chromecast. Make sure you are signed into the same Google account you used to set up the device.

Tap and hold the Chromecast device tile. A menu will appear at the bottom of the screen. Tap the gear icon in the top right corner to open settings. Scroll down and tap "WiFi." The app will show you the network your Chromecast is currently connected to, plus a list of other networks in range. Tap the network you want to switch to, enter the password if it is password-protected, and tap "Connect." Wait about 30 seconds for the connection to complete.

Once the app shows "Connected," your Chromecast is now on the new network. You can close the app and start casting to it right away.

What to do if your Chromecast will not appear in the app

If you open Google Home and your Chromecast does not show up, or if it shows up but is marked as offline, the device has lost connection to WiFi. In this case, you cannot change the network through the app because the app cannot reach the device.

Unplug the Chromecast from power for 30 seconds, then plug it back in. Wait about two minutes for it to restart and reconnect to the old network. Once it appears as "Connected" in the Google Home app, follow the steps above to switch to the new network. If it still does not appear after restarting, move the Chromecast closer to your router temporarily and try again.

When your new network does not appear in the list

If you are looking for a network and it is not showing up in the list on your Chromecast, the most common reason is that the network is not broadcasting its name. Some routers have a setting to hide the network name (SSID). If this is the case, you will need to type the network name manually instead of selecting it from the list.

In the WiFi settings screen, look for an option that says "Add network" or "Other networks." Tap it, type the exact name of your network, select the security type (usually WPA2 or WPA3), enter the password, and tap "Connect." Make sure you spell the network name exactly as it appears in your router settings.

Switching between networks you use regularly

If you move your Chromecast between locations — for example, from your home to a vacation house — you can add multiple networks to the device. The next time you power it on near one of those networks, it will automatically connect to whichever one is in range.

To add a second network without removing the first, open Google Home, go to the device settings, tap "WiFi," and select a different network. Your Chromecast will remember both networks. When you travel, just plug in the device and it will find the network it knows.

What happens to your apps and settings when you change networks

Changing the WiFi network does not erase anything on your Chromecast. Your apps, your Google account login, your display settings, and any custom backgrounds you have set will all stay exactly as they are. The device only disconnects from the old internet connection and connects to the new one.

The only time you lose settings is if you perform a factory reset, which you do not need to do to change networks. A factory reset erases everything and returns the device to the state it was in when you first took it out of the box.

Troubleshooting a slow or dropped connection after switching

If your Chromecast connects to the new network but casting is slow or the connection drops frequently, the issue is usually distance or interference. Move the Chromecast closer to your router. If that is not possible, check whether your router is broadcasting on both the 2.4 GHz and 5 GHz bands. Chromecast works on both, but 2.4 GHz has longer range and is more stable in homes with thick walls or multiple floors.

You can also restart the Chromecast by unplugging it for 30 seconds. Sometimes a fresh connection to the new network clears up temporary glitches. If the problem continues, restart your router as well by unplugging it for 30 seconds.

Frequently Asked Questions

Do I need to reset my Chromecast to change the WiFi network?

No. A factory reset erases all your settings and apps. You only need to open the Google Home app, go to WiFi settings, and select a new network. The change takes about two minutes and keeps everything else on your device intact.

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

You will need to find the password before you can connect. Check your router's label (usually on the bottom or back), or log into your router's admin page from a computer or phone to view or reset the password. Once you have it, enter it in the Chromecast WiFi settings screen.

Can I change the WiFi network without using the Google Home app?

No. The Google Home app is the only way to change networks on a Chromecast that is already set up. If your Chromecast is completely offline and you cannot reach it through the app, you will need to factory reset it and set it up again from scratch on the new network.

Will my Chromecast automatically switch back to the old network if I move it?

Yes. If your Chromecast has been connected to multiple networks, it will automatically connect to whichever one is in range when you power it on. If you want to prevent this, you can remove the old network from the device's memory by going to WiFi settings and selecting "Forget" next to that network's name.
