Switch Your Chromecast to a Different Wi-Fi Network in Four Steps

To change which Wi-Fi network your Chromecast uses, open the Google Home app on your phone, tap the device, select Settings, then Network, and choose "Forget Network" or "Change Wi-Fi Network." Your Chromecast will then prompt you to select a new network and enter the password. The whole process takes about two minutes and does not require a factory reset.

You might need to do this if you changed your router, upgraded your internet plan, moved to a new home, or want to connect to a guest network instead. The steps are the same whether you own a Chromecast, Chromecast with Google TV, or a Chromecast built into another device like a TV or speaker.

Key Takeaways

  • Open Google Home, find your Chromecast device, go to Settings, then Network, and select the option to change or forget your Wi-Fi network.
  • You will need the password for the new network you want to connect to, but you do not need to unplug the device or reset it to factory settings.
  • If your Chromecast cannot find the new network, check that your router is turned on and broadcasting the network name, and that you are within range.
  • Chromecast works with 2.4 GHz and 5 GHz networks, but some older models do not support 5 GHz, so check your device manual if you are switching between band types.

Step-by-Step: Using the Google Home App

Start by opening the Google Home app on your phone or tablet. Make sure your phone is connected to the same Wi-Fi network as your Chromecast, or at least on the same home network. Tap the Chromecast device you want to change — it will show the name you gave it, like "Living Room" or "Bedroom TV."

Once you open the device card, look for the Settings icon (a gear symbol) in the top right corner and tap it. Scroll down to find "Network" and tap that option. You will see the current network name listed. Tap "Forget Network" if you want to remove it entirely, or "Change Wi-Fi Network" if your app shows that button.

Your Chromecast will now scan for available networks and display a list. Find the network you want to connect to and tap it. Enter the Wi-Fi password when prompted — this is the same password you use on your phone or computer to connect to that network. Tap "Connect" and wait for the device to establish the connection, which usually takes 30 to 60 seconds.

What to Do If Your Chromecast Cannot Find the Network

If the network you want does not appear in the list, first check that your router is powered on and that the network name (SSID) is being broadcast. Most routers have a setting to hide the network name; if yours is hidden, you may need to enter the name manually instead of selecting it from the list. Look for an option like "Enter Network Name Manually" or "Other Network" at the bottom of the network list in Google Home.

If you are trying to connect to a 5 GHz network and your Chromecast is an older model, it may not support that band. Original Chromecast devices and some first-generation Chromecast with Google TV models only work on 2.4 GHz. Check your device manual or the product page on Google's support site to confirm which bands your model supports. If your router broadcasts both bands under the same name, try connecting to the 2.4 GHz version instead, which is often labeled with "2.4G" or "-2.4" in the network name.

Make sure you are within range of the router — Chromecast typically needs to be within 30 to 50 feet of the router for a stable connection. If you are at the edge of that range, moving the device closer or repositioning the router may help it detect the network.

Connecting to a Guest Network or Temporary Network

Chromecast can connect to guest networks the same way it connects to your main network. Open Google Home, go to Settings and Network, and select the guest network from the list. Enter its password and wait for the connection to complete. This is useful if you want to keep your Chromecast on a separate network from your computers and phones, or if you are in a temporary location like a hotel or vacation rental.

Keep in mind that if your guest network has restrictions — such as blocking casting from certain devices or limiting bandwidth — those restrictions will explore to your Chromecast. Some hotel and corporate networks block casting entirely, so if you cannot cast after connecting, the network itself may not allow it.

Reconnecting After a Network Change

If you changed your router or your internet service provider gave you a new one, your Chromecast will lose connection automatically. You do not need to do anything — just follow the steps above to connect it to the new network. Your casting history, paired devices, and other settings will remain the same once you reconnect.

If you changed your Wi-Fi password but kept the same network name, your Chromecast will also disconnect. Go to Settings and Network, select your network again, and enter the new password. You do not need to forget the old network first — just select it and enter the updated password.

Troubleshooting Connection Problems After Switching Networks

If your Chromecast connects to the new network but casting does not work, restart the device by unplugging it for 10 seconds and plugging it back in. While it restarts, also restart your router by unplugging it for 10 seconds. This clears temporary connection issues and usually fixes casting problems.

If casting still does not work, check that your phone and Chromecast are on the same network. Open your phone's Wi-Fi settings and confirm it is connected to the same network name as your Chromecast. If your router broadcasts separate 2.4 GHz and 5 GHz networks with different names, make sure both devices are on the same one. Some phones prefer 5 GHz while Chromecast may be on 2.4 GHz, which prevents them from communicating.

If you see an error message like "Device Offline" in Google Home, the Chromecast lost connection to the network. Go back to Settings and Network and reconnect it. If it keeps disconnecting, move the device closer to the router or check whether other devices on that network are also having trouble — if they are, the problem is with your router or internet connection, not the Chromecast.

Frequently Asked Questions

Do I lose my casting history or settings when I change networks?

No. Your Chromecast keeps all its settings, paired devices, and casting history when you switch networks. Only the network connection itself changes. If you factory reset the device, you will lose everything, but straightforward changing the network does not affect any of your data.

Can I connect my Chromecast to a 5 GHz network?

It depends on your model. Chromecast (3rd generation and newer), Chromecast with Google TV, and most Chromecast built into TVs support both 2.4 GHz and 5 GHz. Older models support only 2.4 GHz. Check your device manual or Google's support page for your specific model to confirm which bands it supports.

What if I do not have the Google Home app?

You need the Google Home app to change your Chromecast's network. It is free and available on both Android and iOS. read it from the Google Play Store or Apple App Store, sign in with the Google account you used to set up your Chromecast, and you will see your device listed.

Can I change my Chromecast network without unplugging it?

Yes. You can change the network entirely through the Google Home app without unplugging the device. The only time you need to unplug it is if it stops responding or if you want to perform a full restart to fix a connection problem.

Why does my Chromecast keep disconnecting from the new network?

This usually means the device is at the edge of your router's range or there is interference from other devices. Try moving your Chromecast closer to the router, or move the router to a more central location in your home. If other devices also disconnect frequently, the problem is likely with your router or internet connection, not the Chromecast.
