How to change your Chromecast's WiFi connection
To change your Chromecast to a different WiFi network, you need to reset it to factory settings and set it up again from the beginning. Chromecast does not have a built-in menu to switch networks without resetting — it stores one WiFi connection at a time, and changing that connection requires you to go through the initial setup process a second time.
The fastest way is to use the Google Home app on your phone or tablet. You will need the Chromecast plugged in, the device you are using to set it up, and the password for the new WiFi network. The whole process takes about five minutes.
Key Takeaways
- Chromecast must be reset to factory settings before it can connect to a different WiFi network — there is no direct "change network" option in the settings.
- Use the Google Home app on your phone or tablet to reset and reconnect your Chromecast; you will need the new WiFi password.
- Your Chromecast must be powered on and within range of the new WiFi network during setup.
- After reconnection, any apps or services that were casting to your old network will need to be told to cast to the Chromecast again.
Reset your Chromecast using the Google Home app
Open the Google Home app on your phone or tablet. Tap the device icon in the top right corner, then select your Chromecast from the list of devices. If you do not see it listed, make sure your phone is connected to the same WiFi network the Chromecast is currently using.
Tap the three-dot menu icon next to your Chromecast's name. Scroll down and tap "Factory reset." A confirmation message will appear — tap "Factory reset" again. The Chromecast will restart and return to its original setup state. This takes about one to two minutes.
Set up your Chromecast on the new WiFi network
Once the Chromecast has reset, the Google Home app will prompt you to set it up. Tap "Set up device" and choose "Set up a new device." Select your home and room location, then follow the on-screen steps.
When the app asks you to choose a WiFi network, select your new network from the list and enter the password. The Chromecast will connect and verify the connection. Once it shows a green checkmark, the setup is complete and your Chromecast is now on the new network.
What to do if your Chromecast does not appear in Google Home
If the Chromecast is not showing up in the Google Home app during setup, make sure your phone is connected to the same WiFi network. The app needs to communicate with the Chromecast over the network to complete setup.
If you are setting up a Chromecast for the first time on a new network, it may take 30 seconds to a minute to appear in the app after you plug it in. If it still does not show after two minutes, unplug the Chromecast, wait 10 seconds, and plug it back in. Then open the Google Home app again and try the setup process once more.
Reconnect your casting apps after the network change
After your Chromecast is on the new network, any apps you use to cast — like YouTube, Netflix, Spotify, or Chrome — will need to be told to cast to it again. Open each app, tap the cast icon, and select your Chromecast from the list of available devices.
If an app does not show your Chromecast in the cast menu, make sure your phone and the Chromecast are on the same WiFi network. Apps can only see and connect to Chromecasts on the same network they are using.
Chromecast setup on a 5GHz network
Some routers broadcast two WiFi networks: one at 2.4GHz and one at 5GHz. Chromecast works on both, but 2.4GHz networks have better range and are more stable for most homes. If your router has separate network names for each band, choose the 2.4GHz network during setup unless you are very close to the router.
If your router combines both bands under one network name (called "band steering"), your Chromecast will automatically connect to whichever band works best in your location. You do not need to do anything — just enter the network password as usual.
Troubleshooting a stuck or unresponsive Chromecast
If your Chromecast is not responding during setup or seems frozen, unplug it from power for 30 seconds, then plug it back in. Wait for the light on the device to stop blinking before trying again.
If the Chromecast still will not reset or connect after a restart, try moving it closer to your router temporarily during setup. Once it is connected to the new network, you can move it back to its normal location. Weak signal during the initial connection can cause setup to fail or hang.
Frequently Asked Questions
Do I lose my apps or settings when I reset my Chromecast?
Yes. Resetting returns the Chromecast to factory settings, so any customization is erased. However, Chromecast itself does not store apps — it only receives video and audio from your phone, tablet, or computer. Once you reconnect it to your new network, you can cast from the same apps you used before.
Can I change WiFi networks without resetting?
No. Chromecast does not have a menu option to change networks without resetting. The only way to connect to a different network is to factory reset and set it up again through the Google Home app.
What if I forget the password to my new WiFi network?
You will need the correct password to complete setup. Check your router's label on the back or bottom — it usually lists the network name and password. If you changed the password and do not remember it, you can reset your router to factory settings, but that will erase all your WiFi settings.
How long does it take to change my Chromecast to a new network?
The entire process — reset, setup, and reconnection — takes about five to ten minutes. Most of that time is the Chromecast restarting and connecting to the new network. The actual steps you perform take less than two minutes.
Will my Chromecast work on a guest WiFi network?
Yes, Chromecast can connect to a guest network the same way it connects to any other WiFi network. During setup, select the guest network from the list and enter its password. Keep in mind that if the guest network is on a separate band or has different settings, casting performance may vary.
