The fastest way to reconnect your Chromecast to a different network
To change your Chromecast's WiFi connection, you need to factory reset the device and set it up again from the beginning. There is no menu inside the Chromecast itself where you can straightforward pick a new network — the device stores its WiFi password in a way that requires a full reset to change it. The process takes about five minutes and uses the Google Home app on your phone.
The steps are: hold the reset button on the back of your Chromecast for 15 seconds until the light blinks orange, wait for it to cool down, open the Google Home app, tap the plus icon to add a device, select Chromecast, choose your new WiFi network, and enter the password. Your Chromecast will then connect to the new network and be ready to use.
Key Takeaways
- Chromecast does not have a settings menu to change WiFi — you must factory reset the device and set it up again.
- Press and hold the reset button on the back of the device for 15 seconds until the light turns orange, then release.
- Use the Google Home app on your phone to complete the setup and connect to your new WiFi network.
- The entire process takes about five minutes and does not require a computer or any special tools.
What the reset button does and where to find it
The reset button on a Chromecast is a small recessed button on the back or bottom of the device, depending on which model you own. On the standard Chromecast (the round puck), it is on the flat back. On Chromecast with Google TV (the larger rectangular device), it is on the bottom near the power cable. You will need a straightened paperclip or a ballpoint pen to press it, since the button sits inside a small hole to prevent accidental presses.
When you press and hold this button for 15 seconds, the Chromecast erases all stored information — including the WiFi password, paired devices, and any settings you have changed. The light on the device will blink orange to signal that the reset is happening. Once you release the button, wait about 30 seconds for the device to finish the reset before you unplug it or move on to the next step.
Setting up your Chromecast on the new network
After the reset is complete, open the Google Home app on your phone or tablet. Tap the plus icon in the top left corner and select "Set up device." Choose "Set up a new device" and then "Chromecast." The app will search for nearby Chromecast devices and should find yours within a few seconds. If it does not appear, make sure your phone is on the same WiFi network you want to connect the Chromecast to, or try moving your phone closer to the device.
Once the app finds your Chromecast, it will ask you to confirm a code that appears on your TV screen. This code matches what the app shows, and confirming it proves you are setting up your own device. After you confirm the code, the app will ask you to select your WiFi network from a list and enter the password. Type the password carefully — Chromecast will not connect if the password is wrong, and you will have to reset and start over.
The app will then connect your Chromecast to the network and read any necessary updates. This can take a few minutes. Once it finishes, your Chromecast is ready to use on the new network. Any devices on that network can now cast to it.
Why Chromecast does not let you change WiFi without resetting
Chromecast stores your WiFi password in encrypted form on the device itself, and there is no built-in way to edit or delete just that one piece of information. The device does not have a web interface or a settings app where you can log in and change the network. Google designed it this way to keep the setup straightforward for most users — you plug it in, set it up once, and it works.
The trade-off is that if you move to a new house, switch internet providers, change your WiFi password, or want to use a different network, you have to reset the device. This is by design and applies to all Chromecast models, including the older versions and Chromecast with Google TV.
What to do if your Chromecast will not connect after reset
If the app finds your Chromecast but the connection fails after you enter the password, the most common cause is a typo in the WiFi password. Double-check that you entered it correctly — passwords are case-sensitive, and spaces or special characters must match exactly. If you are not sure of the password, check your router or your internet provider's paperwork.
If the app cannot find your Chromecast at all after the reset, make sure your phone is connected to the WiFi network you want to use. The Google Home app needs to be on the same network to find the device. Also check that your WiFi network is not hidden — if it is, the app will ask you to type the network name manually instead of selecting it from a list. If you still cannot find the device, try moving your phone closer to the Chromecast and waiting a full minute before trying again.
If your Chromecast is very old (more than five years), it may not support your WiFi network's security settings. Older models sometimes have trouble with WPA3 encryption, which newer routers use by default. In that case, you may need to change your router's settings to use WPA2 instead, or consider replacing the device.
Reconnecting your devices after the reset
After your Chromecast is set up on the new network, any phone, tablet, or computer on that same network can cast to it. You do not need to pair devices individually — casting works automatically once the Chromecast is connected. If you use Google Home speakers or displays, they will automatically discover the new Chromecast and add it to your home setup in the Google Home app.
If you had created any routines or automations in the Google Home app that involved this Chromecast, you may need to update them. Open the Google Home app, find the Chromecast in your device list, and check any routines that reference it to make sure they still work as expected.
Frequently Asked Questions
Do I lose anything when I factory reset my Chromecast?
Yes. The reset erases the WiFi password, any paired Google Home devices, and any custom settings you changed. It does not affect your Google account or any shows or movies you have watched — those are stored in your Google account, not on the device. Once you set up the Chromecast again, your account will sync and you can pick up where you left off.
Can I change the WiFi password without resetting the Chromecast?
No. If you change your WiFi password but want to keep the same network name, your Chromecast will lose connection and you will have to reset it and set it up again with the new password. If you are planning to change your WiFi password, it is easier to do that first, then reset the Chromecast and set it up with the new password in one step.
How long does the setup take?
The entire process — reset, app setup, and connection — usually takes about five minutes. If your internet is slow or your Chromecast needs to read a large update, it may take up to ten minutes. The longest part is usually waiting for the device to read and install updates after it first connects to the network.
What if I do not have the Google Home app?
You need the Google Home app to set up a Chromecast on a new network. read it from the Google Play Store on Android or the App Store on iPhone. It is free and made by Google. You will need a Google account to use it, but you do not need to pay for anything.
