Reset your Chromecast's WiFi by unplugging it for 30 seconds, then reconnecting it to your network through the Google Home app

When your Chromecast stops connecting to WiFi or connects but won't stream, a reset usually fixes it. The simplest reset is a power reset: unplug the Chromecast from power for 30 seconds, plug it back in, and wait for the light to stop blinking. Once it stabilizes, open the Google Home app on your phone, tap the Chromecast device, and go through the WiFi setup again as if it were new.

If that does not work, you can perform a factory reset that wipes all settings and returns the device to its original state. This erases your WiFi password and any other configuration, so you will set it up from scratch. A factory reset is worth trying if a power reset does not restore connection, or if you are giving the device to someone else.

Key Takeaways

  • A power reset (unplugging for 30 seconds) solves most WiFi connection problems and is always the first step to try.
  • After a power reset, use the Google Home app to reconnect to your WiFi network by selecting the Chromecast and choosing your network.
  • A factory reset erases all settings and WiFi information, so only use it if a power reset fails or you are selling or giving away the device.
  • The factory reset button is a small hole on the back or bottom of the Chromecast; hold it for 10 to 15 seconds until the light flashes orange.

How to do a power reset

Unplug the Chromecast from the power outlet or remove the USB cable if it is powered through a TV USB port. Wait 30 seconds—this clears the device's memory and closes any stuck processes. Plug it back in and watch the light on the device. It will blink white or show other colors as it boots up.

Once the light stops blinking and settles into a steady state (usually white or off), open the Google Home app on your phone or tablet. Tap the Chromecast device in the app. If it does not appear, make sure your phone is on the same WiFi network you want the Chromecast to use. Tap the settings icon (gear) and select "Set up device" or "Forget device" and then set it up again. Follow the prompts to choose your WiFi network and enter your password.

How to do a factory reset

Locate the small reset button on the back or bottom of your Chromecast. On most models it is a recessed hole you cannot press with your finger—you will need a straightened paperclip, a ballpoint pen, or a similar thin object. Do not use anything sharp that could damage the device.

With the Chromecast plugged in, press and hold the reset button for 10 to 15 seconds. The light on the device will turn orange or flash rapidly, which signals that the factory reset is in progress. Release the button and wait for the light to return to its normal blinking pattern. This can take a minute or two. Once the light settles, the device has been reset to factory settings and all WiFi information has been erased.

After a factory reset, set up the Chromecast as if it were brand new. Open the Google Home app, tap the plus icon to add a device, select "Set up device," and choose "New device." Follow the on-screen steps to connect to your WiFi network. You will need to enter your WiFi password again.

When to use a power reset versus a factory reset

Use a power reset first. It takes 30 seconds and solves the majority of connection problems without erasing any settings. If your Chromecast reconnects and works normally after a power reset, you are done.

Use a factory reset only if a power reset does not restore the connection, or if you plan to sell, give away, or transfer the device to another person. A factory reset removes your WiFi password and any other stored information, so you will have to set everything up again. If you are troubleshooting a connection problem, try the power reset multiple times before moving to a factory reset.

What to check if WiFi still will not connect after a reset

Make sure your WiFi network is broadcasting its name (SSID). Some routers have a setting to hide the network name; if yours is hidden, you may need to enter the network name manually during setup instead of selecting it from a list. Check your router settings to confirm the network is visible.

Verify that your Chromecast is within range of the WiFi router. Chromecast devices work best within 30 feet of the router with a clear line of sight. If the device is in a far corner of your home or behind metal objects, move it closer to the router temporarily to test the connection.

Restart your WiFi router by unplugging it for 30 seconds and plugging it back in. Wait for all lights to stabilize before attempting to reconnect the Chromecast. Sometimes the router itself gets stuck and needs a reset.

If the Chromecast still will not connect after these steps, the device may have a hardware problem. Contact Google Support through the Google Home app or visit the Google Chromecast support page for further troubleshooting.

Frequently Asked Questions

Will a factory reset delete my Google account from the Chromecast?

Yes. A factory reset removes all account information, WiFi settings, and any paired devices. After the reset, you will set up the Chromecast as a new device and sign in with your Google account again during the setup process in the Google Home app.

Can I reset the Chromecast without the Google Home app?

A power reset requires only unplugging and plugging back in, so you do not need the app for that step. However, you will need the Google Home app to reconnect to WiFi after the reset. The app is the only way to configure the network connection on a Chromecast.

How long does a factory reset take?

The reset button press takes 10 to 15 seconds, and the device itself takes another minute or two to complete the reset process. Once the light stops flashing, the reset is done and you can begin setup. The entire process from button press to a working connection usually takes 5 to 10 minutes.

What if I forgot my WiFi password and cannot reconnect after a reset?

You will need to recover your WiFi password from your router or contact your internet provider. Check the back or bottom of your router for a sticker with the network name and password. If you changed the password and do not remember it, you can reset the router to factory settings, though this will erase any custom settings you made.

Does resetting the Chromecast affect other devices on my WiFi?

No. Resetting the Chromecast only affects that device. Your other phones, computers, and smart home devices will continue to work normally on your WiFi network.
