How Do I Connect My Chromecast to My Wi-Fi?

When you set up your Chromecast for the first time, part of the setup process connects the Chromecast to your Wi-Fi. If you get a new router, move, or change your Wi-Fi settings, you’ll need to change the network on your Chromecast. There is no option to change the network directly, so this process requires you to have the Chromecast forget your network and then set it up again.

Here’s how to change the network on your Chromecast:

  1. Connect your phone or tablet to your Wi-Fi network, and install the Google Home app if you don’t already have it.

  2. Open Google Home on your phone or tablet.

  3. Tap your Chromecast.

  4. Tap Settings.

  5. Tap Wi-Fi.

Why Won’t My Chromecast Connect to My New Wi-Fi?

If you get a new Wi-Fi network for any reason, your Chromecast won’t automatically connect to it. The Chromecast will still have your old Wi-Fi information so that it won’t connect to the new network. To get the Chromecast connected to your new Wi-Fi, you’ll need to follow the steps in the previous section to have the Chromecast forget your old network and then set it up with your new network.

Having trouble connecting to your Chromecast in the Home app to change the network? If you factory reset your Chromecast, you will be able to set it up again and connect it to your Wi-Fi as if it were a new device.

Here are some other common Chromecast Wi-Fi problems and solutions:

  • Check the basics: Make sure the Chromecast is plugged into the wall and powered on. If the LED isn’t on, the Chromecast isn’t on, or the Chromecast is broken. The LED should be white. If the Chromecast is blinking white or another color, you will need to address the problem.
  • Ensure the device has adequate power: If you have intermittent connectivity issues, or the LED light doesn’t remain on and white all the time, you could have a power issue. The USB cable may be defective, or you might have a broken charger. Try switching the USB cable, power adapter, or both.
  • Update the Google Home app: Make sure the Google Home app is up to date on your phone or tablet. If you have an outdated Google Home app, it may fail to set your Chromecast’s Wi-Fi connection.
  • Fix signal strength problems: If there are any obstructions between your Chromecast and your wireless router, your Chromecast will have trouble connecting to the Wi-Fi network. If that's the case, try to improve your Wi-Fi signal. Use an HDMI extension cable to reposition your Chromecast, remove as many obstructions as you can, and consider repositioning the router.
  • Address network hardware problems: There may be an issue with your modem or wireless router. Even if other devices connect just fine, like your phone or laptop, an issue with your network hardware may be affecting your Chromecast. Reset your modem and router, and check to see if the Chromecast can connect.
  • Update or reset your Chromecast if necessary: If you’re unable to complete the setup process, or your Chromecast LED blinks red or orange, it may have an internal fault. Try to update your Chromecast or factory reset your Chromecast, and then see if you can set it up and connect it to Wi-Fi.
  • How do I reset a Chromecast?

    To reset your Chromecast, open the Google Home app and tap your Chromecast device > Settings (gear icon). On an iOS device, tap Remove Device; on an Android, tap More (three dots). Tap Factory Reset, and then tap Factory reset again to confirm.

  • How do I Chromecast from an iPhone?

    First, set up your Chromecast using the Google Home app for iOS. Then, on the Google Home app, tap the Media icon; under Manage Your System, choose whether you want to access music, video, radio, or podcast services. Select Link on your available streaming apps, such as Netflix and Hulu, then follow the prompts to link your account. Open the media you want to cast, click the Casting icon on your iPhone, and then choose your Chromecast device.
