TLDR

If you’re wondering how to change the WiFi network on a Chromecast, this guide walks you through the entire process step-by-step—whether you’re using Chromecast with Google TV or an older model. From switching networks in the Google Home app to resetting your device when the old Wi-Fi is unavailable, this tutorial covers everything you need to stay connected and stream seamlessly. Ideal for beginners, it also includes troubleshooting tips and expert advice to ensure a smooth transition to your new Wi-Fi network.

Introduction

Need to connect your Google Chromecast to a new Wi-Fi network? Whether you’ve moved house, upgraded your router, or switched internet providers, updating your Chromecast Wi-Fi connections is easier than you think. As a WordPress expert who often helps clients troubleshoot home tech and professional settings, I’ve broken this down into simple steps anyone can follow for uninterrupted streaming experiences and a seamless streaming setup.

What to Know Before You Start

Your Chromecast can only connect to one Wi-Fi network at a time. So when your home network changes, you’ll need to reconnect it manually to enjoy consistent streaming experiences and access for streaming content.

Common Reasons You Might Need to Change WiFi:

  • You’ve moved to a new place
  • You got a new modem or wireless router (like a Linksys router or office router)
  • You changed your internet provider
  • You upgraded to mesh Wi-Fi or Tata Play Fiber’s high-speed internet

What You’ll Need:

  • Your Google Chromecast and a TV with an HDMI port
  • A smartphone or Android device with the Google Home app
  • The new Wi-Fi network name and Wi-Fi password
  • (Optional) A paperclip if you need to reset your Chromecast

Step-by-Step: Change WiFi on Chromecast

If You Have a Chromecast with Google TV:

  1. Turn on your TV and Chromecast.
  2. Go to the Settings menu (top-right corner of your screen).
  3. Tap Network & Internet > Wi-Fi.
  4. Choose your current network and tap Forget network.
  5. Now, pick your new Wi-Fi network from the list of Wi-Fi networks and enter the password.

If You Have a Chromecast (3rd Gen or Older), Chromecast Ultra, or Chromecast Audio:

  1. Make sure your mobile phone is connected to the same Google account as your Chromecast.
  2. Open the Google Home app.
  3. Tap and hold your Chromecast device from the Devices tab.
  4. Go to Settings > Device Info > Wi-Fi > Forget this network.
  5. Back on the app home screen, tap the + icon.
  6. Choose Set up device and follow the screen instructions to reconnect. This is the core of the Chromecast Wi-Fi setup process.

Can’t Connect to Old WiFi? Try a Factory Reset

If you no longer have access to your old Wi-Fi network, you’ll need to reset your Chromecast to factory settings:

How to Reset:

  1. Find the reset button on your Chromecast.
  2. Hold it down until the light flashes white.
  3. Unplug the USB or micro-USB power cable, then plug it back in.
  4. Open the Google Home app and set it up again on your new network.

This returns your device to factory conditions and is often necessary when dealing with router configuration issues, outdated firmware, or poor Wi-Fi signal strength.
