Setting up a Chromecast for a home office or on a home space needs certain requirements. You should note that preparation is needed to set up Chromecast quickly.

The process involves three essential things:

  • Fulfilling requirements

Once you have all of the above, you can proceed to the first step below.

Step 1: Ready the Requirements 

Before connecting your Chromecast to WiFi, there are a few things that you need to prepare. These include: 

  • Google Chromecast device (Third generation or older)
  • Updated Google and Google Home apps on your smartphone
  • A Google account you want to use for this process
  • Any display device with HDMI input (or socket), like a smart TV 
  • A smartphone or tablet that supports a 5 GHz connection so it can set up Chromecast on a 5 GHz network

Note: Chromecast doesn’t support a WPA2-Enterprise network.

  • Secure and compatible wireless network
    Here’s the WiFi networks compatibility: 
    • Chromecast Ultra: WiFi 802.11 b/g/n/ac 5 GHz network

Let’s say you followed the steps, and the Chromecast didn’t work. Find out more about this on the next one. 

In a nutshell: Chromecast setup follows a three-point step: 

  • First is readying requirements such as a Chromecast device, smartphone or mobile devices, a Google account, and a WiFi connection.
  • The second is attaching the Chromecast to a Smart TV while using Google Home.
  • The third part is connecting WiFi on a Chromecast through the Google Home app.

Troubleshooting Chromecast WiFi Connection Issues

You could encounter problems using Chromecast, which stops you from TV streaming. 

Here are some possible issues your Chromecast is having:

  • Weak WiFi signal that causes buffering or interruptions 
  • The Google Home app is not the latest version and needs an update
  • The device is out of the WiFi range
  • Wrong frequency of the wireless connection 
  • Not in the same WiFi network

As you read on, learn how to address these problems. 

Check for Blinking Lights on the WiFi Router

Assess the WiFi router to see if there are red or missing lights. You should restart and unplug the modem or router to reconnect to the internet until the red or missing lights return to normal. 

Verify the WiFi Connection 

See if the WiFi works for devices like your smartphone. If the WiFi connection works fine with other devices, it will probably work with the Chromecast. 

It will help if you ensure the Chromecast and smartphone have the same WiFi connection. To do this, here’s how: 

  1. Open Google Home on your smartphone. Tap the gear icon in the upper right corner to open the settings.
  2. Select Device Information. Scroll down and see what connection is under WiFi

Reboot Chromecast 

Your Chromecast might need a refresh. Restart the device with these steps:

  1. Open the Google Home and click the gear icon to open the settings. 
  2. Tap the three horizontal lines (hamburger or triple bar icon) in the upper right corner to open more settings. 
  3. Click Reboot

You can restart the newer version of Chromecast on the TV screen. Follow the steps below to do this: 

  1. Open your profile and click settings
  2. Tap the system and select restart. 

Use an HDMI Extender

Update Google Home App on Your Smartphone

For Android-powered devices, here’s how you update the Google Home application. 

  1. Open Google Play Store. Type in Google Home
  2. Tap on Google Home and click Update.

If you’re using an iOS-powered device, follow these steps to update Google Home: 

  1. Go to search and tap on your profile in the upper right corner. 
  2. Select purchased. Look for Google Home and tap on Update

Perform a Firmware Update 

If your Chromecast device still has trouble connecting, it might need a firmware update. 

In this example, we’re using a third-generation Chromecast. Here’s how: 

  1. Go to Google Support to see Chromecast’s firmware version on your desktop or smartphone. 
  2. Open Google Home on your smartphone and select your Chromecast device. 
  3. Go to settings and scroll down. At the bottom, it should show the Cast firmware version under Technical information
  4. If your Chromecast firmware needs an update, reboot it first (follow Reboot Chromecast in this section). 
  5. The firmware update will start when the Chromecast turns back on. On the TV, check the firmware version by going to settings.
  6. Tap about and system update and see the changes or updates. 

Check for Password or Router Changes 

Verify if there are any changes to the password router of the WiFi connection. If there are any changes to these, you need to update these on your Chromecast, too. 

To change the WiFi network, follow these steps: 

  1. Perform a factory reset following the Reboot Chromecast of this section. 
  2. When the Chromecast turns back on, open Google Home on your smartphone. 
  3. Open settings or the gear icon in the upper right corner.
  4. Scroll down and tap on forget next to WiFi. 
  5. A window prompt asks if you’ll forget the network. Tap on Forget network

After these steps, continue the setup process found in this article's Chromecast WiFi Setup section. 

Factory Reset Your Chromecast

Your last resort would be a factory reset of the Chromecast device. If you have tried everything and nothing works, you should reset and delete all data in your Chromecast. 

Factory reset is simple. To perform this, follow these steps: 

  1. Plug the Chromecast into the TV and the power outlet. 
  2. Press the Google Chromecast device's button for around 25 seconds.
  3. Release when it shows a white light. 
  4. To set up the Chromecast again, follow the setup guide earlier in this article.

When you tried all the steps and still nothing works, it's best to contact Google Support through [email protected]. You can also reach them on their Facebook, Made by Google

Wrap Up 

Connecting your Google Chromecast to WiFi requires some preparation to ensure a smooth process. These requirements include a Chromecast device and an internet connection. A Google Home application is also a must. 

You can troubleshoot the device if there are WiFi or Chromecast setup issues. You can check for the WiFi routers or perform a factory reset for Chromecast. If the problems persist, it’s best to consult Google Support.


Can Chromecast be used on different WiFi networks?

Yes, you can use another WiFi network. You must perform a factory reset to change the current WiFi network to another because Chromecast can remember one WiFi network at a time.

Are all Google Chromecast the same?

No, the versions of Google Chromecast offer similar and different features. Some of the things they differ with are the network frequencies, display resolutions, and pricing.

Can I cast to a TV using mobile data?

You can cast with mobile data if you’re in guest mode. Note that you cannot set up a Chromecast using mobile data. 

How to connect Chromecast to WiFi without a remote?

In connecting Chromecast to WiFi, you’ll need to reset the device. It will forget all set data before, including any virtual remote control. An alternative would be using a LAN wire to connect the TV and the WiFi modem.
