How to Fix Chromecast Not Connecting to WiFi on Windows 11: Step-by-Step Solutions

Chromecast is a popular device that lets you stream content from your computer or phone to your TV. However, sometimes it may have trouble connecting to WiFi, especially when using Windows 11. This can be frustrating when you just want to enjoy your favorite shows or movies.

There are several simple solutions you can try to fix the Chromecast WiFi connection issue on Windows 11. Most of these steps do not require technical knowledge and can be done quickly.

In this guide, we will walk you through easy-to-follow steps to help your Chromecast connect to WiFi smoothly again. Each solution is explained clearly, so you understand why it’s important.

Let’s get started and get your Chromecast back online.

Quick Note: Basic Checks Before You Begin

Ensure your Chromecast is plugged in and powered on. Without power, it won’t connect to WiFi.
Check your WiFi network is working properly. Try connecting another device to the same WiFi to confirm it’s active.
Make sure your Windows 11 PC is connected to the same WiFi network you want Chromecast to use. Chromecast and your PC must be on the same network to communicate.
Keep your Chromecast and Windows 11 PC close to the router. A weak WiFi signal can cause connection issues.

Step 1: Restart Your Devices

Restarting is the simplest and most effective way to fix many connectivity problems. It clears temporary glitches that may cause issues.

Unplug your Chromecast from the TV and power source.
Turn off your Windows 11 PC.
Wait for about 30 seconds to 1 minute.
Plug Chromecast back in and power it on.
Turn your PC back on and try connecting again.

This step refreshes network connections and often solves minor bugs.

Step 2: Check WiFi Network Settings on Windows 11

Your PC must be connected to the correct WiFi network. Follow these steps carefully:

Click on the WiFi icon on the taskbar (bottom right corner).
Look for your WiFi network name in the list.
If you are connected to a different network, click on the correct one and select Connect.
Enter the WiFi password if prompted.
Ensure your PC stays connected to this network while setting up Chromecast.

If your PC is connected to a guest or different WiFi network, Chromecast won’t be able to connect properly.

Step 3: Use the Google Home App to Set Up Chromecast

The Google Home app is the official way to manage Chromecast devices. It helps you configure WiFi and fix connection issues.

Download and install the Google Home app from the Microsoft Store if you don’t have it.
Open the app and sign in with your Google account.
Make sure your PC’s WiFi is on and connected to the desired network.
In the app, tap the + icon to add a new device.
Follow the on-screen instructions to detect your Chromecast.
Choose your WiFi network and enter the password when asked.

This process instructs Chromecast to join your WiFi, which is crucial for streaming.

Step 4: Verify WiFi Frequency Band Compatibility

Chromecast devices usually work best with the 2.4 GHz WiFi band. Some newer Chromecast models support 5 GHz, but compatibility depends on your router and device.

Check your router’s settings using its web interface or app.
Confirm that the 2.4 GHz band is enabled and broadcasting.
If your PC is connected to 5 GHz and Chromecast supports only 2.4 GHz, try switching your PC to 2.4 GHz.
Alternatively, connect both devices to the same band for better communication.

WiFi bands affect signal range and device compatibility, which is why this step matters.

Step 5: Disable VPN and Firewall Temporarily

VPNs and firewalls can block Chromecast from accessing the network properly.

If you use a VPN on your Windows 11 PC, try turning it off temporarily.
To disable the firewall:

Press Win + S and type Windows Security, then open it.
Click on Firewall & network protection.
Select your active network (usually “Private network”) and click Turn off firewall.

Try connecting your Chromecast again.

If disabling these helps, you may need to add exceptions for Chromecast in your firewall or VPN settings.

Step 6: Update Chromecast Firmware and Windows 11

Outdated software can cause connection problems. Keeping devices updated ensures they work smoothly.

Open the Google Home app and check if there is a firmware update available for Chromecast.
Follow prompts to update if needed.
On Windows 11, go to Settings > Windows Update and click Check for updates.
Install any available updates and restart your PC.

Updated devices have better security and connectivity fixes.

Alternative Method: Use Ethernet Adapter for Chromecast

If WiFi problems persist, you can try connecting Chromecast via Ethernet using a compatible adapter.

Purchase a Chromecast Ethernet adapter (official or third-party).
Connect the adapter to your Chromecast and plug an Ethernet cable from your router to the adapter.
This provides a stable wired internet connection, bypassing WiFi issues.

This method is useful in environments with poor WiFi signals or interference.
