How to Fix Roku Screen Mirroring not Working on Windows?

These would include symptoms generally shared with Windows: a progress bar that stops and an error message. Generally, in these cases, there is some sort of problem in compatibility with Miracast. The most common cause is interference between devices on different WiFi bands, although technically they should all be on the same frequency, such as 5 GHz. 

Potential causes could be drivers for Windows, which are quite outdated, or the settings within your firewall, or perhaps new Windows updates.

Now that the causes are out of the way, it is time to discuss how to actually fix it.

1. Install the Latest Windows Build

This could be an issue if your operating system of windows is not updated to a version which contains all the essential updates required for screen mirroring. There are a number of compatibility issues and flaws present in the earlier versions of the windows device-to-Roku streaming software known as Miracast. If you experience problems while connecting, an upgrade to the latest versions of Windows should fix those issues. This also upgrades the drivers and enhances their compatibility with both the networks and the devices.

Open the tab in the Settings program with hotkey Win + R and then paste the following string ms-settings:windowsupdate and press Enter.

Check for updates-perform a click on the Check for updates button and let the system take some time to finish checking for updates. Tap the onscreen prompts to install found updates.

If it had asked you to restart your device while updating, after the restart, log in again to this page to make sure all is updated.

Once all updates are loaded, reboot your computer. Afterwards, check to see if the problem of Roku Screen Mirroring has been fixed.

2. Unplug Roku from All Devices

The process can also halt when your Roku driver gets stuck, and thereby your system thinks it's still trying to connect. By removing and re-adding the device, Windows will recognize the Roku device as new and clear all the previous data. This will resolve any issues that are preventing screen mirroring.

You can also open the Connected Devices section in the Settings app using the Run dialog box: press Windows key + R, enter ms-settings:connecteddevices in it, and press Enter.

Once you see your Roku device in the Bluetooth & other devices area, select it then select Remove device.

Select the "Add Bluetooth or other device" option that appears at the top of your screen.

From the Add a device window, select Wireless display or dock. When you see your Roku device select it then follow any on-screen instructions to complete setting up the device.

Once you are done following these steps, restart your computer to see whether screen sharing with Roku is working.

3. Make Sure Your Network Is Set To Private

Once your network has been set to private, your PC and Roku will be connected to perform a screen mirroring by allowing the necessary features.

Using Windows + I, open the Settings application.

Proceed and enter the Network & Internet section.

Go to Network Status, click on your network adapter and go to Properties.

Under Network Profile, set it as Private instead of Public.

To reconnect with your RokuTV, restart your computer.

4. Update to Latest Wireless Network Driver

In any case, updating the wireless network driver would better improve connectivity with other devices. Using an outdated driver might set you behind in terms of performance because it does not support the latest available wireless updates. The upgrade would carry better standards of maintaining a good connection with bug fixes that would see it easier to maintain constant connectivity useful for screen mirroring.

Hit the Windows key + R, then type in devmgmt.msc and hit Enter. If prompted by UAC, click Yes.

Then click on Network Adapters, find your wireless adapter, right-click it, and select Properties.

Click the Driver tab, where you can find Update drivers.

Once you have made that selection, follow on-screen instructions to install driver updates.

Try restarting your computer to see if it resolves the issue with Roku screen mirroring.
