How to Fix the Device Does not Support Miracast Error in Windows 11

There is nothing that can dampen one’s spirits quite like an error message, and this typical Miracast one is no exception. Thankfully, all that is required is a few simple actions to rectify the situation.

You may mirror the screen of your Android or iOS smartphone, tablet, or even another Windows computer to your own computer by using the Connect software that comes with Windows 11. On the other hand, when you try to run the application, you can get an error message stating that “this device does not support Miracast, thus you can’t project to it wirelessly.”

This error may be brought about by a variety of factors, the most common of which is an improperly configured network. In this article, we will teach you how to solve the issue that occurs in Windows 11 and states that “your PC or mobile device doesn’t support Miracast, thus it can’t project wirelessly.”

What Causes the “Device Doesn’t Support Miracast” Error on Windows?

Miracast is able to wirelessly receive signals from your mobile device, such as a phone or tablet, by using the Wi-Fi network. Miracast and other forms of wireless display technologies are supported out of the box on the vast majority of current devices that have Wi-Fi.

Although the error message suggests that the device in question does not support Miracast, the issue is most often brought on by variables that are not internal. This includes devices that are not connected to the same Wi-Fi network, problems with the display driver, improper setting of the Wi-Fi network, and conflicts between mirroring apps from third-party developers.

1. Connect Both Devices to the Same Wi-Fi Network

Both of the devices need to be linked to the same Wi-Fi network in order for Miracast to operate. If you are connected to the internet through Ethernet, you should link your Windows 11 machine to a wireless network instead. Additionally, link your mobile device, whether it a phone or a tablet, to the same Wi-Fi network.

To activate Wi-Fi on Windows 11, do the following:

Both of the devices need to be linked to the same Wi-Fi network in order for Miracast to operate. If you are connected to the internet through Ethernet, you should link your Windows 11 machine to a wireless network instead. Additionally, link your mobile device, whether it a phone or a tablet, to the same Wi-Fi network.

To activate Wi-Fi on Windows 11, do the following:

• To launch the Settings menu, press Win and I together.
• To access the Network and Internet tab, choose it from the menu on the left.
• To activate Wi-Fi, first choose it from the menu by clicking on the icon, then flip the switch to the “On” position.
• To connect your personal computer (PC) to the Wi-Fi network, first choose the option to Show available networks, and then select the Connect button.
• Establish a connection between the second device and the same Wi-Fi network.
• Start the Connect app and check to see whether the problem still exists after you’ve fixed it.

2. Check Your PC for Miracast Compatibility

The majority of current machines running Windows are compatible with Miracast. Whether you have Windows 11 installed on an older computer, you should check to see if it supports the Miracast streaming protocol. This requires making sure that the NDIS driver for the Wi-Fi device is up to date.

To determine the current version of the NDIS driver:

• To access the WinX menu, press the Win key and the X key simultaneously.
• Simply choose the Windows Terminal option.
• In the window labelled “Windows Terminal,” enter the following command and then hit the Enter key

Get-netadapter|select Name, ndisversion

• Check the Wi-Fi availability in the NdisVersion column. If it is 6.30 or above, it indicates that your system is compliant with the Miracast standard. If you are using an older driver version than what is currently available, you should upgrade to the most recent one.

Utilizing PowerShell is another option for evaluating the support for Wireless Display. This is the procedure to follow:

• In the PowerShell window, type the following command and press Enter:

netsh wlan show driver

• Locate the section labelled “Wireless Display Supported” in the manual. In this section, the answer “Yes” should appear next to both the Graphics Driver and the Wi-Fi Driver. If this is the case, then your machine is Miracast compliant.

3. Update Your Network Drivers

You may acquire the most recent version of the NdisVersion driver by updating the network drivers on your computer. In order to get your Wi-Fi adapter driver in Device Manager up to current, follow these instructions.

• To launch Run, press the Win key and the R key simultaneously.
• To access the Device Manager, just type devmgmt.msc followed by the OK button.
• Within Device Manager, expand the area labelled “Network adapters.”
• Select “Update Driver” from the context menu that appears when you right-click on your Wi-Fi device.
• Select the option to automatically search for driver updates. Windows will search for available drivers and install them automatically once it finds them. After that, you will need to restart your computer in order to make the changes and check for any upgrades.

4. Reinstall the Wi-Fi Adapter

In the event that no updated drivers are available for the Wi-Fi adapter, you may attempt to repair typical network issues by reinstalling the Wi-Fi device. The procedure is as follows.

• Windows key plus X, then click the Device Manager icon.
• In the window for the Device Manager, expand the area labelled “Network adapters.”
• Select “Uninstall device” from the context menu that appears when you right-click on your Wi-Fi device. To confirm the operation, click the Uninstall button.
• After the application has been removed, return to the Device Manager’s toolbar, click on Action, and then pick Scan for hardware changes. Windows will search for connected devices that are missing, and it will reinstall the Wi-Fi adaptor if it finds any.
• Put an end to the Device Manager session. Launch the Connect app and verify whether or not the issue with the device not supporting Miracast has been fixed.

5. Check and Configure Your Windows Firewall

It’s possible that the adapter won’t be able to connect to the source device because of Windows Firewall. It is possible to temporarily deactivate the Windows Defender Firewall in order to establish whether or not it is the source of the problem. If this is the case, the issue may be remedied by allowing the Wireless Display to pass past the firewall.

To deactivate Windows Defender Firewall:

• To launch the Settings menu, press Win and I together.
• Launch the Privacy & Security tab located in the left pane of the settings menu.
• Simply choose the Windows Security option.

• Under the heading Protection regions, choose the option labelled “Firewall & network protection.”

• To access your active profile on the Public network, click on that profile.

• To deactivate Microsoft Defender Firewall, you need to slide the switch to the Off position.

After you have removed the firewall, you should next attempt to connect to a wireless display and check to see whether the Miracast problem has been fixed. If this is the case, then make sure Windows Defender Firewall is turned on, and then continue with the procedures below.

To enable Wireless Display while maintaining protection from Windows Defender Firewall:

• To launch Run, press the Win key and the R key simultaneously.
• To access the Control Panel, type control followed by the OK button.
• Within the Control Panel, go to the System and Security > Windows Defender Firewall section.

• In the left pane of Windows Defender Firewall, choose Allow an app or feature via Windows Defender Firewall.
• Simply go to the top-right corner of the screen and choose the option labelled “Change Settings.”

• Keep scrolling down until you find the Wireless Display option. After that, make sure the Private and Public column boxes are checked.
• Locate the Connect app and check to see that it has permission to access both the private and public networks.
• To save the changes, click the OK button.
