This error is often triggered for various reasons, including incorrect network configuration. Here we show you how to fix the “your PC or mobile device doesn’t support Miracast, so it can’t project wirelessly” error in Windows 11.

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

Miracast uses the Wi-Fi network to receive signals from your phone or tablet wirelessly. Most modern devices with Wi-Fi support Miracast and wireless display technology out of the box.

While the error indicates the device to be Miracast incompatible, the problem often is triggered due to external factors. It includes devices not connected to the same Wi-Fi network, display driver issues, incorrect Wi-Fi configuration, and third-party mirroring app conflict.

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

Miracast requires both devices to be connected to the same Wi-Fi network. Connect your Windows 11 computer to a Wi-Fi network if you are using an Ethernet connection. Also, connect your phone or tablet to the same Wi-Fi network.

To enable Wi-Fi on Windows 11:

Press Win + I to open Settings. Click on the Network & Internet tab in the left pane. Click on Wi-Fi and then toggle the switch for Wi-Fi to turn it On. Click on Show available networks and then click the Connect button to connect your PC to the Wi-Fi network. Connect the other device to the same Wi-Fi network. Launch the Connect app and check if the error is resolved.

If the wireless connectivity is not working, here’s how to troubleshoot Wi-Fi not working problem in Windows 11.

2. Check Your PC for Miracast Compatibility

Most modern Windows computers are Miracast compatible. However, if you have installed Windows 11 on an older system, check if it supports Miracast. This involves verifying the NDIS driver for the Wi-Fi card.

To check the NDIS driver version:

Press the Win + X to open the WinX menu. Click on Windows Terminal. In the Windows Terminal window, type the following command and press Enter: Get-netadapter|select Name, ndisversion Check the NdisVersion column for Wi-Fi. If it is 6. 30 and above, it means your system is Miracast compatible. If you have an older version driver installed, update it to the latest available version.

You can also view the Wireless Display support using PowerShell. Here is how to do it:

In the PowerShell window, type the following command and press Enter: netsh wlan show driver Look for the Wireless Display Supported section. Here both the Graphics Driver and Wi-Fi Driver should show Yes. If so, your system is compatible with Miracast.

3. Update Your Network Drivers

You can update your network drivers to get the latest version of the NdisVersion driver. Follow these steps to update your Wi-Fi adapter driver in Device Manager.

Press Win + R to open Run. Type devmgmt. msc and click OK to open Device Manager. In Device Manager, expand the Network adapters section. Right-click on your Wi-Fi adapter and select Update Driver. Select Search automatically for drivers. Windows will look for the available drivers and install them. Then, restart your PC to apply the changes and check for any improvements.

4. Reinstall the Wi-Fi Adapter

If no new drivers are available for the Wi-Fi adapter, you can reinstall the Wi-Fi device to fix common network problems. Here’s how to do it.

Press Win + X and click on Device Manager. In the Device Manager window, expand the Network adapters section. Right-click on your Wi-Fi device and select Uninstall device. Click Uninstall to confirm the action. Once uninstalled, click on Action in the Device Manager toolbar, and select Scan for hardware changes. Windows will look for connected but missing devices and reinstall the Wi-Fi adapter. Close the Device Manager. Open the Connect app and check if the device doesn’t support Miracast error is resolved.

5. Check and Configure Your Windows Firewall

Windows Firewall may prevent the adapter from connecting to the source device. You can temporarily disable the Windows Defender Firewall to determine if it is causing the issue. If so, you can allow the Wireless Display through the firewall to resolve the problem.

To disable Windows Defender Firewall:

Press Win + I to open Settings. Open the Privacy & Security tab in the left pane. Click on Windows Security. Click on Firewall & network protection under the Protection areas section. Click on your Public network (active) profile. Toggle the switch for Microsoft Defender Firewall to turn it Off.

Once the firewall is disabled, try connecting to a wireless display and check if the Miracast error is resolved. If yes, enable Windows Defender Firewall and then follow the steps below.

To allow Wireless Display through Windows Defender Firewall:

Press Win + R to open Run. Type control and click OK to open the Control Panel. Go to System and Security > Windows Defender Firewall in the Control Panel. Click on Allow an app or feature through Windows Defender Firewall in the left pane. Click the Change Settings button in the top-right corner. Scroll down and locate Wireless Display. Then, check the Private and Public column box. Next, locate the Connect app and make sure it is allowed in both Private and Public network. Click OK to save the changes.

6. Change the Wireless Mode Selection Value

Another workaround to fix this error is to set the Wireless Mode Selection value for the adapter to Auto in Device Manager. If the default value is set to 802.11 b\g, it may create issues with pairing.

To change the Wi-Fi adapter Wireless Mode Selection value:

Press the Win + R to open Run. Type devmgmt. msc and click OK to open Device Manager. Expand the Network adapters section. Right-click on your Wi-Fi adapter and select Properties. Open the Advanced tab. Under Property, select 802. 11 Wireless Mode. Then, click the drop-down for Value and set it to Auto/Dual Band. Click OK to save the changes. Close Device Manager and check if the error is resolved.
