Fix: "Your device doesn't support Miracast" on Windows 11

You’re trying to cast your Windows 11 laptop to a big TV or wireless projector. You click the Cast button (or press Win + K). And then you see the dreaded message: Your Device Doesn't Support Miracast Windows 11: What

"Your device doesn't support Miracast, so you can't project to it wirelessly."

Before you panic or buy new hardware, know this: Your device likely does support it, but something is blocking it. Let’s break down what Miracast is, why this error appears, and how to fix it in minutes.

Fix 1: Update (or Roll Back) Your Wi-Fi Driver

Miracast relies heavily on your Wi-Fi adapter’s driver.

  • Right-click Start > Device Manager.
  • Expand Network adapters.
  • Find your Wi-Fi card (often has "Intel", "Realtek", "Qualcomm", "Broadcom").
  • Right-click > Update driver > Search automatically.
  • Still broken? Go to your PC manufacturer’s website, download the latest Windows 11 Wi-Fi driver, and install it manually.

Pro tip: Some Intel drivers break Miracast. If updating doesn’t help, try Roll back driver (if available) to an older version.

Reinstall the "Graphical" Wi-Fi Adapter

Miracast uses a hidden virtual adapter called "Microsoft Wi-Fi Direct Virtual Adapter".

  1. Device Manager > View > Show hidden devices.
  2. Look under Network adapters for any greyed-out item named "Microsoft Wi-Fi Direct Virtual Adapter".
  3. Right-click it > Uninstall device.
  4. Also uninstall your main physical Wi-Fi adapter (check "Delete driver").
  5. Restart. Windows will reinstall everything fresh.

In-Place Upgrade (Repair Install)

This keeps your files and apps but rewrites every system file.

  1. Download the Windows 11 Installation Assistant or Media Creation Tool from Microsoft.
  2. Run it and select "Upgrade this PC now".
  3. Choose "Keep personal files and apps".
  4. Let it run. After 45 minutes, Miracast will likely work again.

Fix 2: Enable "NDIS6.20" or "Wireless Display" in BIOS

Some laptops disable Miracast at the BIOS level.

  • Reboot your PC, press F2/F10/Del (varies by brand) to enter BIOS.
  • Look for Wireless Display, WIDI, or NDIS6.20 under Advanced/Config/Network.
  • Set to Enabled, save & exit.

Step 2: The Network Adapter Check

  1. Right-click the Start button and select Device Manager.
  2. Expand "Network adapters".
  3. Find your Wi-Fi card (look for words like Intel, Realtek, Qualcomm, or MediaTek).

Critical check: Right-click your Wi-Fi adapter > Properties > "Events" tab. Scroll through the information. If you see an error about "Device failed to start" or "Driver PnP", you've found the culprit. Troubleshooting Steps to Fix "Your Device Doesn't Support

Step 3: The Secret Reset (Network Reset)

Sometimes the "WiFi Radio" gets stuck. Windows 11 has a known bug where the network stack glitches.

  1. Go to Settings > Network & Internet.
  2. Scroll down to Network reset.
  3. Click Reset now.
  4. Let the computer restart. This often wakes up the Miracast capability.

Use a Third-Party Workaround (AirServer or Reflector)

If you absolutely cannot fix the driver issue (e.g., you have an ancient Wi-Fi card), buy a $20 Google Chromecast (uses different protocol) or software like AirServer ($20) which emulates a mirrored display via a different method.
