🛠️ Potential Fixes (If hardware supports it)

  1. Update Wi-Fi & graphics drivers (from manufacturer, not just Windows Update).
  2. Enable Wi-Fi adapter (even if not connected to internet).
  3. Restart the “WLAN AutoConfig” service.
  4. Uninstall virtual adapters (like from VMware, VirtualBox, or VPNs temporarily).
  5. Check Group Policy:
    Computer Config → Admin Templates → Windows Components → Miracast → Require Miracast support → Set to Not Configured.
  6. Use “Connect” app – press Win + K – Windows will recheck support.

Fix #6: The "Airplane Mode" Toggle Trick

This sounds absurd, but it works for many Realtek and MediaTek adapters.

  1. Turn ON Airplane Mode (via network icon in taskbar or Settings).
  2. Wait 10 seconds.
  3. Turn OFF Airplane Mode.
  4. Immediately press Windows + K.

This forces the Wi-Fi adapter to re-initialize its virtual "SoftAP" capability (which Miracast requires). If you see "Searching for devices" after this, the error is resolved.

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

Miracast relies heavily on your Wi-Fi adapter’s driver. Troubleshooting Steps to Fix "Your Device Doesn't Support

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

Fix 5: Use the "Graphics Settings" Workaround

Some Windows 11 builds have a bug where the "Cast" menu fails, but the underlying feature works.

  1. Press Win + I to open Settings.
  2. Go to System > Display > Graphics (scroll down).
  3. Under "Display connectivity," look for "Wireless display" or "Connect to a wireless display".
  4. If you see it, click it. If not, click Add an app > Browse and navigate to: C:\Windows\System32\Windows.applicationmodel.Store.testing.dll (don't worry, just browsing here sometimes triggers the system to recognize Miracast).
