Fix Your Device Doesn’t Support Miracast
Fix 1: Make Sure Both Devices Use The Same Wi-Fi
Miracast works only when both devices are connected to the same wireless network. If your PC is using Ethernet and your phone is on Wi-Fi, the connection may fail. You can check it by:
1. Open Settings using Win + I.
2. Go to Network & Internet > Wi-Fi.
3. Turn On Wi-Fi.
4. Connect your PC to the same Wi-Fi network as your phone or tablet.
Now try again using the Connect app.
Fix 2: Check If Your PC Supports Miracast
Your old system might not be supporting wireless display features fully.
Verify Compatibility
1. Press Win + X and select Windows Terminal.
2. Type the command below and press Enter:
netsh wlan show driver
Look for Wireless Display Supported. If both the graphics and Wi-Fi driver say Yes, your PC supports Miracast.
Fix 3: Update Your Wi-Fi Driver
Outdated network drivers often cause Miracast errors. Here are the steps to update the driver:
1. Press Win + R and type devmgmt.msc.
2. Open Device Manager.
3. Expand Network adapters.
4. Right-click your Wi-Fi adapter.
5. Select Update driver.
6. Choose Search automatically for drivers.
Restart your PC after installation.
Fix 4: Reinstall The Wireless Adapter
If updating does not help. Reinstall the adapter completely. Below is the process to reinstall:
1. Right click on Start button and select Device Manager.
2. Expand Network adapters and Right-click the Wi-Fi adapter.
3. Select Uninstall device.
4. Restart your computer.
Windows will automatically reinstall the adapter.
Fix 5: Allow Wireless Display Through Firewall
Windows Firewall can sometimes block Miracast connections. So, let’s fix it with Firewall Blocking:
1. Open Control Panel.
2. Search for Windows Defender Firewall.
3. Click Allow an app through Firewall.
4. Enable Wireless Display and Connect for both Private and Public networks.
Fix 6: Change Wireless Mode Settings
Incorrect adapter settings can also trigger this error. You need to set up wireless mode to auto by:
1. Right click on Start button and select Device Manager.
2. Right-click your Wi-Fi adapter and open Properties.
3. Go to the Advanced tab, find Wireless Mode.
4. Set the value to Auto or Dual Band.
That’s it!
