If you are using the Microsoft Wireless Display Adapter, see the Microsoft Wireless Display Adapter troubleshooting guide.
  • Check the display Power saving mode. When a device is in power saving mode, most features do not work.
  • Windows update. Check for updates and install all available bits on your Windows 11/10 device and see if the current issue is resolved.

1]Run network troubleshooter

Since Miracast is running over the Wi-Fi network, you can run the network troubleshooter and see if the Miracast disconnects randomly issue on your Windows 11/10 device will be resolved. Otherwise, try the next solution.

2]Update driver

Update driver

Your Miracast not working problem is likely caused by driver issues – you may have incorrect, outdated, or corrupt device drivers on your PC. So you need to update your device drivers to see if that solves your problem. Below are your options for performing this task:

If updating the drivers didn’t help or if your drivers are already updated but the problem still persists, you can move on to the next solution.

3]Change network adapter power management

Change network adapter power management

To change the power management of the network adapter, simply disable the power saving mode of the network adapter. Here’s how:

  • Hurry Windows key + X to open the Power User menu.
  • Faucet M key on the keyboard to open Device Manager.
  • Once inside Device Managerscroll down the list of installed devices and expand the Network adapters section.
  • Next, double-click your network adapter to edit its properties.
  • In the property sheet, click Power Management tongue.
  • Now uncheck Allow computer to turn off this device to save power option.
  • Click on OKAY to save changes.
  • Exit Device Manager.
  • Restart the computer.

4]Configure unicast response

Configure unicast response

Unicast is one-to-one transmission from one point in the network to another point; that is, a sender and a receiver, each identified by a network address. The unicast reply option is useful if you need to control whether your PC receives unicast replies to its outgoing multicast or broadcast messages. The recommended state for this setting is: Nope.

If this setting is enabled and your PC sends multicast or broadcast messages to other computers, Windows Firewall with Advanced Security waits up to three seconds for unicast replies from other computers, then blocks all further replies. On the other hand, if the option is deactivated, and your the computer sends a multicast or broadcast message to other computers, Windows Firewall with Advanced Security will block unicast responses sent by these other computers

To configure unicast response, follow these steps:

  • Hurry Windows key + R to invoke the Run dialog box.
  • In the Run dialog box, type secpol.msc and press Enter to open Local Security Policy Editor.
  • In the snap-in console that opens, click the chevron (arrowhead) next to Windows Defender Firewall with Advanced Security to reduce the section.
  • Now right click Windows Defender Firewall with Advanced Security – Local Group Policy Object.
  • To select Properties from the context menu.
  • In the property sheet, click the Public profile tongue.
  • Click it Personalize button under Settings.
  • Click on the drop-down menu to Show notification option and select Yes.
  • Then click on the drop-down menu to Allow unicast response option and select Yes (default).
  • Click on OKAY all the way to save the changes.
  • Restart the computer.

If the problem persists, try the next solution.

5]Reset network adapter

Reset network adapter

Miracast uses WiFi Direct and Bluetooth technology. However, both are part of the protocol stack or network stack which is an implementation of a suite of protocols or a family of computer network protocols.

This solution requires you to reset the network adapter and see if that helps. If resetting the network adapter on your Windows 11/10 PC didn’t help fix the problem, you can try a wireless USB dongle. If this fixes the problem, you can ask a hardware technician to replace your built-in wireless adapter or just continue using the dongle.

6]Run the Hardware and Device Troubleshooter

Hardware and Peripheral Troubleshooter

To rule out the possibility of a faulty display, which may require replacement, you can run the Hardware and Peripherals Troubleshooter. You can also try connecting the display wirelessly to another PC and see if the problem persists.
