However, sometimes the Microsoft Virtual Wifi Miniport Adapter driver may cause problems, such as error messages, connection issues, or missing devices. In this article, we will explain what the Microsoft Virtual Wifi Miniport Adapter driver is, how it works, and how to fix common problems with it.


What is the Microsoft Virtual Wifi Miniport Adapter driver?




The Microsoft Virtual Wifi Miniport Adapter driver is a part of the Windows operating system that enables the creation of virtual wireless networks. It works by creating a virtual miniport adapter that acts as an intermediate driver between your physical wireless adapter and the Windows networking stack. The virtual miniport adapter can then create a separate wireless network with its own SSID and security settings, while still using the same physical wireless adapter.


The Microsoft Virtual Wifi Miniport Adapter driver is based on the Wireless Hosted Network feature that was introduced in Windows 7 and Windows Server 2008 R2. It uses a technology called Wireless LAN Device Driver Interface (WDI), which is the new Universal Windows driver model for Wi-Fi drivers. WDI enables device manufacturers to write a single driver that works with both Windows 10 for desktop editions and Windows 10 Mobile.


How does the Microsoft Virtual Wifi Miniport Adapter driver work?




The Microsoft Virtual Wifi Miniport Adapter driver works by using a feature called NDIS (Network Driver Interface Specification) Intermediate Driver. This is a type of driver that can intercept and modify network packets between an underlying miniport adapter and an upper-level protocol driver. The NDIS Intermediate Driver can then create one or more virtual miniports that can communicate with the upper-level protocol driver.


The Microsoft Virtual Wifi Miniport Adapter driver uses the NDIS Intermediate Driver to create a virtual miniport for each virtual wireless network that it creates. The virtual miniport has its own device name, which is obtained from the UpperBindings registry key. The virtual miniport also has its own initialization and configuration functions, which are called by NDIS when it receives an IRP_MN_START_DEVICE request from the Windows Plug and Play manager.


The Microsoft Virtual Wifi Miniport Adapter driver then uses the Wireless Hosted Network API to configure and manage the virtual wireless network. The Wireless Hosted Network API allows applications to set up parameters such as SSID, passphrase, channel number, and maximum number of clients for the virtual wireless network. The API also allows applications to start and stop the virtual wireless network, query its status and statistics, and receive notifications about events such as client connection and disconnection.


How to fix common problems with the Microsoft Virtual Wifi Miniport Adapter driver?




Some of the common problems that you may encounter with the Microsoft Virtual Wifi Miniport Adapter driver are:


  • The device is missing or disabled in the device manager.



  • The device shows an error code or a yellow exclamation mark in the device manager.



  • The device cannot create or connect to a virtual wireless network.



  • The device causes connection issues or conflicts with other wireless devices.



To fix these problems, you can try the following solutions:


  • Update the driver for your physical wireless adapter. You can use the Intel Driver Update Utility for wireless networking or download the latest driver from your wireless card manufacturer's website.



  • Uninstall and reinstall the Microsoft Virtual Wifi Miniport Adapter driver. You can do this by right-clicking on the device in the device manager and selecting Uninstall. Then restart your computer and the device will reinstall itself automatically.



  • Enable or disable the Wireless Hosted Network feature. You can do this by using the netsh wlan command in an elevated command prompt. For example, to enable the feature, type netsh wlan set hostednetwork mode=allow and press Enter. To disable the feature, type netsh wlan set hostednetwork mode=disallow and press Enter.



  • Adjust the power management settings for your wireless adapter. You can do this by right-clicking on your wireless adapter in the device manager and selecting Properties. Then go to the Power Management tab and uncheck the box that says Allow the computer to turn off this device to save power.



If none of these solutions work, you may need to contact your wireless card manufacturer or Microsoft support for further assistance.


How to use the Microsoft Virtual Wifi Miniport Adapter driver?




If you want to use the Microsoft Virtual Wifi Miniport Adapter driver to create a virtual wireless network, you need to have a compatible wireless card and a Windows operating system that supports the feature. You also need to have an application that can control the Wireless Hosted Network API, such as Connectify, Virtual Router, or Windows Command Prompt.


Here are the steps to create a virtual wireless network using the Microsoft Virtual Wifi Miniport Adapter driver:


  • Open the application that can control the Wireless Hosted Network API and enter the parameters for your virtual wireless network, such as SSID, passphrase, and maximum number of clients.



  • Start the virtual wireless network and wait for the application to confirm that it is running.



  • Connect your other devices to the virtual wireless network using the SSID and passphrase that you specified.



  • Enjoy your shared internet connection through the virtual wireless network.



To stop the virtual wireless network, you can use the same application that you used to start it and select the option to stop it. Alternatively, you can use the netsh wlan command in an elevated command prompt and type netsh wlan stop hostednetwork and press Enter.
