WLAN Extensibility Module Has Stopped Error

This post will tell you the causes of this error and how you can fix it. Stay on this page to learn more.

Why Does WLAN Extensibility Module Has Stopped Error Occurs?

The WLAN extensibility module has failed to start 10 error occurs due to several reasons, including a damaged wireless network adapter, problematic WLAN card and router drivers, and invalid entries. This WLAN extensibility module has failed to start. Error code 21 could also be a result of a virus.

– Damaged Wireless Network Adapter

A faulty wireless adapter means no communication between the internet and other computers. In short, your devices will not be able to communicate over a local area network.

Remember, this adapter requests an address from the server to reach the Network while using a wireless network. They take the PC’s signal and convert it into radio waves that transmit via an antenna. When this adapter is defective or malfunctioning, no connection is established.

– Outdated, Problematic, Corrupt WLAN Card and Router Drivers

Obsolete drivers negatively impact the performance of your system. An issue within the Wi-Fi card drivers will affect how the system connects to a wireless network. So, you may experience intermittent connection losses or complete loss of a connection.

So, when you start experiencing problems with wireless LAN issues, your Wi-Fi card drivers could be the cause. Check to see if they are dated or corrupt.

– Unacceptable Entries in the Windows Registry

When you tamper with the Windows registry, many systems within your PC may fail. This may occur due to incorrect or failed uninstallation or installation of a program, which might leave inappropriate entries in the Windows registry. This results in errors in Shared DLLs and Active X Controls.

Unacceptable Entries in the Windows Registry

Remember, the Windows registry acts as a database system for the OS and all other user software/application, installation, hardware, uninstallation, and updates. So, tampering with the registry can result in wireless LAN extensibility problems.

– Improper System Shutdown

An improper system shutdown can occur due to power outages, improper connection of power cables, using a non-original memory module, and malfunctioning power supplies. While the obvious consequence of improper shutdown is data loss, they can also cause network connection issues.

So, if your computer had an improper shutdown recently, its process might have tampered with the network module.

– Consequences of a Virus or Malware Attack

Viruses and malware are major causes of halting the wireless LAN modules. Typically, malware wreaks havoc on the entire computer and Network, halting your daily operation. So, when did you last run antivirus software? If you suspect an antivirus is causing the problem on your system, run an antimalware.

 

How to Fix The  WLAN Module Issues?

You can fix the WLAN autoconfig detected error by manually starting the WLAN autoconfig service. There are two methods to do this: the first is from the services page, and the other is from the command prompt. You can also restart the wireless network to get rid of this error.

– Manually Start WLAN AutoConfig Service

If you experience frequent issues with your PC detecting wireless connection, check the WLAN AutoConfig (WLANSVC) status. The WLAN Auto-Config helps Windows PCs discover a wireless network and connect to it. This service works the same way as the Wireless Zero Configuration(WZC) in Windows XP.

Manually Start WLAN AutoConfig Service

Sometimes the WLANSVC does not start automatically due to unknown reasons. This, in turn, leads to wireless connectivity issues because WLANSVC service manages wireless networks.

So, consider checking this setting if it is hard to connect to a wireless network. It is located in the services window under the display name WLAN Auto-config.

You can restart this service using two methods:

  • From the Services Page

Here is the procedure for restarting the WLANSVC from the Microsoft Services Window:

  1. Launch the run box – press the Win key + R button simultaneously
  2. Type services.msc and click OK.
  3. Search for WLAN Auto-Config from the list of services and right-click on it
  4. Select Properties from the drop-down menu and go to the General tab
  5. Under Startup type, ensure it reads Automatic
  6. Click Start

Once you start WLANSVC Service on your computer, you will be able to discover the available Wi-Fi networks.

  • From Command Prompt

Starting the WLANSVC service from the command prompt requires that you have Administrative rights. Here is how to use the DOS command to activate this service.

  1. Press the Win key and type CMD
  2. The Command Prompt app appears; click on Run as administrator
  3. When the Windows Command Processor appears, click Yes
  4. Type netsh and press Enter. Again, type WLAN and press the Enter button.
  5. Start the Wlansvc for a Wireless interface. Copy and paste, set auto-config enabled=yes interface=”Name of Wireless Network Connection.” This is the DOS command to start Wireless service on your Windows 10, 11, and Vista PCs. It is a must that you specify the wireless connection name as the interface. So, you will need to type the specific Wi-Fi network name.
  6. Press Enter to finish the process.

Now, access the internet to check the connection.

– Restart Wireless Network Connection

Here, you will need to disable the wireless network connection and enable it after a few seconds. This is an effective method for solving wireless connectivity issues.

Here is the procedure:

  1. Launch the Control Panel – type it in the search box and click on it when the app pops up.
  2. Select Network and Internet and go to Network and Sharing Center
  3. Click on the Wi-Fi connection you want to restart and select Disable
  4. Let it stay for a few seconds, and Enable the connection again.

Check whether you have a connection; try restarting your computer to see if it solves the issue.

Alternatively, turn on Wi-Fi on your device and ensure that the Airplane mode is off. Now, select the Manage Wi-Fi connections on the Wi-Fi quick setting, and see if your Wi-Fi Network appears in the list of networks.

If it does, select it, and try to connect to it. If it says Connected, select Disconnect, wait a moment, and then select Connect again.

Does it solve the issue? If it doesn’t, try running the Network troubleshooter. Click the start button, go to Settings, and select Network & Internet > Status. Select Network troubleshooter under Change your network settings and follow the steps in the troubleshooter to try to fix the problem.
