Event ID 10004 — Wireless Local Area Network (WLAN) Extensibility

Applies To: Windows Server 2008 R2

Windows can detect and report if the WLAN Extensibility module fails to start or stops unexpectedly.

The WLAN Extensibility module provides independent hardware vendors (IHVs) with more flexibility to support advanced features of IEEE 802.11 networks, and extend the built-in wireless client for additional wireless services and custom capabilities. For example, IHVs and independent software vendors (ISVs) can use WLAN Extensibility to provide customized configuration dialog boxes and wizards to display custom ISV or IHV wireless features and capabilities that are not provided by default in Windows.

Event Details

Resolve

WLAN Extensibility Module time out

There are three actions that you can take to resolve this error:

1. Disable the Wireless Network Connection, and then enable the Wireless Network Connection.
2. Restart the WLAN AutoConfig service (Wlansvc).
3. Contact the independent hardware vendor (IHV) provider for your hardware.

To perform these procedures, you must be logged on by using a local computer Administrator account, or you must have been delegated the appropriate authority. If you are not logged on by using an account that belongs to the Administrators group, you must be able to supply administrator credentials, in order to run the command prompt as administrator.

Disable the Wireless Network Connection, and then enable the Wireless Network Connection

To disable the Wireless Network Connection, and then enable the Wireless Network Connection:

1. Click Start, click Control Panel, click Network and Internet, click Network and Sharing Center, and in Tasks, click Manage network connections.
2. Right-click the Wireless Network Connection that you want to manage, and in the drop-down menu, click Disable.
3. After the Wireless Network Connection is disabled, right-click the connection, and then click Enable.

If the error persists, follow the steps in the next procedure to restart the WLAN AutoConfig service.

Restart the WLAN AutoConfig service (Wlansvc)

To restart the WLAN AutoConfig service (Wlansvc):

1. Click Start, right-click Computer, and then click Manage.
2. In Computer Management (Local), click Services and Applications, and then click Services.
3. In the details pane, under Name, navigate to WLAN AutoConfig.
4. Right-click WLAN AutoConfig, click Properties, and on the General tab, in Startup type, select Automatic, and then click Start.
5. Click OK.

Contact the IHV provider for your hardware

• Contact your computer manufacturer, or the manufacturer of your wireless network adapter for the most recent adapter drivers.

Verify

There are two methods to verify wireless extensibility settings are applied:

• Verify wireless independent hardware vendor (IHV) extensibility settings are applied by using the netsh wlan command
• Verify wireless IHV extensibility settings by using the profile properties

Verify wireless IHV extensibility settings are applied by using the netsh wlan command:

1. Click Start, and in Start Search, type cmd, and then press ENTER.
2. At the command prompt, type netsh wlan show interfaceInterfaceName (where InterfaceName is the name of the wireless connection listed in Network Connections), and then press ENTER.
3. If IHV extensibility settings are applied, then the command will render a message indicating IHV extensibility settings applied on the connection.

Verify wireless IHV extensibility settings by using the profile properties

1. Click Start, click Control Panel, and then click Network and Sharing Center.
2. In Tasks, click Manage wireless networks.
3. Double-click the wireless profile, to open the wireless connection profile properties dialog box.
4. If IHV service is installed, an IHV check box is displayed on the Connection tab.
