WLAN AutoConfig (Wlansvc) Service Defaults in Windows 7

The WLANSVC service provides the logic required to configure, discover, connect to, and disconnect from a wireless local area network (WLAN) as defined by IEEE 802.11 standards. It also contains the logic to turn your computer into a software access point so that other devices or computers can connect to your computer wirelessly using a WLAN adapter that can support this. Stopping or disabling the WLANSVC service will make all WLAN adapters on your computer inaccessible from the Windows networking UI. It is strongly recommended that you have the WLANSVC service running if your computer has a WLAN adapter.

Default Behavior

WLAN AutoConfig is a Win32 service. In Windows 7 it won't be started if the user doesn't start it. When the WLAN AutoConfig service is started, it is running as LocalSystem in a shared process of svchost.exe. Other system components, such as drivers and services, may run in the same process. If WLAN AutoConfig fails to start, Windows 7 attempts to write the failure details into Event Log. Then Windows 7 startup should proceed and the user should be notified that the Wlansvc service is not running because of the error.

Dependencies

WLAN AutoConfig is unable to start, if at least one of the following services is stopped or disabled:
