Windows Vista WLAN Autoconfig
Unlike Windows XP, Windows Vista does not have the wireless zero configuration (WZC) service, instead the service used to detect available wireless network and manage wireless network profiles is called WLAN Autoconfig.
If you do not enable this feature, you need to use the other wireless utility which is provided by wireless adapter manufacturer in order to connect to wireless networks.
Graphical Interface Method
Here is how you can enable/disable this feature:
1. Go to Start and right click Computer. Select and click Manage.
2. Computer Management window will appear. Under Services and Applications, select Services.
(Another way to reach this is: Start -> Control Panel -> Administrative Tools -> Services
3. Scroll down and select WLAN AutoConfig.
4. Double-click the service and its properties window will appear. If the startup type is not set to automatic, click on the dropdown arrow and change it to Automatic. Click Start to start the service if it?¡é?€??s not started. Click OK at last.
