Win7 not wireless internet pc not running Windows wireless service

Click the wireless network shortcut key Fn+f5 (I am a notebook computer), suggesting that the computer does not have a wireless service, is the NIC bad, even if the network is broken, there are many other wireless network AH??

Open the Network connection Configuration interface, wired wireless network card is normal state, the lower left corner have fork.

Think of yesterday seems to shut down some of the services of the network Shield, is not conveniently shut down the other related services.

The service window opens to view a service that is not running.

Find a service WLAN AutoConfig for wireless networks

The WLANSVC service provides the logic needed to configure, Discover, connect, disconnect from the wireless local Area network (WLAN) defined by the IEEE 802.11 standard. It also includes the logic of turning a computer into a software access point so that other devices or computers can connect wirelessly to the computer using a WLAN adapter that supports it. Stopping or disabling the WLANSVC service will prevent all WLAN adapters on the computer from accessing the Windows network connection UI. Highly recommended: If your computer has a WLAN adapter, run the WLANSVC service.

This service is run automatically, but he is in a deactivated state, click Start, hint that the dependent service is not running, find his dependent service:

Extensible Authentication Protocol

Nativewifi Filter

NDIS Usermod I/O protocol

Remoteprocedure Call

Extensible Authentication protocol is not running, running him, or relying on services that are not running, this service relies on two services:

Cngkey Isolation

Remote Procedure Call

Find Cngkey Isolation

Sure enough, it was disabled.

Modify the properties, start the service, and then start the WLAN AutoConfig service.

Sure enough, the Internet connection was found immediately.

Cngkey Isolation

Yesterday closed the service too much, it seems to be a see his name contains "key", think it is the net Silver shield, directly off.

Edit PS:

Control Panel-Locate the Network Connections Properties menu, uninstall the Microsoft Network client, and then reinstall Microsoft Network Client to repair the Windows wireless service. After I tried a variety of methods, I found this available.
