What should I do if the "local connection" of the Win7 system computer is gone?

Recently, a Win7 system user encountered a problem in the process of using the computer, that is, the "local connection" of the network sharing center was gone, and the broadband could not be connected at this time. What is going on? ? After various attempts, I finally found an effective solution, which is now shared as follows.

First, the driver error:

1, right click on the desktop "computer" icon to select "properties", as shown.

2, the pop-up window found & ldquo; device manager & rdquo ;, as shown in FIG.

3, and now find the device manager & ldquo below; network adapter & rdquo ;, found in the following NIC driver has a yellow exclamation mark and yellow question mark.

4, there are question marks in the above procedure (exclamation mark) Right-click selection & ldquo; Driver Software Update & rdquo ;, as shown, a step reinstall the NIC driver, or a driver wizard The driver can also be installed automatically. Once installed, “Local Connection" will appear.

Second, the service program error:

1, if it is found in the Device Manager, no exclamation point and a question mark in front of the NIC driver, the driver as usual, this time it should consider the & ldquo ; network connection management service program & rdquo; error situation.

2, press and hold & ldquo; Win key + R & rdquo ;, keys appear & ldquo; run & rdquo; window, as shown in FIG.

3, sequentially & ldquo; run & rdquo; dialog input:

regsvr32 netshell.dll

regsvr32 netconfigx.dll

regsvr32 Netman.dll

and press Enter, the problem is solved.

The above is solved Win7 system & ldquo; Local Area Connection & rdquo; gone way, of course, sometimes it may be a computer Trojan horse virus, resulting in the local connection is hidden, then you can use anti-virus The software kills the virus.
