Local Area Connection Rom, causing us no Internet access. Recently, the system user of Win7, the network connection has been normal when using the computer, but suddenly, the broadband connection is not connected, open the network branch sharing center, and found that "local connection" can not be found. How to do? Such a problem, we have to how to solve it good? Want to solve this problem is not difficult, it is a small series and we talk about solutions it!
The specific steps are as follows:
First, the taskbar does not have "local connection" and in the right-click "Network Neighborhood" & ldquo; attribute & rdquo; in the "local connection" .
This is the simplest loss of local connection. In fact, it is better to say that it is lost, or it is accidentally set to hide it, or the virus will modify its settings.
Solution: Right click on Network Neighborhood & mdash; Attribute & mdash; will open the network connection window, right click "local connection" & rdquo; & mdash; & ldquo; attribute & rdquo; & mdash; will see the following picture, the two hook Hook, click “OK” OK.
Second, nowhere can you see the "local connection" words.
This is a more complicated situation. We are divided into several steps to check, which may be caused by poor hardware contact, or driver error, or service is disabled, or system policy settings. Let's take a closer look at each of the solutions.
1. Plug and unplug the network card once.
If it is a separate network card, the loss of the local connection is mostly caused by poor contact of the network card. The reason is that the host is shaken or not cleaned for a long time. And caused poor hardware contact.
Solution: Shut down, unplug the power plug at the back of the main unit (very important), turn on the main unit, remove the fixed screws on the network card, and carefully remove the network card. Use tools to clean the motherboard dust (preferably with a hair dryer), especially to clean the slot of the network card, wipe the layout of the network card with a dry rag (must be dry), and then wipe the metal contact piece with rubber. Plug the network card into the original position, plug in the power, and start the test. If the local connection icon is found normally, the chassis is sealed.
If there is still no local connection, try again. If it doesn't work, it is probably a problem with the network card. Try to find one or buy a network card to test.
2, view the status of the locally connected device in the device manager
Right click "My computer" & mdash; & ldquo; attribute & rdquo; & mdash; & ldquo; hardware & rdquo; & mdash; & ldquo; Device Manager ”— See at least one of the "network adapter" items in the device list, as shown below (in order, down),
If it is empty, then The system does not detect the network card, right click on the icon of the top small computer “ scan detection hardware changes & rdquo;, check it.
If it is still not the hardware contact problem or the network card problem.
Right-click the corresponding network card in the network adapter to select "Attributes" and you can see the following figure. Here you can see the status of the network card, including status, drive, interrupt, power control, and so on.
If you find that the prompt is not working properly, you can try uninstalling the driver and restarting the computer. Or unmount the driver, unplug the network card, change a slot, and restart the computer. Since the system will re-detect the hardware, if it is not a hardware failure, the local connection here will generally be normal.
3, the local connection loss caused by the service process
Some friends accidentally disabled some services may also cause the local connection to be lost.
Solution: Right & ldquo; My Computer & rdquo; & mdash; & ldquo; management & rdquo; & mdash; & ldquo; Services and Applications & rdquo; & mdash; & ldquo; Services & rdquo ;, find & ldquo; Network Connections & rdquo; double-click, The following picture will appear:
Please note that the “Startup Type” and “Service Status” are not mandatory for the startup type. If you feel uncomfortable, you can change it to “ldquo”. "Automatic", it is important to "service status", it must be "started". If you can't set it here, please first change the "disable" in the “startup type" to “auto" or "manual", others will be modified.
We will see the "Dependency Relationship" button and will see "Remote Procedure Call (RPC)". So, look at the status of the “Remote Procedure Call (RPC)” service, making sure it also “automatic” and “already started”. Hint: There is also a “Remote Procedure Call (RPC) Locator” service that is not set.
We have already set up the service, so if we don't do it, we will set another important service as normal. Plug and Play This is the so-called "Plug and Play" detection service, of course, in accordance with the settings we mentioned above.
After the setting of the service process is completed, right click "My Network Neighborhood" & mdash; & ldquo; Properties & rdquo;, see the network connection window, refresh several times, see if there is any effect, it is not possible, restart once. If the local connection caused by the system service problem is lost, such a setting can be solved.
4, to check whether to delete the existing connection
& ldquo; start & rdquo; & mdash; & ldquo; run & rdquo; & mdash; enter gpedit.msc Click & ldquo; OK & rdquo ;, Expand & ldquo; User Configuration & rdquo;—“Windows Settings”—“Internet Explorer Maintenance"—“Connection"> In the sub-window to the right of the “Connection” folder, double-click “Connection Settings&rdquo ;Options. Look at the two figures below.
In the picture, delete the existing dial-up connection settings. Please do not check the box.
5, the laptop local connection is not much system configuration problem
As long as the system is connected, the local connection will be lost (the connection icon in the lower right corner is lost), and the network cable is no problem, after restarting You can go online.
In most cases, this is caused by the NIC being referenced in order to save power. Let's look at the solution.
Detailed step diagram: Right click "My Computer", select "Properties", click "Hardware", select "Device Manager" and find the "Network Adapter". Item, see the following picture:
Find the local connection driver project (wifi is wireless network in the above picture, 1394 is a high-speed transmission interface), Ethernet is the local meaning of the local connection, double-click it will appear the following figure;
Please confirm that the status of the device is "Use this device (enabled)", and then click "Power Management" to see the following picture:
Prompt "Allow the computer to turn off this device to save power", if you check this option, you will often be unable to access the Internet after standby. If you do not want to be less vulnerable to the Internet, remove the check.
Summary: In fact, this is also an option for many power-saving devices. If one of your devices cannot be used after standby, you must restart it. Try this method.
6, other. If the above steps are not possible, estimate the problem of the network card interface or the motherboard's network card chip. If you want to try again, the last hope is to redo the system, try it. I can only say so much.
Another: This article is a solution for a sudden loss of local connectivity for a normal computer. If you lost the local connection after reinstalling the operating system, please install the driver of the network card. In general, Winxp automatically adapts most of the network cards, but if it is a separate network card, try to install the driver of the network card once.
The above is just a small series of ways for Win7 to find out the local connection; is it very simple! Just follow the steps and you can solve this problem. Users who need it can try it!
