Common troubleshooting examples for network cards

Network card as a connection between the computer and the bridge and the link, its performance and computer performance is closely related to the Internet! network card in the long time for US "service" process, often will inevitably appear some "strike" phenomenon, this kind of strike phenomenon is due to the quality of the network card is not perfect, Some of our network card improper operation caused, there are some of us in other aspects of computer operations inadvertently affect the performance of the network card, which led to a strike phenomenon. Generally this kind of strike phenomenon, is not out of the network card voluntarily, so in the elimination of such a network card strike failure, we must investigate its root cause, find out the ultimate sin huai culprit, but also an innocent body card! This is not, the article below for everyone to contribute a few of this aspect of the network card strike failure, and for these failures to put forward the appropriate response coup, Hope to be able to help you to use their own network card equipment effectively.

1, copy files cause network card installation failed

In a computer with a Windows 98 operating system, when we first install a driver for a network card device, when we specify a specific driver file for it, we suddenly encounter a computer crash or blackout in the process of copying the system source files, or we are prompted to insert Windows 98 System CD and we did not insert the installation disc as required to copy system files, then the network card device will be prone to installation failure failure. Later, even if we enter the System Device Manager window, the already installed network card device directly removed, and then ready to restart the computer system to install the network card driver, the system will still prompt some or all of the network function has been invalidated, so that the NIC device can not be properly installed into the computer system.

When confronted with this symptom, we should first install the Windows 98 system installation CD-ROM and the network card driver installation disk in hand, and then restart the computer system, in the process of booting in time to press the F8 function key, in order to successfully enter the system Safe mode of operation; then in safe working mode, Click "Start" with the mouse, "Control Panel, System, Device Manager, open the system's Device Manager window, locate and expand other devices in the window, and then select the network card device with the yellow question mark, and right-click the device, From the pop-up right-click menu, perform the delete command so that the previously installed NIC device can be deleted directly from the computer system.

Then click the "Start", "Run" item in the system desktop, open the system's Run dialog box, enter the string command "regedit", and click OK to open the system's registry editing interface; position mouse to Hkey_local_machine\ System\currentcontrolset\services\vxd the registry subkey, and then selects and deletes the DFS entry and the Vnetsup item under the corresponding VXD registry subkey.

Next click the "Start" in the system desktop, "Control Panel command, in the Control panel window that pops up, double-click the Network icon to open the Network Properties Settings window, select and delete the Dial-Up Networking adapter item in the window, and then click the OK button. Finally restart the computer system, this time we will find that the network will not be prompted at this time some or all of the functions have been invalidated, and the system will automatically search the corresponding slot into the computer network card devices, then we follow the prompts to specify the location of the network adapter driver installation and Windows 98 the specific path of the system installation disc, then click the "Next" button, the system can begin to correctly copy the relevant driver files and system files, wait until the NIC device driver installed after the installation, restart the computer system again, so that we can see the system on the desktop of the Network Neighborhood icon. Then we go to the system through the Network Neighborhood icon to set up the window, and in the window correctly configure the parameters of the network card to ensure that the network card can provide services to us correctly.

2, the clone system causes the double network card fault

The performance configuration of each workstation in the local area network is almost identical, and after one workstation has installed the operating system and set up the network card parameters, the local area network administrators will often use the system cloning method to quickly install the system and configure the network card parameters for other workstations. However, the installation of other workstation systems with network cards after the system cloning operation, often appear double network card failure, specifically that a workstation was only installed a network card, but the system after the cloning of the system in the Network Property Settings window, unexpectedly found two network card devices, The reason for this failure is that the slot where the network card is located may be different. In the face of this failure, although we can be true, fake two network cards are all removed, and then reinstall the NIC device driver to eliminate the dual network card failure, you can also give the real, fake two network card devices set exactly the same Internet parameters, to eliminate the dual network card to bring us trouble; But these methods not only operate trouble, And it's time-consuming. Then we have no way to two of the network card in the fake network card device to find out, and then remove it from the system and only keep the true network card? The author after careful pondering found that the true, false network card devices appear in the settings of the Web properties of the location of the window is generally fixed. Into the Network Properties Settings window, we can see the Configuration tab page appears in two network card devices, under normal circumstances a network card device is a virtual network card, and the bottom of that a network card device is the real network card, at this time we only in the Configuration tab page in the top of the network card and the corresponding agreement with the network card deleted, This will be able to keep the real network card equipment alone.
