Whether you are sharing ADSL dial-up Internet access or through a broadband router directly to the Internet, we are likely to encounter the network when the intermittent disconnection phenomenon. In the face of this type of network failure phenomenon, many friends often simply think that this is caused by poor signal contact, but when we carefully contact each of the joints, the network off line failure sometimes will occur repeatedly. In fact, there are many factors that cause the network to fall out of line frequently, to reject this phenomenon again, we should clear the way, layers of investigation, the various possible causes traced to the end, and timely adoption of targeted measures to deal with, I believe that this will be able to achieve the rejection of the network off the line of frequent purposes! Check physical equipment to ensure stable performance.
We know that if the physical devices that are connected to the network do not have a stable performance, they can easily cause the network connection to break down frequently if they continue to work for a long time. The "physical devices" mentioned here include network card devices, broadband router devices, ADSL dial-up devices, and even power supply devices that provide power to these devices.
Generally speaking, the physical equipment performance is good or bad, we simply use the substitution method can solve the problem. For example, when all workstations in a local area network do not have access to the Internet, that this fault should not belong to the individual behavior, but should belong to collective behavior, this kind of collective behavior only broadband router equipment or ADSL dial-up device performance can be affected, so we can basically eliminate this collective can not be online behavior must be independent of the network card device.
At this point, when the conditions permit, we can try to use the other normal broadband router devices, ADSL dial-up devices to replace the existing devices, in the case of the use of new devices, if all workstations in the LAN immediately to the Internet, it indicates that all the previous workstations have not been able to access the network failure, Must be by the broadband router devices, ADSL dial-up devices, such as the quality of their own, otherwise the network fault with the broadband router devices, ADSL dial-up device Independent.
If the local area network is only a very few workstations can not be normal access to the Internet or frequent drop-line failure, that this phenomenon is mostly the workstation's network card equipment itself caused by poor quality. At this point, we can also consider switching to other working normal network card devices to replace. Of course, for network card devices, in addition to their own poor quality, network card device driver installation operation is also very important, if the network card driver is not installed correctly, it may also cause the target workstation can not be online or network frequent failure of the line.
Under normal circumstances, we should try to choose the original network card driver, once there is no original driver, you may wish to download the corresponding model of the latest driver, and also to ensure that the network card driver applicable to the workstation system environment. If the local workstation system has installed the old version of the network card driver, we must use the System Device Manager in the device uninstall function, to the old network card driver completely removed from the system, before the installation of new network card drivers.
However, when we installed the latest version of the NIC driver, found that the network is still frequent drop, which means that the fault and network card driver-independent, at this time we should think of ways to restore the NIC driver to the previous working state, after all, the new version of the driver may be a bug, This poses a threat to the working stability of the NIC device. When the NIC driver is restored to its original state, we can use the driver Restore feature of the Windows XP system directly to achieve:
Right-click the My Computer icon in the System desktop first. From the shortcut menu that pops up, perform the Properties command, open the System Properties setting window for the local computer, click the Hardware tab in the window, and click the Device Manager button in the corresponding tab page. So we can see the system's Device List window.
Double-click the network adapter item in the Device List window, and then right-click the locally installed destination network card option under the pop-up branch, and open the Properties setting window for the target network card by executing the Properties command from the pop-up right-click menu.
Click the Driver tab in the window to open the label page as shown in the following illustration.
When you click the "Return Driver" button on the page, the system automatically restores the latest version of the network card driver to its previous drive state.
In addition, for broadband router devices, ADSL dial-up devices to provide power power supply, if the working state is not stable, it may also cause the network drop-line phenomenon occurs frequently. As you know, if the broadband router devices, ADSL dial-up device input voltage instability, may cause these devices continue to restart the phenomenon, resulting in frequent network drop-off phenomenon, this phenomenon is very easy to appear during peak consumption.
For example, the hot summer, I believe that many units are using air-conditioning, which may cause power tension, low voltage, resulting in the lack of input voltage, resulting in the network has been constantly off the line fault. In order to ensure that the network can stabilize the work, prevent the power instability leading to broadband router equipment, ADSL dial-up device hardware failure, I suggest that we should better for broadband router equipment or ADSL dial-up equipment with a voltage regulator.
