How to make the NIC work stably

In the broadband Internet everywhere today, ordinary netizens and network card contact opportunities are increasing; but because the network card is naturally inconspicuous, and always hiding in the chassis inside, so people's attention to the network card is not very high. In fact, the advent of broadband Internet access in the process of slow open pages, on the Internet when the fault continues, most of the time is due to the instability of the NIC, but people usually ignore the existence of network cards, so in the face of the Internet failure they always blindly complain that the number of Internet or network bandwidth is not large enough, It is not thought that such a failure is due to their usual poor to the network card caused. In order to improve the speed of surfing the Internet, to ensure the stability of the network transmission, this article deliberately from five places, to fully protect the network card can work stably!

From the Plug and pull to ensure stable contact

As you know, when the NIC is in normal working state, the signal on the network card should be in a long light, and in the process of transmitting the signal, the network card signal lamp will keep flashing. If we're on a network connection, found that the network sometimes do not pass the phenomenon, we should look at this time the network card signal is in what state, once found that the network card signal is also flickering, the phenomenon of transmission instability is mostly due to the NIC and computer motherboard in the PCI slot contact caused by bad. Similar to other common PCI devices, frequently plug in the network card device, it is easy to cause the network card and PCI slot contact with the phenomenon of unreliable, so the stability of the network card work will be difficult to be guaranteed. In order to improve the working stability of the network card effectively, we try not to plug the network card frequently, because it is easy to support the interface of a large PCI slot, resulting in the network card can not close contact with the PCI slot, and when installing the network card, it is necessary to forcibly plug the network card into the bottom of the PCI slot, if the network card insertion depth is not The phenomenon of bad contact is very easy to appear. In addition, if the NIC is inserted into the PCI slot, found that the card's gold finger surface covered with thick oxide layer, we must first use the rubber to clean the surface of the gold finger, and then to plug the network card into the PCI slot, otherwise the thick oxide layer will hinder the network card and PCI slots close contact.

From the driver to ensure good compatibility

Network card to be stable and efficient to play a role, must be inseparable from the network card driver "effective" support. However, the NIC is not the same as other devices, its driver is often not very compatible with the motherboard driver or Windows operating system, or its driver has a number of bugs, often lead to a variety of baffling network card problems, such as the use of Realtek The 8469-series Chip's network card works in the Windows 2000 operating system environment, and is particularly vulnerable to failure prompts such as NetBIOS TCP/IP errors. To this end, we choose and install the network card, as far as possible to choose a better brand, higher quality network card, while trying to use the network card randomly equipped with the driver, after all, the brand is the network card to provide the driver performance is more reliable, and the compatibility is relatively good. When we found that some of the network card inexplicable failure, you may want to search the Internet network card should be the latest driver of the chip, of course, the search card driver has been the best of Microsoft's WHQL certification, after all, certified network card driver and the compatibility of Windows system is to do reliable; After you find the latest NIC driver, uninstall all the previously installed NIC drivers, and then use the manual positioning method to update the driver for the installation of the network adapter. Under normal circumstances, when we will the network card hardware quality and wiring connections, and other factors, still found that the NIC can not stabilize the work, then we may wish to update the network card driver or reinstall network card-driven methods to try to eliminate the network card can not stabilize the failure of the work, may receive miraculous. If we find that the network card device is not stable after updating the driver, it means that the new network card driver instability factors, at this time we can consider the use of System recovery function to restore the network card driver to the previous state, if the system does not restore the function, We can use the network card randomly equipped with the driver to restore the NIC driver to the normal state.
From the magnetic field, make sure to stay away from interference

In strict sense, the network card should belong to a relatively "fragile" electronic equipment, the equipment in the process of work is very susceptible to nearby electric or magnetic field interference, resulting in its inability to stabilize the work. Therefore, when installing a network adapter or laying out a cable try to choose a good shielding performance card or network cable, while installing the network card, as far as possible to keep the NIC away from other PCI card, or the condition allows the computer system to temporarily use the card removed to prevent these cards too close to the network card, The network card can cause magnetic interference or electric field interference. One more thing to remind you is that do not let the network card equipment for a long time near the television, refrigerators, microwave ovens and other high-power, strong magnetic field equipment, so as to indirectly improve the stability of the network card work; In addition, the network connection cable in the line, as far as possible not with High-voltage cable or other communication cable 绞缠 together, Otherwise, the network connection is also prone to unstable phenomena.

From interruptions, make sure to stay away from conflict

Although the NIC device can support Plug and Play, the system generally can automatically allocate the appropriate interrupt request resources when installing the NIC driver, but once the network card default interrupt request resource is manually assigned to a video card, modem or sound card, And the computer system can not timely to the network card driver redistribution of other appropriate interrupt request resources, the network card is easy to conflict with other devices, which affect the performance of the network card normal play. For example, the Realtek series card is particularly easy to "scramble" IRQ10 resources with the display card device. When there is a resource conflict between the NIC and other devices, we may want to look at the computer board instructions to see which of the PCI slots in the motherboard has the highest priority, and then try to insert the device that is prone to conflict of resources into the highest priority PCI slot to see if the device conflict can be eliminated. If not, then swap the conflicting device into another slot to try it until the device conflicts are removed. In addition, if we are familiar with the operation of the computer, you can also enter the properties of the Network Card window, using manual method for the network card to reassign the appropriate interrupt request resource number; When you manually assign an interrupt request resource number to a network card, follow these steps:

Click Start/Settings/Control Panel commands, and in the System Control Panel window that opens, double-click the System icon, and then in the pop-up System Properties setting interface, click the Hardware tab and click the Device Manager button in the corresponding tab page to enter the system's device list interface;

In the interface, expand the network adapters item, and then right click the network adapter option below the item. From the pop-up right-click menu, perform the Properties command, open the properties settings interface for the NIC, click the Resources tab in the interface, go to the label page, and on the resource settings for the page, select Interrupt Request Project, and then cancel the "Use automatic settings" check state; next click on the "Change Settings" button, then we can reassign the appropriate IRQ values for the NIC, when the "Conflicting device List" does not indicate a conflict occurs, it indicates that we manually assigned to the network card IRQ value is valid, At this point, just click the OK button to exit the Network Card Properties Settings window, and then restart the computer system, you can eliminate the network card resource conflict failure.

From the wire, make sure the connection is secure.

The network connection cable own quality as well as the production level of the net wire, will also have the certain influence to the network card work performance, many network cards cannot stabilize the work the fault is because the network cable quality does not pass or the network cable production nonstandard causes. To this end, in the production of network cable before, we must choose the quality of the better cable and Crystal head; In the production of cable connectors, not only to ensure that the crystal head in the metal chip and the wire inside the core line close contact, Also make sure that the data lines inserted into the crystal Head are in line with the international cable production standard such as 568A or 568B. After doing well the network cable connection, must ensure that the network card interface and the network cable connection can close contact.
