Common faults and solutions for installing NIC drivers

1, the installation of network card driver after the boot speed slows down

Failure phenomenon: The installation of network card driver Restart the computer, found that the boot speed significantly slower than before.

Troubleshooting: First troubleshoot the installation driver during the error. Generally speaking, when a stand-alone network configuration, because the system more than once to the network card detection, making the system start slower than before, this is a normal phenomenon.

Also, if you do not specify an IP address for the NIC, the operating system automatically searches for an IP address assigned to it at startup, which takes about 10 seconds. Therefore, even if the network card is not used, it is best to assign IP address, or simply set it in the BIOS to shut down, so as to improve the start speed.

The problem summary: After adding network equipment to a single machine, the startup generally will be slower, of course, if the system start a long time to stop before you have to pay attention to check.

This article summarizes: the network card class fault occurs in the net hardware frequency is still relatively few. It is concluded that the fault source is more in the match of the driver and transmission rate of the network card (that is, the connected soft fault); The usual solution is to uninstall the driver and reconfigure the NIC parameters.

2. Network card driver Fault resolution method

Due to anti-virus, abnormal shutdown and other reasons, may cause the network card driver damage. If the NIC driver is damaged, the NIC does not work properly, and the network does not ping, but the NIC LEDs glow. You can see if the NIC driver is normal by using the Device Manager option in the System in Control Panel, and if the network adapter icon is labeled with a yellow "!", the NIC driver is not normal, reinstall the NIC driver, you can solve the problem.

3, unload stubborn network card driver

My computer is connected through the school intranet, the host's PCI slots are installed with the NIC and sound card, because to replace the chassis, so all the reinstall, also do not remember the original NIC is inserted in the first few PCI slots above, so casually install the NIC on one of the PCI slots.

After entering the Win2000, the system automatically found my network card, but after the original network card name added "#2" logo. After use, found that can not access the Internet, view the "Network Neighborhood" attribute, found that all of the IP what is not set, but all set again, can be the result is still not online. At this time I began to suspect the name of the network card, is not the original network card unloaded, and now found a new network card "conflict"?

Right-click My Computer to select properties and click hardware → Device Manager to view the network adapter. But only the back with a # card, click on the menu "View" in a "show hidden device", still no original network card equipment appeared, then how can I delete it? Is it only open the chassis to change the position of the network card slot?

Open the Control panel and suddenly notice that there is a "Add/Remove Hardware" item, double click to run, click "Next", select "Uninstall/Unplug Device", and then click "Uninstall Device", the dialog box lists the list of hardware that needs to be unloaded, and the following "Show hidden Device" is hooked, hey, I found my original network card name (No sign of the signs), remove it! Go back to the system properties in Device Manager, select operations → scan hardware changes, the network card found after the number of no #. Finally to the "Network Neighborhood" properties in accordance with the original setup steps, reset IP and gateway and subnet mask, as well as DNS, open IE check, ok! connected.

The network card "fault" give me a little experience: if in the WIN2000/XP, the network card device changes, it is best to first remove the NIC from the device Manager, to avoid the problem of installing the NIC again.
