Two common NIC driver failures and processing methods under win7 system

Fault phenomenon 1. After installing NIC driver, the boot speed is much slower than before
Cause analysis: Generally speaking, when the single machine is configured for the network, The system has detected the network card once more, which makes the system startup slower than before. This is normal. If you do not specify an IP address for the network card, the operating system will automatically search for an IP address assigned to it when it starts up. In about 10 seconds, the source of the fault is more in the matching of the network card driver and the transmission rate (that is, the connectivity type soft fault).
Solution: First of all, you need to eliminate the error during the installation of the driver. Even if the network card is not used, it is better to assign an IP address to it, or simply set it to off in the BIOS, which will increase the speed. A common countermeasure is to uninstall the driver and then reconfigure the NIC parameters.
Fault phenomenon II, NIC driver failure caused by anti-virus, abnormal shutdown, etc.
Cause analysis: When the anti-virus, abnormal shutdown and other reasons, it will also cause damage to the NIC driver, if the NIC driver is damaged, The network card can't work normally, and the network can't ping, but the network card indicator is glowing.
Solution: First click on “Start——Control Panel——System——Device Manager" in the win7 system to check if the NIC driver is normal, if “network adapter&rdquo If the NIC card icon is marked with a yellow exclamation mark, it means that the NIC driver is not normal. Just reinstall the NIC driver to solve the problem.
