Two common NIC driver failures and processing methods under win7 system

Symptoms 1. After installing NIC driver, the boot speed is much slower than before

Cause analysis: Generally speaking, when performing single machine After the network configuration, because the system has detected the network card once more, the system startup is much 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. It takes about 10 seconds, and the source of the fault is more than 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. Speed, the most common response is to uninstall the driver and then reconfigure the NIC parameters.

Fault phenomenon 2, NIC driver failure caused by anti-virus, abnormal shutdown, etc.

Cause analysis: When the anti-virus, abnormal shutdown, etc., it will also cause damage to the NIC driver. If the NIC driver is damaged, the NIC will not work properly, and the network will not ping, but the NIC indicator will be lit.

Solution: First click on “Start——Control Panel——System——Device Manager" in the win7 system to check if the NIC driver is normal, if “ The network adapter icon shown in the network adapter is marked with a yellow exclamation mark, indicating that the NIC driver is not normal, just reinstall the NIC driver to solve the problem.
