Two common network card driver faults and their treatment methods under Win7 system

Failure phenomenon one, the installation of network card driver after the boot speed is much slower than before

Cause analysis: In general, 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 normal phenomenon, if you do not specify IP address for the network adapter, the operating system will automatically search for an IP address assigned to it at startup, which takes about 10 seconds, The fault source is more in the match of the driver and transmission rate of the network card (that is, the connected soft fault).

Workaround: First of all, you need to eliminate the installation driver error, even if the network card is not used, it is best to assign IP address, or simply in the BIOS set it to shut down, so you can improve speed, the most common response is to uninstall the driver, and then reconfigure the network card parameters.

Failure phenomenon two, anti-virus, abnormal shutdown and other reasons caused by the network card driver failure

Cause analysis: When anti-virus, abnormal shutdown and other reasons, will also cause the network card driver damage, if the network card driver damage, Nic will not work, the network also ping impassability, but the NIC led is luminous.

Solution: First click on the win7 System "start-control Panel-system-Device Manager" to see if the NIC driver is normal, if the network adapter displays a yellow exclamation mark on the NIC icon, the NIC driver is not normal, just reinstall the NIC driver. can solve the problem.
