After upgrading win10, the wired network card can not be used. The solution is

What should I do if the wired network card cannot be used after upgrading the win10 system? Recently, some users have upgraded the win10 system and found that the computer will display the normal display but the wired network card cannot be used. The plug-in network line is intermittent, and occasionally the connection is being connected to the internet, and then the cable is gone. By connecting to the router to view, the electrical signal passes normal, and then confirmed by the U disk system, the network card is normal, so it is suspected that the driver related problem. So how to solve it? Let's take a look at the solution together!

Solution:

1, after passing the exclusion, I have already suspected that it is a driver problem, check the documentation, it should be updated to win 10, and you can't roll back the driver. I have not used the previous win 8 driver under the official website. I thought that I should delete all the installed drivers and try again.

2. First, we tried to delete the previous driver file, this computer "Properties" Device Manager "Wired Network Card" right click "Driver" driver details.

3, find the detailed location of the driver file.

4, disable the faulty network card.

5. Delete the file we found in the third step. To do this, you must disable the network card and close all the windows manager windows.

6. Uninstallation (this step is suspected of not being done).

7 At this point, our NIC driver is gone, showing that the wrong driver is installed. We can install the driver, I suggest it is best to go to the device manufacturer's official website to download the relevant driver, I am directly updated.
