In Windows 7 64-bit system, the network card driver problem has always been a headache. In fact, the solution is very simple. Just install it in administrator mode and the problem will be solved.
The specific questions are as follows:
The system is installed with 64-bit WINDOWS 7 Home Premium. Everything is normal when it boots up. You can access the Internet at the beginning. After a while, you restart the machine and suddenly you can’t access the Internet. Go to the device manager to see that everything is normal with the network adapter, and then use the system automatically. It was reported that there may be a problem with the local connection adapter driver. I reinstalled it from the original driver disk of the motherboard (ASUS P7P55D), but it still didn't work. I downloaded the 64-bit driver from the ASUS website, but it still doesn’t work after installing it. What’s the problem?
Solution:
Open windowssystem32logfiles. If you see the wmi folder, right-click on the wmi folder, click Get Administrator Permissions, and then restart the computer to dial up the Internet.
