System upgrade When we upgrade the operating system, there may be a lack of network card drivers in the Win7 system. This is because the upgraded operating system needs to be with a higher version.The network card driver is compatible, but the existing network card driver may not be supported at present, resulting in the inability to connect to the network. III. How to solve the problem of lack of network card driver in Win7? To solve the problem of lack of network card driver in Win7, we need to find the correct network card driver and install it correctly on the computer.
