After the installation, the network can be connected, but only through wireless connection. when connected to the wired network, the port does not shine at all. then I wonder if this network card is not identified or not, however, I am not very familiar with it, so I did not dare to give a comment, so I lost some commands on the terminal to view the relevant information.
