今天我收到了一台全新的 Dell OptiPlex 7080，并在上面安装了 Oracle Linux 7。该机器具有外部无线天线和以太网端口。无线天线工作，但以太网端口不工作。
当我运行时，lshw -class network我得到以下输出，显示以太网控制器未被声明：

如果我运行，lspci -v我会看到 Wi-Fi 控制器和以太网控制器。前者有一个内核模块（正在使用），后者什么都没有：

互联网建议 e1000e 是该以太网 I219-LM 控制器的驱动程序。如果我运行lsmod | grep e1000e此命令，则不会显示任何结果。我可以加载驱动程序，modprobe e1000e然后它会显示在 中lsmod，但网络设置 GUI 不允许我选择有线连接。我也没有看到任何错误dmesg | grep e1000e；仅版权声明。
我尝试从 USB 运行 Ubuntu 20.04 LTS 的实时版本，Ubuntu 确实识别了我的以太网控制器，所以我不认为这是一个硬件问题。
解决这个问题的最佳方法是什么？
