我安装了 r8168 驱动程序包，但仍然不起作用当我输入时，lsmod | grep r8168它什么也没有返回。
在 Fedora 上它可以工作：
lsmod | grep r81*
r8169 94208 0

更新：我以为我需要 r8168 驱动程序，但结果发现我已加载了 r8169。无论如何，pppoeconf 没有加载（在我尝试对驱动程序进行一些操作之前），并且仍然找不到以太网卡。
答案1
驱动程序 r8168 仅涵盖三个特定设备。检查：
modinfo r8168
分别是 1186:4300、10ec:8161 和 10ec:8168。实际上，你的设备是这样的：
瑞昱半导体有限公司 RTL8101/2/6E PCI Express 快速/千兆以太网控制器 [10ec:8136]
您的 10ec:8136 设备不在本r8168-dkms_8.045.08-2_all.deb套餐的涵盖范围内，因此无法解决您的问题。
硬件设备的内核模块根据设备 ID（例如 10ec:8139）加载，以便不会为错误的设备加载错误的驱动程序。r8168 是错误的驱动程序。
