Ubuntu 检测不到 eth0

Ubuntu 检测不到 eth0

我使用双启动 Ubuntu 14.04 / Windows 8.1。我格式化了 Windows,但 grub 没有捕获 Windows。所以我用了boot-repair除了一件事之外,它运行良好......

eth0我使用后Ubuntu 无法检测到boot-repair

Windows(通过双启动)和 liveUSB(Ubuntu)可以检测并使用以太网,但 Ubuntu 不能。

设置

$ ifconfig

$ cat /etc/network/interfaces

当我执行时dmesg | grep eth0,它没有显示任何结果。但是lspci | grep Ethernet有如下结果。

03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 0c)

我该如何修复它?
