以太网在 Ubuntu 16.04 Dell Vostro 上无法正常工作

我有一台戴尔 Vostro 3446，双启动，安装了 Windows 10 和 Ubuntu 16.04。以太网在 Windows 上可用，但在 Ubuntu 上不可用，而且我在戴尔官方网站上也找不到适用于 Ubuntu 的以太网驱动程序。它以前可以正常工作，但最近我不得不格式化并重新安装 Windows 和 Ubuntu。

ifconfig -a 的输出如下：-

答案1

您的以太网无法启动，因为驱动程序未按预期自动加载。首先，让我们看看是否能确定原因。它是否被列入黑名单？从终端检查：

grep r8169 /etc/modprobe.d/*

如果您找到结果，请发布它，我会编辑此答案以建议更正。

我们可以使用以下命令自动加载驱动程序：

sudo -i
echo r8169 >> /etc/modules
exit

一切已准备就绪。
