好的，我尝试按照我能找到的每个示例操作，但都不起作用。我需要你的帮助。有一天，更新来了，我的以太网丢了。版本升级失败最终导致重新安装 15.04，然后我升级到 15.10。在每个版本中，我都尝试下载当前的 Realtek RTL8101E 驱动程序（我也尝试过从 realtek 网站下载 r8169）。我可以加载 r8101 模块，但我甚至无法通过有线连接 ping 我的路由器。无线正在 ath9k 驱动程序上运行。以下是一些详细信息：

答案1
sudo dhclient
如果您多次使用过网络共享软件或热点等，此命令将有助于彻底修复它。我从另一篇文章中得到了这个命令。这对我有用
但是首先，输入，这将帮助您找出您的硬件在系统上的注册方式。在第一个块中查找第一个，例如我的名为 enp3s0。
是否配置
