我无法在 Ubuntu 16.04 的新桌面上连接到互联网
jh@jh-System-Product-Name:~$ mii-tool

这是什么意思？
我已经检查了驱动程序和路由表

遵循吉尔斯的建议
sudo mii-tool

这意味着什么？我用 ethtool 得到了这个
sudo ethtool enp3s0

What should I do now?
答案1
正如它在手动的：
SIOCGMIIPHY 关于“eth？”失败：不允许操作
大多数内核限制对 root 的访问。
您需要mii-tool以 root 身份运行，例如使用sudo mii-tool.
一般来说，“不允许操作”表示权限问题，与文件权限无关。通常这意味着您需要成为 root。
