我是 Linux 新手，所以我不熟悉所有命令和设置。我已经安装了 LinuxCNC 的新副本，它捆绑在 Debian Wheezy 中。安装没有问题。我的有线局域网连接显示断开连接。我的路由器似乎可以从控制面板识别该设备，但 Linux 没有互联网连接。连接电缆后，LAN 端口上的指示灯会亮起并闪烁。
我遵循了一些编辑配置文件的指南，但没有运气。然后，我开始阅读本指南： RTL8111 Linux 驱动指南 但我无法将这台机器连接到互联网上以正确遵循说明。
- 1）如何诊断实际问题？（什么命令？）
- 2）我该如何修复它？

更新：我已经从这里下载了驱动程序：RTL驱动程序阅读自述文件，解压 tar 并运行 autorun.sh 文件。我没有收到任何错误。我重新启动了机器，我似乎取得了一些进展，我现在看到网络的连接图标，但我似乎并没有真正连接到网络。
我尝试过静态和 DHCP，但没有成功。奇怪的是，当我尝试静态 IP 时，“debian”出现在我的路由器的已连接设备列表中。我认为我已经有了正确的驱动程序设置，但仍然无法连接。
