有一天，我的网络在没有任何警告的情况下完全瘫痪了。我以为可能是调制解调器或路由器的问题（调制解调器有点不可靠，无法处理太多连接）；但问题并不出在这两个方面。
由于图形驱动程序混乱，我不得不重新安装 Linux 系统（这是我的错，我做错了一些事情，无法让它再次工作）。但我的有线连接无法连接到互联网。我确实有一个 IP 地址、子掩码、IPV6 地址，背面以太网端口上的灯正在用绿色和橙色 LED 传输数据，而且我的 WiFi 连接仍然正常工作。
我已经发布了我的 inxi 输出、syslog 和 ifconfig。如果有人能就此给我一些建议，那就太好了。
INXI-Fxn 输出如下：

你可以静态地通过执行以下操作设置您的 IP 地址 -
转至文件夹/etc/网络/
您可以看到一个名为接口
只需将其备份到安全的地方并在 gedit 中打开即可
最初该文件可能包含以下内容
auto lo iface lo inet loopback现在将以下内容添加到文件中
auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 192.168.1.108 netmask 255.255.255.0 network 192.168.1.0 broadcast 192.168.1.255 gateway 192.168.1.1 dns-nameservers 8.8.8.8 208.67.222.222输入所有必需的详细信息并保存文件（以上所有详细信息均为示例）
现在通过在终端中输入以下命令来重新启动网络服务
sudo service networking restart笔记：对于 wifi 你只需更换eth0经过wlan0
