使用 Realtek 的 Ubuntu 中 LAN 无法工作

我的 Ubuntu 上的互联网无法使用，但 Windows 上的互联网可以工作。

我知道我的驱动程序是 Realtek。

编辑

重新安装 Ubuntu。

当我编辑时互联网正在运行/etc/resolv.conf

从

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 127.0.1.1
search home

到

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 127.0.1.1
search home
nameserver 8.8.8.8
nameserver 8.8.8.4

我怎样才能让我的互联网永久正常工作？
