安装 16.04LTS 后无网络连接

在全新安装的双启动 win7/16.04LTS 上。互联网在 Windows 上工作正常，但在 ubuntu 上没有有线或无线连接。它只会尝试永远连接。我无法 ping 通谷歌，我甚至无法通过 192.168.0.1 上的浏览​​器连接到我的路由器

所以我将其添加到 /etc/network/interface

auto enp5s0
iface enp5s0 inet static
address 192.168.0.105
netmask 255.255.255.0
gateway 192.168.0.1
dns‐nameservers 8.8.8.8 8.8.4.4

然后它显示了一个 IP，我运行了这些

ifconfig=

任何帮助都将不胜感激谢谢

问题是我的以太网适配器根本没有被驱动。我发现 realtek 网站只提供适用于 Linux 内核 3.x 或更早版本的驱动程序，所以我安装了 14.04 并安装了驱动程序，现在它在线了。
