已连接到有线网络，但互联网无法正常工作 Ubuntu 17.04

有线网络显示已连接，但互联网不起作用。

sudo lshw -C network

终端显示以下内容：

我也尝试过禁用安全启动，但是也不起作用。

上面ifconfig显示：

注意：）在提问之前，我已经阅读了这里大部分类似的帖子/问题。这些都不适合我

请帮我解决这个问题。

答案1

What happens when you do the following?

sudo /sbin/modprobe -v -r r8169
sudo /sbin/modprobe -v r8169

If your r8169 comes back into service, then:

Had your machine previously suspended?  That is a well-known weakness

在 r8169 内核对象中：由于某种原因，suspend 后跟 resume 似乎禁用了 r8169 驱动程序，这种情况可以追溯到几年前。
上面的 2 条命令行解决了这个问题。
我最终创建了一个 systemd 服务来自动为我的笔记本电脑解决这个问题。
