我的以太网几天前运行正常，直到我注意到这种奇怪的行为。
这是一个循环：
- 互联网工作正常全速（75 Mbps）。
- 现在它变得无响应. 甚至无法 ping google.com
- 又开始了在职的全速运行几分钟。
- 现在停止并变得无响应再次。
我重新安装了网络驱动程序：sudo apt --reinstall install r8168-dkms
但一切还是一样的。
说实话我根本不知道这是什么原因造成的。
没有把握从哪儿开始寻找错误。
基本信息：
结果ifconfig：https://pastebin.com/FHRS25zb[enp6s0 是我的网络。我使用 Cloudflare DNS]
