有线网络接口随机上升

我正在使用桌面版 Ubuntu 18.04.3 LTS，我必须连接有线网线，我正在通过 WIFI 工作。但有时，当我工作时，我突然收到烦人的通知，说我的托盘中的 enp108s0 接口已启动（我尚未连接电缆）。如果我断开连接，它稍后会再次启动。我该如何修复它？

更新：sudo journalctl /usr/sbin/NetworkManager 给出以下内容：

虽然不完整，并且考虑到没有先前的警告，但意味着（对我来说）您的物理连接是间歇性的。

摇动你的网线，如果有任何移动或者网络出现抖动，请更换它。

答案2

拿一个手电筒，检查有线以太网插座中的插针。

在此处输入图片描述

被推入的异物可能会导致它们短路，从而导致您出现间歇性症状。
