以太网上的互联网连接经常断开

我的有线局域网 (以太网) 网络连接经常中断，但无线网络工作正常，没有任何问题。这不是互联网速度的问题，因为互联网在 Windows 中工作正常。

你的以下言论引起了我的怀疑消息输出：

我会尝试以下操作：这只是一次尝试，如果没有产生预期的结果，只需关闭电脑然后再次打开，您就会遇到与试用前相同的情况。

  1. 阻止虚拟机，彻底杀死 VMWare。
  2. 阻止网络管理器（sudo service network-manager stop）；
  3. 手动连接（sudo dhclient eth0）。
  4. 尝试导航一段时间，看看是否会出现同样的问题。

让我们知道。
