我的 Acer Aspire F15 笔记本电脑上的 Ubuntu 16.04 出现了一些非常奇怪的行为，仅当连接到一个 WiFi 网络时才会发生（在其他方面，它运行得很好）。
更新 01.07.2017
这很可能是浏览器的问题。
今天我在 Facebook Messenger 上接了一个电话。通话过程中，我打开了 Mozilla（使用 Chromium 工作），突然间，我无法在两个浏览器中加载任何页面，但通话仍在继续，没有中断。（此外，Dropbox 图标指示器显示它已连接到互联网）。
我后来测试了一下，Chromium 运行正常，但打开 Mozilla 后，我无法再加载任何页面，无论是在浏览器上还是在其他地方。这是什么问题？
行为描述
Ubuntu 启动后，互联网就可以正常工作：
❯ ping -c5 google.com

但是我启动 Chromium（或 Firefox）后，互联网无法工作：
❯ ping -c5 google.com
ping: unknown host google.com
然而，如果我将它放置 3-5 分钟，它就会再次开始工作。有时，它可能会一直工作直到我关闭笔记本电脑，但有时它可能会再次停止 3-5 分钟，然后恢复工作。
