我的另一台笔记本电脑也存在这个问题，它有一个不同的以太网卡。我认为问题不是出在 Ubuntu 本身。
但值得注意的是，在我的另一个家里，Ubuntu 互联网可以使用。而且这里的互联网在两台启动 Windows 的笔记本电脑上都可以使用。
每次我接近解决方案时，这个问题就变得更加复杂。有人知道是什么导致了这种奇怪的行为吗？
问题
无线的：我已连接到家庭网络，30 秒内一切正常，但不久后连接断开，chrome 中出现以下错误：
server DNS address could not be found.
Try:
Checking the proxy, firewall, and DNS configuration
DNS_PROBE_FINISHED_BAD_CONFIG
当我重新连接时，它又可以工作大约 30 秒，这是一个无限循环。
局域网：起初我的有线连接根本无法工作。经过大量的 Google 搜索，我使用以下线程中的代码让它工作： 17.04 上的 LAN 无法正常工作
sudo touch /etc/NetworkManager/conf.d/10-globally-managed-devices.conf
sudo service network-manager restart
但是有线连接现在有与无线相同的问题。它也会在短时间后停止工作，并在 Chrome 中出现相同的错误。但是，使用有线连接，我仍然可以访问并浏览我在同一会话中加载的所有网站页面。这让我得出结论，新的 DNS 在给定时间后就会停止工作。
