Ubuntu (Mate) 16.04 无线和 LAN 不断断开连接

Ubuntu (Mate) 16.04 无线和 LAN 不断断开连接

编辑

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。
