Ubuntu(Windows 双启动):Wifi 正常,但浏览器无法保持连接

Ubuntu(Windows 双启动):Wifi 正常,但浏览器无法保持连接

这是我在这里的第一篇帖子。请耐心听我说:我对 Ubuntu 和编程都还很陌生。

我在 Lenovo IdeaCentre AIO 510 上安装了 Ubuntu 16.04 LTS。我的 Wifi 似乎连接得很好。在使用 Ubuntu 之前,我的连接通常很好,在 Windows 中从未遇到过任何问题。但是,我在 Ubuntu 中安装了 Firefox 和 Chrome 浏览器,两者都经常停止连接到互联网。有时只持续几秒钟,有时最多持续 10 分钟左右。然后它会重新连接,几分钟后经常再次断开连接。

我知道有很多问题与我的问题类似,但是我尝试了几种推荐的解决方案,但似乎没有任何效果。不管怎样,我想在一个单独的问题中发帖。

请告诉我我可以为您提供哪些信息。我将从以下内容开始:
