无法在戴尔笔记本电脑 E7470 上访问以太网和 wifi

我有一台新的 DELL Latitude 7470，装有 Ubuntu 14.04。我无法在笔记本电脑上使用 WIFI 甚至以太网，但使用 USB 网络共享可以上网。我认为这可能是驱动程序问题。

显示lshw -C network以下输出

该lspci命令显示以下输出

该命令sudo ubuntu-drivers devices根本没有显示任何输出，也没有给出任何错误。

请帮助我。谢谢

我也遇到了同样的问题，同样的电脑，同样的操作系统。目前我仍在调查此事，但看来内核版本 3.19.0.68 在某种程度上是造成此问题的原因。

作为临时解决方案，在启动时当显示 Ubuntu 徽标时按 ESC，选择“高级选项”，然后选择另一个版本的内核（例如 .30 可以完美运行）

一旦我找到永久的解决方案，我就会将其发布在这里。
