仅显示以太网和网络控制器描述

出于一些研究目的，我尝试在我的 Ubuntu 12.04 LTS（最初有内核 3.2）上安装不同版本（3.13.6）的 Linux 内核。问题是当我使用 3.2 内核时，以太网工作正常，并lspci -v显示以太网控制器正在使用内核驱动器：r8168。当我重新启动系统并使用 3.13.6 内核启动系统时，我被卡住了等待网络配置事情。当主屏幕出现时，我无法登录我的帐户（因为登录需要互联网访问）。因此，我必须使用 GUEST 帐户登录，而这不授予我任何用户权限sudo。

其次，当我使用我的访客帐户使用lspci -v命令时，我看到以太网控制器有可用的 r8168 和 r8169 模块，但没有一个被用作驱动程序。我尝试了多种方法，但问题是我无法访问互联网sudo。

sudo当我使用 3.2 内核版本登录时，我可以访问互联网。有什么方法可以将 3.2 Linux 内核中的某些内容移植到 3.13.6 内核中来解决这个问题吗？

这些代码片段，尤其是 LSPCI -V 表明我的内核 3.13.6 具有可用于以太网控制器的驱动模块，但没有使用，因为它应该提到类似“内核驱动程序正在使用：_____”的内容：
