我用的是 Windows，后来决定使用 Ubuntu 并安装在我的电脑上。但网络不工作。我研究了这个问题，并得出了以下结果。

我见过很多类似的帖子，但是都没有解决。
我尝试过更新驱动程序，使用 bootutil，但都不起作用。有什么解决办法吗？
bootutil的结果如下。
$sudo ./bootutil64e -NIC 1 -defcfg

答案1
您的 Intel 82579LM 千兆网络连接的 NVM 已损坏。
英特尔® 以太网闪存固件实用程序 (BootUtil) 用于更新配置并对受支持的英特尔 PCI 和 PCI-Express 网络适配器的闪存上的 PCI 选项 ROM 进行编程。
请从下载英特尔实用程序来修复此问题这里，阅读附带的文档和网站上的文档，然后执行以下操作......
cd APPS/BootUtil/Linux_x64
chmod +x ./bootutil64e
sudo ./bootutil64e -NIC 1 -defcfg
来源：https://downloadcenter.intel.com/download/29137?v=t
更新＃1：
由于此 bootutil 错误：
ERROR: -DEFCFG not allowed when combo image is present in flash
尝试sudo ./bootutil64e -NIC=1 -UP=Combo或从下载 Windows 更新程序这里并从 Windows 执行此操作。
更新 #2：
Windows 更新程序从以下位置下载这里。
答案2
我已经通过安装英特尔网络适配器的完整驱动程序解决了https://downloadcenter.intel.com/download/22283/Intel-Ethernet-Adapter-Complete-Driver-Pack?product=47620。然后重新启动 ubuntu，它运行得非常好。
答案3
要安装英特尔驱动程序，我建议也从 sourceforge 下载它们： https://sourceforge.net/projects/e1000/files/e1000e%20stable/3.8.7/ 最新版本 3.8.7 在英特尔网站上不可用。在运行命令“make install”之前，请确保安装：
sudo apt 安装 build-essential
这将避免错误 2
