本文介绍了在DELL_LATITUDE_E5440笔记本上安装ubuntu12.04后遇到无法上网的问题，通过查询得知网卡型号为e1000e，然后从Intel官网获取Linux驱动源码，编译并安装驱动，详细步骤包括下载驱动、编译安装以及加载模块。

Step 1. 查询该笔记本网卡型号，我查出的是intel的网卡e1000e ，直接上网找 Linux系统下的驱动源码，然后直接编译安装就ok。

Step 2. 找到驱动下载地址【http://www.intel.com/content/www/us/en/support/network-and-i-o/ethernet-products/000005480.html?wapkw=e1000e#over_e1e】

Step 3.Building and installation

To build a binary RPM* package of this driver, run "rpmbuild -tb e1000e.tar.gz".

Notes

For the build to work properly, the currently running kernel MUST match the version and configuration of the installed kernel sources. If you have just recompiled the kernel, reboot the system now.
RPM functionality has only been tested in Red Hat distributions.

Move the base driver tar file to the directory of your choice. For example, use "/home/username/e1000e" or "/usr/local/src/e1000e".
Untar/unzip the archive, where <x.x.x> is the version number for the driver tar file:

tar zxf e1000e-<x.x.x>.tar.gz
Change to the driver src directory, where <x.x.x> is the version number for the driver tar:

cd e1000e-<x.x.x>/src/
Compile the driver module:

# make install

The binary will be installed as:

/lib/modules/<KERNEL VERSION>/kernel/drivers/net/e1000e/e1000e.[k]o

The install location listed above is the default location. This may differ for various Linux distributions.
Load the module using either the insmod or modprobe command:

modprobe e1000e insmod e1000e

Note that for 2.6 kernels the insmod command can be used if the full path to the driver module is specified. For example:

insmod /lib/modules/<KERNEL VERSION>/kernel/drivers/net/e1000e/e1000e.ko

With 2.6 based kernels also make sure that older e1000e drivers are removed from the kernel, before loading the new module:

rmmod e1000e; modprobe e1000e
Assign an IP address to the interface by entering the following, where <x> is the interface number:

ifconfig eth<x> <IP_address>
Verify that the interface works. Enter the following, where <IP_address> is the IP address for another machine on the same subnet as the interface that is being tested:

ping <IP_address>

Note

Some systems have trouble supporting MSI and/or MSI-X interrupts. If you believe your system needs to disable this style of interrupt, the driver can be built and installed with the command:

# make CFLAGS_EXTRA=-DDISABLE_PCI_MSI install

Normally the driver will generate an interrupt every two seconds, so if you can see that you're no longer getting interrupts in cat /proc/interrupts for the ethX e1000e device, then this workaround may be necessary.
