Intel 82562 or 82566 chipsets
From MEPIS Documentation Wiki
Some modern motherboards, e.g. in Dells, are using these chips which need the e1000 driver, but the version included with Mepis 7 does not work, either with the live CD or when installed. If you run lspci you may see this line:
00:19.0 Ethernet controller (Intel Corporation Unknown device 10c0 (rev02)
and the Interface tab of the Mepis Network Assistant shows
settings for eth0 -- status: does not exist
The solution is to install the later driver, 126.96.36.199 from Sourceforge; however you need to build it first, and before you can do that you need the kernel headers.
The easiest way to install the kernel headers is to follow these directions, provided you can connect with a wired connection. If not, download these headers on any computer with a working internet connection:

If you used this second method, navigate in Konqueror to the folder where you have put them, press F4 to bring up a terminal, become root, then type:
dpkg -i *.deb
You also need to create a symlink (see here for the reason), with this command:
ln -sf /usr/src/linux-headers-$(uname -r) /usr/src/linux
Download the driver source code from this page.
Then unpack the driver (right-click --> Extract), navigate to its src folder (e.g., /home/UserName/Desktop/e1000/src), and as root type:
Don't worry about the 'cannot write...in catman mode' error at the end.
Now you need to remove the earlier version and load the new one, so type
modprobe -r e1000; modprobe e1000
Run ifconfig and your ethernet should show up, or use the Network assistant.
