This is my first post and I'm fairly new to Ubuntu.
I'm running 10.10 on an integrated mini-ITX board, the Asus at3iont-i deluxe. On my first install, everything worked out of the box, and I was able to setup all I wanted, with valuable help from http://ubuntuforums.org/showthread.php?t=1458300 .
For various reasons, I did a complete reinstall of 10.10, and after that my onboard Ethernet adapter is completely unresponsive. When I plug it in, the little light on the router does not indicate a connection (but it does if I put my laptop on the same cable).
The Gnome NetworkManager does not show a connection. I'm not sure what to check, but
lspci | grep Ethernet
04:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 03)
and both and give error messages about eth0 being unknown or not configured.
eth0 Link encap:Ethernet HWaddr 20:cf:30:bb:67:87

Any help would be greatly appreciated. Oh and by the way, the onboard wlan works fine.
