Hi. I installed Ubuntu 11.04 on my laptop yesterday and using windows 7 at the same time. The multi booting you know.

But the wired network doesn't work at all when I boot with Ubuntu. Actually it didn't recognize the network connection

at the first place I was installing.

With windows, it works perfect. I surfed around in google for several hours, but couldn't find an answer.

Any suggestions?

Either provide the laptop model or the output of lspci as this is likely a driver issue

This is the line we care about. Since you're running a fairly recent Ubuntu, you should have an appropriately new kernel with support for this card built into the sky2 module that supports Marvell Yukon cards (to verify, ensure that sky2 is loaded into the kernel, a quick check is lsmod|grep -i sky). If it's not loaded, try loading it with sudo modprobe sky2.

Once loaded, list the output of sudo ifconfig -a to see if the interface is known by the networking subsystem.
