I installed Kubuntu 12.04 few days ago on my new ASUS laptop. Right after the installation wired connection was not detected, but wireless worked just fine. So, I was able to get the latest updates, and after that both wired and wireless worked ok.

Yesterday I just wanted to see what happens if I boot in a previous version of Linux (I have that option at boot), and it booted, but network wasn't worked at all, neither wireless nor wired.

The problem is now network isn't working even if I boot normally, the lastest version. I'm a newbie in Linux / Ubuntu, so I don't know what specific information should I provide more and how I find it, but I'll try to do it if someone guide me.

All you need to do is reconfigure the Latest Kernel image. Linux kernel work in our PC's to maintain the proper functionality of hardware with OS.

Find out the what is the latest kernel Image.

To do that the best way is installing synaptic package manager.
