The title says it all, I freshly installed Lubuntu 12.10 and it isn't able to connect to the intranet and/or internet. Actually, it is working randomly, if I restart the computer 2-3 times, it might work 1 time.

But it's now booted up and not working. Here's what I got from lspci, lsmod and ifconfig:

The computer is a old Lenovo/IBM M52 Thinkcentre with an Intel E6400 dual core, 2GB of RAM and a GMA950 IGP chip. What's wrong with the ethernet?

Please note that Windows 7 and Windows XP are also installed on the same 40GB SSD and booting correctly from GRUB, both work correctly with my ethernet card. On my switch, I can see the light is green on this IBM computer's port whether I'm in XP, 7 or Lubuntu OS.

Please note that I'm not a linux guru or whatsoever, I consider myself a noob and I'm trying to do my best to learn.

I had assigned a fixed internal IP address on the DHCP server to that computer. If I remove the assignation, it works fine. Because I don't really need the fixed IP address, I assume my problem is now solved.
