I have a desktop computer with a GA-E240N GIGABYTE Motherboard and running Kubuntu 12.04. On this computer I connect to the internet by wire. Because of stormy weather I decided to unplugged the internet cable and not use the computer the for the entire weekend.
On Monday I turned on the computer and my internet connection was gone. I was able to connect wireless from my laptop but the wired connection didn't work (not even on my laptop).
After changing the cable I was able to connect with my laptop by wire both booting from windows and Kubuntu (12.04) so this ruled out the chance of being a cable/router issue, however I haven't being able to get my desktop connection back again.
At the moment when I boot network manager says
setting network address, but after it fails it says
Cable Unplugged. It tries a couple of times but fails.
So far I have tried :
/etc/network/interfacesas suggested here : (Network is not working anymore - Ubuntu 12.04).
Configuring through Network Manager.
/etc/NetworkManager/from my laptop to my desktop (as suggested in the link pasted above).
Without any luck.
I have found many posts with similar issues but no solution to my problem yet.
Here is the output from
