Hello,
I am living in Munich, first off all I apologize for not writing in german because my german is very bad.
I am having dual os (windows 8.1 and ubuntu 14.04 LTS). In ubuntu my ethernet wired connection is not working but wifi and in windows it works flawlessly.

I tried the following
sudo dhcpclient eth0: terminal got hanged and I didn't get any response
2. I also tried editing the gksu gedit /etc/network/interfaces by adding lines for eth0. But after that my wired was not recognized at all, before that I was atleast able to see the ip address in connection information, therefore I removed those lines.
3. Tried downloading the compat-drivers-2013-03-04-u.tar.bz2 but make throwed the following error
error "ERROR: compat-drivers by default supports kernels >= 2.6.24, try enabling only one driver though"
4. Even replaced new cable, but no use.
