  • What did you do before this happened? Did you install any kernels? – Pilot6 Jan 24 '17 at 20:59
  • Actually , I don't remember , the issue from long time. – Rabab Zein Jan 24 '17 at 21:01
  • Please hook up the ethernet and run the command: sudo modprobe r8169 Now does ethernet appear in the Network Manager icon? Please then run: ifconfig and post the result. – chili555 Jan 24 '17 at 21:04

Please download these packages on some other computer: http://security.ubuntu.com/ubuntu/pool/main/l/linux/linux-image-3.13.0-70-generic_3.13.0-70.113_amd64.deb

http://security.ubuntu.com/ubuntu/pool/main/l/linux/linux-headers-3.13.0-70-generic_3.13.0-70.113_amd64.deb

http://security.ubuntu.com/ubuntu/pool/main/l/linux/linux-headers-3.13.0-70_3.13.0-70.113_all.deb

http://security.ubuntu.com/ubuntu/pool/main/l/linux/linux-image-extra-3.13.0-70-generic_3.13.0-70.113_amd64.deb

Transfer them on a USB key or similar to the desktop of the Ubuntu computer. Now, in a terminal:

sudo dpkg -i ~/Desktop/linux*.deb

Reboot.

Post back any errors or missing dependencies. Once we have networking, we will have additional steps.
