  • 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.

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.

  • I can add the optional solution - usually there is older kernel with headers and extra and with the internet working. At the boot time choosing previous kernel. So, it is not necessary to search another way to download installation files.
