Here is another post in [Solved] category . I believe the proposed solution will work on all flavor of Linux system. But I have encountered the “Problem” and found “Solution” on OpenSuse – 12.1.
After installation of OS , I was shocked to see that the Realtek ethernet device is not recognized by OS. I suspected that , probably the required driver is not installed/available with OS. So I followed the below explained steps and hit the solution. You must be logged in into the system with root credential to do this exercise.
- Make ifconfig eth0 up.
To know the device name we can see the hardware detail of system OR make eth0 device up by below command.
$ ifconfig eth0 up
- Check device name.
open the file with “vi /etc/sysconfig/network/ifcfg-eth0”. In this file device name will be listed as bellow “NAME=’RTL8101E/RTL8102E PCI Express Fast Ethernet controller’ “
- Find Driver for Ethernet Controller.
The above step gives me enough clue that, I need to search for driver of Realtek ethernet controller. Which leads me to the below link.
Download Realtek Ethernet Controller Driver : click here
- Downloaded driver.
Download the tar.bz file and unzip.
- Run autorun.sh
Go inside the unzipped folder and we shall find file – named “autorun.sh”. Execute the shell file with below command.
- Reboot your system.
This should make your system’s ethernet device up and running
