Problems getting eth0 to come up


I'm not sure how long ago this happened but eth0 seems to have vanished from my computer. wlan0 works fine and when I plug into the switch there is carrier detect.

Code:
21:35:43 ~:$ ifconfig eth0 up
eth0: ERROR while getting interface flags: No such device
21:55:49 ~:$ lspci
....

07:00.0 Network controller: Intel Corporation Ultimate N WiFi Link 5300
After that i have no idea where to search for problems next, any ideas would be greatly appriciated (can't spell)

Ok, so far from what I know and searched, most likely you don't have the proper module loaded. Can you post lsmod?

Try this:

Code:
modprobe r8168
lsmod | grep r8
Post the output of the lsmod | grep command.

Ok, you will have to download the drivers and build from source. To save myself from a lot of typing, I am going to refer you to the ubuntu site:

http://ubuntuforums.org/showpost.php...4&postcount=10

There have been many problems encountered with the interface card you have, so I searched around and the link I posted should get you up and running. Report back if you keep having problems. Cheers,

Josh
