Comment 22 for bug 147639

Your ethernet appears to be working, or at least it achieves link. What is suspicious in the dmesg log are several segfaults:

[ 153.541692] scim-bridge[5847]: segfault at 53454741 eip b7e97443 esp bf907e90 error 4

Can you boot the Live CDROM and see if you have network connectivity?
