I've had exactly the same problem, however just found the solution: In the Gusty Tribe 5 live installer, open a terminal:
$ sudo su # rmmod forcedeth # modprobe forcedeth msi=0 msix=0 # /etc/init.d/networking restart Your network interfaces should come back up and actually work now :-) -- Ethernet (nVidia MCP55) is not working on Gusty Tribe 5 https://bugs.launchpad.net/bugs/136836 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
