Have you tried removing the virtual interface that is setup there (eth0:avahi) then reconfigure dhcp?

Also, are you at least getting out to your gateway? public interface of your router? gateway the router is going to?

[PedalsV8]

I have a work around that seems to work ok
If you dual boot Windows on some systems. Windows by defaults disables the NIC at Windows shutdown time in order to disable Wake-On-Lan, and this NIC will remain disabled until the next time Windows turns it on. The r8139 driver in the kernel does not know how to turn the NIC on from this disabled state; therefore setting windows to wake on LAN will leave the NIC on so when you boot into Ubuntu it will then connect

Check your BIOS also, there might be an option for "Wake on Lan". I think if you enable that, you will accomplish the same thing.
