If the lspci output isn't always the same it might really be a hardware 
problem. I would suggest you try these commands in a terminal to reload 
the module for the card and check for error messages:

sudo rmmod r8169
sudo modprobe r8169
dmesg

At the end of the dmesg output there should be the messages from 
restarting the module. Are there any errors? On my machine it looks like 
this:

[14958.665839] ACPI: PCI interrupt for device 0000:06:07.0 disabled
[14964.285809] r8169 Gigabit Ethernet driver 2.2LK loaded
[14964.285972] ACPI: PCI Interrupt 0000:06:07.0[A] -> GSI 20 (level, 
low) -> IRQ 21

[14964.342191] ADDRCONF(NETDEV_UP): eth0: link is not ready

There is no cable connected here, thats why there are the "link down" 
and "link is not ready" messages.
