I've reinstalled a few times now, tried the r8168 driver and still very similar results.
When I swap the network interfaces the r8169 PCI card becomes the external card and it kinda works, the lights at the back of the card come on and ping works although it is very slow. Swap back and the r8169 dies, no lights no ping nothing.
Is it possible that something in LMCE broke something somewhere with the network setup, esp if everything was pnp before? (A lot of somethings there)
If so how do you roll back?
Can I install an older snapshot and not run apt-get update and upgrade?
