I'm not sure if the drivers are installed correctly. I ran an update on the marvel yukon, and I am connecting to the internet. I can say that Client for Microsoft Networks is in the list for each of these, as well as for the 1394 net adapter, which is connected.
As far as which adapter is being used, the Nvidia one has no cable plugged into it and says 'network cable is unplugged.' I have the router plugged into the marvel yukon. Here are those texts, I'm also including a screen of the network connections:
