Dx 4000 Display show Network Disconnected

Thanks for your interest!! Yes I can toggle the lcd display thru several pieces of information. What is missing is the ip address that was there before. The four blue lights in the front are flashing. In the back where the net cable plugs in there is no light that I can see. I know enough about networks to be dangerous, could you explain better what is a USB nics? More than likely I don’t have any such item.
