Hi Dan,
I'm sorry I do't have any help for you beyond what Tech Support at D-Link gave you, however, I do have a small Batch file that makes experimenting with internet configuration easy.
Here it is below. Copy this into a text file and save it as "IP.BAT" then open a Run window and enter the command "IP" (without quotes).
