Hi, I do not know if this is what you want to try but, the way i connected my D-Link print server was using my Belkin router. I wanted a wireless network as i have two laptops, i also wanted to print from the two printers that i had, from either computer without having to have both PC's switched on.
I connected the D-link print server into one of the ethernet ports on the back of the router. I configured the router to accept the print server and Bobs your uncle.
My D-Link print server was hard wired unlike yours. As far as i am aware you cannot connect to the internet using the print server. My Belkin router says something about the belkin print server and how easy it is to connect up.
Sorry for the negative response but the good news is that the cost of wireless routers are very inexpensive, hope this helps.
