I too could not connect to shareport printer with a new laptop running win 7 64b & shareport 3.0 , DIR-655 A4 f/w 1.21 "No device servers" error. My two other machines running XP 32b had no problem using shareport v 1.14. Somewhere on these forums it was suggested shareport version 1.17 worked with Win 7 . So I googled it, selected this page http://dlinkedrouter.org/2010/07/18/shareport-1-17-for-windows/ , downloaded it , deleted version 3.0 , installed v1.17 , printer was found and recognized instantly and printing is perfect.. After pulling my hair out and thinking about this problem for four months, I found the solution simply through someone elses success so I just wanted to add my two cents. Hope this helps one of the many who are experiencing this problem.
