cannot connect to wireless router but can access internet

Help,

I bought a new computer (with vista home premium) and although I can connect to internet I cannot access the configuration page (192.168.0.1) of the router ( Dlink DI-540 - although I still can with my old computer).

I tried reseting the router to see if it was somehow "married" to my old computer but didn't work....some clues?

I copied below the details the ipconfig details (deleted a couple of information):
