I have a first gen ds phat that finds and connects to wi fi fine, (its a d-link DI-624) I just got a ds lite that can find the AP but does not connect, no matter what i do, -turning off wep (i kno, ascii wep does not work) -turning off mac filtering -enabling static ip -enabling dynamic ip did Nintendo wized up and decided to make people pay for a Nintendo wi-fi usb connector ? or is it just luck of the draw whether wifi works ? does your ds lite work with your router? do you have more than 1 ds connected to your router ? sigh.
