You have to configure the wireless section of the router to be a Wireless access point. The router is set up to bridge between the wireless antenna and the wan port. You have nothing plugged into the wan port and this is why you connect but do not get on the internet. Not sure how to do this in D-Link as I don't use that brand but the manual will probably tell you. If not then tech support should be able to set you straight in just a few minutes.
