I agree with Dave,
With out some detailed and precise information about your set up, it's difficult to help you get your system going.
Please check to see if you have anyone with some or experienced knowledge like a neighbor, friend, or computer service company that you can talk to and have them come to your house and help you get everything going and running for you. I don't think there is anything wrong with any of the the devices here, it's just seems to be getting it setup correctly. Cables and devices. And don't let them tell you that DLink makes bad devices either. They need to prove to you that any one of your devices is bad before you have to try something different.
Can we ask you what part of the world you live in?
Theres got to be some places or people around you that can come to your house and help you.
