We still need to know what revision card this is, A or B. This will determine what method to use to get the card up. One is a Marvell chipset, the other is Atheros.
If you don't know where to look, refer to the previous link that I gave to the D-Link webpage and note the revision number for your card.
I assume that you know your security settings (WEP or WPA keys) and your essid to the router?
If it is a revision B, the Atheros chipset model, then look at
this previous post about the 11th post down, which gives a good description of what to do. It is the first post from dleon.
