D-link Adapter-Installation

Iam using Win XP (no upgrades)and trying to install a D-link DWL- G510 Desktop Adapter. After loading the software an installing card the lights on the board alternately blink and on the bottom line of the desktop I have A white “D” with a moving red line in it. The text box over the”D” states “D-Link AirPlus DWL-G510 Wireless PCI Adapter(rev. B) Not Connected”. After card installation & turning on computer I do not get an indication that new hardware has been recognized.
I do not know what to do next
