styler,
There is only one third-party wireless driver that I am aware of which supports 802.11g PC cards and it is OrangeWare:

Unfortunately, your card is not in the supported list. OrangeWare's driver supports cards that use the Atheros chipset, and apparently your card uses either the Prism or ACX 111. As is often the case, D-Link and others will often switch chipsets yet keep the same model number of the card and give it a revision number.
I am unfamiliar with Windows, but you should be able to find the specs on your wireless card when inserted in the card slot. But unless it has a Ralink or Broadcom (Apple) or Atheros chipset, I don't see how it will work.
