ZenFire,
Atheros is the chipset around which many D-Link Wireless products (including yours) are designed. Question - does the Atheros driver work?
I believe you have a "D-Link AirPlus DWL-G520" - there are 2 revisions of that product so you need to identify the correct rev of the hardware you own.

Its not recommended to install hardware driver updates from the windows
update website. It takes microsoft a while to get permission to release the
driver updates through their site and there is usually a better/newer driver
released on the manufacturers website. You can browse for your specific
model on this website:

I'm thinking those Atheros chipset drivers are from a Vista update. You may want to uninstall that update.
Go to D-Link's site, identify your model and download the drivers for your OS.
