Wireless network Problem

I am having a problem connecting to my wireless network now that I have
upgraded to Vista home premium. I downloaded the drivers from my D-Link
DWL-G510 PCI Wireless card, and windows recognizes it, however it will not
allow me to connect to my existing wireless network. This is the network I
always connected to with XP but now it says it is not compatible with router.
I checked the driver and it says it needs an update, but there is none
available on D-Links site.

Also, this was a PC I built with an Intel Motherboard, it is pretty new, it
uses a 533 Bus with a 2.53 GHZ chip plus 1GB of 333 Ram. However, the
motherboard needs a soundmax program and others to work propertly, and when I
try to download those Vista says it is not compatible with the operating
system. I know this isn't the right forum for this topic but I figured I'd
lump them together.
