Vista - drivers for Belkin 54g?

I just got my new Vista x64 gaming PC a few days ago.
Have just made backups and installed an antivirus and most of the apps I need.
I just need to set up my internet connection to update everything and then I'm good to go.
The problem is that my Belkin 54g router doesn't seem to work on Vista x64.
When I plug the cable into my 32 bit XP PC, a LED goes on.
On my Vista x64, nothing happens at all.
From what I heard I need drivers to make it work, but I have no idea which drivers, or where to find them (I've fruitlessly googled around for 2 days now)
I even called Belkin tech support but they didn't give me any useful information at all (they said I should get the drivers from Microsoft or the manufacturer of my PC)

If anyone could link me to a driver to make this work, that'd be great!

Specs:
Router: Belkin 54g (ADSL Modem With Wireless G Router)
model nr: F5D7632-4 ver. 6000df
OS: Windows Vista Home Premium x64
Motherboard: MSI P7N Zilent Triple SLI nForce 750I SLI S775 ATX DDR2 Zalman (a network card should be built into this, don't know if you need this info to solve my problem or not)

You shouldn't need any drivers to make the router work (in that there are usually no drivers required for a router). You may need drivers for the Realtek network port in your Vista x64 PC though.

Any idea on where to get those, since googling around didn't make me much wiser (I can only find drivers for audio related Realtek products)

I also installed drivers for my motherboard, but still no luck, the LED will not turn on

Also, I edited my first post with some additional info on my router:
It's a Belkin router, model nr: F5D7632-4 ver. 6000df
