What computer or laptop is it?
It shouldn't matter I think. Just download the highest numer (9) and use it.
If doesn't help, tell me make and model. I will tell you correct one.
Edit: Nevermind. I see info. Looking now.
Give this a shot: It's nForce 430. Install by using the device manager only for network adapter. Right click network adapter. Update driver software. Browse. Let me pick. Have disk. Browse. Find the .inf in the extracted folder for lan or ethernet and double click it. Hit ok. Let it install. http://www.nvidia.com/object/nforce_...sta_15.01.html
