Hi,
If you're machine was prebuilt, go to the manufacturer's site and look up drivers for your model number. Those would be the more appropriate.
If your system was custom or self built, you can find the name of the network adapter in Device Manager or by running msinfo32 from the start/search line and looking under components.
Sorry for the delayed response, been away on holiday.
