Which one on that page?...there's only one wired lan listed and it's for an Intel Pro/100VE and Pro/1000MT onboard Ethernet adapter. You must download the driver that matches your hardware. If your hardware isn't this, then download the driver for the hardware that it does have.
What didn't work? give some details please.
