Question about ethernet driver

Hello, for some reason my XP windows desktop has an Ethernet port (just the 1), and when i plug in my broadband Hub, the computer doesn't recognize the Ethernet cable , cos i don't have a driver installed. Can someone tell me a way i can install it. (preferably a link to a site where i can download it straight from)
