Question

I bought my computer (Dell latitude D410) in Europe online. I was unfortunately not sent a drivers CD. Am currently in Africa and recently reinstalled my operating system. I managed to download drivers for Audio, graphics and intel PRO wireless card. These have worked successfully. However the ethernet drivers (which i thought were named broadcom on the dell support website) have not worked. My ethernet card is hence still inactive. Where can i get drivers that can solve this?
