I have reloaded Windows  Xp on a used Dell D630 laptop I had purchased reciently.  Now Windows (Device Manager) needs a driver(s) for the Ethernet Controller and Network Controller.  Have loaded from Dell's Website Network Application R151334.EXE & Network Diagnostics Utility R151336.EXE.  Still does not recongize the driver for the network card.  How can I findout with network card is in the laptop ?
