The NIC is most likely the Broadcom found here: [URL] Many of the other devices listed are the wireless variety, which I assume you are not asking about. For what it's worth, I am typing this on an Inspiron 1100. It has the Broadcom built in network interface.....
I can't determine it from the BIOS, from within device manager and the Dell download list has 10 -12 possiblities.   So please, is there a way that I can determine which NIC this laptop has.  Fwiw, I am not using it to type this msg. Thanks, Scott
