My Dell Dimension 2400's Broadcom 440x 10/100 Integrated Controller Ethernet card Only works at 10MB Half Duplex. I bought it in December, 2003, but I never realized it only works on 10MB because when I got the computer we set it up to be wireless, and now we finally got it wired and it doesn't work at 100MB, and I am disappointed.

Actually, about 2 years ago after i hated wireless (phone interfered with it) we tryed setting up a wired connection. It worked on all the computers in my home except for mine, because it wasn't set to 10MB (which i didn't know about..)
