I was having terrible problems with the built-in 10/100's in my Dell
620's, but it turned out to be an autonegociation problem caused by a
netgear 10/100 hub. A few days ago, I swapped the hubs out for 5-port
linksys workgroup switches and now get 90Mbs sustained full-duplex. I
suspect that in most cases, the NIC's are not the problem -- its the
hubs/switches and/or network configuration. There's probably very little
difference between the intel and 3com cards. I do highly recommend the
linksys 5-port switches for small networks.
