[TriLUG] NAT / home network connectivity problem

[Jason Tower]

some 3Com cards have trouble with detecting the cable or negotiating the link 
speed and/or duplex (one of my 3com NICs ran into this at the NCSU 
installfest).  not sure if it's a linux kernel module issue or a hardware 
(but i'm inclined to say hardware).  supposedly there exists a DOS utility 
that can be used to change the bios setting on the nic itself, that might 
bring you some relief.  i'm sure cnet.com or mr. google can help you find the 
utility.
