I hate to differ on this m8 but cable modem will not work with a hub ( at least this is what i have found )
What you need to do is first decide which is going to be your main pc and put two network cards in it one for the cable modem and one to conect to other pc
then set up the pc with the cable modem on its own first , then connect to other pc via network card
and there you go just set up file sharing etc with your local network
Both pc's have Windows 98. I'm thinking about upgrading one to Windows XP. Can they be different when networking? yes they can be different op systems
