I have 2 computers at home -- a pentium III (A) and a core 2 duo (B). I want to connect the 2. My B computer has its LAN card used for broadband. How do I do it? I'm thinking of purchasing an ethernet card for my A Computer and a rj45 cable to connect. Is this even possible? I want to connect my B computer from USB while my A computer through the ethernet card. I really have no idea about this so, I hope someone could help. My A computer has 1.0USB while my B computer has 2.0USB that's why I wanted only my B computer to be connected through USB while my A computer connected through an adapter. What are the things I need to buy?
