I have 2 Realtek 10/100 NIC's model's RTL8139A and RTL8139C and a linksys Network Everywhere Model NC100 and am looking for the best compatability with XP Pro in a DSL sharing environment Networking 3 computers through a router and perhaps a 10/100 switch as well. 1 computer will act as a game server. Any opinions on these NIC's would be appreciated as well as driver recommendations.
