To increase the speed of the network a friend suggested that I subnet the computer. Is this possible, if so, where do I begin?
Subnetting will reduce the amount of broadcast traffic. If you decide to subnet you will need a router. I would suggest replacing the hubs with switches. Why? Because hubs don't segment traffic; therefore they cannot offer the speed of a switch. If you cannot replace all the hubs at once move your powerusers, servers, and domain controllers to switched ports. A final reason to replace those hubs is because they allow anyone connected to its ports to sniff traffic on that segment of the network. That's an increased security risk.
