I have an Actiontec DSL modem with built-in router. The modem has four 10/100 Base-T ethernet ports. Seeing as the modem router is not a switch, is there any value in using more than one of the modem's ethernet ports? Right now, I have one ethernet cable running from my modem to a 5-port gigabit switch. Three computers and my network storage drive are then connected to the switch. Is this the best way? Any suggestions? Thanks!
