I have a 10/100 Linksys router connected to a 10/100 network hub and a 10/100 network switch. My computers are connected to the hub and switch.
I need more speed on my network, so I am about to replace the switch and hub with a single 16 port 10/100/1000 switch and add 1GB network cards to my PCs.
My questions are whether I have to also replace the router and if the Cat5 cable will restrict my network performance. Do I need a 1GB router and Cat6 for all of this to work?
