I currently have a DSL modem that connects to a Netgear 16 port Gigabyte unmanaged switch in room 1 of my house. I would like to add a few more computers to room 2. I do have the ability to run a network cable from one room to the other. The easiest way would be for me to run one cable from room 1 to room 2 and connect it to another switch. I'm not sure if this is the best method or not, at least regarding performance. I would like to hear other opinions for this type of setup. my ultimate goal is to isolate my network from a guest network. I realize I will probably have to replace the Netgear switch in order to do that.
