It seems with how simple network switches are that not too many people post videos on YouTube or guides on how to get the most of them. I'm aware that you plug many devices into them and it enables communication between them, but I would like to know if it's possible to run two ethernet cords side by side and double throughput.
Now before everyone slams me about just getting gigabit ports and being happy with the speed, let me give a few examples of what I'm looking for. I rent one room in a five bedroom house, so while my wifi reception is decent, it's not great for gaming and my equipment that needs an ethernet connection like my home surveillance dvr can't be located in the living room. I would like to hard-wire my gaming computer, my dvr, my tv, and my playstation to the internet but the router in the living room only has two available ports. Enter the network switch. The downside I see is that my four devices don't need to communicate with each other, rather each device is trying to communicate down one ethernet cord from the switch to the internet. Since the router in the living room has two empty ports, could I run two ethernet cords from router to switch so each cord only has two devices communicating down it instead of four?
TL:DR Imagine you have two rooms on opposite sides of the house with four networked computers in each room for a total of eight devices. Your mean landlord says you can only have two unsightly cords running through the halls. So instead of having one network switch and running four ethernet cables to the other room, you need a switch in each room with just one cable connecting the two rooms, creating a bottleneck. Is it possible to alleviate some of this bottle-necking by installing that second ethernet cable between the two switches, or would it still only communicate using the one?
