Do you need a hub in a small home network?

Question

Iron

There is a home network based on the Zyxel Keenetic Giga router ; NAS Synology Disk Station DS107+ ; personal computer (connected via Ethernet); IP-TV set-top boxes (connected via Ethernet) and two Wi-Fi -n clients (HTC Sensation, Aurora II). In the future, expansion is planned: another computer (wire), set-top box (wire), TV (either via the network or via a media player).
QUESTION: Does it make sense at this stage (before expanding the network) to install a network hub such as Zyxel GS-105B between the router, NAS and computer, will there be an increase in performance? My thoughts are that the router will "relax" a bit - the main packets will go through the hub. Plus, whether the presence of a hub can increase the security of the network.
But, the main issue is to increase the speed. Offload the router to a wired network so that it works more / faster with Wi-Fi. Will there be a speed boost?
Thank you.
PS: Everything that is wired goes to GigabitEthernet.

Answer 1

Nothing will most likely change. The router has separate chips for the built-in switch and routing, so it works no worse than a separate switch.
And yes. Hubs have long since died, now there are only switches.

Answer 2

An unmanaged switch is a switch in which there is one bus connecting the ports, a piece of iron, so to speak, with the ports; the speed (protocols, collisions, etc.) of routing will depend on the routers (oddly enough), the number of hops and the structure of the network, and not on the switch. Therefore, the speed will not change.

Answer 3

Plus, whether the presence of a hub can increase the security of the network.
Why would she rise from this?
I don’t see the point in acquiring another piece of iron that will blink light bulbs.
An example of a rake that you can get if you plug an iptv prefix into it, because in this case the multicast will fly to all 4 ports, which is not good

Answer 4

According to my feelings, the main problems arise due to encryptions (vpn to the provider and AES for WiFi), and the load on them just will not decrease from the router, especially broadcast and layer 2. And the problem, as I understand it, is the lack of ports?
PS The owner of Keenetic lite himself, and when chasing packets within the network, even via WiFi, the load on the processor is quite small, but it doesn’t give more than 5 + mb / s outside.
