Will these wires and hub be suitable for building a network?

Question

Computer networks

Hello!
Now there is a router with an iota (usb modem is plugged into the router) and distributes wifi.
But now it is necessary to connect new computers. The signal is weak through the walls, so I'll pull the wires. Hence a few questions:
1) If I buy a
wire
switch
will I be able to make a LAN?
2) It turns out 1 patch cord will lead from the switch to the router with iota. Can it be configured so that the Internet from the iota can be given to some computers connected to the switch?
3) How to make Wi-Fi users seem to be in the 1st subnet with "wired" ones? Those. so that you can use shared folders, printers, and generally put a web server that would be visible to everyone.

Thanks in advance for your replies

Answer 1

1. Yes, you can.
By cable - in the description it is written that "category 4", and on the box 5e. This is strange and suspicious. Category 5 is required.
Switch - I would take with support for 1 Gb / s.
2. 3. You can. You don't need to do anything special for this - everything should work as you want anyway.

Answer 2

Cable - copper-plated aluminum. If you need more than half a year and / or a fixed mount (installation) is not implied, it is better to abandon it in favor of copper. Omednenka has the property of oxidation at the boundaries with the external environment (sockets, connectors) and has increased brittleness on bends. Also pay attention to its category (although it may be lying on the site).
At the expense of the switch - add a little bit and buy with gigabit ports

Answer 3

Hire a sysadmin, my advice to you.
But in general, yes, it's all real with your selection of equipment

Answer 4

Valentin said everything correctly, there is not even anything to add.
It is better to take the switch from at least some well-known brand. Netis - it's generally unknown what, and what artifacts it will give on the network - the question is dark. D-link, TP-link - much more predictable. For example, this one: https://www.citilink.ru/catalog/computers_and_note...
