What equipment to choose for organizing a small local area network?

Question

network hardware

Hello everyone
Given 5-6 client PCs
The Internet enters the router and undresses via Wi-Fi
One PC acts as a server on which the database is connected to it via a local wireless network
Periodically there are complaints about quality and speed
What would be the ideal solution?
Buy a switch and distribute cables for everyone? Internet to start in the switch, or leave wireless? Requirements only stable fast connection to local server

Answer 1

Buy a Mikrotik first, like RB2011 .
It is a router with switch capabilities. 5 gigabit ports, 5 x 100Mbps.
And when other requirements appear (and they will appear), there will be no need to redo everything.
And yes, wired only.

Answer 2

Everything that can be made with copper, it is better to make with copper. Wi-fi is a capricious thing, depending on many factors that you cannot influence.
