How to connect all devices in the apartment to WIFI?

Question

Computer networks

Good day.
Available:
3-room apartment
1 wifi router
2 laptops
Description of the problem:
A hospital
appeared And there was a need to connect the Internet to a room where it is not possible to conduct a lan-network, only via Wi-Fi
Question:
What is better, to conduct a separate lan network to the hospital, or in this In the case of a router for distributing Wi-Fi for laptops, it will distribute a lower speed. Or put 2-3 repeaters in the apartment so that the Wi-Fi connection is excellent throughout the apartment, but what is the possibility that the speed of the Internet connection will sag?
If repeaters, then what. Or better describe your answer what is better to do. And how to proceed.

Answer 1

in a room where there is no possibility to conduct a lan-network

Yes, you decide whether it is possible or not)
As for me, then buy a Wi-Fi adapter for your computer and do not bother anyone with such questions. Or do you have 10 Gb / s Internet, that your Wi-Fi will be a bottleneck?

Answer 2

Your router isn't exclusively wireless, is it?
Pull the Ethernet cable from it to some place that will be as close as possible to your desktop computer, and where you can drag the cable. Put a second router there with a different SSID and connect only your desktop computer to it.
In this case, two of your laptops will continue to fight for one WiFi channel, as it used to be, and the second will be in the exclusive use of a stationary PC.

Answer 3

If the Internet from the provider is not very fast up to 20 Mb / s and only Internet access is pursued, then it is enough to plug a wireless network card into a stationary computer and that's it.
