How can I strengthen the Wi-Fi signal in a 4-storey private house?

Question

WiFi

Good afternoon!
There is this:

House of 4 floors, private. On the top floor it does not catch, and if it does catch sometimes, it is very, very bad. I would like to fix this issue somehow.

Answer 1

I would advise you to put AP on all floors, unscrew their power to the middle or minimum and make a single coverage area, twisting the signal, you lose a lot in channel quality while you are sitting on a weak Wi-Fi on the last floor, those who even sit on the first floor next to the point , feel a deterioration in the quality of communication, due to the principle of operation of Wi-Fi. You can fence antennas, install amplifiers, but best practice is a lot of low-power points, the signal of which should not pass through the overlap and a single zone for them.
