Which Wi-Fi router to take for a large house?

Question

network hardware

Hello dear forum users.
I have already read a lot of posts on the topic: "how to choose a wi-fi router for home"
but the point in solving the problem was not found.
The problem is the following:
We have a 3-storey building with block walls and reinforced concrete floors. There is 1 computer in the house, the Internet is organized by ADSL via the TP-Link TD-8817 modem (the speed declared by Rostelecom is 5 Mbps).
Recently, I bought myself a smartphone, and a tablet for my cohabitant. There was a question about wi-fi in the house.
What would you recommend to buy from routers so that you can use the Internet at least within the floor.
The price part is about 5 thousand rubles.
From everything that I read earlier, the choice fell:
1. on Apple Airport Extreme (a little high price)
2. ASUS RT-N16
3.ZyXEL Keenetic Giga II
Maybe you, dear owners, can advise something else, how to proceed in my question.

Answer 1

I solved a similar problem for my friends using TP-Link TL-WR1043ND.
The issue price is about $60. The device is located in the "geometric center" (of course, as far as it was possible) of a three-story building - on the second floor.
The signal everywhere, including on the balconies, is excellent. According to preliminary observations, it is the same on the porch, and in the underground garage, as well as on the site near the house (5-7 meters).
Of the "pluses" of this model - removable antennas (if necessary, you can "strengthen" some direction by replacing the drain antenna with a directional one).
Of the "minuses" - there is no 5 GHz band (although for me personally this is more of a "plus" - there is less than one microwave brain cooker in the house).
Well,from the manufacturer's website.

Answer 2

It is not necessary to buy one expensive router. I think it's better to buy some kind of cheap one + buy access points to it.

Answer 3

A set of three Ubiquiti UniFi will do. Have a good experience with them. A separate hardware controller is not needed, the functions of the controller can be performed by a program for Windows or Linux.

Answer 4

TP-Link TL-WR-941ND + 3x Tp-Link TL-ANT2408CL
e.g.

Answer 5

I have giga 2, through three brick walls (one of them is capital) it breaks through without loss (4 out of 4 sticks in macbook terminology)
before that it was long 2640 - it was under the same conditions 1-2 sticks
ps . since there are two devices - you can roughly estimate the radio permeability of the walls - distribute the Internet via Wi-Fi on one - walk around with the second device - see the signal level from the first one
, maybe not everything is so scary and in general any Wi-Fi router will master

Answer 6

With the indicated budget, ASUS is better not RT-N16, but RT-N56U or RT-N66U.
Most likely, when installed on the second floor, it will give a normal signal throughout the house.
