How to organize the distribution of wi-fi in the apartment?

Question

WiFi

Good day! Friends, please tell me how to organize the Internet and the distribution of wifi at home. The approximate plan in the figure is a 4-port router at the entrance, which distributes to 2 TVs and 2 wifi routers.
1. How to organize a wifi network - put 1 device that could distribute a strong signal throughout the apartment (then what device?) Or 2 wifi routers (but then how to ensure that when moving from room to room, a device connected to wifi connected to a stronger access point signal or both wifi were peer-to-peer)
2. Is it worth taking a gigabit router at the entrance or 100 Mb?

Answer 1

1. It is still not clear whether the increased power of the wafer is harmful. pushing away the worst. it means it is better to use a repeater than to constantly cut in what irradiates the device between the legs!
2. if something like HDTV and more abruptly is planned in the hut, then definitely gigabit ports . to stick network storage.
3. it is desirable to support ac over the air.
Note: You can hang two points. tie on the cord and file a seamless roaming
although it is not entirely clear why you do not put one point in the center of your hut. one point easily breaks through 2 walls.

Answer 2

I would first try to put a WiFi router at the entrance, and limit it. If it does not pull - then I thought further.
From experience - 2 reinforced concrete walls of 18 cm each break through without problems. 2 brick walls, one in half a brick (12 cm), the second - 2 bricks (50 cm) - is also a weak barrier.
Is there a desktop with a computer in the apartment? Do you only run wires to TVs?
