What is the quality of Wi-Fi at home?

Question

WiFi

I put a wi-fi router in the corridor of the apartment (brick walls), I don’t want to pull the wire to the PC and TV, after all, the 21st century is in the yard.
The question arises, what will be the quality of the Internet in this situation, will there be any loss that may affect online games?
And take the cheapest wi-fi adapter, or do not regret it and take the norms? Internet optics 100 MB. Thank you for your attention.

Answer 1

Let's say that my laptop downloads torrents via WiFi in the hall 3 meters from the router at a speed of 5 MB (Internet speed is 50 Mbps). The same laptop, when moving to the kitchen, continues to download at a speed of 2 MB - a distance of 10 meters, 2 white walls of 16 cm, strictly perpendicular.
In addition, due to the 21st century, a HUGE amount of interference from the same routers from neighbors from all sides appears in a residential building.
Judging by the layout, there are no special problems to stretch the cable along the wall, you are guaranteed to get your 100 Mbps on your computer.

Answer 2

No router name.
No indication of the type of walls (bearing, with iron beams and plaster - different things)
No information about what the neighbors have, and the neighbors' routers can cause serious interference.
No indication of the frequency at which you are going to raise wifi.
In your case, if you need it cheaper, the cheapest thing will be to call the master from the provider so that he cuts and crimps the cable for you, and stretches it under the wall.
Moreover, if toys - then wifi always gives additional delays.
