Packet loss when playing from phone on wifi?

Question

WiFi

Internet 100 Mbps. There are no problems with the cable. There are no problems with ping and losses outside of games. Only if a low-demanding game with a network load of 1-5 kb / s problems occur - every 3-5 seconds the Internet seems to disappear.

The funniest thing is that if you start the download from the same phone (downloaded the game 3 GB), while the download is in progress, there are NO problems in the game, neither the ping increases nor there are no losses. I don't know how it works.

There are no other Wi-Fi points within a radius of 20 meters, Wi-Fi from the phone is at a distance of 20 centimeters, on the same level.

Answer 1

question from the series how to find a black cat in a dark room.
no one here knows how networking is implemented in the game. no one knows how the server part of the game is implemented. no one knows the workload of the selected WiFi channel. No one knows about radio interference in your premises. How was packet loss diagnosed? in this particular game? what does the game support say about your problem?
what does ping have to do with it and how can it be measured on the phone simultaneously with the game and what exactly is being pinged? By the way, by launching a ping over WiFi simultaneously with the game, you occupy the transmission medium and worsen the working conditions of the game.

Answer 2

Change phone, change router, find the reason.
