Is my D-Link router losing packets or is my internet being stolen?

Question

WiFi

Hello, my router started to lose packets, and every 10-20 seconds it slows down. Here is a video of how it appears.
First of all, I checked if the network conflicts with other routers, it turned out that it didn’t.

Second, I called my ISP and asked if there were any errors in their network. And they didn’t do anything to my request to restart the server (or they did, but nothing changed).
The third thing I did was update the router software to the latest version (I did a full reset and updated it with a file through the computer via wire), it only helped for a week.
Fourthly, I decided to read what the logs write, but alas, I got stuck here: here is a link to txt log files made on different days
As a result, I want to find out who is to blame for the provider or the router. Otherwise, someone connected to my internet (not wifi) and steals some of the traffic, which leads to my problems.
Can anyone help me understand what is happening and why?
Thank you for reading my problem to the end.)

Hahaha, arech is so raw that there are a million bugs, lags and crashes. It's most likely the game itself. Maybe it's the computer. And last but not least, the internet.
But if we talk about the router, then it can lose packets either due to overheating (it must be rebooted periodically), or due to Wi-Fi. Wi-Fi, in turn, can lose packets due to interference (because your graph does not explain anything), due to people passing by, or due to other users (check the user list on the router).
From experience I can say that yes, routers lose about 1 packet per second. Most likely, this is due to the poor build quality and software. Still, these are home routers, business does not use them.
