One wifi device kills the connection for all the others.

So my sister got a Samsung Galaxy S7 Edge in January, there were not problems until two days ago when i noticed that the connection started to have problems.
While playing online games my ping would immediately go up to 300/400 m/s.
I then realized that this issue was when my sister was at home so at the beginning i asked her if she was uploading or downloading something, but she weren't.
I've tried to see if all the applications in background weren't running uploads, and they weren't.
I've also called my internet provider and they told me that the connection has no issues, so they can't resolve my problem..
I've also tried myself to change some settings of the router but nothing changed, so now i ask you guys if someone have had the same problem and if you solved it, how you did that because by looking on the internet, even in old posts on this forum i couldn't find anything that helped me.
 
By the way guys, if anyone had the same problem i've finally solved it. My sister phone had an application that was constantly uploading datas, it was a Google application called photo. I resolved it by simply stopping the app!
