High Ping due to MacBook?

Question

Ping

About a couple of months ago, I began to ping the Internet hard on all devices, mobile, stationary computer (it became impossible to play cs). I thought it was because of the ISP.
But .. a couple of days ago I found out, while playing CS, that when I turned it off from Wi-Fi, a miracle happened, the ping immediately became normal. I checked the test several times, I realized that because of the poppy.

The question is, why could this be?
I think that only iCloud can pull, but I only have 1.5Gb of files there. So I don't know. Please advise what to do)

Answer 1

The only way a poppy can influence is to download something from the network (or give it away), as a result of which a weak router simply has a large load on the percentage and the speed on other devices drops.
Install iStat Menus, it has the ability to track network activity from a computer and you can understand at that moment there is some kind of activity or not from a macbook. He has no further influence.
