This has been happening ever since my family found out about YouTube, years ago. Whenever anyone watches a video on their phone, iPad, computer, etc, games that I play such as DotA 2 and Counter-Strike GO experience non-ping related lag. As in, when I play there is definitely some sort of lag going on where I teleport back and forth and it seems like the game is refreshing every .3 seconds or something. So everything looks like it's lagging, but when I check the ping in-game it turns out exactly as it would when I'm not lagging. I've tried fixing the problem many times before, and the only solution I have is turning off YouTube on every device. I want my family to be able to watch whatever they want, but I'd like to find a way they can do that without this lag happening. I've even tried using the QoS feature on our Netgear router, but that doesn't do anything. Thanks for reading.
