Ok so I have this really annoying problem that whenever my brother uploads a video to youtube, I get like 600-800 ms pings on the games I play. I usually get like 60-80 ms when he isn't, it's 10 times as bad.

I've tried setting my priority higher than him in the network settings, that did nothing to help. I tried changing the priority of youtube, fixed nothing. He won't let me install netlimiter either -_-
