When I boot a game up like WoW or just have a loading screen in general / go to a different area it will lag my other programs out, youtube will freeze, twitch will freeze and get an error, spotify will pause saying (cannot play this song at the moment) and discord will sometimes lag out like robotic voices. Same thing happens when I do a speed test. This has only been happening the past 2-3 weeks. I've contacted my ISP about it also but they said my speeds are fine, they trouble shooted the lines also.
It's not only WoW that does it, it seems to be multiple games.
