So a few days ago ive been having really but really bad internet, but it happens ONLY when my brother gets on his laptop. We share a 10mb internet and when he is not on, i get 70 ping to servers, when he is on, it can go up to 1000 or more ping. When he is off, youtube videos have 9000kb/s connection speed, and when he is on, just 100kb/s... I think he gave himself all the power of the internet (bandwith). How can i know if he did? or what the hell is going on with my internet... Please help
