I've been playing Dota 2 for 3 years now but never have I encountered this problem not until this year. I have 90 ping when playing Dota 2 but when someone starts streaming videos in my network the ping becomes 500-600. The game is literally unplayable with 7 seconds delay. This problem started at the start of the year. I have two broadband subscription. One from home and one from apartment where I am staying for school. The same problem occurs in my other network. Can someone tell me what the hell is happening?
