Sometimes my internet speed on my router just crashes randomly or completely slows down to the point i get unplayable ping in video games . so I thought I could use my mobile hotspot on my phone. When my computer is connected to my hotspot it gets 20+Mbps Down and 15+ Mbps Up and about 40 ping( used http://www.speedtest.net/). So why is it when i actually play a game i get 100+ ping even though I have these speeds
