Hi I'm using a Omen 15 Laptop and use a wifi with 2 other roommates. When I'm just watching videos there is no problem and it is high speed. However, when I start playing games, the speed goes unstable. I get 20 ping at times, but also spike up to 2000 ping. I tried a lot of things and my friends say that they have no fluctuation with the internet and it is only me that is experiencing it. The only thing I did to my laptop is that I added another 8GB RAM to it.
