Intro: I live in Brazil, here I have a 2MB internet connection. When someone else is watching a video on Youtube or Netflix, I can't play anything, the ping oscillates so much. I can't play any online game, eg: League of Legends, Counter Strike or even slither.io.
Question: Is there any way to configure my Linksys E900 QOS to solve this problem, I mean, by prioritizing games without blocking the video that is playing.

Latency problems on home Internet connections usually aren't due to a lack of priority, they're usually due to crappy modems/routers/gateways/APs that, in a misguided effort to never drop a packet, allow their buffer queues to become bloated and stay bloated, which does a double-whammy of adding latency while at the same time breaking TCP's congestion control algorithms.
The solution is to run a router that does Smart Queueing, which is an advanced form of Active Queue Management. The two most well-respected Smart Queuing algorithms are CoDel and PIE. Routers that implement these won't let their buffer queues get bloated. They will do Explicit Congestion Notification on packets as congestion becomes a problem, and they will be smart about dropping packets if ECN isn't enough. This allows TCP Congestion Control to work.
Luckily, there is aftermarket firmware for your E900, such as DD-WRT and OpenWrt, that support CoDel.
For more information, see bufferbloat.net.

1You can prioritize outgoing traffic, but not really do much about incoming traffic. The bandwidth has already been used by the time you see incoming traffic. – Ron Maupin – 2016-05-15T18:02:08.280
@RonMaupin So, there's nothing that I can do about it? – Wellington Zanelli – 2016-05-15T18:04:59.617
Ask the other users to stop while you play a game, make a schedule when each user has a time to use the internet for high bandwidth stuff like movies and youtube. – Moab – 2016-05-15T18:06:46.627
