QoS stands for Quality of Service. It allows you to dedicate and split traffic and bandwidth for certain groups of packets. Eg. Prioritizing gaming over streaming but prioritizing chat data the least.
 
Run a constant ping to 8.8.8.8 and see if you see corresponding high latency or packet loss when the problem happens. You can ping the game servers also if you see nothing on 8.8.8.8 but that would mean a issue someplace in the internet going to the game servers rather than something on your connection.

You can also let a constant ping to your router run but I do not suspect you will see much.....I will assume you are not running on wireless because that can causes all kinds of issues.
