NightHawk AC1900 Model R7000 Speed test QOS

Using windows 10 firmware is always up to date 

So i been getting Internet spikes on my gaming console i will oftenly lag out of game but Internet does not go off it comes back on in a couple of Seconds. Been having this issue since 7/21/2017 i was doing a wager match cause i play competitive Call of Duty and i got booted offline twice maybe and more than that so idk if that messed it up or not. 

I think maybe because of my QOS it is dropping me out cause speeds maybe wrong my plan is 200 download and 12 upload i did the QOS speed test and i got 230+ download and 12 upload is this accurate if i do a speed test on any other web site i don't get even close to those speeds maybe the QOS speed test is wrong and is messing up everything please Let me know i also live stream but i got upload for stream at 2200 so its more than enough nothing is wrong there its been happening ever since i got booted offline DOS? or DDOS idk just need help ASAP. I did reset both modem and Router multiple times hope this is good enought info.
