Ethernet switching to 100mbps from 1000mbps when playing games

[Spooky88]

So for like a month now my ethernet has been acting crazy by switching back to 100mbps from a gigabit connection. It usually takes around 15 minutes of playing something for it to happen. If I'm downloading or doing anything else internet related it works perfectly fine. I do have a cat6 cable and a motherboard that supports gigabit speeds so the problem is most likely not with those. Options like energy efficient ethernet and green ethernet are all turned off(turning them on makes it even worse). If I try to force gigabit speeds it works perfectly fine until I try playing online games which makes my internet drop connection every few seconds.

if its just games and your speed test and other task are running at gigabit speed, it might be a ping related issue
