slow upload speed while live streaming

[BadWifiGuy]

So i used to stream to twitch a while ago perfectly fine with my speeds being perfectly normal with my bittate not moving around too much and staying where i set it.

fast forward to a couple of months later and i dont know what is causing the problem or what it is. My task manager is showing my ethernet going up and down a whole lot. I can play games perfectly fine and my downloads are fine too. My upload speeds always appear to be fine but whenever i start going live my streams start to look all blurry and get in the 1000kbs and under and it never used to do this at all

 

Please help me solve this so i can get back into streaming.

Thanks
