Hi! Here's a detailed description of what's going on, any assistance is greatly appriciated!
I started observing this issue about a month ago. I tried to fix it by changing my location, restarting my router and PC and looking into other solutions that turned nothing up.
I figured it was just the particular game I was downloading, but when I then started downloading other games the other day, I had the exact same problem with those. The speed goes up, some times to my maximum (25/30mb/s) then just drops to 0 and starts over, often jumping or staying around half my normal speeds before it drops and restarts again.
Ontop of this, I've noticed Twitch is starting to do the same thing. I monitored my Ethernet load when I was watching, having tried different streams and different browsers, that my Ethernet load was doing pretty much the same thing of going up then down to 0 which caused buffering.
What's going on here? I have no issues with ping in any games at all. I never disconnect. I never stutter or lag in games. Voice programs like Discord work fine. Everything else works fine. The Blizzard app downloads normally. Origin downloads normally. I can watch stream on my Ipad without buffering.
I have no anti-virus.
I use no VPN.
Only Steam and Twitch are having issues, all other programs are working without issues.
I did a speed test, which showed a perfect load on my line, nothing broken or lost.
Since the Ipad doesnt buffer, I must assume the problem is in my PC.
So, what the hell is going on? Are there ports that need forwarding? Is there some conflict that I'm missing?
Edit: Ive noticed something even weirder. Twitch stops buffering on my PC if I have the stream I'm watching also open on my ipad.
