XPS 8930, Upload Speed Dropping

Hi All,

I'm at a loss as to what I can do to fix this, last time it happened it was a simple fix by getting a new ethernet cable. However now that did not work.

My Specs are as follows

i7-9700

RTX 2060

16GB Ram

Killer E2400 Ethernet

Now for the problem - I have gigabit internet, and my download speeds would hover around 800-900Mbps, while my upload would sit around 500. Now they the upload is dropping to around 100...but the 100 isn't a "stable 100" as trying to stream at a 6000 Bitrate on twitch yields me dropping frames constantly, so I'm stuck on 3500. Now the last time this happened I bought a new cable and all was back to normal. I also got my brother to run a test on his PC, with his results being 800 down 400 up. So that rules out the network being the issue.

I've tried - IP release/renewal

                 Disabling Large Send Offload

                 Uninstalling Re-Installing Drivers

                 Full Network Reset

Is there anything I can do or is this an issue with the card itself? Like I said, its only my upload thats affected and it doesn't seem like its actually a full 100, when trying to upload/stream I can barely above a 3500 bitrate without it causing frame drops on OBS.
