Hello all,
This is my first post so please be gentle!
To start here are my PC specs;
ROG Crosshair VIII Formula MOBO
AMD Ryzen 9 3950x CPU
G.Skill 64GB DDR4 3600 RAM
Gigabyte Aorus NVMe gen4 PCIe M.2 1TB SSD
ASUS ROG Strix GeForce RTX 2080 Ti OC Edition 11GB GDDR6
WD 1TB HDD
Windows 10 Home 64bit
Today I was downloading a piece of software to my main PC and my laptop and suddenly realised that my laptop was downloading it at about 41Mbps but my PC was downloading at around 5-6Mbps (task manager). I thought this was odd so downloaded them again and had the exact same results. I then tried from a another PC on my network and it again downloaded at around 40Mbps but my high end PC was stuck at 5-6Mbps.
I began investigating and thought it was maybe a bad ethernet cable, so tried a new one and was still the same. I then plugged my laptop into the exact same ethernet cable and got fast speeds so I ruled out any networking hardware straight away (my network is all unifi equipment). My PC has a ASUS mobo which has a 1g ethernet adapter, a 5g ethernet adapter and wi-fi 6 adapter. I have tried the same scenario on all three networking adapters and still get the same slow speeds even after updating all drivers and checking they are all set to forced gig duplexing.
I then tried all of the following steps with no improvement;
Image 1: Slow download speed problem PC
Image 2: C drive speeds on problem PC
Image 3: Much faster speeds same ethernet cable on Laptop
[Edit]
Image 4: This morning I tried a file transfer from my internal server to my M.2 drive and have decent speeds (816Mbps) so not a hardware or driver limitation surly?
Thanks in advanced

I then tried all of the following steps with no improvement;
- I tried to download the same file via Microsoft edge instead of chrome with no difference.
- I have tried moving my downloads folder from my M.2 drive to the HDD drive in case of a software bottleneck there but again the same slow speeds.
- Updated the BIOS, all chipsets and windows - no difference
- I do not have ROG GameFirst installed
- I disabled all antivirus programs and closed all unnecessary background programs
- Ran a speed test using speedtest.net and get about 37Mbps download!
- Tried downloading files from another site and it got to about 17Mbps sometimes but this is still far from the 40Mbps my other devices are getting
- I have checked that no power saving options are turned on for the ethernet adapters or my system
- I have uninstalled tunnel bear VPN in case this was clashing somehow
