I'll start out by saying every other device in the house works as it should whether it be connected wireless or directly. My desktop consistently tests at 40-50mbps on several speedtest website whether im connected wireless or directly, so it would be it's definitely my desktop being faulty?

However using the speed test provided by Rivet Networks, it shows 400+mbps?
Screenshot for comparison: https://gyazo.com/3de67944db307aa121813e5041057354

Screenshot of ethernet status: https://gyazo.com/ff78262098a7573331f54018039e8173

The properties page for the drivers of both the wireless and ethernet "adapters" are updated and show "This device is working properly."

When downloading something, like a large file, the speed consistently stays at around 40-50mbps so I'm definitely using 40-50mbps rather than the 400mbps listed by the above screenshot. I've ran full scans ensuring there's no malware or threats to the device.

Honestly a bit lost, so any advice would help.

Open Command prompt and type ipconfig/release then hit Enter and then type ipconfig/renew hit Enter.
Do you get any errors? Test speed again.

If that does not do the trick then try these
Open Command prompt as Admin.
Type the following commands to reset your network settings:

Type netsh int ip reset hit Enter
Type ipconfig /flushdns hit Enter
Type netsh winsock reset hit Enter
Restart your computer and see if the speed improves.

Hi I tried the first solution and not really sure what to look for to be honest but this is what came up: https://gyazo.com/993b3876888a15ac938bb768c2bb987d

Tested the speed anyway and was still the same 40-50mbps.
I then followed your next advice, restarted and tested but again still the same.

The Rivet speedtest.exe that I mentioned earlier I still showing 400mbps for what it's worth.

You'll want to isolate the PC to being either hardware or OS related. I recommend creating a bootable USB flashdrive of Ubuntu (or any Linux flavor), boot from it, then re-run your speedtests again. If all is good, then you know your hardware is functioning fine, but something in your Windows OS is corrupted or you have some utility throttling the connection.

Try uninstall your network adapters from the Device manager and reboot
Either, allow Windows to install drivers or get the drivers from the manufacturer of your PC or motherboard manufacturer or network chip manufacturer.

You could get the drivers before uninstall your network adapters.

If I uninstall the drivers and restart computer, will windows install their own generic drivers so I can still access the internet?

I'll have to start reading into how to do that, would a clean wipe of the PC determine whether or not is OS related or do you think the same problem could crop up again as if it's something that actually installed with the PC by default?

before you start re-installing windows try the Ubuntu live cd dragon spoke of. here is a link with tutorials.

https://tutorials.ubuntu.com/tutorial/try-ubuntu-before-you-install#0

will basically allow the full system to work with linux running from a cd or usb drive. this will let you test the connection speed outside of windows. if it gets full speed, then you know you're windows is jacked up somewhere. if it still runs slow, then you know it is the hardware causing the issue and can start there.

will save a ton of time chasing the wrong issues if you know whether it is OS or hardware related.

Windows should install generic drivers.
You could uninstall one network adapter at the time or download drivers before just in case.

I uninstalled the drivers but it just reinstalls the exact same ones when I restart. However, weirdly, within literally the first 5 minutes of the restarts after uninstalled drivers, my speed tests start booming up to 280mbps, then after those 5 minutes back to normal, I thought the hardware for the wifi and ethernet cards were just broken, but now I just don't know.

You may want to use different drivers.

I also found that Windows 10 Auto-Tuning could cap network speed. Try to changing and see if it helps.
Check the status of Window Auto-Tuning by running CMD as admin.
Type netsh interface tcp show global hit Enter
See the value for Receive Window Auto-Tuning Level if is set to Enabled you could disable it or vice-versa
Type netsh int tcp set global autotuninglevel=disabled hit Enter to disable it.
Type netsh int tcp set global autotuninglevel=normal hit Enter to set it to default.

The auto=tuning was set to normal so I disabled it but to no avail. I'm going to look into trying some other drivers, then tomorrow I'll try using a different OS, then I guess buying new wifi and ethernet cards lol.
