For some context I recently moved into a newly built apartment. Pre-installed in every unit is an Xfinity xFi Gateway with Cat 6 ethernet routed through the walls to various parts of the apartment. On my internet plan I selected the 800Mbps option, and over wifi speeds are pretty reliable. My issue begins when I plug my PC into the LAN port in the wall.
For the past few days my speeds have been all over the place. Today I ran 10 internet speed tests consecutively, and I've attached screenshots. It starts at around 800Mbps and immediately drops to 0.5Mbps the next test, and it has been doing this for the past few days (see Imgur album for the other trials). If I'm not mistaken, I should be getting consistent/near 800Mpbs speeds through ethernet every time, as I am the only person on the network. I've tried:
So this leads me to believe something is wrong with my PC, as not even the USB wifi adapter could fix my problems (the wifi works fine on my mobile devices and smart TV). I know my ethernet connection can supply around 800Mbps, but I'm not sure why it drastically drops to 300Mbps and sometimes even as low as 0.5Mbps as seen in the screenshots.
Here are my PC's specs if that helps:
Motherboard: MSI B350 Tomahawk
CPU: AMD Ryzen 7 1700
GPU: GTX 1070 Ti 8GB
RAM: G.Skill Flare X 16GB
PSU: Corsair RM850x
OS: Windows 10 Pro
If anyone can help me that would be greatly appreciated.

If I'm not mistaken, I should be getting consistent/near 800Mpbs speeds through ethernet every time, as I am the only person on the network. I've tried:
- using a different ethernet cable,
- using a USB wifi adapter,
- plugging my PC directly into the router,
- tried the different ethernet ports on the router,
- updating my Realtek PCIe GbE Controller drivers, but my speeds are the same.
- I tried going through Xfinity Assistant, and after restarting the router and running signal health checks, it told me my router is outputting my plan speed.
