Windows 10: Need help solving weak download speeds

Recently I noticed my download speed is around 10-15 Mbps. It was 100-110. My dad is paying for 100 down and 5-6 up. My upload is fine but my down is terrible. I called Xfinity and they replaced the coax cable. Keep in mind that my router would go out from time to time, but was fixed after replacing the coax cable, eliminating the factor that my router is bad. I have a C7800. I started thinking it may be my wifi adapter linked to my pc. It also may be a windows update, but I cant test it since I cant roll back updates. I will be adding all the pictures I think are relevant. Sorry if I sound like a noob, but I'm 15 and I know a bit of tech, but barely of internet stuff.


If you would like, I can screen share on discord.

Slow Download Speed

Hi,

Thank you for posting your query in Microsoft forums.

• I would suggest you to test the speed using any of the speed test website or app to confirm the upload and download speed.
• I also suggest you to reset the wireless router to check if that helps.
  
• You may plug in the Ethernet cable if available and check the speed.
  

Hope the information is helpful. Feel free to write to us for any other assistance with Windows, we’ll be glad to assist you

Browsing speed is fast, but download speed is 0

I'm currently using Windows 10 and netcomm nb604n router.

Problem:
Web browsing on chrome/edge/firefox works fast, but my download speed from majority of websites start around 10kb/s and eventually (in a few minutes) decrease to 0kb/s.

Here are some example files that does this:
https://atlas.hashicorp.com/laravel/boxes/homestead/versions/1.0.1/providers/virtualbox.box
Git for Windows (there is a download button)

When I am downloading from utorrent, or when I installed the Unity engine through Unity's installer, my download speed was fine.

Things that I have tried:

1. Running the test on speedtest.net. It says that my download speed is 18MB/s and upload speed is 1Mb/s. Of course this doesn't demonstrate the actual speed that I'll get when downloading/uploading from a server, but my ISP is using this to say that there is no problem on their side.
   
2. Taking my router, filter, and all cables to another house and downloading the same files that I couldn't download. This worked perfectly fine, so I'm guessing that my equipment is not the issue.
   
3. Using both wireless and LAN on a brand new computer and an old laptop. The problem exists in all cases.
   
4. Resetting and restarting the router. Did not do anything.
   
5. Changing the mtu settings as suggested on Windows 7, download speeds drop to 0 kb/s and the download has to be restarted
   Unfortunately this didn't solve my issue.
   
6. Calling my ISP to make sure that they weren't throttling my network. They are denying any fault on their end, and are claiming that there is something wrong with my computer or my router but refusing to provide a solution.
   

If anyone has any suggestions or ideas on what I could try to resolve this issue, please let me know!
