Windows 10: Why did my internet download and upload speed decrease significantly after factory resetting

I factory reset once and everything was fine. The download speed for games was 20-40mb/s then after accidentally not being able to uninstall a certain app, I reset it again. After that point, my download speed was 5mb/s or less and I've tried ways to fix it, including watching videos, resetting, and factory resetting. However, none of it aided in any way. When I do an internet speed test, it says 17.9 mbps after and it used to be over 200.I have reinstalled Windows to the latest version and tried resetting the modem as well, but it has not workedI wanted to be able to fix this as I play big st

After windows 10 update the download speed is fine but why is the uploading speed decreasing?

But when there was Windows 7, both the downloading and uploading speeds of the net were fine. After updating to Windows 10, the upload speed has decreased.

Download speed decreased to 0.2mbit (from 6mbit) after upgrade from Win8 to Win10

Hello,

im experiencing very strange problem because download speed after upgrade to Win10 has decreased. Upload speed is still about 20Mbit/sec. I tried following:

• multiple network devices- Primary is LAN adapter, secondary LTE phone. Altough the ping is different and upload speed on LTE phone network is slower, both network connections suffer from very low speed (0.2Mbit). And yes, I tried different pc and
  
• newest drivers installed
• dns cleared
• antivirus uninstalled, no malware found. No improvement in speed either
  
• p2p update redistribution disabled

Before reverting back to Windows81, do you have any suggestions?
