Yeah, the ol' reboot method of fixing things. Unplug the router and modem (if you have separate ones), leave them unplugged for 10-15 seconds, then plug them back in. Wait a few minutes before trying again and then see if it works. Do you have decreased download speeds watching YouTube or Netflix as well? Or is it just Steam/Origin? If you are watching a YouTube video, set it to the highest quality setting (1080p or 4K even) and right click on the video and select 'Stats For Nerds.' It should show you your download rate. If that's normal and Origin/Steam are still slow, it's probably your ISP. You said you had just reinstalled Windows? Are you downloading a bunch of other stuff too? By chance do you have Star Citizen, and are you updating that? The Star Citizen updater seems to ignore the download limit that you can set and will completely saturate your connection.
I rebooted my computer, turned off the router, and left only the Steam running. The issue remains unchanged. I’m considering waiting until tomorrow to see if it resolves on its own. I haven’t noticed any drop in download speeds while watching YouTube or Netflix, but I’m not sure.
I verified through YouTube that the download speed remains consistent at 3mb per second.
It seems strange. You might want to contact your ISP. Although it’s unlikely, it’s possible the Steam/Origin servers are under heavy load. Begin your downloads before bedtime tonight and let them run continuously. Review the situation tomorrow morning and reach out to your ISP if performance remains poor.
It shouldn't really affect things with platforms like Steam, Origin or UPlay. If they ask to restart after setup, it could be useful to install one at a time and turn it off afterward; though I don't think it's a big deal. Edit: After restoring W10, verify that your regular internet connection isn't mistakenly marked as a limited plan.
