I have a PC running windows 10, all of the latest updates have been installed and drivers are up to date and it is connected to a ethernet cable for internet. I have a gigabit ethernet service. When I run an internet speed test I get somewhere between 14 -40 Megabits/sec download and 15-30 Megabits/sec upload (on a good day). When I connect my laptop to the same ethernet cable my download speed is between 650 and 750 Megabits/sec and my upload is closer to 50 Megabits/sec. I have tried many suggestions online such as turning off automatic updates, and removing the reserve bandwidth for updates. changing the network adaptor settings to force gigabit speed rather than auto assign. I have even tried installing a new gigabit network card to see if it was a motherboard issue and no luck. I cant seem to find anything online to help me resolve this issue. Please help.

That actually solved my problem, thanks
Hi, I was experiencing the exact same- I could plug my work laptop into exactly the same ethernet cable and get my ISP max of 500 mb/s- but on my desktop I was only getting 140-175 on average. I googled and searched, did countless cmd prompts and scans etc- nothing seemed to help.
Finally, I decided- I'll uninstall the network card and restart windows- see if this helps. And sure enough, after removing the network card drivers, and reinstalling (this is done automatically when you startup windows again) I am now getting max out of my desktop pc. I hope this also helps you and others if experiencing the same issue.
Hello,
I had the same issue and tried disabling autotuninglevel first. After struggling on other several failed attempts on device config and tutorials, I read this comment and set the autotuninglevel back to normal as well. So I got the problem instantly fixed.
Thank you very much for your contribution!
Cheers.
