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.

HAHAHAHA! YOU ARE A LEGEND!
After first reading your comment i thought nah this wont work. But i have had this issue for 2 weeks now and was fed up.
And praise the lord and all other beings it actually worked?!?
I dont how, i dont know why but it worked!
I thank you my friend.
Couldn't believe it, but I had tried everything else. I tried this as well, and it worked for me. Worth a shot if you are at the end of your wits like I was!
Thanks for posting!
'netsh int tcp set global autotuninglevel=normal'
This fixed it for me. Thanks!!
None of the things that you mentioned helped my Laptop (HP Spectre x360 13t) but surprisingly enough there was an option in Device Manager>"Your Network Card">Advanced>Energy Efficient Network
Which was Magically limiting both My WIFI and Lan Cable(Through a USB C dongle) to 35Mbps constantly.
