Windows 10 limiting my internet speed?

Anonymous

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.

Hello,

I had same issue. It was solved for me via following command in cmd. Previous value was disabled.

netsh int tcp set global autotuninglevel=normal

Same problem here. Been getting about 90-100, which is fine for this machine. About once per month, speed goes to 8-20. Reset modem, etc. and it s fine for a while. Three days ago it dropped to 8-16 for 2 days; then yesterday it went to 90-100 with me doing nothing. Today its 8-20.

The problem is that my tablet (android) gets 140-160 sitting beside the desktop, so the problem is in the desktop, running W 10.

I tried several of the above; some did not work; i.e., DLL not working.

Anybody have any ideas?
