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.

Sorry, I mixed your problem with a similar one ...

1 ) Try this, right-click on Windows start menu and go Settings.
Open Network & Internet
Select Proxy in the left pane. In the right pane, disable all options.

2 ) Disable Windows Auto-Tuning Feature
Open windows start menu and type: cmd
Right-click on " command prompt " and select Run as admin
Type this following command: netsh interface tcp show global
Look for the "Receive Window Auto-Tuning Level feature" , if it If it is displayed as 'normal' please deactivate it as follows:
netsh int tcp set global autotuninglevel=disabled

Now check if the speed is ok.

3 ) Disable Large Send Offload
Right-click again on Start button and select " Device manager "
Double-click on your Network Card and click on the Advanced tab
In the drop-down list, select Large Send Offload V2 (IPv4) and set the value to Disabled
Do the same for Large Send Offload V2 (IPv6)
Click OK.

Check your dns settings.

Press Windows + r keys and type: NCPA.CPL
Right-click on your network card and select Properties
Select Internet Protocol Version 4 (TCP/IPv4) and go to Properties.
Checks if the 'obtain an ip .... and Obtain DNS server ....' box is checked on automatic. This must other on auto.

You can do a test with the google dns if you check Use the following DNS
Google's Public DNS addresses 8.8.8.8 and 8.8.4.4
Disable Large Send Offload

This worked for me

I'm curious how you had it be not normal as Windows default is set to normal. Probably your real issue was some tuning software or something changing it in the first place. Windows 10 by default doesn't limit the speed. It can easily achieve the highest speed without any change.
