Slow Internet After Upgrading to Windows 10 Anniversary Update?

After upgrading your system to Windows 10 Anniversary Update you may have noticed a drop in internet connection speed.

Due to Auto-Tuning that first appeared since Windows Vista and is still available in Windows 10.

The purpose of Auto-Tuning is to manage the programs that receive TCP data on a network to improve the performance of processes tasked with they. In the Windows 10 Anniversary Update, however, it seems to also cause an unexpected drop in Internet speed.cable slow internet Windows 10

The solution is to disable the function and can be done with a simple command in a command-line window with administrator privileges.

Open a Command Prompt window by right-clicking on the of Windows. Click on the option that says Command Prompt with administrator rights.

First of all, we need to check the status of Window Auto-Tuning, with the following command in:

netsh interface tcp show 

Look for the option "Receive Window Auto-Tuning Level," and if set to "enabled," you'll need to change it to "disabled."

To do this, type the following command:

netsh int tcp set  autotuninglevel=disabled

Immediately then try your Internet speed to see if there is a noticeable improvement. If you do not see a difference you can easily turn the "Receive Window Auto-Tuning Level" to "enabled" with the following command:

netsh int tcp set global autotuning = normal

What is also important to know is that if this feature is already disabled and you have a slow Internet connection after installing the Windows 10 Anniversary Update, you should start looking elsewhere, such as what are the processes of connecting to network running longer than usual, the or firewalls.
