How To Increase Internet Speed using CMD

First thing to test, is your internet connection. We do this, by using Ping. Ping is a Windows program that comes pre-installed with the OS. It is a text based program and therefore needs text based commands to execute.

The first thing to do, is open the Start Menu and search for the command prompt. You can do this by typing “cmd” in the search box and hitting enter. Once you have the command prompt open, you can use Ping to test your connection. Enter the command ping

Once typed, hit Enter and wait for your command prompt to look like the image below. Do note, that the results are not displayed instantly, so you might have to wait a while for the results to pop up.

Step 1: Open the command prompt in the way already discussed and type netsh int tcp show global and hit enter.

Step 2: The next step is to change the default TCP parameters. Open your notepad and enter the following lines

netsh int tcp show global
netsh int tcp set global chimney=enabled
netsh int tcp set heuristics disabled
netsh int tcp set global autotuninglevel=normal
netsh int tcp set global congestionprovider=ctcp

Step 3: Save this file with the name Boostspeed.bat

Step 4: Run this file in administrator mode and once the changes take effect, you should notice an increase in your internet speed. Users have reported an increase of upto 35% at times after these steps. Hopefully they might work for you as well.

Step 5: Just in case you wish to revert back to the default TCP parameters or have the option to revert back if ever needed, you can save the following lines in another .bat file.

netsh int tcp show global
netsh int tcp set global chimney=default
netsh int tcp set heuristics enabled
netsh int tcp set global congestionprovider=none
