How to Increase Internet speed by using CMD

To increase the speed of internet by using cmd, pinging to the default access and using ‘netsh int tcp’ command beside with changed features to increase the internet speed.

Increase Internet speed by using CMD

Many times we face problems with the slow internet speed and we actually do not identify the problem and how we can increase the speed. Most people restart devices or the internet router and then think that it will increase internet speed.

Mostly I do not work in our cases but we still believe that restarting is the correct way to increase internet speed if it wants down. Some people complain to the internet service provider companies but they still face same speed. Most of the internet users in some countries are facing this problem like India, Pakistan, Bangladesh, Nepal and Afghanistan. So, today we are giving some step by step guidance for internet speed increasing by using cmd option.

How to speed up internet using cmd:

  • Check internet speed using cmd pings to default gateway

You can check your internet connection speed by sending ping packets to your default gateway.

To know your default gateway, you can use ipconfig /all command. Once you get the IP address of your default gateway, start running a continuous ping by typing ping -t <your default gateway address>. The time field value will show you the time taken to get an acknowledgement from the gateway.

Lower time value is an indication that your network is faster. However, running a lot of pings consume network bandwidth as well as your default gateway resources. Though the data packets for ping are very negligible in size and you might not observe any change in internet speed but it does consume bandwidth.speed-up-internet-connection-using-cmd

  • IP release and renew

Well, If you are using a WiFi connection, in the case of IP release and renew, you may experience a temporary speed boost, depending on the strength of the WiFi signal. Though, in the situation of LAN, it won’t affect speed.


  • Flushdns to Speed up the internet using cmd

Our computer maintains a list of the websites and their corresponding IP addresses that we access the most in the DNS resolver cache. Sometimes, these data become obsolete after months or weeks. So when we flush our DNS resolver cache, we actually flush out the obsolete data and make new entries in the DNS resolver cache table.

Using this command may be initially experiencing a slower connection because of the requirement of the new DNS lookups for every resource. However, you will soon experience faster loading of the websites in your browser.flush-dns-300x153@2x

  • Speed up the internet using cmd ‘Netsh int tcp’ command:

Type this command in your command prompt window and observe carefully:

If you do not see Receive Window Autotuning level as ‘Normal’ as shown above then run the following command:netsh-commands-cmd

  • netsh int tcp set global autotuninglevel=normal

This command will set your TCP receive window to Normal from the disabled or restricted state. TCP receive window is one of the key factors in the internet download speed. Thus making the TCP receive window to ‘Normal’ will surely help you in increasing your internet speed.

After this command, let’s check for the additional factor of Windows in relations of the slow internet connection called ‘Windows scaling heuristics’. To check for this parameter, type

  • netsh interface tcp show heuristics

Windows-scaling-heuristics-disableWell, in my situation, it’s disabled. However, in some case, you might it enabled. That means Microsoft in some ways, is trying to limit your internet connection. So dodge it and to get faster internet, type the underneath command and press enter:

  • netsh interface tcp set heuristics disabled

When pressed enter, you will get an ‘ok’ message and now you internet speed has surely got boosted up.

Once you are done with the above steps, you can follow step one again to measure the time value in getting a ping acknowledgement from the default gateway, just to check if your internet speed has gone up or not.
