Let’s dive straight into the article on how to increase internet speed using cmd windows 7. Although this article is specifically based upon windows 7. The similar steps can also used in your windows xp/7/8 operating system.
Before getting into the article you need to know that there will be a lot of reasons for slow internet speed. The most common reasons would be internet company’s server issues, old modem..etc. But, still there is always room for some optimization.
So, in this article let us see the best ways to speed up your internet connection in windows 7 using cmd.
Using Netsh command
Netsh is a command scripting utility which can be used to change the network configuration of your computer. Now, we will be using this netsh command to change the configuration of our TCP.
Step 1: Open your cmd (command prompt) as administrator
Open the windows start menu and search for cmd. Once you find the cmd right click on it and click the “run as administer” option.
Step 2: View TCP global parameters
To view the current settings of your os type in “netsh int tcp show global” and press enter. You will be show the current values set for the TCP global parameters.
Step 3: Enable Chimney offload state
Chimney offload is used in transferring processing tasks from CPU to network adapter. In layman’s terms this feature is used to reduce the load in the CPU. So, it is logical that this option should be set to enabled.
To do that type in the command “netsh int tcp set global chimney=enabled” and press enter, this command enables the chimney option.
You can learn more about chimney offload settings at Microsoft chimney offload information.
Step 4: Changing Auto-tuning level settings to normal
There is something called TCP receive window (RWIN) in your computer. Which determines the amount of data received by your PC without acknowledgement.
Now, auto-tuning needs to be specified to tell our OS on how to handle RWIN. To change this setting type-in the command “netsh int tcp set global autotuninglevel = normal” and press enter.
Step 5: Enabling Add-on congestion control provider
To understand this you need to know how data is transmitted in the network. To prevent congestion data is transmitted in small blocks by TCP. Enabling this setting helps in controlling and preventing congestion.
To enable this setting type in the command “netsh int tcp set global congestionprovider=ctcp” and press enter.
The above steps are the best steps to optimize and speed up your internet connection using command prompt (cmd).
