Software recommendation: optimize TCP/IP for Internet speed

The TCP/IP protocol is the main protocol we use when surfing the Internet, but many people usually do not know much about it. In fact, it is very close to our network operation, so we need to optimize its settings, and thus make better use of the network bandwidth. Next, we will use a professional website with professional optimization software to do the operation.

Analyze and determine the current network parameters

First of all, open the home page of SpeedGuide Cloud Service (, where you can see many functions. Now we click on the “TCP Analyzer” button to start the analysis of the current network. Once the analysis is complete, we can see the IP address, operating system version, and browser version of the current network in the web page. At the same time, at the bottom of the page, we can see the optimization reference data of the cloud service for the current network. These include MTU, MSS, RWIN and other details, which allow us to perform further optimization operations (Figure 1).


Tip: In order to make the analysis of this cloud service more accurate, it is recommended that you do not perform other network operations while performing data analysis. It is also best to turn off ad filtering software or extensions to avoid unnecessary interference with the analysis of the cloud service.

Enter the parameters to complete the optimization settings

Now, click the “TCP/IP Optimizer” link in the list on the left side of the analysis page, and you will see a new pop-up page with an optimization software called “TCP Optimizer”, through which we can write the We can write the parameters we just analyzed into the system. We first click on the “General Settings” tab in the optimization software, and drag the slider of the “Connection Speed” option with the mouse to make it correspond to the bandwidth size of the network you are currently using. We are now using 100 megabits of bandwidth, so we will slide to the “100+Mbps” option here (Figure 2).


Next, click on the “Custom” option at the bottom of the optimization software, so we can see that all the parameters in the window are in an editable state, and then we can set them one by one against the parameters in the optimization page. Suppose the MTU=1460 is given in the optimization page, we can set the MTU parameter to 1460. If “Time to live left=111 hops”, then set it to 111 in the “Time to live” input box. Once all settings are completed, click the “Apply changes” button below and a dialog box will pop up asking if you want to reboot the system (Figure 3). Click “Yes” to restart the operating system immediately, and then you can complete the optimization of the network parameters.


Tip: If the user finds the above steps too tedious, then you can directly select the “Optimal” option in the optimization software, and then the software will automatically optimize the network settings. If the network is found to be unstable after optimization, then you can click on the “Windows Default” button of the software to restore the parameters to the system default values.
