How to improve internet connection speed by clearing DNS cache memory.

We certainly depend on the Internet more than ever. Whether for telework, leisure, shopping, or searching for information. Therefore, it is advisable to improve the connection speed. In fact, it is likely that after a while you will notice that it goes slower than usual. For this reason, web pages load slower. Likewise, video calls are slower. Consequently, it is time to clear the DNS cache of Windows 10. And this is the topic of this post. Today we will see how to improve internet connection speed by clearing DNS cache memory.

What is DNS cache memory and how to clear it?

The system stores in this cache the most used DNS addresses and domain names. Consequently, every time you return to those websites, Windows does not need to go to the DNS servers to look up the location. This makes websites load faster. So far so good. The problem is that sometimes this cache gets corrupted or has outdated information. In such a case, it produces the opposite effect, slowing down the connection. Why does this happen? Well, Windows looks for the information in the DNS cache, notices that it is corrupted, then goes to look for it in the DNS server. This wastes valuable time. The solution is to clear the Windows DNS cache to delete the corrupted data

To execute this process, it is necessary to execute some commands in the console. In addition, you can do it from the command prompt or the PowerShell. The only requirement is that you have to do it with administrator privileges. Well, for this example we will use PowerShell. With this intention, press the Win+X combination.

Open a PowerShell with administrator privileges

Additional steps to improve your internet connection

Let’s apply other commands to improve the internet connection status. First, we will renew the IP address of the computer. To do this, run the following command:

ipconfig /renew

Finally, reconfigure the Windows 10 connection winsock protocols. Sometimes these change when Windows is updated. It is necessary to restart the computer to complete the operation.

netsh winsock reset

It is likely that at the beginning you will notice a slower loading of the pages. This is logical since we have cleared the DNS cache. Consequently, Windows has to fill it again with the most used services. However, after visiting them several times, the cache will be optimized. And consequently, we will see how the internet connection will improve. Okay, so we have seen how to improve the internet connection by clearing the DNS cache memory. It is advisable to do this action every two or three months to ensure the online performance of Windows 10. See you soon!
