| How to Increase Internet Speed Using Command Prompt |
Introduction
Is your internet speed slow and frustrating? While you may think upgrading your internet plan is the only solution, you can actually increase internet speed using Command Prompt (CMD).
The Command Prompt (CMD) is a powerful tool in Windows that allows users to tweak network settings, reset connections, and remove congestion for a faster, more stable internet connection.
In this guide, we’ll show you step-by-step CMD commands to speed up your internet, reduce lag, and optimize your network connection.
