Boost Your Internet Speed Using CMD: 4 Quick Fixes That Actually Work

Ever feel like your internet connection isn't living up to its full potential? You've got the bandwidth, but pages load slowly, and downloads crawl. While many factors can affect internet speed, sometimes the solution is hidden right under your nose, accessible through a powerful, often overlooked tool: the Command Prompt (CMD).

Don't worry, you don't need to be a tech wizard to use these tricks. They're straightforward, take just a few minutes, and can significantly improve your browsing and download experience.

Let’s dive in.

1. Refresh Your IP Address (Especially for Wi-Fi Users)

Think of your IP address as your internet's street address. Sometimes, especially on Wi-Fi, your connection can get a bit "stale." Giving your system a fresh IP can resolve minor connectivity hiccups.

Open CMD and run:

ipconfig /release
Enter fullscreen mode Exit fullscreen mode

This command tells your computer to let go of its current IP address.

ipconfig /renew
Enter fullscreen mode Exit fullscreen mode

This one requests a brand new IP address from your router.

✅ This simple refresh can often give your Wi-Fi a noticeable boost (though its impact on wired connections is minimal).

2. Clear Out Your DNS Cache

Your computer keeps a "phonebook" of websites you visit, called the DNS cache. This speeds up future visits by remembering their IP addresses. However, the cache can become outdated or corrupted, leading to slower loading times.

In CMD, type:

ipconfig /flushdns
Enter fullscreen mode Exit fullscreen mode

✅ You might notice a tiny delay at first, but soon after, websites should load faster and smoother.

3. Fine-Tune Your TCP Settings for Optimal Downloads

TCP (Transmission Control Protocol) controls how data is transmitted. Windows has a setting called Receive Window Auto-Tuning Level that optimizes this.

To check the current setting:

netsh interface tcp show global
Enter fullscreen mode Exit fullscreen mode

Look for: Receive Window Auto-Tuning Level

If it's not set to normal, set it manually:

netsh int tcp set global autotuninglevel=normal
Enter fullscreen mode Exit fullscreen mode

✅ This ensures Windows adjusts data flow dynamically, leading to more efficient downloads.

4. Disable Windows Scaling Heuristics for Unrestricted Speed

Windows may apply certain “heuristics” that can limit your internet speed under specific conditions.

Check its status:

netsh interface tcp show heuristics
Enter fullscreen mode Exit fullscreen mode

If it’s enabled, disable it:

netsh int tcp set heuristics disabled
Enter fullscreen mode Exit fullscreen mode

✅ You’ll see “OK,” confirming heuristics are now disabled for maximum performance.

See the Difference

After applying these simple CMD tweaks, you may be surprised by the improvement in your internet speed. These quick fixes require no specialized knowledge and can significantly enhance your online experience — from faster browsing to smoother downloads.
