How to Test Internet Speed Accurately

Running a speed test is a common way to check your internet performance, but are you doing it right? Many factors can impact the accuracy of the results. In this article, we explain how to get the most precise readings for your download, upload, ping, and jitter speeds.

1. Use a Trusted Speed Test Tool

Start by choosing a reliable tool or website like:

Ensure the tool uses servers close to your location to minimize external network delays.

2. Test with a Wired Connection

Wi-Fi introduces interference, signal loss, and congestion that can reduce test accuracy. For the most reliable result, connect your device directly to the router using an Ethernet cable.

If you're testing Wi-Fi speed specifically, make sure you're near the router and no other devices are using the network.

3. Close Background Applications

Programs that use the internet in the background — like cloud sync apps, updates, and streaming — can interfere with your speed test.

4. Restart Your Modem and Router

A fresh reboot clears up memory and resets network processes, potentially improving performance before testing.

5. Perform Multiple Tests

Run the speed test multiple times during the day — morning, evening, peak hours — to get a better overall picture. Networks can vary depending on congestion and time of use.

Take at least 3 tests and average the results for a more accurate estimate.

6. Choose the Right Server

Most test tools let you manually select a server. Try testing both local and distant servers to see the impact of distance and routing on latency.

7. Understand the Metrics

8. Test on Different Devices

Device limitations like weak Wi-Fi chips, background apps, or older hardware can skew results. Test on multiple devices to compare and verify consistency.

9. Disable Power Saving Modes

Some laptops or phones throttle network performance when in battery-saving modes. Make sure full performance is enabled during testing.

10. Compare with Your ISP Plan

Check your internet service provider's plan speed and see how close your results are. If you consistently get much lower speeds, consider contacting your ISP.

Conclusion

Accurate speed testing is more than just clicking a button. By eliminating interference, optimizing your setup, and understanding what the results mean, you’ll get a clearer picture of your internet performance. Whether you’re troubleshooting, comparing providers, or optimizing your setup, these tips will ensure your test results are accurate and meaningful.
