How do I run a speed test?

How to run a broadband speed test, what Mbps means, and how to get an accurate reading.

This article explains how to run a speed test on your broadband connection and what the results mean.

What is a broadband speed test?

A speed test measures how fast data is uploaded and downloaded through your broadband connection. The result is shown in Megabits per second (Mbps). The higher the number, the faster your connection.

Mbps and MBps: what is the difference?

  • Megabits (Mb) measure internet download and upload speeds.

  • Megabytes (MB) measure the size of files, such as images or documents.

  • A Megabit is one eighth the size of a Megabyte. To download a 1 MB file in 1 second, your broadband speed would need to be 8 Mbps.

Tips before you run a speed test

For the most accurate results:

  • Use a wired connection. Connect your computer to the router with an Ethernet cable before running the test.

  • If testing over Wi-Fi, stay within three metres of your router with no large obstacles in between.

  • Run three tests on different days and at different times to get an average. This gives a more accurate picture of your broadband performance.- Close any applications or programs that may be using significant bandwidth, such as streaming services or large downloads, before running the test.

  • Ensure that no other devices are heavily using the internet connection during the test.

How to run a speed test

  1. Go to a speed checker such as fast.com.

  2. The test starts automatically and measures your download speed.

  3. Wait for the test to complete. Your download speed in Mbps will be shown on screen.4. The test also measures latency in addition to download and upload speeds.

  4. Compare the measured speeds to the speeds promised by your internet service provider (ISP). If there is a significant discrepancy, consider troubleshooting or contacting your ISP for support.
