Understanding Your Internet Speed: What Do the Numbers Mean?

Running an internet speed test is the quickest way to check the health of your connection. But what do all those numbers-download, upload, ping-actually mean? Understanding these core metrics helps you determine if you’re getting the bandwidth you’re paying for and whether your connection is strong enough for activities like streaming, gaming, and working from home. This guide will break down your results in simple terms.

The Core Metrics Explained

Your broadband connection isn’t just one speed; it’s a combination of different factors. Here’s what you need to know:

  • Download Speed (Mbps): This is the most commonly advertised number. It measures how quickly you can pull data from the internet to your device. Think of it like drinking water through a straw-a higher download speed means a wider straw, allowing you to stream movies in 4K, download large files quickly, and browse websites without waiting.
  • Upload Speed (Mbps): This measures how quickly you can send data to the internet from your device. This is crucial for video calls, sending large email attachments, uploading videos to YouTube, and online gaming.
  • Ping (Latency) (ms): Ping is the reaction time of your connection, measured in milliseconds (ms). It’s the time it takes for a data packet to travel from your device to a server and back. A low ping is critical for online gaming and real-time communication, as it reduces lag and creates a smoother experience.
  • Jitter (ms): Jitter measures the consistency of your ping. A low jitter means your connection is stable and reliable. High jitter can cause glitches, buffering, and choppy audio during video calls, even if your download speed is high.

How to Get the Most Accurate Internet Speed Test Results

To ensure you get a reliable reading of your connection, follow these simple tips before you test:

  1. Limit Other Activities: Close applications, browser tabs, and stop any downloads or streams on other devices using your network.
  2. Use a Wired Connection: For the most accurate result, connect your computer directly to your router using an Ethernet cable. A Wi-Fi speed test can be affected by distance from the router and physical obstacles.
  3. Restart Your Router: If your results are much slower than expected, a quick reboot of your router can often solve connection issues.
  4. Run Multiple Tests: Perform the internet speed test a few times throughout the day to get an average reading, as network congestion can affect speeds during peak hours.

Frequently Asked Questions (FAQ)

This tool uses the embedded technology from Fast.com, which is powered by Netflix. It measures your connection’s speed by performing a series of downloads from and uploads to Netflix’s global network of high-speed servers (Open Connect). Because Netflix has servers all over the world, this provides a highly accurate and reliable internet speed test from almost any location.

There are several reasons why your internet speed test results might be lower than your plan’s advertised speed. Common factors include: Wi-Fi interference, being far from your router, using older hardware (router or device), network congestion in your area, or testing during peak internet usage times (like evenings). An ethernet connection will almost always provide a faster result than Wi-Fi.

This is a common point of confusion. “Mbps” stands for Megabits per second, which is the standard unit for measuring internet speed. “MBps” stands for Megabytes per second, which is used to measure file size. There are 8 bits in 1 byte, so a 100 Mbps connection can download a 12.5 MB file in one second (100 / 8 = 12.5).

It’s a good idea to run an internet speed test whenever you feel your connection is slow, after you upgrade your internet plan to confirm you’re getting the new speeds, or when you’re setting up a new router to find the best location for optimal Wi-Fi coverage.
