How to check your internet speed

Understanding Internet Speed Metrics 

Internet speed refers to how quickly data is transmitted over your connection. It is typically measured in megabits per second (Mbps) and is influenced by various factors, including your internet plan, network congestion, and the type of connection you use. The key metrics to understand are: 

• Download Speed: Measures how fast data is transferred from the internet to your device. This affects activities like streaming, downloading files, and browsing. The higher the download speed, the smoother the experience. A good download speed depends on your needs

• Upload Speed: Determines how quickly data is sent from your device to the internet. This is crucial for video calls, uploading files, and online gaming. A good upload speed ensures seamless communication and data sharing. Most home internet plans offer significantly lower upload speeds than download speeds, so if you frequently upload large files or engage in video conferencing, you may need a higher-tier plan. 

• Latency/Ping: The time it takes for data to travel to a server and back, measured in milliseconds (ms). Lower latency is better, especially for gaming and video conferencing, as it reduces lag and enhances real-time interactions. Anything below 20ms is considered excellent for gaming, while latencies above 100ms can result in noticeable delays. 

Choosing a Speed Test Tool 

There are several reputable tools available for checking internet speed. Popular options include: 

• Ookla Speedtest – One of the most widely used speed test tools, offering detailed metrics, historical data tracking, and server selection. 

• Fast.com – A simple, Netflix-backed tool focusing on download speed, ideal for streaming users looking to optimise their video playback quality. 

• M-Lab Internet Speed Test – Backed by Google, offering accurate and unbiased results, making it a reliable choice for general internet speed testing. 

• [Google Speed Test] – Easily accessible through Google search, providing a quick and straightforward test without additional features. 

Factors to Consider When Selecting a Tool 

• Ensure the tool measures both download and upload speeds. 

• Look for tools that provide latency and jitter data for a more comprehensive analysis. 

• Consider tools that allow the selection of different server locations to assess speed variability. 

Step-by-Step Guide to Performing a Speed Test 

1. Prepare Your Device and Connection 

   -Close unnecessary applications and browser tabs to free up bandwidth. 

   -Pause any active downloads, streaming activities, or background updates. 

   -If possible, connect your device directly to the router using an Ethernet cable to eliminate wireless interference. 

   -Restart your router and modem before running a test for the most accurate results. 

2. Access the Chosen Speed Test Website 

   -Open your browser and navigate to your preferred speed test tool. 

3. Initiate the Test 

   -Click the “Start” or “Go” button to begin the test. 

4. Wait for Results 

   -The test will measure your download speed, upload speed, and latency within a few seconds. 

   -Some tools may also provide information about jitter and packet loss. 

Interpreting Speed Test Results 

• Download and Upload Speeds: Compare these to your internet plan to ensure you’re receiving the speeds promised by your provider. If speeds are significantly lower, troubleshooting may be necessary. 

• Latency/Ping: High latency can cause noticeable lag, particularly in online gaming and video calls. Lower latency is preferred for real-time applications. 

• Jitter: This measures the variation in latency. A high jitter value indicates an unstable connection, which can lead to buffering and delays. 

• Packet Loss: Some speed test tools provide packet loss data, which indicates whether data packets are being dropped. High packet loss can result in poor video calls and laggy gaming. 

Tips for Accurate Speed Test Results 

• Close unnecessary applications and browser tabs that may be using bandwidth in the background. 

• Use a wired connection instead of Wi-Fi to get the most accurate readings. 

• Test on multiple devices to see if speed issues are device-specific. 

• Perform tests at different times of day to identify possible network congestion. 

• Stand closer to your router if using Wi-Fi to reduce signal interference. 

• Conduct multiple tests over a few days and average the results for better accuracy. 

• Restart your modem and router before testing to clear any temporary network issues. 

• Use different test servers to compare results and get a better overall picture of your connection quality. 

Four Types of Internet Tests 

1. Download and Upload Speed Test – Measures how quickly data is sent and received, affecting browsing, streaming, and file transfers. 

2. Jitter Speed Test – Evaluates the consistency of your connection, with lower jitter indicating more stable performance. 

3. Ping or Latency Test – Determines responsiveness, crucial for gaming, VoIP calls, and video conferencing. 

4. Streaming Speed Test – Measures how well your connection handles video streaming without buffering or degradation in quality. 

Common Factors Affecting Speed Test Results 

• Network Congestion: More users online at the same time can slow down speeds, especially during peak hours. 

• Wi-Fi Interference: Walls, other wireless devices, and distance from the router can weaken signal strength and impact speed. 

• Device Limitations: Older devices may not support high-speed connections, leading to slower test results. 

• Server Location: The distance between your device and the test server can influence results. Choosing a closer server typically gives more accurate readings. 

• Router Performance: Outdated, overloaded, or improperly configured routers may bottleneck your connection, affecting overall speed. 

• ISP Throttling: Some internet service providers may intentionally slow down certain types of traffic, impacting test results. 

• Background Applications: Software updates, cloud backups, and other background activities can consume bandwidth, affecting speed test accuracy. 

• Cabling and Hardware: Faulty or outdated cables and networking hardware can reduce speeds even if your ISP provides high-speed service. 

Conclusion 

Regular internet speed tests help ensure you are receiving the speeds you pay for and allow you to troubleshoot potential issues with your connection. By understanding your speed test results and optimising your setup, you can enhance your browsing, streaming, gaming, and overall online experience.

If your speeds are consistently lower than expected, consider upgrading your router, switching to a wired connection, or contacting your internet service provider for further assistance.  

Keeping an eye on your internet speed helps maintain a fast and reliable connection for all your digital needs. Additionally, being aware of factors that impact speed can help you make informed decisions when upgrading or optimising your home network.
