All internet service providers promise blazing-fast internet speeds, low latency, and excellent reliability, but how many really deliver on their promises? If you’re suspecting that your internet service provider isn’t living up to its promises, you should perform an internet speed test to gather accurate data and either verify or eliminate your suspicion.
What Is Internet Speed?
Internet speed indicates how fast data packets travel from your device to the internet and from the internet to your device.
When measuring internet speed, it’s useful to distinguish between download speed and upload speed. The former indicates how quickly you can retrieve data packets from the internet (i.e. download a file), while the latter indicates how quickly you can send data packets from your device to the internet (i.e. upload a file).
How much internet speed you need depends on multiple factors, including your usage habits and the number of people sharing the connection. Here are general internet speed requirements based on common online activities:
- Email and web browsing: 1–5 Mbps
- Online gaming: 10 Mbps
- HD streaming: 15–100 Mbps
A symmetrical internet connection (identical download and upload speed) is preferable to an asymmetrical internet connection (smaller upload speed than download speed).
How Is Internet Speed Measured?
Internet speed measuring isn’t complicated:
- A connection is established between your device and a remote server.
- The transfer of a nominally sized file is initiated (100 MB is a common size these days).
- The time it takes for the transfer to complete is measured.
- The size of the file is divided by the transfer time.
- The result is converted to Mbps.
For example, if it takes you 10 seconds to download a 100 MB large file, then you have a download speed of 10 MBps. Because 1 MBps (megabytes per second) equals 8 Mbps (megabits per second), your download speed is 80 Mbps.
How to Select an Internet Speed Test Service
There are many internet speed test services out there, and their quality varies greatly. If you want to obtain the most accurate results possible, you should always choose an independent internet speed test and not one provided by your internet service provider.
Why? Because internet service providers sometimes prioritize their own internet speed test services to influence the results. Here are several official internet speed test services for popular internet service providers:
- AT&T High Speed Internet Speed Test
- Comcast Speed Test
- FrontierNet Network Speed Test
- Grande Communications
- RCN Speed Test
- Spectrum Speed Test
- Time Warner Cable Speed Test
- Wave Broadband
- XFINITY Speed Test
Instead of these internet speed test services, we recommend you choose any of the 10 independent internet speed test services listed below.

The accuracy of these services generally depends on numerous factors like server proximity, network congestion, and the quality of the user’s internet connection. Most internet speed test providers like Speedtest by Ookla employ comprehensive testing methods for reliable results.
Speed test services typically measure download speed, upload speed, and ping or latency, which are the key metrics for understanding an internet connection’s performance.
Yes, many of the top services provide mobile apps. For instance, Speedtest by Ookla and FAST.com have apps that users can download on both iOS and Android devices for testing speeds on cellular or Wi-Fi networks.
A wired connection usually provides a more stable and faster internet speed, resulting in better test results compared to a wireless connection, which can be affected by interference, distance from the router, and other factors.
For the most precise measurements, it’s recommended to connect your device directly to the router with an ethernet cable when performing an internet speed test.
Using a VPN can potentially slow down your connection due to encryption overhead and the distance to the VPN server, which might affect speed test results.
To get a baseline of your internet speed, it’s best to perform tests at different times of the day. However, testing during off-peak hours can sometimes provide the best results due to less network congestion.
Regularly testing your internet speed, especially after making changes to your network or if you’re experiencing connectivity issues, can help you monitor your service’s performance.
A good download speed for streaming is typically 5-25 Mbps for standard or HD content, respectively, while gaming generally requires a minimum of 3 Mbps; however, faster speeds and lower latency are preferred for a better experience.
Some services, such as Speedtest by Ookla, allow users to create an account to track and save past test results for future comparison.
Yes, older hardware or devices with limited processing power may not accurately reflect the full capacity of your internet connection’s speed.
Ping or latency is crucial for activities that require real-time data exchange, like online gaming or video conferences, as it measures the responsiveness of your connection.
Download and upload speeds are measured in Mbps, with higher numbers indicating faster speeds. A lower ping, measured in milliseconds, signifies a more responsive connection.
Most internet speed tests are designed to work across various connection types, but some connections like satellite might exhibit more variability due to factors specific to their technology.
Different services may have distinct server locations, testing algorithms, and conditions, which can lead to variance in results. It’s a good practice to use multiple services for a well-rounded view of your internet speed.
Yes, many services provide the option to share your results, which can be useful for troubleshooting purposes or to validate speeds with your internet service provider.
If your internet speed test results are persistently below your provider’s advertised speeds, you should contact them to discuss the discrepancy. Ensure that you’ve eliminated local network issues within your control before reaching out.
Servers act as the destination for your data during the test, with proximity to these servers affecting the speed and latency results. Hence, choosing a server close to your physical location can yield more accurate results.
