While internet service providers are always quick to promise blazing-fast speeds and single-digit latency, the reality is often very different. Internet speed tests empower internet users to verify that they’re really getting the speeds they pay for, but it’s not easy to know which of the countless internet speed tests that are available on the web are accurate.



For this article, we’ve personally tested all major internet speed test online services to learn what their pros and cons are. But before we get to them, we want to explain how to do a proper internet speed test.

How to Do a Proper Internet Speed Test

You won’t be able to obtain good results even with the most accurate and reliable internet speed test out there unless you know how to do a proper internet speed test.

  1. Don’t use the internet while testing: This may sound obvious, but experience tells us that it isn’t. These days, even common household appliances connect to the internet, sometimes downloading large updates or uploading complex diagnostic information to remote servers. To obtain accurate test results, it’s paramount that you disconnect all devices except for the one used for the purpose of testing from the internet.


  1. Use multiple internet speed tests: Most internet speed tests are available for free, so there’s no reason not to use several of them to gauge the bandwidth performance at your residence truly. You may notice that some internet speed tests measure your latency on the higher side, which may have more to do with the performance of the servers on which the internet speed tests are hosted than your own internet connection.

  2. Optimize your network: It’s one thing to set up a Wi-Fi network, and it’s something else entirely to optimize its performance to perfection. With a tool like NetSpot, you can easily see all dead zones in your home and determine which wireless channel is cluttered the least. NetSpot works on Windows and macOS, and you can download it for free and use without any expert knowledge.
