The Global Broadband Speed Test

This data has been used by numerous publications in the analysis of internet access data rates around the world. To improve accuracy, Speedtest.net now performs tests via a custom protocol over test TCP sockets. The tests are performed within the user's web browser or within mobile apps.

• Based on this result, the speed test selects a larger file to perform the main download speed test.
• If speeds improve significantly, your Wi-Fi is the bottleneck.
• If latency is too high or speeds fluctuate, you may experience buffering, interruptions, or a reduction in video resolution.
• Disconnect anything you’re not using before you speed test your internet .

Yes, to get a more accurate reading you should limit your use of the internet while conducting the test. If you’re gaming or streaming, you may want faster internet. Your need for speed can vary depending on what you’re using your internet for.

Understanding your speed test results

Since Fast.com is owned and operated by Netflix and designed to simulate streaming performance, it’s a great test for anyone who wants to check whether their speeds hold up while binge-watching shows. Using their service-specific tests is convenient, but we recommend using one that’s independent from your provider for greater objectivity. However, the likeliest culprit is your home Wi-Fi connection, as wireless speeds will dip the farther you move from your router. Previously, our scoring system relied on subjective peak-speed figures and basic idle ping tests. However, in most cases, we’d recommend using a third-party speed test, most of which will offer deeper insights and better control over how the test runs. For instance, running the router app’s speed test is often the best way to check the strength of the incoming connection from the modem.

We regularly update the site in an effort to keep this information up-to-date and accurate at all times. Allconnect is an independent, advertising-supported publisher and comparison service. Review registration fees and refund policies for U.S. test takers. Territories can register for international testing online. Get the latest information about test center closings.

Fast and safe

Our ultrafast speeds are 100Mbps and above. Speed assumes equipment is at optimum speed & capacity, device limitations apply. Speeds refer to download speeds unless stated otherwise. Maximum 5 compatible devices per account can watch TV, and only 2 devices can stream at any one time. New Virgin Media broadband customers subject to 24 month contract and set up fees may apply.

Comparing speed tests

Your first results should not be seen as a full measure of your broadband’s overall performance, so you might want to test it a few times at different points in the day to get a better overall reading. The best way to put speed tests to use is to run them on your phone or laptop in various rooms throughout your house. However, it also has banner ads that may slightly affect its test results on older devices. Ookla, on the other hand, has a strong reputation for consistency and access to deeper networking insights, and unlike Fast.com, it lets you specify which server you want to test against.

Latency is a measurement of how long it takes, in milliseconds, for your internet connection to send data to a remote server and receive a response. Though it doesn’t offer access to quite as many advanced metrics as other tests, Fast.com sets itself apart by simulating streaming traffic directly from Netflix servers. Device speeds vary, depending on how many devices you connect to Wi-Fi, how you use them, their age and type, and Wi-Fi signal strength. You can run the test through a cellular (mobile) network, a wired broadband connection, or your home Wi-Fi. A device speed test checks the speed between your smartphone, tablet, computer, or other device and the internet. Check the speed and performance of your connected devices with the speed test.

• M350 Fibre Broadband (average download speed at peak 362Mbps) and Weekend Chatter.
• This is typically the fastest way to connect to the internet.
• Fiber-optic internet delivers lightning-fast data to your home using pulses of light through ultra-thin glass cables, providing unmatched speed and reliability.
• We regularly update the site in an effort to keep this information up-to-date and accurate at all times.
• M500 Fibre Broadband (average download speed 516Mbps).
• Run a fast, accurate WiFi speed test for your home or small office network with your own private server.
• Compare fiber and broadband plans, check network coverage, and explore high-speed options for 4K streaming, gaming, and business use.

Our mission at Speedtest by Ookla® is to make the internet faster by providing data and insights on real-world internet speeds. Alternative broadband speeds available, prices vary depending on speed chosen If you cancel your service during your minimum term an early disconnection fee will apply. Browse this curated list of free internet speed tests and try one (or several) to test the high speed internet connection at your home. If you have a fast internet plan but are getting slow speed test results, you can determine if you’re overpaying for your service or if you simply need to troubleshoot your home Wi-Fi network.

How accurate is my speed test result?

As mentioned before, we’ve developed an entirely new evaluation methodology for internet speed tests in 2026. Most internet service providers offer an app that you can use to manage your account or pay your bill, and in a lot of cases, these apps will let you run a speed test, too. The best speed tests utilize robust server networks, so you’re never too far from an edge node, and they’ll also let you manually select a different server if you’d like.
