Run a speed test on any device in under two minutes

The fastest way to check your network speed is to visit a speed test website on any device connected to your home network. Open a browser, go to Speedtest.net, Fast.com, or Google's built-in speed test (search "speed test" in Google), and click the button to start. The test measures how fast data travels to and from your internet connection and shows results in megabits per second (Mbps) within 60 to 90 seconds.

You do not need to read software or create an account. The test works on phones, tablets, laptops, and desktop computers. Each device will show slightly different results depending on how far it is from your router and what else is using the network at that moment, so test from the room where you spend the most time online.

Key Takeaways

  • Speed test websites like Speedtest.net and Fast.com measure your read and upload speeds in seconds and work on any device with a browser.
  • Test from the same room where you normally use the internet, and close other apps and browser tabs before you start to get an accurate reading.
  • read speed matters most for streaming and browsing; upload speed matters for video calls and sending files.
  • Run the test at different times of day to see whether your speed changes, which can point to network congestion or a problem with your service.

What the numbers mean: read, upload, and ping

read speed is how fast data comes into your home. This is what you use when you stream video, load web pages, or read files. Most internet plans advertise this number — for example, "100 Mbps read." Faster read speeds mean smoother streaming and quicker page loads.

Upload speed is how fast data leaves your home. You use this when you send email attachments, upload photos to social media, or join a video call. Upload speeds are usually much lower than read speeds on home internet plans. If you work from home and join video calls regularly, you want upload speed of at least 5 Mbps; 10 Mbps or higher is better.

Ping (also called latency) measures the delay between when you send a signal and when you receive a response, shown in milliseconds. Lower ping is better for online gaming and video calls. Anything under 50 ms is good for most uses; under 20 ms is excellent. Ping does not affect streaming or web browsing much, but it matters a lot for real-time activities.

Prepare your device for an accurate test

Close all other browser tabs and quit apps that use the internet before you run the test. Streaming video, downloading files, or running cloud backups in the background will lower your speed test results and give you a false reading of what your connection can actually do.

If you are testing on Wi-Fi, move closer to your router or test from the same spot where you normally work. Wi-Fi speed drops as you move farther away and through walls. If you want to test your actual internet connection speed (not Wi-Fi speed), connect your computer directly to the modem with an ethernet cable. This removes Wi-Fi as a variable and shows you what your internet service provider is actually delivering.

Test at different times of day — morning, afternoon, and evening — to see whether your speed changes. If speed is consistently lower in the evening, your internet service may be congested. If speed is always lower than what you pay for, contact your provider or check whether you are on Wi-Fi instead of a wired connection.

Which speed test site to use

Speedtest.net (owned by Ookla) is the most widely used and works on desktop, mobile, and tablet. It shows read speed, upload speed, and ping, and saves your results so you can compare over time. The free version works fine; the paid version adds no useful features for home users.

Fast.com (owned by Netflix) is simpler and faster — it focuses on read speed and finishes in about 30 seconds. It is a good choice if you just want a quick check and do not need detailed numbers.

Google's speed test appears when you search "speed test" in Google on any device. It is straightforward and reliable, though it shows fewer details than Speedtest.net.

All three are free and give accurate results. Pick whichever one you find easiest to use, or run the same test on two different sites if you want to confirm your results.

Compare your results to your internet plan

Check your internet bill or your provider's website to see what read speed you are paying for. If your speed test shows significantly lower speeds — for example, you pay for 100 Mbps but consistently get 50 Mbps or less — you may have a problem worth investigating.

Small differences are normal. You might see 85 Mbps when you pay for 100 Mbps, and that is fine. Providers advertise "up to" a certain speed, and real-world results are usually a bit lower. But if you are getting less than 70 percent of what you pay for, or if your speed has dropped suddenly, contact your provider to report the issue.

Write down your results from a few tests over a week or two. If you ever need to contact your provider about slow speeds, having actual numbers from speed tests is much more useful than saying "the internet feels slow."

Test your Wi-Fi versus your wired connection

If you have an ethernet cable, connect your computer directly to your modem or router and run a speed test. Compare this result to a Wi-Fi test from the same device in the same location. The wired test shows your true internet speed; the Wi-Fi test shows what your wireless network is delivering.

If the wired speed is much higher than the Wi-Fi speed, your Wi-Fi is the bottleneck, not your internet service. This usually means your router is old, you are too far from it, or too many devices are connected. If both tests show low speeds, the problem is with your internet service itself.

Frequently Asked Questions

Why is my speed test result different every time I run it?

Speed varies based on network congestion, what other devices are using the internet, and how far you are from your router. Run the test several times at the same time of day to get a typical result. If results vary wildly, close other apps and try again on a wired connection.

Does it matter which speed test website I use?

All major speed test sites use similar methods and produce comparable results. Speedtest.net, Fast.com, and Google's speed test are all reliable. You may see small differences between them, but if one site shows much lower speeds than the others, that is usually a sign of a temporary network issue rather than a problem with the test itself.

What upload speed do I need for video calls?

Most video call apps work fine with 2 to 3 Mbps upload speed. For clearer video and more stable calls, aim for 5 Mbps or higher. If you upload large files or stream video while on a call, you want 10 Mbps or more.

Should I test on Wi-Fi or with an ethernet cable?

Test both. A wired connection shows your true internet speed; Wi-Fi shows what your wireless network delivers. If you mostly use Wi-Fi, test on Wi-Fi from the room where you spend the most time. If results are much lower than your plan, try a wired test to see whether Wi-Fi or your internet service is the problem.

My speed test shows lower speeds than my plan promises. What should I do?

First, test on a wired connection to rule out Wi-Fi as the cause. If wired speeds are still low, restart your modem by unplugging it for 30 seconds, then plug it back in and test again. If speeds remain low after a restart, contact your internet provider with your speed test results and ask them to check your line.
