Servers in various locations that aren't affiliated with provider networks, which means more objective results.
Useful data on your internet speed by comparing it to your host and city average. That means you can determine if your high-speed internet plan is good compared to others in your area.
The interface isn't as clean as some competitors, and there are some pop-up ads.
You can get the best results by comparing multiple speed tests to determine your home's median or average outcome. Use the following tips and tricks to increase the accuracy of your network speed test:
Connect only the device you want to test. Having many devices running at once will slow down your test.
Having many devices running at once will slow down your test. If possible, do not test over a Wi-Fi connection. Home Wi-Fi speeds are more variable and will not give as accurate a measurement as a hard-wired device.
Home Wi-Fi speeds are more variable and will not give as accurate a measurement as a hard-wired device. Plug your device into your gateway with an Ethernet cable . An Ethernet connection gives the truest speed results.
. An Ethernet connection gives the truest speed results. For Wi-Fi devices, get close to your router . If an Ethernet connection is not an option, get as close to your wireless router as possible to get a more accurate result. A faulty or outdated router can cause slower speeds. If you notice a significant difference between a speed test with and without an Ethernet connection, it might be time to buy a new router.

Walking around with your device while performing a speed test will affect the outcome.
. Walking around with your device while performing a speed test will affect the outcome. Check your speed at different times of the day . For shared connections like cable and 5G internet, network congestion at busy times (evenings, weekends) will yield a slower speed. The time of day should not affect dedicated connections like fiber internet. Your internet service provider may throttle speeds during busy times, giving a speed test lower-than-normal results.

Comparison to your previous speed test results . Comparing your internet speed test to your previous results helps establish a baseline for what constitutes good internet performance in your area. It can also help you decide if the speed you're paying for matches your speed test results.

It can also help you decide if the speed you're paying for matches your speed test results. Consider the speed test server location. A speed test using a nearby server can accurately assess your internet speed under your typical conditions. However, occasionally internet traffic may be routed to other servers due to network congestion. As a result, some speed tests allow you to connect to more distant servers, enabling you to compare performance under various conditions.

HTML5, the newest interaction of Hypertext Markup Language (HTML), helps the site perform faster, a key attribute when measuring speed. 'Open source' means anyone can review the site's code to ensure the speed test is delivering accurate results.
If you notice your internet is slow, it's a good idea to run a speed test to see how it's performing. When you use a speed test, the results may seem like a foreign language. Here's a breakdown of key terms to know when interpreting the results of your speed test.
Download and upload speed
Definition: Measurements of how fast data is transferred to and from the server to your computer or other devices.
Measurements of how fast data is transferred to and from the server to your computer or other devices. How it's relevant in a speed test: This shows how fast your download and upload speeds are when you're doing online activities.
Ping test & latency
Definition: The gap of time between when you issue a command on your device and when the response arrives. A ping test measures latency in milliseconds (ms).
The gap of time between when you issue a command on your device and when the response arrives. A ping test measures latency in milliseconds (ms). How it's relevant in a speed test: An internet connection with a lot of latency will perform poorly and may result in lag for activities like streaming live TV.
Jitter
Definition: A measurement of abrupt changes in ping rate and latency.
A measurement of abrupt changes in ping rate and latency. How it's relevant in a speed test: A jitter rate of over 30 ms can poorly affect video and voice calls, which isn't great if you're working from home.
Packet loss
Definition: When some data doesn't reach its online destination.
When some data doesn't reach its online destination. How it's relevant in a speed test:If you have a high packet loss, then your internet signal is likely unreliable for data transfer. The result of packet loss can be lag or buffering.
Frequently asked questions
What is a good download and upload speed?
The internet speed you need will depend on your primary online activities. If you're mainly only online to browse, a good speed is 10–100 Mbps. If you're a live gamer or streamer, you'll typically 100–500 Mbps or more, depending on how many connected devices you have.
What does ping mean?
Ping is actually an acronym for Packet Inter-Network Groper. Ping is a computer command that verifies an IP address. It is used to diagnose connectivity issues and test data transfer rates. According to HP, a ping rate of less than 100 milliseconds (ms) is good for most online activities, but 20 ms or less is best for gaming.
What does latency mean?
Latency is the time it takes data to travel from your computer to its destination, measured in milliseconds. The ping test measures latency, and thhat's why the terms are often used interchangeably.
What does jitter mean?
Jitter measures the delay between when your computer sends a signal and when your network receives it. Jitter should typically be two milliseconds (ms) or less. However, some internet connections will have a higher jitter rate, like satellite internet.
Why is my internet slow if my speed test is fast?
If you find you get good speed test results but your device is still running slow, it might just be that the device is old or outdated. If your smartphone is overloaded with apps, this might also result in a slow connection.
