How this WiFi speed test works

When you press GO, WiFi Speed Insight finds a nearby test server and runs four measurements in a row.

  1. Ping

    A dozen tiny requests time the round trip to the server. Lower is better. Learn more in ping and jitter explained.

  2. Jitter

    How much those round-trip times vary. Steady is better for calls and games.

  3. Download

    Several parallel downloads fill your connection for 8 seconds. The result is in megabits per second; see what Mbps means.

  4. Upload

    The same in the other direction, which matters for video calls and posting. For a deeper look use the upload speed test.

While the download runs, WiFi Speed Insight also pings in the background. If ping jumps a lot under load, your router is suffering from bufferbloat. The bufferbloat test grades it from A+ to F.

Speeds over WiFi are almost always lower than the plan you pay for. If yours looks slow, work through why your WiFi is slow and how to fix it.

Browsers protect your privacy, so some WiFi details are only available to a phone app or your router. Here’s where to find them instead, and how WiFi Speed Insight measures.

WiFi speed test questions

Short answers to what people ask most. More in the WiFi guides.

Why is my result different from other speed tests?
Every test uses a different server and method, and WiFi, other devices and background downloads all change the result. Run a few tests and compare the average.
What is a good internet speed?
For one person, 25 Mbps download is enough for HD streaming and calls; a busy household is happier with 100 Mbps or more. See what is a good internet speed for a full breakdown by activity.
Does the test use a lot of data?
Yes. A full test can use roughly 100 MB to a few hundred megabytes on a fast connection. On a limited mobile plan, use it sparingly.
What do ping and jitter mean?
Ping is how long a message takes to reach the server and come back; jitter is how much that time varies. Both matter for gaming and video calls. Our guide on ping and jitter explains what good numbers look like.
Is the speed test free and private?
Yes. There’s no signup, and your results are saved only in your own browser. Read the privacy policy for details.
