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.
Ping
A dozen tiny requests time the round trip to the server. Lower is better. Learn more in ping and jitter explained.
Jitter
How much those round-trip times vary. Steady is better for calls and games.
Download
Several parallel downloads fill your connection for 8 seconds. The result is in megabits per second; see what Mbps means.
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.
