Internet Speed Test
Measure ping, jitter, download and upload speed with a sustained browser-based network test.
How to use this test
Start the test from a quiet connection and keep the tab open while ping, download and upload samples run. Stop cancels any active transfer.
How the measurement works
The test automatically selects a nearby measurement server, exchanges temporary test data for sustained download and upload measurements, and samples connection responsiveness while the test runs. The live gauge follows the measured throughput in real time.
How to interpret results
Ping and jitter describe responsiveness, download affects streaming and downloads, and upload affects calls, backups and live streaming. WiFi and VPNs can change all three.
Troubleshooting tips
Pause cloud sync, VPNs and downloads, move closer to the router and repeat at a different time if results look much lower than your internet plan.

Common speed test questions
Why do different speed-test websites give different results?
Each service measures a different network path to different servers and may use different connection counts and durations. Wi-Fi conditions and congestion also change moment to moment, so compare several runs under similar conditions.

Ethernet usually removes wireless interference and signal-strength variation, making it better for checking the fixed-line connection itself. Wi-Fi testing is still useful when you want to measure the experience of the device where it is normally used.
Read full answer →What do download, upload, latency and jitter mean?
Download measures data received per second, upload measures data sent per second, latency measures round-trip delay, and jitter describes how much that delay varies between samples. Different activities care about different combinations of these metrics.
Read full answer →Why can this result differ from another speed-test website?
Speed tests measure the path between your device and their own test servers. Server location, peering, Wi-Fi conditions, congestion, connection count and test duration can all change the result, so compare several runs under the same conditions.
