Your test

Download, upload, ping and jitter between your device and the Lodestar server. Results depend on your connection, device and the route to our server. Wi-Fi, mobile signal and other network activity can affect the measurement.

How it works

The test checks latency, then download and upload. It uses 32 parallel download and upload streams and takes around 30 seconds. Tests can use hundreds of MB of data. You can stop at any time.

Your history

Your last 20 completed tests are saved in this browser. Use History to view or clear them. There are no accounts, ads, analytics or ISP lookups. Generated upload data is discarded, and results are not stored on the server. The gateway processes your connection address to respond.

Android app

LSN Speedtest uses this public server and saves results on your phone. The Connection section shows available mobile or Wi-Fi details. Stress tests can repeat for 10, 30 or 60 minutes and continue while the phone is locked, with a Stop notification. Android 8.0 or later is required.
