How to read the results
- Download (Mbps): how fast data reaches you. Streaming 4K video needs about 25 Mbps per stream; video calls need 3–5 Mbps.
- Upload (Mbps): how fast you send data, which matters for video calls, cloud backup and live streaming.
- Ping (ms): the round trip to the server. Under 30 ms feels instant; over 100 ms is noticeable in games and calls.
- Jitter (ms): how much ping varies. Low jitter (under 10 ms) keeps calls and games smooth.
Why results differ from your plan
Wi-Fi is usually the bottleneck: distance, walls and older routers cut speed sharply. For a fair test use a cable, close other apps and downloads, and run the test twice. Results also vary with the time of day, the device, and the server's distance. A plan's "up to" speed is a maximum, not a guarantee.
