Easy, free internet speed test
Use this tool to diagnose network issues, optimise your setup, or simply confirm your connection performance before a live session. For the most accurate results, close background downloads and streaming apps before you start. If security software heavily scans network traffic, it may affect results—only pause it if you understand the impact, and re-enable it immediately after the test. Then click “Start” to run the test.
How the measurement works
To measure speed, our server sends data packets to your device and measures how long it takes to download and upload them. The test uses multiple packet sizes so results are more stable. During the test, avoid other activities that consume bandwidth (downloads, video streaming, large file sync, or email attachments), as the tool will use your available connection capacity.
What the results mean
This tool measures four essential components of your internet connection: download speed, upload speed, ping (latency), and jitter.
-
Download speed: How fast data travels from the internet to your device, usually shown in Mbps. Higher download speeds help with streaming, browsing, and downloading course materials.
-
Upload speed: How fast data travels from your device to the internet, usually shown in Mbps. Higher upload speeds help with video calls, screen sharing, and uploading projects or files.
-
Ping (latency): How long it takes (in ms) for a data packet to travel from your device to a server and back. Lower ping is better for real-time activities like live classes, video calls, and online collaboration.
-
Jitter: The variation in packet timing. Lower jitter means a more consistent connection, which is especially important for video calls, VoIP, and live learning sessions.
Run multiple tests for more reliable results
A single speed test can be affected by temporary factors such as Wi‑Fi interference, server load, or network congestion. For a clearer picture, run several tests at different times of day and compare the results. Averaging multiple tests can help you estimate your typical download and upload speeds more accurately.
