A fast, free speed test
This tool is useful for troubleshooting connection issues, optimising your setup for remote learning, or simply understanding your internet performance. For the most accurate result, close bandwidth-heavy apps (streaming, downloads, cloud sync). If your security software runs intensive network scanning, you may pause it briefly and re-enable it immediately after the test. When you’re ready, click “Start” and let the test run uninterrupted.
How the measurement works
During the test, our server sends data packets to your device and measures how long it takes to receive them (download) and send data back (upload). Multiple packet sizes are used to improve accuracy. To avoid skewed results, don’t download files, open new websites, or run video calls while the test is running—this test will use a large share of your available bandwidth.
What the results mean
This tool measures the key components of your connection: download speed, upload speed, ping (latency), and jitter.
-
Download speed: How fast data comes from the internet to your device (Mbps). Higher download speeds improve streaming, browsing, and downloading course materials.
-
Upload speed: How fast your device sends data to the internet (Mbps). Upload is critical for video calls, sharing files, screen sharing, and submitting projects.
-
Ping (latency): How long it takes data to travel to a server and back (ms). Lower latency helps live sessions feel more responsive—especially during Q&A, screen sharing, and real-time collaboration.
-
Jitter: How much your latency varies over time. Low jitter is important for stable video calls and live learning: it reduces stuttering, audio dropouts, and disconnections.
Run a few tests for a more reliable picture
One test is a snapshot. Results can change depending on the time of day, Wi‑Fi conditions, and how busy your network is. For a more accurate view, run several tests at different times (morning, afternoon, evening) and compare the averages.
If you’re learning online from France, a stable connection matters as much as a fast one. If your results vary widely, try switching to Ethernet, moving closer to your router, or pausing other devices on your network during live classes.
