A Simple, Free Speed Test
This tool helps you quickly diagnose connection issues, check whether your home network is ready for live sessions, or compare Wi‑Fi versus cable performance. For the most accurate results, pause downloads, streaming, cloud backups, and software updates while you test. Security tools (like VPNs or strict firewalls) can also affect results—if you temporarily disable anything, remember to turn it back on immediately after testing.
How the Measurement Works
During the test, our server sends data to your device and measures how long it takes to receive and return packets. The tool uses multiple packet sizes to produce a more reliable measurement. Because the test uses available bandwidth, try not to browse, download files, or run video calls at the same time.
What the Results Mean
This speed test measures four key parts of your connection: download, upload, ping (latency), and jitter. Together, they explain both “how fast” and “how stable” your internet is—especially important for live learning.
-
Download Speed: How quickly data reaches your device from the internet (Mbps). Strong download speed helps with streaming lesson content, downloading files, and smooth browsing during classes.
-
Upload Speed: How quickly data leaves your device to the internet (Mbps). Upload matters for video calls, screen sharing, sending large files, and pushing code to GitHub—common in online bootcamps.
-
Ping (Latency): How long it takes for a signal to travel from your device to a server and back (ms). Lower ping usually means more responsive calls and fewer delays in real-time collaboration.
-
Jitter: How consistent the connection is (variation in packet timing). Low jitter is important for stable video/audio and fewer drops or glitches during live sessions.
Run a Few Tests for a Clearer Picture
One test is a snapshot—not the whole story. Results can change based on time of day, Wi‑Fi interference, device performance, and network congestion. For a more accurate view, run 2–3 tests at different times (for example morning, afternoon, and evening) and compare the averages.
If you’re learning online from Greece, a reliable connection helps you get the most out of live classes, pair work, and portfolio projects. Knowing your speeds makes it easier to troubleshoot and improve your setup—whether that means moving closer to the router, switching to Ethernet, or checking with your provider.
