Internet Speed Test

When you press GO, the test runs three phases. First it measures ping and jitter with a series of small requests, discarding the initial samples so connection setup doesn't inflate the numbers. Then it opens four parallel download streams for ten seconds, sizing each request to your connection so slow and fast lines are both measured fairly. Finally it pushes data upstream the same way to measure upload.

Testing against the nearest CDN edge server means the result reflects your connection — not the distance to some far-away test server. For the most accurate reading, close bandwidth-heavy apps (video calls, downloads, streaming) and test a few times at different hours.

Each number answers a different question about your connection:

• Download (Mbps) — how fast data reaches you. Drives streaming quality, page loads, and download times.
• Upload (Mbps) — how fast you send data. Matters for video calls, cloud backups, and posting large files.
• Ping (ms) — round-trip delay to the server. Under 20 ms is excellent; over 100 ms feels laggy in games and calls.
• Jitter (ms) — how much your ping varies. High jitter causes choppy calls even when average ping looks fine.

A speed test measures the whole path from your device to the internet — which includes your WiFi link. If a wired (ethernet) test hits your plan speed but WiFi tests come in far lower, your internet is fine and your WiFi is the bottleneck: think router placement, band selection, or aging hardware.

That distinction decides whether the fix is calling your ISP or moving your router. Test both ways before blaming either.
