Question 1

What is a good internet speed?

Accepted Answer

For HD streaming and video calls, 25 Mbps download is plenty. For 4K streaming, gaming, or multiple users, aim for 100 Mbps or more. Fibre connections typically deliver 300–1000 Mbps.

Question 2

Why does my speed vary between tests?

Accepted Answer

Network conditions change constantly — Wi-Fi interference, other devices on your network, time of day, and the server you test against all affect results. Run several tests for an accurate picture.

Question 3

What do download, upload, ping and jitter mean?

Accepted Answer

Download is how fast data reaches you (streaming, browsing). Upload is how fast data leaves you (video calls, file sharing). Ping is round-trip latency. Jitter is variation in ping over time — important for real-time apps like gaming and calls.

Question 4

Should I test over Wi-Fi or Ethernet?

Accepted Answer

Ethernet gives you the truest read of your ISP plan. If Wi-Fi speeds are much lower than Ethernet, the bottleneck is your router or interference — not your ISP.

Question 5

Is the test free? Do I need to install anything?

Accepted Answer

Completely free, no install required, no signup. Tests run directly in your browser against the nearest Cloudflare edge server.
