Question 1

What does an internet speed test measure?

Accepted Answer

It measures download throughput, upload throughput, ping and jitter from your browser. These values show both capacity and responsiveness of your current connection.

Question 2

Why is my speed lower than my ISP plan?

Accepted Answer

Advertised speeds are usually best-case plan speeds. Wi-Fi distance, router quality, congestion, VPNs, old devices and background downloads can all reduce the result.

Question 3

Should I test on Wi-Fi or Ethernet?

Accepted Answer

Use Ethernet when you want to check the internet line itself. Use Wi-Fi when you want to know what your real device experience feels like.

Question 4

What is more important, download or upload?

Accepted Answer

Download matters most for browsing and streaming. Upload matters for video calls, cloud backups, live streaming and sending large files.

Question 5

Why do speed tests change each time?

Accepted Answer

Internet routes, local Wi-Fi conditions and background device activity change constantly, so small differences between tests are normal.
