Tool guide limitationsGuides explain the intended workflow but cannot cover every device, provider or operating condition.

Interfaces and external services can change. Follow the current on-screen controls, check dates and vendor documentation, and verify important results independently before acting on them.

Important: Do not rely on this result alone for purchasing, configuration, security, safety, compliance, contractual or fault-diagnosis decisions. Results can be incomplete, delayed, misleading or wrong. Verify important findings with the relevant provider, manufacturer documentation and an appropriate independent test or qualified professional.

Internet Speed Test guide

Measure browser download speed, upload speed, latency and loaded connection behaviour.

Open Internet Speed Test

What you need

  • Number of test runs
  • Optional expected package speed and connection label

How to use it

  1. 1Choose the number of runs.
  2. 2Close bandwidth-heavy applications.
  3. 3Start the test and keep the tab open.
  4. 4Review or export the completed results.

Understanding the results

  • Compare the average with individual runs and the expected package speed.
  • Use confidence and loaded-latency indicators before drawing conclusions.

Recommended next actions

  • Repeat on Ethernet where practical, then run Connection Quality or Full Diagnostics.

Common problems

  • Wi-Fi, VPNs, device load and background traffic can lower the result.
  • A single result may reflect temporary congestion.

Privacy and security

  • Public IP and browser details may be shown; exported data should be reviewed before sharing.

Worked example

Scenario
Checking a 100 Mbps broadband package
Example input
3 runs; expected download 100 Mbps
How to read it
An 88 Mbps average with consistent runs suggests usable performance, but does not prove the provider line rate.

Limitations

  • This is a browser estimate, not a certified line-speed measurement.

Do not rely on one result for a production, security, safety, purchasing or contractual decision. Verify important findings independently.
