Frequently asked questions

Start with a short answer: broadband speed tests are most useful when you run them consistently, compare different times of day, and use the results to make practical decisions.

Why does my speed test result change?

Broadband speed test results can change because Wi-Fi signal quality, router placement, household usage, device capability and peak-time network demand vary throughout the day.

Is one speed test enough?

No. Run at least two to three tests at different times, especially during evening busy hours, to build a realistic performance baseline for your line.

What is a good latency value for home broadband?

As practical guidance, under 20 ms is excellent, 20 to 40 ms is good for most households, 40 to 70 ms is usable, and above 70 ms is more likely to feel delayed in real-time activities.

What is a good jitter value?

Lower jitter is better because it indicates a steadier connection. Under 10 ms is typically very stable, while higher jitter can affect call quality and gaming responsiveness.

Why do wired and Wi-Fi speed tests differ?

Wi-Fi can be affected by distance, walls, interference and competing devices. A wired Ethernet test usually gives a cleaner view of line performance.

What should I do if my speed drops in the evening?

Compare off-peak and peak-time tests first. Then check home setup factors and contact your provider if the service is consistently below expected levels.

Do VPNs and background apps affect speed test results?

Yes. VPN routing, cloud backups, app updates and streaming in the background can reduce measured throughput and increase latency during a test.

Does Broadband Speed Test store my test data?

Broadband Speed Test does not store individual speed test results on its own servers. See the privacy policy and cookie policy for details on third-party requests and analytics consent.
