Measure internet speed more reliably
Control device, Wi-Fi and background traffic before using a speed result to diagnose a connection.

The answer in 30 seconds
A speed test measures a path from one device to a test server at one moment. It can be limited by the device, browser, Wi-Fi, local traffic or the test server as well as by the access line.
Repeat tests under comparable conditions, ideally including an Ethernet test near the router, and record time, device, connection type and upload, download and latency results.
Examples to adapt
Compare near-router and room tests before blaming the internet subscription.
Test a wired device if possible and note whether background downloads are active.
Record interruptions and latency as well as headline download speed.
Follow the method
- 1Prepare a device
Use an updated device capable of the speeds you expect and pause large transfers.
- 2Test near the router
If possible, connect by suitable Ethernet cable and record the conditions.
- 3Repeat over time
Use the same method at different times to see whether the problem persists.
- 4Compare carefully
Separate line performance from Wi-Fi coverage and device limitations before contacting the provider.
A checklist to keep
Use these checks to record what you found. The grid supports a decision; it does not make one for you.
| Check | What to examine | Action |
|---|---|---|
| Device | Can it handle the expected speed? | Check |
| Connection | Ethernet or Wi-Fi? | Record |
| Traffic | Were large transfers paused? | Control |
| Result | Download, upload and latency? | Note |
| Repeat | Does the pattern persist? | Compare |

What to check
A single test is not a diagnosis.
Older hardware and cables can limit measured speed.
Changing test server or Wi-Fi band can change the result.
Common questions
Why is Wi-Fi slower than Ethernet?
Distance, interference, walls and device capability can constrain the wireless link.
What should I send to a provider?
Give several dated results with device and wired or wireless conditions, plus the symptoms you observe.
