Checking test service
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.

Connection Comparison guide
Compare two locally saved speed tests side by side.
Open Connection ComparisonWhat you need
- At least two saved speed-test results
- Optional labels and notes
How to use it
- 1Run and save comparable speed tests.
- 2Open Connection Comparison.
- 3Select two results.
- 4Review differences in speed, latency and confidence.
Understanding the results
- Compare tests performed under similar device, location and connection conditions.
Recommended next actions
- Repeat each connection under controlled conditions.
Common problems
- Results may be absent after browser storage is cleared or on another device.
Privacy and security
- Saved comparisons stay in this browser unless exported.
Worked example
- Scenario
- Comparing Wi-Fi and Ethernet
- Example input
- One labelled Wi-Fi result and one Ethernet result
- How to read it
- The side-by-side view shows whether throughput and loaded latency changed under the two connection methods.
Limitations
- Differences do not prove either service is faulty when test conditions differ.
Do not rely on one result for a production, security, safety, purchasing or contractual decision. Verify important findings independently.
