How this check works
This is a rule-based triage aid, not a network scanner. A problem-room result below half of the router-side reading triggers coverage advice. That 50% threshold is an editorial heuristic, not an Ofcom standard. Results vary with device, time and load. Wired speed below a contract minimum triggers a repeat-test and provider-support route, not an automatic switching recommendation. Outages and single-device problems are handled before shopping advice.
