Investigate the actual place where a device is used, not just the nearest doorway.
Define what “dead zone” means
A room may be called a dead zone because the network disappears, a connection drops, or an application becomes unusable. Ask which of those happens and on which device. If possible, reproduce the symptom before changing the network.
Mark the affected work position on the floor. A phone held at a doorway may have a different experience from a laptop at a desk inside the room. The complaint should guide the measurement location.
Build a short comparison route
Start at a position where the service usually works, move through the transition to the affected room, and finish at the actual trouble spot. Capture deliberate readings along that route with the same device. Repeat a suspect point rather than immediately widening the survey to the whole building.
Check the BSSID and band of the observations. A changing set of visible radios can help frame the next question, but a nearby scan by itself does not prove which AP an application used during a failure.
Avoid an instant hardware conclusion
Weak signal in a room does not automatically justify buying another access point. First confirm the installed AP locations and any obvious changes to the environment or configuration. Keep a record of what you know versus what you suspect.
If signal appears adequate but the problem persists, add suitable application or connection tests. A coverage survey should narrow the investigation, not force every symptom into a coverage explanation.
Test the smallest useful change
When an authorized administrator makes a change, repeat the same route and the affected work position. Keep a reference point elsewhere so you can see whether the change helped one area while altering another.
Export the before-and-after observations and state any differences in device or conditions. In Wi-Fi Master Planner, preserve the earlier survey rather than replacing its readings with the new visit. Historical evidence makes the decision easier to explain.
Take it into the field
- Describe the failure before calling it a coverage problem.
- Measure the real work position and a reference point.
- Check network identifiers and bands.
- Repeat the same route after an authorized change.
