Which floor was the Wi‑Fi signal observed to drop to almost zero?

• A. Floor 41
• B. Floor 35
• C. Floor 30
• D. Floor 40

Answer: (A)

Wi‑Fi signal strength decreases as distance increases and as obstacles between the access point and the device multiply. In a multi-floor building, each extra floor adds more material to penetrate, so the strongest coverage is usually closest to the AP and weakens toward the higher or farther floors. In this scenario, the measurement on the top floor shows the signal dropping to nearly zero, which clearly indicates a coverage gap on that level. That near-zero reading on the top floor stands out against the other floors, which still have usable signal, making it the best choice. This situation often happens due to distance, thick building materials, and potential shielding like elevator shafts or concrete barriers, all of which hinder propagation to that floor.
