Weak Wi‑Fi coverage in one area, with better signal across the hall, is most likely caused by what?

• A. The AP is a remote AP
• B. The AP uses a directional antenna
• C. The AP is outdoor
• D. The AP is configured in Mesh mode

Answer: (B)

Antenna radiation patterns shape how wireless coverage spreads. A directional antenna concentrates energy in a specific direction, creating a strong beam toward that area and weaker signal elsewhere. If one area has weak coverage while the area across the hall has good signal, it most likely means the AP’s antenna is aimed toward the hall, delivering a strong signal there while the nearby space falls outside the main beam (or sits in a side lobe or null). In other words, the AP is radiating most of its power in the opposite direction to the weak spot. To address this, check the AP’s antenna type and orientation. If you need more uniform coverage, you could rotate or reorient toward the weaker area or replace with an omnidirectional antenna to spread power more evenly. Other scenarios like an outdoor AP or Mesh mode don’t as cleanly explain this one-direction strong/one-direction weak pattern.
