Summary
Learn the best spots to place your Wi-Fi router to eliminate dead zones. Tips on height, obstacles, and how to handle concrete walls in Bangladesh.

Summary

The best place for a router is a central, elevated, and open location within your home. Wi-Fi signals travel outward and downward; placing the router in a corner, inside a cupboard, or on the floor will significantly reduce its range and performance. For most Bangladeshi flats, the central dining or living area is the ideal spot.

Overview

Think of your router like a lightbulb. If you put a lightbulb in the corner of a room, it only lights up half the space. If you put it inside a box, the light is dim everywhere. Wi-Fi works the same way. Every wall, door, and piece of furniture acts as a “shadow” that blocks the signal.

Technical Deep-Dive

Line of Sight and Obstacles

Wi-Fi uses radio waves. While they can pass through objects, they lose energy every time they do.

  • Reflection: Metal surfaces (refrigerators, mirrors, filing cabinets) reflect Wi-Fi signals, causing interference.
  • Absorption: Materials like water (fish tanks), wood, and drywall absorb some signal.
  • Refraction: The signal can bend slightly around corners, but this weakens it significantly.

The “High Ground” Advantage

Routers are designed to broadcast signals slightly downward. Placing your router on a high shelf or mounting it on a wall at eye level (or higher) helps the signal clear furniture obstacles and reach further.

Antenna Orientation

If your router has external antennas:

  • For a single-floor flat: Point them straight up (vertical).
  • For a multi-floor house: Tilt one antenna horizontally to help the signal travel through the ceiling/floor.

Bangladesh Context

In Bangladesh, the biggest enemy of Wi-Fi is the Concrete Wall.

  1. The 10-inch Wall: Most exterior and structural walls in BD are 10 inches of solid brick/concrete. A 5GHz signal will almost never pass through a 10-inch wall with usable speed.
  2. The “Hidden Router” Problem: Many people hide their router inside a wooden “TV Cabinet” or a “Shoe Rack” for aesthetics. In a concrete home, this is a recipe for dead zones.
  3. The Kitchen/Bathroom Block: Avoid placing the router near the kitchen (microwave interference) or bathrooms (water in pipes and tiled walls reflect signals).

Pro Tip for BD Homes: If your ISP’s “ONU” (fiber box) is in a corner of the house, don’t put the router there. Run a long Cat6 Ethernet cable to the center of the house and place the router there.

FAQ

  • Q: Can I put my router in a cupboard to hide the wires?
    • A: No. Even a thin wooden door can reduce signal strength by 10-20%. Metal cabinets are even worse and can kill the signal entirely.
  • Q: Does putting the router near a window help?
    • A: No. In fact, it’s worse. You are sending half of your signal outside the house where it is wasted. Keep it away from exterior windows to focus the signal indoors.
  • Q: I live in a large flat; will one router be enough?
    • A: In a typical 1500+ sq ft Bangladeshi flat with multiple concrete walls, a single router—no matter how expensive—will likely have dead zones. Consider a Mesh Wi-Fi system or an Access Point connected via cable.
