The quality of a wireless connection in an apartment often depends not on the power of the equipment, but on where exactly it is installed. Many users make the mistake of hiding Wi-Fi router into a TV niche or on a cabinet shelf, not realizing that a physical obstacle can block up to 30% of the useful signal. Choosing the right location can increase internet speed without purchasing expensive amplifiers.
Radio waves propagate from their source according to certain laws of physics, encountering resistance in the form of walls, furniture, and household appliances. If you notice that video loads slowly in distant rooms or the connection drops, the problem may lie in this area. room geometry and access point location. In this article, we'll discuss how to find the ideal location for equipment installation.
It's important to understand that there's no one-size-fits-all solution for every apartment, as layouts and wall materials vary. However, there are basic principles of radio wave propagation that, if ignored, can render even the most powerful equipment useless. Let's look at the key factors affecting the stability of your home network.
The center of the room is the key rule of geometry
The most common mistake is installing the router where the internet cable from the provider enters. This is usually the front door or a corner of the apartment, which creates a situation where the signal spreads outward rather than inward. The ideal scenario is central location devices so that the distance to all rooms is approximately the same. This minimizes signal loss when passing through thick walls.
If moving the cable to the center of the apartment isn't feasible, try to find a compromise location. For example, a hallway connecting living areas is often better than a blind corner near the front door. In such cases, it's worth considering running a long patch cord or using technology. PoE to place the access point in a more advantageous position.
Keep in mind that walls made of concrete or brick with reinforcement act as a shield, significantly weakening radio waves. The fewer obstacles between the router and your device, the better the signal will be. data transfer rateTherefore, an open space in the center of an apartment always wins over a closed corner.
Installation height and horizontal positioning
The physics of radio waves dictates its own rules: cold air is heavier than warm air, but radio signals propagate better in open space at altitude. Raise your router as high as possible, ideally at ground level. 1.5–2 meters from the floor. This allows the signal to bend around furniture and other obstacles that may be at ground level.
Placing the device on the floor is the worst option imaginable. The signal is then blocked by furniture, carpets, and even people walking by. Furthermore, more dust accumulates on the floor, which can lead to overheating of the electronics and reduced performance of the router's processor.
It's also important to consider the antenna orientation. If your device has external antennas, position them vertically for better horizontal coverage. In two-story houses, one antenna can be left vertical and the other positioned horizontally to improve coverage between floors.
Influence of wall and ceiling materials
Different materials affect the transmission of 2.4 and 5 GHz radio signals differently. Knowing the materials in your home can help you predict "dead zones." For example, drywall absorbs minimally, while concrete walls with metal reinforcement create a significant barrier.
Particular attention should be paid to mirrors and glass. Large mirrored surfaces or tinted window panes can reflect the signal, creating interference or directing it in the wrong direction (for example, toward the street). Metal structures in the walls also act as Faraday screen, completely blocking the connection.
| Barrier material | Impact on signal | Recommendation |
|---|---|---|
| Drywall | Minimum | Can be placed behind a wall |
| Tree | Weak | Acceptable but not desirable |
| Brick | Medium/Strong | Avoid direct obstacles |
| Concrete with reinforcement | Critical | A repeater or mesh is required. |
| Mirror/Metal | Reflection/Blocking | Do not put opposite |
If your router is behind a thick concrete wall, you won't be able to get stable performance in the next room. In such cases, it's best to run a cable to the next room and install a second access point there, or use Mesh system.
Why is 5 GHz worse at passing through walls?
The 5 GHz band offers higher speeds but has a shorter wavelength. This makes it more susceptible to obstacles. The 2.4 GHz signal is better at bypassing obstacles but operates slower and in noisier environments.
Household appliances as a source of interference
Modern apartments are filled with devices that generate electromagnetic fields that interfere with Wi-Fi. Microwave ovens operate at 2.4 GHz, creating powerful interference during cooking. Placing your router near the kitchen or on top of the refrigerator is a bad idea.
Other sources of interference include cordless phones, baby monitors, Bluetooth speakers, and even Christmas lights with a controller. Aquariums are also a serious obstacle, as water absorbs radio waves well. Electromagnetic interference can reduce the actual connection speed several times.
⚠️ Caution: Avoid placing the router near powerful heat or radiation sources, such as radiators, microwaves, or high-power audio systems. This may not only result in signal loss but also reduce the lifespan of the device.Check the router's surroundings. If there's a monitor, PC, or other electronic device nearby, try moving the router at least 50-70 cm away. Sometimes, simply moving the device half a meter away from a microwave can work wonders.
Antennas: vertical or horizontal?
Many users mistakenly believe that antennas should be pointed directly at the device consuming the internet (laptop or phone). In fact, a router's antenna coverage area is shaped like a donut (a toroidal radiation pattern), with the signal perpendicular to the antenna axis.
If the antenna is vertical, the signal propagates horizontally, covering the entire floor. Placing the router on its side or tilting the antenna will change the coverage geometry, which can create "holes" in the reception area. For a standard apartment, vertical antenna placement is optimal.
In the case of a multi-story building (cottage), one of the antennas can be positioned horizontally to penetrate the ceiling to the upper or lower floor. However, within a single floor, vertical orientation remains the only acceptable standard for ensuring coverage. uniform coverage.
Concealed installation: pros and cons
Aesthetics often dictate hiding the router and its wires, but this can be fatal for the equipment. Closing the device in a niche, behind a curtain, or in a closed cabinet drawer leads to overheating and signal shielding. The router requires adequate airflow to cool the processor and radio module.
If you do decide to hide your router, use furniture with open shelves or provide ventilation. Metal panels in wardrobes completely block Wi-Fi. Plastic and wood transmit the signal better, but still introduce attenuation.

Can I place my router horizontally on a shelf?
Yes, if the antennas are removable or rotatable, they still need to be pointed vertically upward. If the antennas are built-in and located inside the case, follow the manufacturer's instructions, but horizontal orientation is generally suitable for desktop mounting.
Does an aquarium affect Wi-Fi?
Yes, water is one of the best absorbers of radio waves. A large aquarium placed between the router and the room can significantly reduce the signal strength. Try to avoid routing the signal through water.
Will foil help boost the signal?
Foil can act as a reflector, redirecting the signal in the desired direction, but this is a crude method. It often creates interference zones and degrades reception in other parts of the house. It's better to properly position the router or buy an amplifier.
Where is the best place to place a router in a two-story house?
In a two-story house, the ideal location is the geometric center of the house, preferably on the ceiling of the first floor or in the middle of the stairwell. This will ensure coverage of both floors. If there's only one router, the signal will be weaker on the second floor.
