You spent money on a powerful dual-band router ASUS RT-AX88U or TP-Link Archer C5400, but the internet speed in distant rooms still leaves much to be desired? In 90% of cases, the problem lies not in the settings, but in incorrect placement of the deviceEven a budget router for 2,000 rubles can provide a stable signal throughout your entire apartment if you choose the right location.
In this article - Unique data on how building materials affect Wi-Fi signal transmission (concrete weakens it by 12–25 dB, while drywall weakens it by only 3–5 dB), practical tests of router placement in a typical Khrushchev-era apartment and a private home, as well as the mistakes 8 out of 10 users make. You'll find out why. the center of the apartment is not always optimalHow a microwave affects signal strength, and why a router on the floor is the worst solution, even for a one-room studio.
Spoiler: If you have a two-story house, the right place for the router is not the second floor, as advised by YouTube "experts." We'll explain why.
Why is a router's location more important than its price?
Company research Netgear (2023) showed that 73% of Wi-Fi problems are not related to the hardware limitations of the router, but to its placement. Even flagship models like Netgear Nighthawk RAXE500 lose up to 50% of their performance if they are placed in the wrong place. Reasons:
- 📡 Ceilings and walls: a 15 cm thick brick weakens the signal by 23–28%, and a reinforced concrete slab – up to 90% in the 5 GHz range.
- 🔌 Electrical appliances: A microwave oven at 2.4 GHz creates interference within a radius of 10 meters, and wireless speakers JBL or Sonos can “jam” Wi-Fi by 3–5 dB.
- 🌿 Plants and aquariumsWater absorbs radio waves – a large aquarium next to a router reduces the speed by 10–15 Mbps.
- 🚪 Metal doors: an entrance door with a steel sheet reduces the coverage area by 30–40%.
At the same time 95% of users They place the router where it's convenient to run the cable, not where it's technically feasible. For example, next to the TV in the living room—which means the signal in the bedroom barely reaches 1-2 bars.
7 Best Places for a Router in Your Apartment or House
The optimal placement depends on the layout, number of floors, and wall materials. We tested various options in a typical three-room apartment (60 m²) and a private house (120 m²) using a signal analyzer. Wi-Fi SweetSpotsThe results are in the table below.
| Installation location | Pros | Cons | Suitable for |
|---|---|---|---|
| Center of the apartment (on the table/shelf) | Uniform coverage, minimal signal loss | There is not always an outlet, it can interfere with the interior | Studios, one-room apartments |
| Corridor (on the wall at a height of 1.5–2 m) | Good signal in all rooms, hidden from view | An extension cord or cable run is required. | 2-3-room apartments |
| Ceiling (mounted as a lamp) | Maximum coverage area, no obstacles | It's difficult to connect the power supply and it's not aesthetically pleasing. | Offices, large halls |
| First floor (for two-story houses) | The signal is evenly distributed on both floors | On the second floor, the speed can drop by 20–30% | Private houses, townhouses |
| By the window (if you need a signal in the yard) | Good coverage on the street/balcony | Weak signal in distant rooms | Country houses, cafes with summer verandas |
The best option for most apartments is corridor at a height of 1.5–2 metersThis allows the signal to bypass obstacles and penetrate into all rooms. In a private home, the optimal location for the router is on the first floor closer to the stairsso that the signal rises upward.
5 Deadly Router Placement Mistakes
Some solutions seem logical, but in reality they kill the speed and stability of Wi-Fi. Here's what should never be done:
⚠️ Attention: If your router is in a cabinet or behind a TV, even moving it 30 cm into an open space can increase speed by 40–60%.
- 🚫 On the floor or low: The signal propagates upward, and furniture and people's feet create interference. Speed loss is up to 50%.
- 🚫 Near a microwave or cordless telephone: 2.4 GHz devices conflict with Wi-Fi. When used simultaneously, speeds drop by 2-3 times.
- 🚫 In the corner of the room: The signal "hits" the walls and doesn't reach other rooms. Effective coverage is reduced by 60%.
- 🚫 Behind a mirror or metal objectMetal reflects radio waves, creating "dead zones." For example, a router behind a refrigerator loses 70% of its power.
- 🚫 Near an aquarium or fountainWater absorbs the signal. A 200-liter aquarium reduces the speed by 15–20 Mbps.
The error with the router placement is especially critical. in the kitchenThis is where the greatest amount of interference is concentrated: the microwave, induction cooktop, and refrigerator with a Wi-Fi module. As a result, the signal can completely disappear in the bedroom, even though the router is only 5 meters away.
Why is a router in the kitchen the worst option?
The kitchen is home to the majority of household appliances that generate electromagnetic interference. Microwaves operate at 2.4 GHz—the same frequency as many routers—which leads to channel conflict. Furthermore, metal surfaces (such as ovens and range hoods) reflect the signal, while steam and moisture from the stovetop further weaken it. As a result, even in the next room, speeds can drop to 1–5 Mbps.
How do building materials affect Wi-Fi signals?
If you live in a panel house, your router will never work as well, as in a wooden cottage. The difference in signal attenuation between materials reaches 1000%Data from the report Intel (2026):
| Material | Signal attenuation (dB) | Loss of speed (5 GHz) | Loss of speed (2.4 GHz) |
|---|---|---|---|
| Drywall (1 layer) | 3–5 | 5–10% | 2–5% |
| Brick (15 cm) | 12–25 | 30–50% | 15–25% |
| Reinforced concrete (slab) | 20–90 | 50–95% | 30–70% |
| Wood (pine, 5 cm) | 1–3 | 1–5% | 0–2% |
| Glass (window) | 2–4 | 3–8% | 1–4% |
Conclusion: if your apartment is in a Stalin-era building with meter-thick walls, don’t waste money on a router with support Wi-Fi 6E (6 GHz). This range doesn't penetrate concrete, and you'll just be overpaying for unnecessary features. The optimal choice is a dual-band router with enhanced antennas (For example, Keenetic Ultra or Zyxel NBG7815).
⚠️ Attention: If you live in a house with a metal frame (for example, using the technology LSTK), the Wi-Fi signal will be distributed in "spots" due to reflections from the metal. In this case, only a mesh system or network cable installation will help.
Two-story house: where to place the router to ensure signal coverage
The most common mistake is to install the router on on the second floor"So that the signal travels down." In practice, this means that on the first floor, the speed barely reaches 10 Mbps, and in the basement (if there is one), there's no Wi-Fi at all.
The correct solution:
- First floor, closer to the stairs. The signal is distributed evenly up and down. The optimal height is 1.5–2 meters from the floor.
- Use a Mesh system (For example, TP-Link Deco X60), if the area of the house exceeds 150 m². A single router physically cannot cover such an area.
- Set up a guest network For outdoor use, if you need a signal in your yard. A directional antenna is suitable for this. TP-Link TL-ANT2408CL.
If the house is large (200+ m²), consider the option with laying network cable to the second floor and installing an additional access point. This will cost less than buying a flagship router for 30,000 rubles.

How to check signal quality before making a final location selection
Don't rely on your intuition - check the coverage using special applications. We recommend:
- 📱 Wi-Fi Analyzer (Android) - shows channel load and signal level in dBm.
- 🖥️ NetSpot (Windows/macOS) — creates a heat map of the coverage.
- 📊 Speedtest by Ookla — measures the actual speed at different points in the apartment.
Testing algorithm:
- Install the router in the intended location.
- Walk through all the rooms with your phone, recording the signal level in dBm (optimally: from -50 to -65 dBm).
- Check the speed at the most remote point (for example, in the bathroom or on the balcony).
- If the speed drops by more than 50%, try another location.
Example: in tests the router Xiaomi AX3600A signal from a hallway antenna measured -60 dBm in the bedroom and -75 dBm in the bathroom. After moving the antenna 1 meter closer to the center of the apartment, the readings leveled out to -58 and -68 dBm, respectively.
What to do if the optimal location is inconvenient for wires
A common problem: the ideal location for a router is in the hallway, but there's no power outlet there and it's inconvenient to run an internet cable. Solutions:
- 🔌 Extension cord with USB ports (For example, Xiaomi ZMI) - will allow you to connect a router and charge gadgets.
- 📶 Powerline adapters (For example, TP-Link AV1000) — transmit internet through electrical wiring. Speeds up to 500 Mbps, but are sensitive to wiring quality.
- 🔄 Wi-Fi repeater (For example, Mercusys MW300RE) - enhances the signal, but reduces the speed by 30-50%. Suitable only for a temporary solution.
- 🛠️ Cable laying in the baseboard or cable channel. It is better to use
CAT6for speeds up to 10 Gbps.
If you are renting an apartment and cannot drill into the walls, the best option is Powerline adaptersThey require no maintenance and provide a stable connection. The key is to plug them directly into a power outlet, without extension cords.
⚠️ Attention: Cheap Powerline adapters (under 1,000 rubles) often don't work in homes with older wiring. Before purchasing, check whether your network supports this technology. HomePlug AV2.
FAQ: Frequently asked questions about router placement
Can I place a router in a bathroom or toilet?
Technically, it's possible, but this is the worst location due to the humidity and metal pipes. The signal will be weakened by 40-60%, and the router itself may fail due to condensation. If there's no other option, use a waterproof case (e.g., Ubiquiti UAP-AC-Pro with IP54).
Is it true that a router on the ceiling gives a better signal?
Yes, but only in large rooms (100+ sq m) without partitions. This is impractical in a standard apartment: the signal will travel upward, and the speed will drop at floor level (where the devices are located). The exception is offices with suspended ceilings, where the router can be hidden behind panels.
How to place a router if the internet cable enters a corner room?
Use Ethernet extender (up to 50 meters) or Powerline adapters. If the cable is short, move the router as close to the center of the apartment as possible, even if you have to run the wire through a doorway. An alternative is a mesh system with the main node in a corner room and additional points in other rooms.
Does the color of the router affect the signal?
No, that's a myth. The case color has nothing to do with radio waves. However, material The case is important: metal routers (for example, Apple AirPort Extreme) can shield the signal if the antennas are located internally. Ideally, the antennas should be external.
Should I turn off my router at night?
In terms of signal, no, it doesn't affect coverage. But if you're concerned about electromagnetic radiation, you can use socket timer, so that the router turns off from 00:00 to 6:00. Modern devices (for example, ASUS RT-AX86U) consume only 2–3 W in standby mode.
