Many users who have just connected to home Internet from a provider RostelecomMany people encounter situations where the connection speed on their smartphone or laptop is significantly lower than what's advertised in their plan. Often, the problem lies not with the provider's network, but with the physical limitations of the wireless signal, which simply doesn't reach the farthest rooms of an apartment or summer cottage. Understanding the range of a Rostelecom Wi-Fi router is a key step in planning a home network, especially if you live in a large apartment, private home, or office with multiple partitions.
In ideal laboratory conditions, free of walls, furniture, and interference from neighboring networks, standard equipment can extend a signal up to 100 meters in open areas. However, in an apartment building, concrete floors with reinforcement, mirrors, and household appliances create significant resistance to radio waves, reducing the effective coverage area to 20-30 meters within a single floor. It is important to take into account, that the range directly depends on the frequency range, antenna type, and version of the Wi-Fi standard installed on your device.
In this article, we'll take a detailed look at what determines connection stability, how different wall materials affect signal attenuation, and what specific steps can be taken to expand your signal coverage. You'll learn why dual-band routers perform better in noisy environments and whether it's worth purchasing additional equipment to eliminate dead spots.
Factors Affecting Wi-Fi Signal Range
The range of any router, be it a model from RT-K, Sercomm or ZTEThe range provided by your provider isn't a constant. There are many variables that can significantly reduce the stated range. First and foremost, these are physical obstacles: load-bearing walls made of reinforced concrete can absorb up to 90% of the signal's power, turning it into barely noticeable noise. Even drywall partitions with insulation inside can significantly reduce connection quality, not to mention water heaters or aquariums, which are excellent absorbers of radio waves.
⚠️ Attention: Avoid placing the router near microwave ovens, baby monitors, or high-power Bluetooth devices. These devices create electromagnetic interference that can completely block the signal over short distances.The second critical factor is frequency range. Standard Rostelecom routers typically operate in two bands: 2.4 GHz and 5 GHz. The 2.4 GHz band has better penetration and better obstacle avoidance, but is more susceptible to interference from neighboring networks. 5 GHz band It provides high speed, but its range is significantly shorter and it penetrates walls very poorly. If you need a signal in a distant room, switching to the 2.4 GHz frequency can increase coverage but will reduce maximum speed.
The number of connected devices and background processes also shouldn't be ignored. If people are downloading torrents, watching 4K videos, and playing online games simultaneously, the router's processor may be unable to handle the load, resulting in reduced data packet transmission performance. Antennas The devices act as amplifiers: the presence of external antennas with a high gain (dBi) allows you to focus the signal in a specific direction, increasing the range.

Understanding the difference between frequencies is 80% of the success in setting up a stable internet connection. Most modern Rostelecom routers are dual-band, meaning they broadcast two networks simultaneously. The 2.4 GHz band is the "workhorse," providing coverage over a larger area. It can penetrate more walls, but its throughput is limited, and the airwaves themselves are usually heavily polluted by signals from Bluetooth headphones, wireless mice, and neighbors' routers.
The 5 GHz band is the "highway." It delivers the maximum speeds supported by your plan and has virtually no interference in apartment buildings, as neighbors use this band less frequently. However, the physics of radio waves is such that a higher frequency means a shorter wavelength, and therefore less ability to bend around obstacles. Range 5 GHz in a room with concrete walls can be only 10-15 meters from the signal source.
What frequency should I choose for a smart home?
For smart home devices (light bulbs, sensors, plugs), always use the 2.4 GHz band. Most of these gadgets simply don't support 5 GHz. Furthermore, for transmitting small data packets (on/off status), the high speed of 5 GHz is excessive, while the penetration power of 2.4 GHz ensures stable operation even in remote locations.
The table below provides a comparison of the characteristics of the two ranges for clarity:
Characteristic 2.4 GHz band 5 GHz band Maximum speed Up to 150-300 Mbps (realistic) Up to 800+ Mbps (realistic) Penetration ability High (passes through 2-3 walls) Low (passes through 1 wall) Range Up to 30-40 meters indoors Up to 15-20 meters indoors Interference level High (neighbors, Bluetooth) Short To ensure the best coverage, we recommend using a split-band strategy: connect high-speed desktop devices (TVs, gaming consoles, PCs) to the 5 GHz network if they are in the same room as the router. Smartphones, tablets, and IoT devices located further away are best switched to the 2.4 GHz band for reliable reception.
The influence of wall materials and layout
The layout of your home can be the biggest enemy or friend of your Wi-Fi signal. Modern new buildings often feature monolithic concrete walls with metal reinforcement, which acts as a Faraday shield, almost completely blocking radio waves. In such conditions, even a powerful router might not penetrate a single wall. Older homes with wooden floors or foam block walls, on the other hand, allow the signal to pass through much more easily.
Particular attention should be paid to mirrors and glass. A large mirror on a cabinet or a glass interior partition can reflect the signal, creating complex interference patterns where the signal is excellent at one point, but completely disconnected a meter away. Metal trim elements and foil insulation behind wallpaper (used for thermal insulation) also pose a significant barrier.
If your router is installed in a weak enclosure in the hallway, closed with a metal door, you automatically lose up to 50% of the signal strength before it even reaches the living space. The optimal place for placing equipment - the center of the apartment, located at a height of at least 1.5 meters from the floor, in open access.
⚠️ Attention: If the walls contain metal wiring conduits or foil-lined insulation, the router's range may be minimal. In such cases, the only solution is to run a twisted-pair cable to distant rooms.Technical specifications of Rostelecom equipment
Provider Rostelecom usually provides subscribers with equipment from various vendors, such as Eltex, ZTE, Sagemcom or Keenetic (depending on region and plan). Basic models, often referred to as ONT terminals, have a built-in mid-power Wi-Fi module. Their antennas typically have a gain of around 2-3 dBi, which is sufficient to cover a standard 2-3-room apartment.
More advanced models, available at an additional cost or as part of promotions, are equipped with external antennas and support for technology MIMO (Multiple Input Multiple Output). This allows the device to use multiple antennas simultaneously for receiving and transmitting data, increasing throughput and connection stability. Some high-end models support the Wi-Fi 6 (802.11ax) standard, which more efficiently manages multiple connected devices and performs better in noisy environments.
It's also worth considering the age of the device. Routers manufactured more than five years ago may not support modern encryption and signal modulation standards, which limits their effective range compared to newer models. If your device is older, it might be worth considering replacing it or purchasing a more powerful device.
Methods for increasing coverage area
If you discover that your Rostelecom router's range isn't sufficient for your entire home, don't rush to blame the provider. There are several proven ways to expand your coverage without replacing the main equipment. The simplest and cheapest method is to reposition the router. Elevate it, move it away from electronics, and try to place it in the geometric center of your home.
If repositioning the antennas doesn't help, you can replace the stock antennas with more powerful ones, if your router model allows for detachable ones. Antennas with 5 dBi or 8 dBi gain can significantly improve the situation. However, keep in mind that higher antenna gain narrows the vertical signal propagation angle, so this method may be less effective in multi-story buildings.
More radical but effective methods include:
- 📡 Installing a repeater: The device is plugged into a power outlet at the edge of the coverage area and retransmits the signal further, expanding the coverage.
- 🌐 Mesh system: A set of several modules that create a single, seamless network. This is the best solution for larger homes, but it requires a financial investment.
- 🔌 Powerline adapters: They transmit internet through the regular electrical wiring in the house. Ideal if you need to connect the internet to a room with thick walls but an electrical outlet is available.

Completed: 0 / 4Common mistakes when placing a router
Many users make common mistakes that negate the benefits of even the most expensive equipment. The first and most common mistake is placing the router on the floor or behind a sofa. The signal travels from top to bottom and side to side, so hiding the signal source is absolutely essential. A floor covered with furniture will absorb most of the radiation.
The second mistake is installing the router next to a window. In this case, half of your signal (and half of the paid speed) escapes into the street, illuminating neighboring buildings, instead of being distributed inside your apartment. A window is an open door for radio waves, and you need to use this wisely by aiming the antennas toward the interior.
The third mistake is ignoring heat. A router left in direct sunlight or covered with papers overheats. When overheated, the processor reduces its performance (throttling), leading to slower and more unstable Wi-Fi, which is often mistaken for a poor signal.
⚠️ Attention: Router settings interfaces and capabilities may vary depending on the model and firmware version. If you don't find the described functions in your account or web interface, check the official instructions on the device manufacturer's website.FAQ: Frequently Asked Questions
Can a Rostelecom router penetrate two concrete walls?
A standard router with internal antennas is unlikely to provide stable speeds through two solid concrete walls. The signal may remain, but its quality will be poor, with constant interruptions. For such cases, using a repeater or Powerline adapters is recommended.
Why does my phone have Wi-Fi, but my laptop doesn't?
This is due to differences in the transceiver modules. Modern smartphones often have more sensitive antennas and newer Wi-Fi standards than older laptops. Furthermore, the laptop's Wi-Fi adapter drivers may be outdated.
Does the number of connected devices affect the range?
Physically, the range (signal strength) doesn't change with the number of devices. However, the channel bandwidth is divided among all users. If the channel is congested, devices at the edge of the coverage area will be the first to lose a stable connection, creating the illusion of a reduced range.
Is it worth buying a router with 4 antennas instead of 2?
Yes, if you have a large area or many walls. Additional antennas enable MIMO and Beamforming technologies, which direct the signal specifically to your device, improving connection quality over a longer distance.
