The problem of weak signal in distant rooms or on the balcony is familiar to many ISP subscribers. When the internet speed is good enough to watch 4K video in one part of the apartment, while a page takes forever to load in another, it requires immediate attention. Users often blame the ISP, although the cause lies in the propagation of radio waves or improperly configured equipment.
Company devices Rostelecom, whether it be RT-IX, Sagemcom or Sercomm, operate according to standard physical laws. The signal weakens when passing through walls, mirrors, and household appliances. Fortunately, there are many ways to improve network coverage without having to install new cables throughout the entire apartment.
In this article, we'll take a detailed look at how to expand your signal coverage using both free software and additional equipment. You'll learn how to properly position antennas and select available frequencies.
Optimal router placement
The first thing to consider is the physical location of the device. Many users hide the router in a niche under the TV or behind a cabinet, trying to conceal it from view. This is a serious mistake. Metal surfaces and thick concrete walls with reinforcement are an impenetrable barrier to radio waves. Central location in an apartment - the ideal solution for uniform coverage.
If the center of your apartment is inaccessible, try elevating the device. Antennas radiate primarily downward and to the sides, resembling a donut. On the floor or under a table, furniture absorbs a significant portion of the energy. It's also critical to keep the router away from sources of electromagnetic interference.
⚠️ Caution: Microwave ovens and baby monitors operate on the 2.4 GHz frequency and can completely jam your WiFi when turned on. Keep these devices away from each other.
Antenna orientation also plays a role. If the antennas are detachable, try adjusting their angle. A vertical position usually provides better coverage, but if the router is on a different floor, one of the antennas can be positioned horizontally.
Setting up frequency ranges and channels
Modern routers Rostelecom They support two bands: 2.4 GHz and 5 GHz. The former has a longer range but is heavily influenced by neighboring networks. The latter offers high speeds but has poorer wall penetration. To extend the range, it's best to optimize the 2.4 GHz band first.
The key parameter here is channel selection. In apartment buildings, the airwaves are clogged with dozens of networks that interfere with each other. You need to go to the router's web interface and find the setting. ChannelInstead of a regime Auto It's worth trying to manually select channels 1, 6 or 11, as they do not overlap.
- 📡 Download a WiFi analysis app on your smartphone (for example, WiFi Analyzer).
- 🔍 Find the channel that is least loaded by neighbors.
- ⚙️ Log in to your router settings at 192.168.1.1 or 192.168.0.1.
- 🔧 In the wireless network section, manually set the found free channel.
It's also worth paying attention to the channel width. For maximum range in the 2.4 GHz band, it's best to set it to 20 MHz. Mode 40 MHz provides higher speed near the router, but drastically reduces wall penetration and resistance to interference.
Transmitter power and safety standards
Wireless settings often hide a parameter that controls the signal strength. Device interfaces Rostelecom it can be called Transmit Power, Transmitter power or Tx PowerBy default, this setting can be set to 50% or 75% to save energy or reduce radiation.
Changing this value to High or 100% This significantly increases the coverage area. However, keep in mind that the router may become hotter at maximum power. Make sure the device is in a well-ventilated area and not obstructed by any objects.
| Parameter | Recommended value | Impact on signal |
|---|---|---|
| Power (Tx Power) | High / 100% | Maximum radius |
| Channel width (2.4 GHz) | 20 MHz | Better wall penetration |
| Opening hours | 802.11n / mixed | Compatibility with all devices |
| WMM | Enabled | Multimedia traffic priority |
Another important point is the encryption standard. Using outdated WEP or mixed mode WEP/WPA may cause the router to operate less efficiently. It is recommended to set the router to forced mode. WPA2-PSK (AES)This will not only secure the network but also reduce the unnecessary load on the router's processor associated with supporting older protocols.
Why is AES better than TKIP?
TKIP encryption is outdated and limits WiFi speed to 54 Mbps. It also places additional load on the router's processor, which can reduce connection stability. AES is faster and more secure.
Using repeaters to expand coverage
If software adjustments don't produce the desired result, you'll have to resort to hardware solutions. The most affordable option is installing a WiFi repeater. This is a small device that plugs into a power outlet at the edge of the coverage area and broadcasts the signal further.
For subscribers Rostelecom Branded repeaters or universal models from are often available TP-Link, Xiaomi And KeeneticThe setup process is usually simple: the device connects to the main network and clones its name and password, or creates a new network with a set-top box _EXT.
It's important to choose the right location for the repeater. It should be located where the signal from the main router is still strong but beginning to weaken. If you place the repeater in a "dead zone," it won't have anything to boost, and the output speed will be low.
- 🏠 Find a room where the signal is already weak, but still detectable.
- 🔌 Plug the repeater into a power outlet in this zone (or closer to the router for configuration).
- 📱 Set up your device via a mobile app or browser.
- 📍 Move the repeater to the final installation point after checking the connection.
⚠️ Please note: Using a repeater always reduces the actual internet speed by approximately half, since the device must receive and transmit data alternately on the same frequency.
Creating a Mesh System Instead of a Regular Router
A more modern and effective solution for larger apartments and houses is Mesh technology. Unlike repeaters, a Mesh system creates a single, seamless network. Devices automatically choose the optimal data path, and your phone automatically switches between access points without losing the connection.
Many new routers Rostelecom (series RT-IX (and newer) already support EasyMesh technology. This means you can buy a compatible second router or a dedicated mesh point and connect them into a single system. Unfortunately, older models don't offer this feature.
Mesh's main advantage is its intelligent traffic distribution. If you're moving around your apartment while on a video call, the system will automatically switch you to the nearest point with the best signal. This eliminates the need to manually switch between different networks.
☑️ Are you ready for the Mesh system?
Antenna replacement and equipment upgrades
If your router Rostelecom has removable antennas that can be replaced with more powerful ones. The standard connector is usually of the type SMA or RP-SMAPurchasing antennas with a gain of 5 dBi or 7 dBi instead of the standard 2-3 dBi can provide a noticeable increase in signal strength.
However, it's important to understand the physics of this process: high-gain antennas change the radiation pattern. They "flatten" the signal, making it more horizontal. This works well within a single floor, but can degrade reception on floors above or below.
In some cases, it makes more sense to replace the router itself. Older devices issued by your provider several years ago may have weak processors and outdated Wi-Fi standards. Buying a modern router with support WiFi 6 (802.11ax) and powerful external antennas will solve the coverage problem radically.
Frequently Asked Questions (FAQ)
Can foil boost a router's signal?
In theory, foil can act as a reflector, directing the signal in the desired direction. However, in practice, the effect is often unpredictable: foil can create interference or block the signal in other directions. It's much more effective to properly configure the channels or purchase a repeater.
Does the number of connected devices affect the range?
The number of devices doesn't affect the physical range of a radio wave. However, with a large number of active clients, the router's processor becomes overloaded, which can lead to packet loss and a perceived "weak" internet connection, even if the signal strength is full.
Is it worth updating the firmware of a Rostelecom router?
Yes, manufacturers regularly release updates that improve the stability of the wireless module and fix bugs. You can check for a new version in your personal account or through the web interface in the "Updates" section. System → Software Update.
Why does the internet work worse in the evening than during the day?
In the evenings, neighbors also use the internet actively, which creates high airtime congestion, especially on the 2.4 GHz frequency. In this case, switching to a less congested channel or using the 5 GHz band can help.
