Have you noticed that the Wi-Fi from the router Rostelecom Does the connection "not reach" distant rooms, and in some corners of the apartment the connection constantly drops? The problem may not be with the plan or the internet speed, but with limited wireless network rangeProviders often list "up to 100 meters" in device specifications, but in practice, coverage is reduced by 3-5 times due to walls, furniture, and interference from neighboring networks.
In this article you will learn how accurately measure the Wi-Fi range your router Rostelecom, what parameters affect it, and what to do if the signal is weak. We'll cover both software methods (via router settings and mobile apps) and practical tests using readily available tools. For those looking to expand their coverage, we'll provide proven methods—from changing the broadcast channel to installing repeaters.
Important: The range depends not only on the router model (for example, Sagemcom [Fast] 5365 or Sercomm RV6699), but also from surrounding environmentEven two identical devices in different apartments can show different results. Therefore, there are no universal figures—only individual measurements.
1. Rostelecom router specifications: what affects Wi-Fi range
Before measuring coverage, it's important to understand what it depends on. The main parameters that determine the range are:
- 📡 Wi-Fi standard: routers Rostelecom support
802.11n(up to 300 Mbps) or802.11ac(up to 1.2 Gbps). Devices withWi-Fi 6 (802.11ax)are less common, but provide better coverage due to technology MU-MIMO. - 🔋 Transmitter power: in most models it is fixed at the level
100 mW (20 dBm). Exception: some firmware allows you to increase the power up to200 mW, but this may violate Russian laws on radio frequencies. - 🌐 Broadcast frequency:
2.4 GHz— better through walls, but susceptible to interference from other devices (microwaves, Bluetooth). Radius: up to 30–50 m in ideal conditions.5 GHz— higher speed, but poorer penetration through obstacles. Radius: up to 15–25 m.
- 📶 Number of antennas: routers with
2×2 MIMO(two antennas) cover a larger area than with one. For example, Sercomm RV6699 has two external antennas, which improves signal stability.
Manufacturers often indicate maximum radius in the technical specifications, but these figures were obtained in laboratory conditions—without walls, furniture, or interference. Actual coverage may be 2–4 times less. For example, for the model Sagemcom 2804 v7 It says “up to 100 m”, but in a city apartment the signal will hardly cover 15–20 m through 2–3 walls.
⚠️ Attention: In Russia, there are restrictions on the power of Wi-Fi transmitters (no more than100 mWFor2.4 GHzAnd200 mWFor5 GHz). Exceeding these values may result in fines from Roskomnadzor. Do not change power settings unless you are sure they are legal.
| Router model | Wi-Fi standard | Max. radius (declared) | Real radius (apartment) | Number of antennas |
|---|---|---|---|---|
| Sagemcom [Fast] 5365 | 802.11n (2.4 GHz) |
up to 100 m | 10–20 m | 1 internal |
| Sercomm RV6699 | 802.11ac (2.4 + 5 GHz) |
up to 150 m | 15–30 m | 2 external |
| Huawei HG8245H | 802.11n (2.4 GHz) |
up to 80 m | 8–15 m | 1 internal |
| ZTE ZXHN H298A | 802.11ac (2.4 + 5 GHz) |
up to 120 m | 12–25 m | 2 external |
If your router is not listed in the table, find its model on the sticker on the back of the device (e.g. RTK G32 v1.0) and check the specifications on the website Rostelecom or in the instructions. Please pay attention to number of antennas and supported frequencies — these are the key parameters for assessing coverage.
2. Method 1: Checking the radius via the router's web interface
The most accurate way to find out the current Wi-Fi range is to look signal strength (RSSI) in the router settings. To do this:
- Connect to the router via cable or Wi-Fi.
- Open your browser and type in the address bar
192.168.1.1or192.168.0.1(the address may differ - look on the device sticker). - Enter your login and password (usually
admin/adminor indicated on the router). - Go to the section
Wi-Fi → Status(orWireless → Statistics).
Here you will see the parameter Signal Strength or RSSI (in dBm). The closer the value is to 0, the stronger the signal. Approximate decoding:
- 🟢
-30 dBmto-50 dBm- excellent signal (full speed). - 🟡
-50 dBmto-70 dBm— average signal (speed loss is possible). - 🔴
-70 dBmto-90 dBm- weak signal (connection breaks). - ⚫
-90 dBmand below - there is practically no connection.
To estimate the radius, walk around your apartment with a laptop or phone connected to Wi-Fi and monitor the change RSSI in the router settings. Note the point where the signal drops below -70 dBm - this is what will happen maximum radius of stable coverage.
⚠️ Attention: Some routers Rostelecom (For example, Sagemcom 2804) don't show RSSI in the web interface. In this case, use the alternative methods in the following sections.
3. Method 2: Measuring the radius using mobile apps
If you don’t want to go into the router settings, you can use special applications for smartphones, which show the Wi-Fi signal strength in real time. The best options are:
- 📱 WiFi Analyzer (Android) - shows a signal strength graph, channel occupancy, and even creates a heat map of coverage.
- 🍎 AirPort Utility (iOS) - A built-in app from Apple that displays
RSSIfor connected networks. - 🌍 NetSpot (Windows/macOS) - A professional tool for creating a Wi-Fi coverage map.
How to measure radius using WiFi Analyzer:
- Install the app from Google Play.
- Connect to your Wi-Fi network.
- Open the tab
Signal Meter. - Walk around the apartment, observing the graph. Mark the points where the signal drops.
-70 dBm.
For more accurate measurements, use the function Signal History - it saves the history of changes RSSI over time. This way, you can see how the signal weakens as you move further away from the router.
How to build a heat map in NetSpot?
To create a heat map in NetSpot you need to:
1. Upload the apartment plan (or draw it manually in the app).
2. Indicate the measurement points by walking through the rooms with a laptop.
3. The program will automatically generate a coverage map with color indication of signal strength.
4. Export the result to PDF for analysis.
Applications also help to identify interference from neighboring networksFor example, if your router is operating on channel 6, and there are 3 other networks nearby using the same channel, the signal will be weaker. In this case, it's worth change the channel in the router settings (more on this in section 5).
4. Method 3: Practice tests with a laptop or smartphone
If you don't want to install applications, you can do without built-in tools Windows, Android, or iOS. Here's how to do it:
On Windows:
- Connect to Wi-Fi.
- Click
Win + R, entercmdand pressEnter. - Enter the command:
netsh wlan show interfaces - Find the line
Signal- the signal strength percentage will be indicated there (for example,95%).
On Android:
- Open
Settings → Wi-Fi. - Click on the name of your network.
- Look at the meaning
Signal level(usually displayed as bars or a number in dBm).
On iOS:
- Hold your finger on the Wi-Fi icon in
Control center. - A signal strength indicator will appear next to yours in the list of networks (the more filled arcs, the better).
To accurately measure the radius:
- Stand next to the router and record the initial signal level (for example,
-40 dBm). - Walk away from the router in a straight line, recording readings every 2–3 meters.
- Stop when the signal drops to
-70 dBm— this is the boundary of stable coverage.
Repeat the test in different directions (for example, towards the kitchen, bedroom, balcony), as walls and furniture absorb the signal differently. Metal surfaces, mirrors and concrete partitions weaken Wi-Fi the most.
Take a laptop or smartphone with Wi-Fi
Install a signal monitoring app (optional)
Prepare a notebook for recording indicators
Check the signal at 5-7 key points in the apartment
Compare results with RSSI table-->
5. Method 4: Using specialized programs (for advanced users)
If you need professional data To check Wi-Fi coverage, use network analysis programs:
- 🖥️ inSSIDer — shows all networks within range, their channels, signal width, and signal strength. Suitable for selecting the optimal channel.
- 📊 Acrylic Wi-Fi — builds graphs of signal changes over time, allows you to export data to
CSV. - 🌐 Ekahau HeatMapper — creates a heat map of coverage (free version is limited to 2 AP).
Example of working with inSSIDer:
- Download and install the program from the official website.
- Start scanning (
Start Scan). - Find your network in the list and note the columns:
RSSI— signal strength;Channel— the channel used;Width— channel width (20/40 MHz).
RSSI.These programs also help to identify channel blocking with neighboring networks. If your router is on the same channel 1, and the neighboring one is on 2, they will interfere with each other. The optimal solution is to choose a channel with minimal congestion (for example, 11 or 13 For 2.4 GHz).
⚠️ Attention: In Russia for2.4 GHzchannels with are allowed1By13, but the channels12And13may not be available on some devices (especially those imported from the US). Channels14and higher use is prohibited.
If you find that your channel is overloaded, change it in your router settings:
- Go to the web interface (
192.168.1.1). - Go to
Wi-Fi → Basic Settings. - In the field
Channelchoose a free one (for example,6instead of1). - Save the settings and reboot the router.
6. Method 5: Estimating the radius based on internet speed
Signal strength (RSSI) is good, but the main criterion for the user is real internet speedEven if -60 dBm Speed may drop due to interference. Therefore, it's worth conducting a speed test in different areas of the apartment.
How to do it:
- Connect to Wi-Fi.
- Open the service
speedtest.netornperf.com. - Run a test near your router and record your download/upload speed.
- Move away 5-10 meters and repeat the test.
- Compare the results. If the speed has dropped by more than 50%, you have reached effective coverage boundaries.
- 📍 Place the router in the center of the apartment, and not in the corner.
- 🚫 Get him away from metal objects, mirrors and microwaves.
- 🔝 Place it on a raised surface (for example, on a cabinet) - this way the signal is less likely to be blocked by furniture.
- 🔄 In the router settings (
192.168.1.1) change the channel to a less busy one (see section 5). - 📶 For
2.4 GHzset the channel width20 MHz(and not40 MHz) - this will reduce interference, but will slightly reduce the speed.
Example of interpretation of results:
| Distance from the router | Signal strength (RSSI) | Speed (Mbps) | Connection quality |
|---|---|---|---|
| 1 m | -35 dBm |
100/100 | Excellent |
| 10 m (1 wall) | -55 dBm |
80/85 | Good |
| 15 m (2 walls) | -68 dBm |
30/40 | Satisfactory |
| 20 m (3 walls) | -80 dBm |
5/10 | Bad (breaks) |
If the speed at the boundary of the coating drops below 10 Mbps, it's worth thinking about signal amplification (More on that in the next section). Also, pay attention to ping (delay): if it exceeds 100 ms, the connection will be unstable for online games or video calls.
7. How to increase the range of a Rostelecom Wi-Fi router: 5 effective methods
If your measurements show that the signal doesn't reach the required rooms, don't rush to buy a new router. 5 Ways to Expand Your Coverage without serious expenses:
1. Optimizing the router location
2. Changing the channel and bandwidth
3. Firmware update
Manufacturers regularly release updates to improve Wi-Fi stability. To update the firmware:
- Go to
System → Software Update. - Click "Check for updates".
- If a new version is available, install it and reboot the router.
4. Using a repeater
If the previous methods did not help, buy Wi-Fi repeater (For example, TP-Link TL-WA850RE or Xiaomi Wi-Fi Repeater 2). It connects to your network and retransmits the signal, increasing the radius by 10–20 m. Price: from 1,000 to 3,000 rubles.
5. Replacing antennas (for routers with removable antennas)
Some models (eg Sercomm RV6699) allow you to connect external antennas with gain (5–9 dBi). This can increase the range by 20–30%. The main thing is to choose an antenna with a connector. RP-SMA (check compatibility!).
⚠️ Attention: Installation of antennas with a gain of more than 6 dBi May require registration with Roskomnadzor. Check the legal requirements for your region before purchasing.
8. Common Mistakes When Measuring Wi-Fi Range
Many users make mistakes that distort the measurement results. Here's what you can't do it:
- 📵 Use only one device for testingA laptop and smartphone may show different signal levels due to different Wi-Fi modules.
- 🔄 Ignore interferenceIf your neighbor's router is on the same channel, your signal will be weaker, even over a short distance.
- 📡 Measure the signal at only one pointWi-Fi is not distributed evenly - there may be a spot in one corner
-50 dBm, and in the other --80 dBm. - 🕒 Ignore the time of dayIn the evening, when all the neighbors are at home, there is more interference, and the coverage radius may decrease.
Another common mistake is ignoring the 5 GHz frequencyMany routers Rostelecom support dual-band Wi-Fi, but users only connect to 2.4 GHz, since it “hits further.” However, on 5 GHz the speed is higher, and in some cases (for example, in apartments with thin walls) the radius can be comparable to 2.4 GHz.
To objectively evaluate the coverage, take measurements:
- 🕘 At different times of the day (morning/evening).
- 📱 On different devices (smartphone, laptop, tablet).
- 🌐 On both frequencies (
2.4 GHzAnd5 GHz).
FAQ: Answers to Frequently Asked Questions
🔍 How do I find out the model of my Rostelecom router?
The model number is indicated on a sticker on the back or bottom of the device. It usually begins with the manufacturer's name: Sagemcom, Sercomm, Huawei or ZTEThe model can also be seen in the web interface (192.168.1.1) in the section System → Information.
📶 Why is the 5 GHz Wi-Fi range smaller than 2.4 GHz?
Frequency 5 GHz has a shorter wavelength, so it has a harder time penetrating obstacles. However, it is less susceptible to interference and provides greater speed. Under ideal conditions (line of sight), the difference in radius between 2.4 GHz And 5 GHz can reach 30–50%.
🔌 Is it possible to increase the router's transmitting power?
Technically yes, but in Russia it is forbidden without special permission. The maximum permitted power for 2.4 GHz — 100 mW (20 dBm)Exceeding this limit may result in fines from Roskomnadzor. It's better to use legal methods: changing the channel, repeaters, or mesh systems.
🏠 What Wi-Fi range does a private home need?
For a house up to 100 m², a standard router is usually sufficient (radius 15–25 m). For large houses (150 m²+) you will need:
- Installation Mesh systems (For example, TP-Link Deco).
- Usage access points with cable connection.
- Replacing the router with a model with external antennas (For example, ASUS RT-AX88U).
In wooden houses the signal spreads better than in brick or concrete ones.
🔄 What should I do if the radius hasn't increased after changing the channel?
If changing the channel doesn't help, try:
- Reduce channel width to
20 MHz(For2.4 GHz). - Disable the feature
WPS- She sometimes creates interference. - Check if the router is overheating (place it in a ventilated area).
- Update your firmware to the latest version.
If all else fails, consider purchasing a repeater or a new router.
