Modern internet surfing and high-definition video streaming require a stable and fast connection, which directly depends on the frequency band your equipment operates on. Many ISP subscribers often wonder what frequency their device operates on, as this affects data transfer speeds and signal coverage in their home. Understanding the difference between 2.4 GHz And 5 GHz helps you set up your gadgets correctly and avoid interference from neighboring networks.
Determine the operating frequency of the router Rostelecom There are several ways to do this, from a visual inspection of the case to in-depth diagnostics via the web interface. Depending on the device model (whether it is Sagemcom, Eltex or ZTE) the methods may differ slightly, but the general principle remains the same for all.
In this article, we'll take a detailed look at all available verification options, explain the technical nuances, and help you choose the optimal range for your needs.
Visual inspection and device specifications
The fastest way to get initial information is a physical inspection of the equipment installed in your home. Telecommunications equipment manufacturers almost always list key specifications on a sticker located on the bottom or back of the case. Look for lines with the word Wireless or Wi-Fi, where the supported standards will be listed.
If you see the designation on the sticker 802.11n, then most likely the device operates exclusively in the 2.4 GHz range. The presence of markings 802.11ac or Wi-Fi 5 guarantees support for the faster 5 GHz band. Modern models, such as RT-PI-1 or Sagemcom F.AST, are often dual-band, meaning they operate on both frequency spectrums simultaneously.
⚠️ Attention: The presence of "Dual Band" or "AC" on the box or sticker doesn't mean the 5 GHz function is already activated. Often, providers leave this band disabled by default or combined into a single network with smart switching.
It's also worth paying attention to the number of antennas. While the number of antennas doesn't always directly correlate with frequency, models with four or more antennas are most often classified as AC1200 and higher, which means operation in both bands. Older single-band models usually have a single antenna and operate only at 2.4 GHz.
Diagnostics via the router's web interface
The most reliable method for obtaining information is to log into the device's admin panel. To do this, connect to the router's network via cable or Wi-Fi and enter the gateway IP address (usually 192.168.1.1 or 192.168.0.1) in the browser's address bar. After logging in (the login and password are also indicated on the sticker), the main settings menu will open.
Interfaces of different models Rostelecom may look different, but the logic behind the wireless network settings is universal. You need to find the section called WLAN, Wi-Fi or "Wireless Network." Within this section, there are often tabs or subsections called "Basic Settings" and "Advanced Settings."
In the menu that opens, pay attention to the field Channel (Channel) or Band (Range) If a range is specified there 2.4G or channels 1 through 13, you're in the low-frequency module settings. To check for 5 GHz, look for a separate tab. 5G or switch Band Selection.
☑️ Check in the web interface
In some firmware, especially on devices Eltex or ZTE, the function is used Smart Connect, which combines both frequencies under a single network name (SSID). In this case, the web interface will have a check mark next to "Enable Smart Connect" or "Combine Bands." Disabling this feature will result in two separate network names, for example, Home_WiFi And Home_WiFi_5G.
Using the Rostelecom mobile application
For users who find it difficult to work with browser settings, the provider has developed a convenient mobile application RostelecomThis tool allows you to manage your home network from your smartphone anywhere in the world, as long as you have internet access. The app automatically detects your router model and displays its status.
After logging into your account through the app, select your device from the list. The main screen often displays the current channel load and connection type. By tapping "My Network" or "Wi-Fi," you can see detailed information about access points. If your router is dual-band, the app will offer to set up a guest network or change the main broadcast settings.
The advantage of the mobile method is that the interface is adapted for inexperienced users and free of complex technical jargon. Here, you can immediately see whether the 5 GHz band is activated and rename networks by adding a prefix. _5G for easy identification on your gadgets.
Network analysis using a smartphone or laptop
You can find out the frequency by simply analyzing the list of available Wi-Fi networks around you. Modern smartphones based on Android And iOS, as well as laptops with Windows 10/11, display additional information about the connection. If you see two networks with the same name, but one of them has a suffix 5G or 5GHz, which means your router is broadcasting both ranges.
On devices with Android You can click on the name of the connected network (or the gear icon next to it) to open its detailed properties. The "Frequency" line will display the following value: 2437 MHz (which corresponds to 2.4 GHz) or 5180 MHz and higher (5 GHz band). On iPhone, this information is hidden deeper and requires the use of third-party utilities.
For Windows laptop owners, there is a built-in command that provides a detailed report on the wireless adapter. Open the command prompt (cmd) and enter the following query:
netsh wlan show interfacesIn the received report, find the line Channel or Radio type. Type 802.11n most often indicates 2.4 GHz (although it can also be 5 GHz), and 802.11ac or 802.11ax — it's always 5 GHz. The channel number will give you a more precise answer: channels 1-14 are 2.4 GHz, and channels 36 and above are 5 GHz.
⚠️ Note: If your laptop or phone is older (more than 7-8 years old), it may not physically support the 5 GHz standard. In this case, you won't see high-frequency networks, even if your router is broadcasting them.
Comparison table of range characteristics
Understanding the technical differences will help you decide which range to use for specific applications. Below is a table comparing the key parameters of the two frequency ranges used in equipment. Rostelecom.
| Parameter | 2.4 GHz band | 5 GHz band |
|---|---|---|
| Maximum speed | Up to 150-450 Mbps | Up to 867 Mbps and higher |
| Penetration ability | High (passes through walls) | Low (fades strongly) |
| Channel congestion | Very high (a lot of interference) | Low (pure ether) |
| Range | Up to 40-50 meters | Up to 20-25 meters |
The table shows that 2.4 GHz is better for online gaming and watching 4K video in the next room due to its better signal penetration, despite its speed. However, for VR headsets and downloading large files within the same room, 5 GHz is the clear winner.
Why is 5 GHz worse at passing through walls?
The 5 GHz signal has a shorter wavelength. Shorter wavelengths are more easily absorbed by wall materials, especially those containing reinforcement or a thick layer of concrete, while longer wavelengths of 2.4 GHz are better at bypassing them.
Manual frequency tuning and separation
If you find out that your router Rostelecom Since both bands are supported, they are combined into a single network. It's recommended to separate them. This will allow you to force stationary devices (TVs, consoles) to connect to the fast 5 GHz band, while leaving smart plugs and vacuum cleaners on 2.4 GHz.
To do this, go to the section in the web interface WLAN need to find an option Smart Connect or Band Steering and move the switch to the position Off (Off). Once disabled, the fields for entering network names (SSIDs) for each band separately will become active. Give them descriptive names, for example, MyHome_24 And MyHome_50.
Don't forget to save the settings with the button Apply or SaveThe router may reboot. After that, two options will appear in the list of networks on your phone. Connect your phone to the 50 network and check the speed using the service. speedtest.net — the result should be significantly higher than at 2.4 GHz.
Frequently Asked Questions (FAQ)
Why can't I see the 5GHz network on my phone even though my router is dual-band?
Most likely, your smartphone is an older generation and has a Wi-Fi module that only supports the 802.11n (2.4 GHz) standard. It's also possible that the 5 GHz band is simply disabled or hidden in your router settings (SSID Broadcast: Disable).
Is it possible to increase the range of a 5GHz network?
Physical laws limit the range of high frequencies. However, you can try changing the router settings. Rostelecom Change the channel width from 80 MHz to 40 MHz. This will slightly reduce the maximum speed, but will improve signal stability and penetration range.
Does Rostelecom's tariff plan affect Wi-Fi frequency?
No, your tariff plan only determines the incoming internet speed from your provider. The Wi-Fi frequency (2.4 or 5 GHz) is a characteristic of your equipment (router). However, to achieve speeds above 100 Mbps, using the 5 GHz band is critical.
What should I do if the internet is lost after frequency separation?
Check that you entered the correct password when connecting to the new network. If the problem persists, try resetting the router to factory settings (button Reset on the case) and go through the setup procedure again through the installation wizard.
