The modern internet demands high speed and connection stability, and users of internet providers often face the need to understand the technical specifications of their equipment. The question is, How to find out the frequency of a Rostelecom Wi-Fi router, becomes especially relevant when trying to set up a smart home, connect a gaming console, or troubleshoot low data speeds. Understanding the difference between the 2.4 GHz and 5 GHz bands is the first step to optimizing your home network.
Many subscribers don't even realize that their device can operate in two bands simultaneously or, conversely, be limited to only one standard. This directly affects how quickly large files will download and whether 4K video will stutter. In this article, we'll cover all the frequency identification methods in detail, from visual inspection of the device to in-depth configuration via the web interface.
You don't need to be a communications engineer to perform these tests. Just follow the step-by-step instructions and carefully read the model names and menu options. We'll cover both standard routers and popular devices. Sagemcom, Sercomm And Eltex, which are most often issued by the operator.
Visual identification and marking of equipment
The easiest and fastest way to get basic information about your router's capabilities is to carefully inspect the device itself. Network equipment manufacturers typically list key specifications on a label located on the bottom of the device. Look for markings that include wireless standards, such as 802.11ac or 802.11nIf you see markings AC, this virtually guarantees support for the high-speed 5 GHz band.
Also, pay attention to the number of antennas. While this isn't always a reliable indicator, routers with four or more antennas are most often dual-band. However, appearances can be deceiving, as some models with multiple antennas use MIMO technology to boost the signal in only one band. Therefore, this visual method should only be used as a preliminary assessment.
⚠️ Note: Don't rely solely on the number of antennas. There are models with three antennas that operate exclusively at 2.4 GHz, and compact devices without external antennas that support 5 GHz.
For a precise identification, check the device model number listed on the same sticker. Entering this model number into a search engine will instantly retrieve the specifications from the manufacturer's official website. This is especially helpful if the sticker is worn or difficult to read.
Checking via the router's web interface
The most reliable method for obtaining information is to log into the router's control panel. To do this, connect your computer or smartphone to the router's network and enter the device's IP address in the browser's address bar. This is usually 192.168.1.1 or 192.168.0.1After entering your login and password (often found on a sticker), you'll be taken to the settings menu.
Interfaces for different models Rostelecom may differ, but the search logic remains the same. You need to find the section responsible for the wireless network. It may be called WLAN, Wi-Fi, Wireless network or WirelessWithin this section, look for subsections with the names Basic, Basic settings or Radio.
Here you'll see switches or lists indicating the frequency. If your router is dual-band, you'll be able to select or see two modes at once: 2.4GHz And 5GHzIn some firmware versions, the settings are divided into different tabs, for example, "Wi-Fi 2.4G" and "Wi-Fi 5G." The presence of settings for 5 GHz confirms support for this frequency.
☑️ Check in the web interface
If there is no mention of 5 GHz or standard in the menu 802.11ac/ax, then your router only operates at 2.4 GHz. In this case, you'll need to replace the hardware to expand its functionality.
Using the My Rostelecom mobile app
For users who prefer to manage their internet from their smartphone, the operator has developed a convenient app. My RostelecomThis method is one of the easiest for quick diagnostics. After logging into the app using your contract number or account, select your device from the list of connected devices.
The router card often displays basic information about the model and connection status. Go to the Wi-Fi settings section. If the router supports two bands, the app will offer you the option to manage them separately: you'll be able to see the network names (SSIDs) for each frequency and, if necessary, change passwords or enable/disable wireless broadcasting.
The advantage of the mobile method is that the interface is adapted for beginners and not overloaded with technical jargon. You can immediately see whether the 5G network is active. However, detailed technical parameters, such as channel bandwidth or signal strength, may be hidden.
It's worth noting that the app's functionality is constantly being updated. If you don't find the settings you need, check the app store for updates. Google Play or App Store.
Analyzing available Wi-Fi networks on your device
Another practical method is to view a list of available wireless networks from any device with a Wi-Fi module. Dual-band routers often broadcast two different networks. By default, your ISP may add a prefix to the primary network name. _5G or _5GHz.
If you see two network names in the list that differ only in this ending, there's no doubt: the router is distributing internet on both frequencies. By connecting to a network with a 5G adapter, you'll automatically switch to the high-speed band, provided your device (laptop, phone) also supports this standard.
However, if the router is configured to use a single network name (technology Smart Connect or If you use Band Steering, then only one network will be listed. In this case, the router automatically decides which frequency to connect the client to based on the signal strength and channel load. In this case, the frequency can only be determined through the connection properties on the computer.
⚠️ Please note: Not all older smartphones and laptops can "see" 5 GHz networks. If your phone doesn't show a network ending in _5G, it doesn't always mean your router isn't broadcasting it—there may be a problem with your device's receiver.
Technical differences between the 2.4 GHz and 5 GHz bands
Understanding the difference between frequencies will help you set up your equipment correctly. Range 2.4 GHz is an older and more common method. Its main advantage is its high signal penetration. It penetrates walls and ceilings better, providing coverage in all corners of the apartment, even if the router is located in a distant room.
However, this frequency has a significant drawback: airwave congestion. Not only neighbors' routers operate on 2.4 GHz, but also Bluetooth headsets, microwave ovens, and baby monitors. This creates interference and reduces the actual speed. 5 GHz is freer and provides much higher data transfer rates, but has a shorter range and is less able to penetrate walls.
Below is a comparison table of characteristics to help you make a choice:
| Characteristic | 2.4 GHz band | 5 GHz band |
|---|---|---|
| Maximum speed | Up to 150-300 Mbps | Up to 800+ Mbps |
| Penetration ability | High (good through walls) | Low (walls muffle the signal) |
| Airtime congestion | Very high | Low |
| Range | Up to 50-70 meters | Up to 20-30 meters |
Setting up and separating networks (SSID)
If you find out that your router Rostelecom Since it supports both frequencies but distributes them under the same name, you may need to separate them. This is useful if you want to force your gaming computer to use the fast channel while keeping your smart home sensors on the 2.4 GHz frequency.
To do this, in the web interface, find the setting, which may be called Smart Connect, Band Steering or "Network Aggregation." Disable this feature. After this, separate fields for entering names (SSIDs) for each frequency will become available. Name them clearly, for example, Home_WiFi And Home_WiFi_5G.
Don't forget to save your settings by clicking the button Apply or SaveThe router may reboot. After this, you'll need to reconnect all your devices, selecting the desired network from the list.
What should I do if the internet goes down after splitting networks?
If the internet stops working on your devices after separating networks, try forgetting the network on your device and reconnecting using the password. If that doesn't help, check to see if the main PPPoE or IPoE settings in the WAN section have been reset, although changing the Wi-Fi name usually doesn't affect your ISP connection settings. As a last resort, resetting the router using the Reset button may help.
Frequently Asked Questions (FAQ)
Can a Rostelecom router only operate at 5 GHz?
Theoretically, you can disable the 2.4 GHz band in the settings, leaving only 5 GHz. However, this is not recommended, as many smart home devices (vacuum cleaners, lamps) simply won't detect the network and won't be able to connect.
Why is the 5 GHz speed lower than stated in the tariff?
Speed depends not only on the frequency but also on the router's transmitter power, the quality of the cable connected to the PC, and the router's CPU load. Also, make sure you have a clear line of sight to the device.
Do I need to change my router if it doesn't support 5 GHz?
If you have a tariff plan higher than 100 Mbps and you actively use the Internet on several devices at the same time, replacing it with a dual-band model (AC1200 and above) will significantly improve the situation. For plans up to 50-80 Mbps, an old router may be quite sufficient.
Does router frequency affect ping in games?
Yes, the 5 GHz band typically provides more stable ping and lower latency, as it's less susceptible to interference from neighboring networks and household appliances. This is critical for online gaming.
