Modern home network operating conditions dictate their own requirements for connection speed and stability. Many users of equipment from Rostelecom They encounter a situation where the standard 2.4 GHz band can no longer handle the load due to noise pollution from neighboring access points. In this case, the only viable solution is to switch to the clearer and faster 5 GHz band.
Changing the frequency range doesn't require in-depth knowledge of networking technologies, but it does require careful adjustments. In this article, we'll cover in detail how to enable high-frequency operation, the limitations of the equipment, and why separating networks is often a more practical option for multi-story buildings.
It is important to understandPlease note that not all ISP devices support 5 GHz. Before setting up, make sure your router is a dual-band model. If the device only supports one frequency, you won't be able to activate the second one through software, as this is a hardware limitation.
Features of the 2.4 and 5 GHz frequency ranges
Choosing the right frequency directly impacts the quality of data transmission in your apartment. Range 2.4 GHz It's the most widely used and compatible with all gadgets released in the last 15 years. Its main advantage is excellent signal penetration through walls and ceilings, allowing Wi-Fi coverage even in remote rooms.
However, this frequency has a significant drawback: a narrow channel and heavy congestion. In apartment buildings, dozens of neighboring routers create a "mess" of signals, leading to a drop in speed and increased ping. This is where the range comes into play. 5 GHz, which offers significantly more free channels and a theoretical data transfer rate several times higher than that of its younger brother.
⚠️ Attention: The 5 GHz signal has a shorter range and penetrates concrete walls less effectively. If you live in a large apartment or a house with thick partitions, the coverage range at the higher frequency may be significantly reduced.For a clear comparison of characteristics, we'll look at the key parameters of both ranges in the table below. This will help you decide which operating mode will be the most suitable for your needs.

Before messing with the interface settings, you need to physically verify that your equipment is capable of handling high frequencies. Typically, router models issued Rostelecom, have a marking or name indicating support for the standard 802.11ac or Wi-Fi 5/6If the device's body or documentation only lists the 802.11n standard, it's likely a single-channel model.
Look at the sticker on the bottom of your router. If there are two default SSIDs (network names), for example,
RT-WiFiAndRT-WiFi-5G, then your device is definitely dual-band. Also, the presence of antennas marked dBi and 1 Gbps LAN ports often correlate with the presence of a 5 GHz module, although it is not a guaranteed indicator.The most reliable way is to log in to the web interface. Enter the gateway IP address (usually
192.168.1.1or192.168.0.1) in the browser's address bar. After entering your username and password (indicated on the sticker), go to the wireless network section. If you see tabs or menu items labeled "2.4G" and "5G," the functionality is available.What should I do if there is no 5 GHz option in the menu?
If you're sure your router is dual-band but don't see the option, it may be hidden in the advanced settings or disabled remotely by your ISP. Try updating the device's firmware via the "System Tools" menu or contact technical support to unlock the functionality.
Login to the router control panel
To make changes to your wireless network configuration, you'll need access to the administrative panel. Connect your computer or smartphone to the router via a LAN cable or your current Wi-Fi network. Open any browser and enter the gateway address in the address bar. For equipment Sagemcom, Eltex or Huawei, used by the provider, this is most often
192.168.1.1.The system will request authorization data. Standard credentials are usually printed on a label under the device's casing. The login is often important.
admin, and the password is a string of letters and numbers. If you previously changed the login password and forgot it, you'll need to perform a factory reset, which will require you to reconfigure the PPPoE connection.After successfully logging in, you'll be taken to the main status page. The interface may differ depending on the model, but the menu structure is the same. You need to find the section responsible for wireless connections. It may be called
WLAN,Wireless,Wi-FiorWireless network.Activating and configuring the 5 GHz band
Once you find the Wi-Fi settings section, you'll see switches or separate tabs for frequencies. Modern interfaces often implement this feature. Smart Connect or "Band Aggregation," which creates a single network with a shared name, automatically distributing clients. However, for manual control, it's best to disable this feature.
Separate your networks by assigning them unique names (SSIDs). For example, call your main network
Home_WiFi, and high-speed -Home_WiFi_5GThis will allow you to manually select which frequency a specific device connects to. In the 5 GHz band settings, make sure "Enable Wireless" is checked.Pay special attention to the choice of channel and channel width. For the 5 GHz band, the optimal width is
80 MHz, which will ensure maximum throughput. It is better to set the operating mode (Mode) to 802.11ac mixed or ax mixed, if your router supports the new Wi-Fi 6 standard.☑️ 5 GHz setup
Completed: 0 / 6Separating network names (SSID) for stability
Many users prefer to maintain a single network name for both bands, relying on the router's automatic switching. However, experience shows that these algorithms often perform incorrectly: a smartphone may "catch" on a weak 2.4 GHz signal when located two meters away from the router, instead of switching to the faster 5 GHz.
Network name sharing (SSID) gives you complete control. You can connect your TV, console, and gaming laptop to the network. 5G, providing them with maximum speed for 4K streaming and online gaming. Meanwhile, smart lamps, vacuum cleaners, and older gadgets will remain online. 2.4G, where they feel more comfortable.
To implement this method, enter different names in the settings for each frequency tab. For example, add the suffix "_5G" to the primary network name. After saving the settings, the router will restart the wireless modules. Two new networks will appear on your devices, which you'll need to connect to using the same password (for convenience, they can be the same).
⚠️ Attention: After changing the network name or password, all your devices will lose connection. You'll need to reconnect on each device, selecting the new network from the list of available ones.Typical problems and solutions
Users may encounter a number of difficulties during the setup process. It often happens that after enabling the 5 GHz band, devices simply don't see the new network. This may be due to the device's network adapter only operating in the standard. 802.11n and does not physically support the 5 GHz frequency. Check the specifications of your laptop or smartphone.
Another common issue is unstable operation or low speed even at 5 GHz. In this case, it's worth experimenting with the channel selection. If the "Auto" mode is selected, try locking a specific channel (for example, 36, 40, or 44), as automatic selection sometimes leads to conflicts with radars or neighboring equipment.
It's also worth keeping regional restrictions in mind. Some routers, especially those imported from abroad or flashed, may have restrictions on certain channels depending on the selected region. Make sure your country or region is set to "Russia/Europe" in your system settings.
Optimizing Wireless Network Security
Switching to a new band is a great opportunity to review your security policy. Make sure both bands are using modern encryption. WPA2-PSK or WPA3, if your equipment allows it. Using the outdated WPA or WEP protocol makes your network vulnerable to hacking in minutes.
Your passphrase should be complex and contain mixed-case letters, numbers, and special characters. Avoid simple combinations like your date of birth or phone number. A strong password will protect you not only from traffic theft but also from hackers using your network for illegal activities.
An additional security measure may be to disable the function.
WPSDespite the convenience of connecting with just one click, this protocol has known vulnerabilities. In the security settings, find the WPS option and set it to "Disable."Is it possible to disable the 2.4GHz band completely?
Yes, it's technically possible. In the 2.4G WLAN settings, simply uncheck "Enable." However, you should only do this if you're sure all your devices (including your smart home) support 5 GHz. Otherwise, some gadgets will simply stop working.
Why does the 5 GHz speed drop the further I move from the router?
This is a physical property of high-frequency signals. 5 GHz waves have a shorter wavelength and attenuate more quickly when passing through obstacles. For larger areas, mesh systems or repeaters that support dual-band operation are recommended.
Do I need to reconfigure my router after updating the firmware?
Typically, the settings are saved. However, if you notice strange network behavior after the update or the 5 GHz settings are missing, we recommend performing a factory reset and reconfiguring the router to eliminate software conflicts.
Does changing the range affect the Rostelecom tariff?
No, the Wi-Fi frequency is an internal setting of your local equipment. It doesn't affect the speed provided by your cable provider and doesn't require a change to your data plan. You're simply using the available bandwidth more efficiently.
