Modern Rostelecom routers, operating in dual frequency bands, by default combine 2.4 and 5 GHz networks under a single name. This technology, known as Smart Connect, is designed to simplify the user's experience by automatically selecting the optimal frequency for each connected device. However, in practice, the algorithms often make mistakes, causing fast devices to operate on a slower frequency, and older devices to lose connection.
Splitting these frequencies into two different network names (SSIDs) allows you to manually manage the connection. You can direct your laptop or TV to the high-speed 5 GHz band, while keeping smart bulbs and vacuum cleaners on the stable 2.4 GHz band. This is especially useful if you have devices in your home that simply don't see the network or operate intermittently due to automatic switching.
In this article, we'll detail how to disable Smart Connect and set unique names for each band on popular router models from Sagemcom, Eltex, Sercomm, and Huawei, which providers provide to their subscribers. The setup process requires careful attention, but the results are worth it—you'll gain complete control over your home internet.
Why is Wi-Fi frequency separation necessary?
The main reason why users seek split rangesThe problem stems from the incompatibility of older devices with new standards. Many smart home gadgets, such as plugs, sensors, and budget cameras, operate exclusively in the 2.4 GHz band. When the router broadcasts a single network name, these devices may attempt to connect to the 5 GHz band, lose the signal, and enter a constant network search mode, which puts a strain on the router's processor.
Furthermore, splitting the band prevents your powerful smartphone or laptop from becoming stuck on the congested 2.4 GHz band while 5 GHz is freely available nearby. The 2.4 GHz band is often clogged with neighbors' signals, Bluetooth devices, and microwaves, which reduces the actual internet speed. Forced connection to 5 GHz provides maximum speed, especially in apartment buildings.
⚠️ Note: After separating networks, you will need to manually reconnect all devices in your home to the new network names. Make sure you remember your passwords, as they may be reset when changing security settings.
It's also worth noting that some games and high-definition streaming apps require a stable channel without frequency hops. The Smart Connect feature can sometimes cause micro-interactions when switching, which is critical for online gamers. By separating the networks, you create static environment, where each device knows its own path.
Preparing to set up a Rostelecom router
Before making any changes to the hardware configuration, you must access the administrator's web interface. To do this, your device (computer or phone) must be connected to the router. A cable connection is preferred. Ethernet, as it ensures there are no interruptions during setup, but your current Wi-Fi connection will work as well.
Open any browser and enter your router's IP address in the address bar. Rostelecom equipment most often uses addresses 192.168.1.1 or 192.168.0.1The exact address, as well as the login and password, are usually found on a sticker on the bottom of the device. Standard credentials often look like admin/admin or superadmin/superadmin.
If you've changed your interface password before and forgot it, you'll need to perform a factory reset (hard reset). To do this, find the recessed button. Reset On the case, press it with a paperclip and hold it for about 10-15 seconds until the indicators blink simultaneously. After this, the router will reboot with factory settings.
☑️ Preparing for setup
Setting up Sagemcom Fast 2804 and 3804
Sagemcom routers are among the most common devices in Rostelecom networks. The interface of these models may differ depending on the firmware version, but the logic remains similar. After logging in, you need to find the tab responsible for the wireless network. This is usually called Network -> WLAN or simply Wi-Fi.
In the WLAN settings menu, find the item Basic or Basic settingsHere you will see a switch or checkbox that controls whether the ranges are merged. It may be called 2.4G/5G Integration or Smart ConnectYou need to uncheck this box or move the switch to the position Disable (Disable).
After disabling integration, the fields for entering network names (SSIDs) separately for 2.4 GHz and 5 GHz will become active. Enter the desired names, for example, MyHome_24 And MyHome_5G. Don't forget to check your security settings as well (Security) to ensure that both frequencies have a modern encryption protocol installed. WPA2-PSK or WPA3.
What if the menu is in English?
If the router interface is entirely in English and you don't speak it, use the built-in translator in Google Chrome. Right-click anywhere on the page and select "Translate to Russian." This will help you navigate the menu options, although some technical terms may not be translated.
After making all the changes, be sure to click the button Apply or Save at the bottom of the page. Your router may require a reboot for the new settings to apply. If the connection is lost, find the new names in the list of available networks and connect to them using the password you set.
Instructions for Eltex and Sercomm routers
Equipment from Eltex and Sercomm often has a more modern and user-friendly interface, sometimes with support for the Rostelecom WiFi mobile app. However, for in-depth frequency separation customization, it's better to use the web interface. Go to WLAN or Wireless network.
Unlike Sagemcom, here separation can be implemented by creating separate profiles or virtual access points (SSIDs). Find the settings Radio (Radio). You'll see two independent settings blocks: one for 2.4 GHz and one for 5 GHz. Make sure both radio modules are enabled.
Each of the blocks will have a field SSID Name. Give them unique names. Also pay attention to the parameter Channel Width (Channel width). For 2.4 GHz, it is recommended to set 20 MHz for stability in apartment buildings, and for 5 GHz you can safely choose 40 or 80 MHz for maximum speed.
| Parameter | Recommendation for 2.4 GHz | Recommendation for 5 GHz |
|---|---|---|
| Channel width | 20 MHz | 40 / 80 MHz |
| Channel | 1, 6 or 11 | Auto or 36-64 |
| Signal strength | High | High |
| Security protocol | WPA2-PSK | WPA2/WPA3 Mixed |
After saving the settings, the router will apply them within a few seconds.
Huawei and ZTE setup features
Huawei and ZTE routers provided by carriers often have a simplified interface. To access all the necessary features, you may need to switch the display mode to "Advanced" or "Professional." Look for this button in the upper-right corner of the screen or in the bottom menu.
Go to the section Wi-Fi -> Basic settingsHere you can find the option 5G priority or Combine 2.4G and 5GYou need to disable network merging. If this option isn't checked, your model separates networks by default, and you just need to enter different names in the fields. Network name (2.4G) And Network name (5G).
Huawei devices often feature Wi-Fi+, which automatically switches devices between Wi-Fi and mobile data depending on signal strength. For stable smart home operation, it's best to disable this feature in the Wi-Fi settings to prevent devices from "jumping" between networks.
⚠️ Note: Firmware interfaces can be updated remotely by the operator. If you don't see the steps described, check the latest instructions for your specific model on the official support portal or in your subscriber account.
After changing network names, all devices will lose connection. This is normal behavior. You'll need to go to each device, select a new network name (for example, one with "5G" added), and enter the password. Old network profiles can be deleted in the Wi-Fi settings on your phones to prevent them from trying to connect to the now-defunct shared name.
Troubleshooting and diagnostics
After splitting the frequencies, you may encounter a situation where some devices no longer detect the 5 GHz network. This may be because the device doesn't support this standard or is too far from the router. The 5 GHz signal penetrates walls less effectively, so distant rooms may only receive 2.4 GHz.
If your internet speed hasn't improved after connecting to 5 GHz, check if your router's Bandwidth Control settings are set to a speed limit or if you've selected a congested channel. Use Wi-Fi analyzer apps on your smartphone to find a free channel and manually enter it in the router settings section. Channel.
Another common issue is the device becoming stuck at low speeds. Even if you're connected to 5 GHz, the router may artificially limit the speed due to packet errors. In this case, a full reboot can help: unplug the router for 1 minute, then plug it back in. This will clear the memory buffer and reset any temporary errors.
Frequently Asked Questions (FAQ)
Does network partitioning affect internet speed?
Name separation alone doesn't increase the speed of your ISP's connection. However, it allows your devices to operate at their maximum speed, eliminating situations where a fast device connects to the slow 2.4 GHz band due to a router algorithm error.
Do I need to change the password when separating networks?
Technically, no, you can keep the password the same. However, the security system may require you to re-enter the password for the "new" network, even if the characters remain the same. For maximum security, it is recommended to use complex passwords with a combination of letters and numbers.
What should I do if my old TV can't see the 5 GHz network?
Many older Smart TVs don't support the 5 GHz frequency. In this case, you'll need to connect the TV to the network with the same name you assigned to the 2.4 GHz band. This is precisely why you need to separate the networks—to clearly understand where each device connects.
Can frequency splitting degrade Wi-Fi coverage?
No, the physical signal strength and coverage remain the same. Only the logical network name changes. However, it's worth remembering that the 5 GHz frequency inherently has a shorter range and penetrates obstacles less effectively than 2.4 GHz, regardless of the network name settings.
How to get everything back if something goes wrong?
You can always go back to your router settings and enable Smart Connect (network aggregation) or simply set the same SSID for both bands. In extreme cases, the reset button on the device will help.
