A modern home is filled with smart devices that require a constant internet connection, but it's not always a good idea to share your main network with all guests. Creating an isolated Wi-Fi segment allows you to protect your personal files, printers, and security cameras from unauthorized access. On routers provided by your provider Rostelecom, this function is implemented quite flexibly and does not require deep knowledge in the field of network technologies.
In this article, we'll discuss how to properly activate and configure a guest profile to balance convenience for your friends and the security of your digital environment. You'll learn about the differences in interfaces across different hardware models and understand which encryption settings to choose for maximum protection.
Traffic segregation isn't just a whim, but a necessary element of cyber hygiene, especially if you frequently have people using untested devices. Let's take a detailed, step-by-step look at the process of creating such a network.
Why is it necessary to separate a home network?
The main reason for creating a separate access point is security. When a guest connects to your main Wi-Fi, they are technically connected to the same local network as your computers. This means potential access to shared folders, network printers, and even the router's management interface if the admin passwords are weak or default.
Isolation also helps manage bandwidth. If guests start actively downloading content or watching 4K videos, your main workflow or online gaming shouldn't suffer from a lack of speed. Guest network allows you to set speed limits or simply separate this traffic so that it does not interfere with critical tasks.
Another aspect is privacy. In guest mode, devices are invisible to each other, eliminating the possibility of accidentally or intentionally scanning your devices' ports by connected smartphones. This is especially important if you have devices at home. smart home, which may have software vulnerabilities.
⚠️ Attention: On some older router models Sercomm or D-Link Guest mode may be absent or malfunction on earlier models when using both the 2.4 GHz and 5 GHz bands simultaneously. Always check the specifications for your specific model on the manufacturer's official website.Preparing for equipment setup
Before making any configuration changes, ensure you have access to the router's web interface. To do this, connect your computer or smartphone to the main Rostelecom network via cable or Wi-Fi. Make sure the device has automatically received an IP address and can access the gateway.
You'll need your control panel login information. It's usually located on a sticker on the bottom of the device, but if you've changed it before, use the current login and password. The login address most often looks like this:
192.168.1.1or192.168.0.1.It's also worth deciding on a name for the new network (SSID) and a strong password in advance. Using simple combinations like "12345678" will negate all security efforts. It's recommended to use a password generator or create a long, random phrase.

Find the section responsible for wireless networks. It may be called "Wi-Fi," "Wireless," or "Wireless."
Creating and configuring a guest profile
In the wireless network menu, find the tab or subsection labeled "Guest Network," "Guest SSID," or "Guest Network." Enable this mode by checking the corresponding checkbox or toggle. Now you need to configure the settings.
Create a network name (SSID) that will be understandable to guests, for example, "Home_Guest". Choose an encryption method. It is highly recommended to use WPA2-PSK or WPA3, if your equipment supports this standard. Avoid legacy WEP or open access.
Set a complex password. Some routers Rostelecom You can set a schedule for the guest network. This is a useful feature: you can set up automatic shutdown of guest Wi-Fi at night or when you're away.
☑️ Configuring guest network security
Completed: 0 / 5After entering all the parameters, be sure to click "Save" or "Apply." The router may reboot the wireless module, and the connection may be momentarily interrupted. This is normal system behavior.
Encryption Parameters and Compatibility Table
Selecting the right security type is critical to ensuring guest device compatibility and data protection. Below is a table to help you choose the right settings.
Encryption type Security level Compatibility Recommendation Open (No) Absent All devices Not recommended WEP Very low Old gadgets Forbidden WPA2-PSK (AES) High Almost everything Recommended WPA3-SAE Maximum New devices For modern gadgets Please note that selecting mixed security mode (WPA/WPA2) may reduce overall network performance, as the router is forced to process packets using different methods. It is better to use pure WPA2 or WPA3.
Access restriction and filtering
Many users don't realize that guest networks can not only be isolated but also speed-limited. This is possible in advanced router settings. Rostelecom (especially the series Eltx) there is a QoS or bandwidth limitation feature for the guest SSID.
You can set a connection limit, for example, 10 Mbps. This is sufficient for messaging and browsing the news, but not enough for downloading large files, which will protect your main connection from overload. MAC address filtering is also available if you want to allow only specific people.
⚠️ Attention: The "Client Isolation" feature prevents guest devices from seeing each other within a guest network. This is useful in public spaces, but at home it can be disruptive if guests want to AirDrop photos or play a game over a local network.The impact of a guest network on the speed of the main channel
Creating a guest profile in itself doesn't reduce speed. However, if many devices connect to the network, they will share the radio channel. On the 2.4 GHz frequency, this can lead to increased latency (ping).
Common problems and their solutions
Sometimes, after setting up the device, it doesn't detect the new network. Make sure you saved the settings and the router has applied them. Try rebooting the device completely via the menu or the power button. Also, check if the SSID is hidden (the "Hide network name" option).
If guests complain about low speeds, check if there's a limitation in the QoS settings. It's also possible that the guest network only operates in the 2.4 GHz band, which is more heavily used by neighboring networks. You can try changing the channel in the settings to a less crowded one (1, 6, or 11).
In rare cases, a router software failure Sercomm or D-Link may be blocking the creation of a second SSID. In this case, updating the firmware to the latest version from the manufacturer's official website or the provider's support portal may help.
Is it possible to create multiple guest networks?
Most home routers Rostelecom Only one guest network is allowed. However, if the model supports split 2.4 GHz and 5 GHz bands, you can create guest profiles for each band separately, effectively creating two networks with different names.
Will guests be able to see my files on my computer?
No, if the guest network feature is implemented correctly. It creates virtual isolation (VLAN or similar) that prevents access from the guest segment to the main (LAN) segment. Your network folders and printers will remain invisible.
How to delete a guest network?
To do this, go back to the Wi-Fi settings, find the Guest Network section, and uncheck "Enable." Don't forget to click the Save Settings button, otherwise the network will continue to work.
