In today's digital world, a home Wi-Fi network has become the control center for all gadgets, from smartphones to smart refrigerators. However, situations often arise when it's necessary to restrict internet access for a specific device. This may be due to parents wanting to limit their children's tablet time, the need to free up bandwidth for work, or even a simple suspicion that an unauthorized user has connected to your network. Rostelecom, being one of the largest providers, provides equipment with wide customization options, but not all users know how to use them.
There are several ways to solve the problem of disconnecting a subscriber, and the choice of method depends on whether you have physical access to the client device itself or you manage the network remotely. Routers Different models (Sagemcom, Huawei, ZTE, Eltex), often provided by providers, have their own interface features, but the general operating principle remains similar. In this article, we'll cover all available options in detail, from a simple password change to professional MAC address blocking.
Before taking any drastic action, it's important to understand the difference between temporarily disabling and completely blocking access. If you simply want to reboot your device or fix a temporary connection issue, pressing the Wi-Fi disable button on the device itself will suffice. However, if your goal is security and traffic control, you'll need to access your router settings. Only MAC address blocking ensures that the device cannot connect again without your knowledge, even if it knows the password.
Using the official My Rostelecom app
The easiest and most accessible way to manage a home network for the average user is a mobile application. My RostelecomThis tool allows you to control connected devices directly from your smartphone screen, without requiring in-depth technical knowledge. The app's interface is simplified and optimized for quick interaction.
To get started, log in to the app using your personal account information or the phone number linked to your account. Once logged in, go to the section responsible for managing your internet or Wi-Fi. There, you'll see a list of all active clients on your network. They're typically displayed by model name or any names you may have previously assigned to them.
To disable an unwanted device, find it in the list and click the corresponding button or switch. The system may offer two options: temporarily suspend access or permanently block the device. By choosing the block option, you make changes to the router settings remotely via the provider's cloud service.
It's worth noting that the app's functionality may vary depending on your router model. Some older router models may not support full cloud management, requiring local login. In this case, the app will prompt you to access advanced settings or use the web interface.
Login to the Rostelecom router web interface
If you don't have a mobile app at hand or it doesn't provide the functionality you need, the only reliable solution is to access the router control panel through a browser. This method is universal and works for all router models, whether Sagemcom, Huawei or ZTE.
First, make sure your device (computer or phone) is connected to the router whose settings you want to access. Open any browser and enter the gateway's IP address in the address bar. The default address for Rostelecom equipment is usually 192.168.1.1 or 192.168.0.1The exact address is also indicated on the sticker on the bottom of the router.
After entering the address, the system will request a login and password for authorization. By default, this information is also located on the factory sticker and is often a combination admin / admin or admin and a unique code. If you've previously changed this information and forgotten it, you'll need to reset your router to factory settings.
⚠️ Attention: If you changed the password for entering the router settings and do not remember it, reset it using the button Reset will restore factory settings, but will also reset the internet connection settings (PPPoE, VLAN), which will need to be re-entered.
After successful authorization, you'll be taken to the main page of the control panel. The interface may look different depending on the firmware version, but the menu structure is generally the same. Find the section related to wireless networking or WLAN.
Blocking devices via MAC filter
The most reliable technical method for disabling a device is to use MAC address filtering. MAC address — is a unique network interface identifier assigned by the manufacturer and unchanged (with rare exceptions). This method allows you to create a "blacklist" of devices that are strictly prohibited from accessing the network.
In the router's web interface, find the section WLAN or Wireless network, and then subsection MAC filter or Address filteringHere you'll need to enable the filtering function and select the "Deny" or "Blacklist" mode. Once enabled, you'll need to add the MAC address of the device you want to disable.
To find out the MAC address of a connected device, you can use the section Status or Client list (Client List) in the router. All active connections are displayed there. Copy the address of the desired device and add it to the filtering rules. After saving the settings, the device will lose connection to the router, even if it tries to reconnect.
☑️ Check before blocking
Filtering works at the hardware level and does not depend on whether the user knows the Wi-Fi password or not.
Below is a table with sample paths to MAC filter settings for popular router models commonly found among ISP subscribers:
| Router model | Menu section | Subsection | Function name |
|---|---|---|---|
| Sagemcom F.AST | Home Network | WLAN | MAC Filter |
| Huawei HG8245 | WLAN | WLAN MAC Filter | Add New |
| ZTE F660 | Network | WLAN | MAC Filter Configuration |
| Eltex NTU-RG-1421G | Wi-Fi | Filtration | Add a rule |
Changing the password and hiding the network SSID
If your goal isn't just to disable a single device, but to completely secure your network from unauthorized access, the most effective method is to change the password. This will forcefully disconnect all connected clients, and only those with the new security key will be able to log in again.
To change the password, go to your wireless network settings (WLAN Security or Security). Find the field Pre-Shared Key or PasswordCreate a complex combination using mixed-case letters and numbers. After saving the settings, the router will restart the wireless module, and all devices will be disconnected.
An additional security measure is to hide the network name (SSID). If you enable the "Hide SSID" feature, your network will no longer appear in the list of available connections on your neighbors' phones and laptops. To connect, you'll have to manually enter the network name and password on each new device.
Why is hiding the SSID not enough?
Hiding the network name isn't complete protection. Specialized programs easily detect hidden networks because devices constantly send connection requests to them. This is more of a protection against "accidental" connections than against hackers.
Combining these two methods—a complex password and a hidden SSID—creates a significant barrier to unauthorized access. However, it's worth keeping in mind that hiding the network may cause some inconvenience when connecting guest devices, as the data entry process will have to be performed manually.
Disabling the device on the client side
Sometimes, a situation requires a reverse approach: you need to disconnect your device from the Rostelecom WiFi network, for example, to force a switch to mobile data or troubleshoot connection issues. In this case, you don't need to change the router settings; all actions are performed on the device itself.
On smartphones running Android or iOS Simply open Settings, go to the Wi-Fi section, tap your network name, and select "Forget this network" or "Disconnect." This will delete your saved connection data.
On computers with an operating system Windows You can use the command line for more granular control. For example, to delete a network profile, you can use the command:
netsh wlan delete profile name="Your_Network_Name"Many routers and operating systems also have a "Guest Network" feature. If you want to temporarily grant someone access without sharing your main network with your personal files, it's best to activate guest mode. It often has a timer that automatically turns off devices after a set amount of time.
Diagnosing and troubleshooting connection problems
There are cases when a device cannot be disconnected using standard methods, or it constantly tries to reconnect, creating a load on the channel. This may indicate a software glitch in the router or a virus on the connected computer.
In such situations, it's recommended to perform a hard reset. Unplug the router for 10-15 seconds, then plug it back in. This will clear the device's RAM and reset any temporary routing table errors.
If the problem persists, check the router logs. In the section System Log or Magazine You can view the connection history and access attempts. This will help you understand whether the problem is technical or whether someone is persistently trying to hack your network.
⚠️ Please note: Router interfaces and mobile apps are constantly being updated. Button locations and menu item names may differ from those described in the instructions. Always check the latest documentation on the official website of your equipment manufacturer.
Maintaining control over connected devices is an essential skill for any modern user. Regularly checking your client list and knowing how to block them will help you maintain high internet speeds and secure your personal data.
Frequently Asked Questions (FAQ)

Without the administrator password, you won't be able to access the router settings. However, if you have physical access to the router, you can reset it to factory settings using the button. Reset, after which the login will be carried out using the data from the sticker on the bottom of the device.
Will the user see that they have been disconnected from WiFi?
They won't receive a direct notification. However, their device will lose internet connection, and your router may appear as "Connected, no internet access" in the list of available networks, or the device will repeatedly try to reconnect without success.
Will the blocking be reset after rebooting the router?
No, all settings, including MAC filters and changed passwords, are saved in the router's non-volatile memory. They will remain active even after a power outage until you change them back.
How to find the MAC address of someone else's phone?
It's difficult to find out the exact MAC address of another device without access to it due to privacy features in modern operating systems. However, the router's client list (Status or Client List section) displays the MAC addresses of all connected devices, allowing you to block them.
