How to check devices connected to a Rostelecom router

A slow internet connection or intermittent disconnects are often the first warning signs that someone may have accessed your home network. Control of connected clients — is a basic home network administration skill that allows you to quickly identify "neighborly" traffic or forgotten gadgets consuming bandwidth. In the provider's ecosystem Rostelecom This problem can be solved in several ways, depending on the hardware model and software version.

Modern routers provided by operators have fairly advanced monitoring functionality, but access to it is not always obvious to the average user. Sagemcom, Sercomm, Huawei These brands are most often found in subscribers' homes, and each has its own interface features. Understanding how a local network works will help you not only view a list of devices but also manage access efficiently, ensuring stable video conferencing and online gaming.

In this article, we'll cover all available verification methods in detail: from logging into the web interface through a browser to using specialized mobile apps and the command line. You'll learn how to distinguish your devices from others by MAC addresses, understand the importance of changing default passwords, and discover how to permanently close the door to unwanted visitors. The only way to guarantee that the intruder will be disconnected is to change your Wi-Fi password and encryption type to WPA2/WPA3.

Login to the router admin panel

The first and most reliable step to obtaining complete network information is logging into your router's web interface. This is the "brain center" of your device, storing connection logs and the current status of all ports. First, make sure your device (computer or smartphone) is connected to the Rostelecom router via Wi-Fi or a LAN cable, as remote access from the external network is often blocked by default for security reasons.

Open any modern browser and enter the gateway IP address in the address bar. The standard address for the equipment Rostelecom most often is 192.168.1.1 or 192.168.0.1If these combinations don't work, you need to find the current address through your computer's network card settings. On Windows, this is done using the command ipconfig in the command line, where you need to find the line "Default gateway".

⚠️ Attention: When entering an address, use the browser's address bar, not the Yandex or Google search bar. Otherwise, you'll get a list of websites based on your request, not the router interface.

After navigating to the address, the system will ask for your login and password. If you've never changed these details, they're likely still at the factory settings. For devices Sagemcom And Sercomm the standard pair is often admin / admin or admin / 1234The exact password information is always listed on a sticker located on the bottom of the router. If the default passwords don't work, they may have been changed previously, and a factory reset will be required.

What to do if you have lost your router password?

If you don't remember the password you set previously, the only solution is to perform a hard reset. On the back of the router, locate the recessed hole labeled "Reset." Press it with a paperclip for 10-15 seconds until the LEDs blink. The router will reboot to factory settings, and the password will be reset to the one on the sticker.

Analyzing the list of connected devices in the interface

After successful authorization, the main status information page will open. The interfaces of different Rostelecom router models may look different, but the logic behind the data layout remains similar. You need to find the section responsible for the local network. Look for the tabs with the following names: Local Network, LAN, Home Network or LAN network.

Within this section there is often a subsection DHCP Server or Client List (Client List). This is where a table of all active IP address tenants is displayed. You'll see the IP address, MAC address (the physical address of the network card), and, sometimes, the device name (Hostname). The name can be customized by the user (e.g., iPhone-Alex) or generated automatically by the system.

For ease of comparison, here's an example of a table of connected clients that you can see on the screen:

Please note that the number of rows in the table should correspond to the number of your personal devices. If you count five devices in the list, but you only own a phone and a laptop, it means there are extra connections on the network. MAC address — is a unique identifier that helps distinguish one device from another, even if they have similar names.

Using the My Rostelecom mobile app

For users who find it inconvenient to open a browser and enter IP addresses every time, the company Rostelecom developed an official mobile application My RostelecomThis tool allows you to manage tariffs, services, and, importantly for our topic, control your home network directly from your smartphone. The app is available for platforms Android And iOS.

After installation and authorization using your contract number or phone number, navigate to the section responsible for your home internet. The router management menu (often called "My Router" or "Wi-Fi Management") displays the current network status. Here, you can see a list of connected devices in a more user-friendly format than in the web interface. The app often even displays operating system logos (Apple, Android, Windows), making identification easier.

The app's functionality allows you not only to view the list but also to quickly block access to unwanted users. Simply tap the switch next to the device's name to terminate the connection. However, keep in mind that simply blocking the device through the app may only be temporary if the access password hasn't been changed.

Checking via command line and network utilities

For advanced users who prefer working with code and system commands, there's a way to check connected devices without logging into the router's web interface. This method is based on analyzing the ARP (Address Resolution Protocol) table, which stores the mappings between IP and MAC addresses on your computer's local network.

To use this method, open the command prompt. In Windows, this can be done by searching for cmd or a key combination Win + R and entering the command cmdIn the window that opens, enter the following command:

arp -a

The system will display a list of all devices with which your computer communicated during the current session. You'll see IP addresses and their corresponding physical addresses. This list may be less comprehensive than the router's, as it only shows devices with which it communicated, but it's excellent for quickly diagnosing the presence of rogue MAC addresses in a network segment.

⚠️ Attention: Team arp -a Shows your computer's cache. If a device is online but your PC hasn't yet connected to it, it may not appear in the list. For a more complete picture, it's best to use the router's web interface.

There are also specialized network scanners such as Advanced IP Scanner or Angry IP ScannerThese programs automatically scan the entire address range (for example, from 192.168.1.1 to 192.168.1.254) and generate a detailed report on all active nodes, their manufacturers, and open ports. This is a powerful tool for in-depth diagnostics.

How to identify someone else's device by MAC address

When you see an unknown device in the list, the first thing you need to do is figure out what it is. Names like Unknown or Android-xyz little is said about it. The key to the mystery is MAC address — a hexadecimal string of the form XX:XX:XX:XX:XX:XXThe first three bytes (the first 6 characters) of this address are called the OUI (Organizationally Unique Identifier) ​​and identify the manufacturer of the network equipment.

There are many online services for decoding the OUI. After copying the first six characters of the MAC address from the router's list, you can enter them into a search engine and search for "MAC address vendor lookup." The system will tell you the brand of the device: Samsung, Apple, Espressif (often used in smart plugs and lamps) or Intel (PC network cards). This helps determine whether it's a smartphone, a TV, or some kind of IoT gadget.

You can also conduct a "registration" of your own devices. Go to every Wi-Fi-connected gadget in your home and look up its MAC address in the settings.

• 📱 On Android: Settings → About phone → General information → Wi-Fi MAC address.
• 🍏 On iOS: Settings → General → About → Wi-Fi Address.
• 💻 On Windows: Command Line → ipconfig /all → Physical address.
• 🖥️ On macOS: System Preferences → Network → Wi-Fi → Details → Hardware.

By comparing this data with the list in the router, you can easily identify the “outsider” by the process of elimination.

Blocking strangers and protecting your network

If, after a thorough inspection, you discover a device that doesn't belong to you, you must act immediately. Simply disabling it through the router interface often only provides a temporary solution, as rebooting the router or renewing the DHCP address lease may allow access again. The most effective method is to completely change the security key.

Go to your wireless network settings (WLAN, Wireless, Wi-Fi) in the admin panel. Find the field Pre-Shared Key or PasswordCreate a complex combination containing mixed-case letters, numbers, and special characters. Be sure to check the encryption type: it should be set to WPA2-PSK or WPA3Old protocols WEP or WPA (without the number 2) are considered hacked and do not provide adequate protection.

An additional security measure is MAC address filtering. You can enable the "Allow List" in your router settings. In this mode, the router will only allow devices whose MAC addresses are manually entered into the table to connect to the network. All others, even with the password, will be blocked. This is the most reliable, albeit labor-intensive, method of protecting the network perimeter.

⚠️ Attention: Router interfaces Rostelecom (Sagemcom, Sercomm, Eltex) are periodically updated by the provider. Menu locations and item names may differ from those described in the instructions. If you cannot find the desired setting, check the latest documentation on the official support portal or in your personal account.

After changing your password, all your devices will be disabled. You'll have to re-enter the new password on every smartphone, tablet, and TV. This is a small price to pay for the security of knowing your connection is yours alone. Regularly monitoring your client list and keeping your router firmware up to date are the keys to a stable and fast internet connection.

Why does the router show more devices than I can see?

This can happen for several reasons. First, many modern gadgets (smartphones, tablets) create two connections when connected: one for data transfer and one for business or guest network use. Second, the list may include "smart" devices such as light bulbs, outlets, and vacuum cleaners running in the background. Third, some old entries in the DHCP table may not disappear immediately after the device is disconnected until the address lease expires.

Can a neighbor steal my internet if I don't see him on the list?

If the device doesn't appear in the DHCP Client List and isn't consuming traffic in the statistics, it's likely unavailable. However, theoretically, a skilled attacker could try to hide their presence (MAC spoofing), but this is rare on a home network. If the internet speed is normal and the device list is clean, there's no reason to panic.

What is a device named "Unknown" or "Android-..."?

The device name is set either by the manufacturer or by the user in the settings. If the name is "Unknown," it means the device doesn't report its network name when connecting. This is often the case with IoT devices (sensors, cameras) or Linux-based devices. The "Android-..." prefix usually indicates a phone or tablet, but the exact model can only be determined by the MAC address.

Do I need to change my Wi-Fi password if I just changed my router?

Yes, this is a good security practice. On new routers issued RostelecomThe Wi-Fi password is often printed on a sticker and is standard across all devices. Attackers can know these standard passwords. Setting a unique password when first setting up new equipment significantly increases security.
