Slow internet speeds or sudden outages on a home network often leave users perplexed. In most cases, the cause isn't a faulty provider's equipment, but rather simple channel congestion from other devices. If you suspect that neighbors or passersby are using your Wi-Fi channel, you should immediately check the list of connected clients. Rostelecom provides standard network diagnostic tools accessible through any browser or mobile app.
Understanding that, How to see who's using Rostelecom's Wi-Fi, is a basic skill for administering a home network. Modern routers provided by the provider, whether models Sagemcom, Sercomm or Eltex, have a built-in mechanism for tracking active sessions. This allows you to see in real time the MAC addresses and IP addresses of all devices currently consuming traffic. Ignoring this issue can lead not only to slow internet but also to the theft of personal data if your network lacks reliable encryption.
In this article, we'll detail the steps to identify uninvited guests. You'll learn how to distinguish legitimate devices from unauthorized smartphones and understand what security measures to take. The only way to reliably disable an intruder is to change the Wi-Fi password and encryption type to WPA2/WPA3., since simple blocking by MAC address often turns out to be a temporary measure due to the possibility of ID spoofing.
Analysis of indicators and indirect signs of hacking
Before delving into complex router settings, it's worth paying attention to the equipment's behavior. There are several telltale signs that someone has connected to your access point. A blinking indicator light is often the first warning sign. Wi-Fi on the router body, even when all your devices are turned off or in sleep mode. Active data transfer is always accompanied by a characteristic rhythmic flashing of the LED.
It's also worth paying attention to your internet speed. If you notice high-definition video content buffering or pages taking longer to load than usual, this may indicate a low bandwidth connection. This is especially noticeable in the evening, when network load is already high. However, if the problem also occurs in the morning, when neighbors are usually asleep, the risk of unauthorized access increases.
For primary diagnostics, you can use specialized mobile scanner applications, such as Fing or Wi-Fi AnalyzerThey allow you to quickly scan the airwaves and display a list of all devices on the local network without logging into the admin panel. This is a quick way to get an initial picture of what's happening, although deeper security configuration still requires access to the router's web interface.
⚠️ Important: A blinking Wi-Fi indicator does not always indicate a hack. Background operating system updates, cloud storage synchronization, or smart devices (cameras, speakers) also cause active data exchange. Always double-check the data through the router interface.
Login to the Rostelecom router web interface
The primary method for monitoring your network is by logging into your router's control panel. To do this, you'll need a device (smartphone, tablet, or laptop) connected to your network via Wi-Fi or cable. Open any browser and enter the gateway's IP address in the address bar. By default, Rostelecom equipment most often uses the following addresses: 192.168.0.1 or 192.168.1.1The exact address is often indicated on a sticker on the bottom of the device.
The system will ask for authorization. The standard credentials are also located on the factory sticker and usually look like this: admin/admin or admin/1234If you previously changed the password for logging into the router settings and forgot it, you will need to reset the device to factory settings using the button ResetPlease be prepared to reconfigure your ISP connection settings (PPPoE, VLAN, etc.) after the reset if they are not transferred automatically.
Interfaces may vary between router models. Devices Sagemcom often have a simplified "Home Network" interface, while Sercomm And Eltex offer more detailed menus. Navigation is usually located at the top or left. You need to find the section related to the wireless network or connection status. In some firmware versions, this section is called "Status."
What to do if the default password doesn't work?
If the admin/admin password doesn't work and you haven't changed it, your provider may have updated the firmware remotely. Try the data on the sticker. If that doesn't work, the only solution is to perform a full reset using the button on the device for 10-15 seconds.
Where can I find a list of connected devices?
After successful authorization, the main menu will open. The menu structure varies depending on the model, but the logic remains the same. You need to find the tab responsible for the local network. It may be called LAN, Local Network or Home networkWithin this section, look for the "Client List," "DHCP Client List," or "Wireless Status" subsection. This is where a table of all active connections is displayed.
In the list that opens, you will see several columns with technical information. The main parameters are IP address, MAC address and sometimes the device name (Hostname). The MAC address is a unique identifier of a network interface, which consists of six pairs of hexadecimal numbers (for example, A1:B2:C3:D4:E5:F6). This is the most accurate way to identify a device, since the IP address can change dynamically.
Modern Rostelecom routers can often identify the device type and display its icon (phone, laptop, TV). This significantly simplifies the process. However, if you see a device with the name "Unknown" or a strange set of characters, be wary. Compare the number of devices in the list with the actual number of gadgets in your home. Don't forget to check the wired connections (LAN) if you have desktop PCs or consoles connected to the router.
☑️ Checking the list of devices
Identifying devices by MAC address
The most reliable way to distinguish your device from someone else's is to check the MAC address. Each network adapter has a unique serial number. To find the MAC address of your Android smartphone, go to Settings → About phone → General informationOn iPhone, this information is located in Settings → General → AboutFor Windows PCs, the command can be run via the command line by entering ipconfig /all.
Create a table of device addresses. This will help you quickly navigate the connection list in the future. If you see an address in the router's client list that isn't in your table and doesn't match any of your devices, your network is being used by third parties. Pay special attention to devices that appear as wired (Ethernet) if you haven't connected your computers via cable.
Below is a sample spreadsheet for keeping track of your devices. Filling it out will take a few minutes, but it will save you time in the future.
tr>
| Device | Owner | MAC address (example) | Connection type |
|---|---|---|---|
| iPhone 13 | Owner | A4:5E:60:12:34:56 | Wi-Fi 5 GHz |
| Asus laptop | Spouse) | B8:27:EB:98:76:54 | Wi-Fi 2.4 GHz |
| Smart TV Samsung | General | 00:1A:2B:3C:4D:5E | Wi-Fi 5 GHz |
| Unknown | ? | C2:4F:11:AA:BB:CC | Wi-Fi 2.4 GHz |
If you discover an unknown device, don't panic. First, try disabling Wi-Fi on all your devices one by one and watch for the entries to disappear from the router's list. This will allow you to accurately match MAC addresses to specific devices. Sometimes "unknown" devices include smart plugs, vacuum cleaners, or lamps, which have simple network modules without fancy names.
Rostelecom.Key mobile app
For users who don't want to navigate the web interface, the operator offers an alternative – a mobile app. Rostelecom.Key (formerly "My Rostelecom"). This is a convenient tool for managing your home network directly from your phone. The app automatically detects your router model and offers a simplified management interface. Functionality may vary depending on your router model.
In the app, the "My Network" or "Devices" section displays a list of all connected devices. The interface is more user-friendly: devices often have clear names and icons. You can block access for any selected device with one click. Blocking occurs instantly, and the user immediately loses their internet connection.
However, the mobile app has its limitations. It doesn't always display detailed technical information, such as the exact connection time or the amount of data consumed by a specific device. Furthermore, the app requires a stable internet connection and authorization using the account number or phone number linked to the contract.
⚠️ Note: App functionality depends on the router model. On older models (for example, some versions of the Sagemcom F@st 2804), functionality may be limited to viewing the router's status, without the ability to block it through the app.
Network protection and blocking of intruders
Detecting an intruder is only half the battle. The main goal is to prevent re-intrusion. The most effective method is to change your Wi-Fi password. Go to your wireless network settings (Wireless or WLAN) and find the field WPA Pre-Shared Key or "Password." Create a complex combination of letters and numbers. After saving the settings, all devices will be disconnected, and you'll need to reconnect your devices with a new password.
An additional security measure is MAC address filtering. You can enable "White List" mode in your router settings. In this mode, only devices whose MAC addresses you manually add to the list will be able to access the network. All others, even with the password, will be blocked. This is the most reliable, but also the most labor-intensive method, especially if you frequently have guests.
It is also recommended to disable the function WPS (Wi-Fi Protected Setup). This technology allows you to connect to a network by simply pressing a button or entering a PIN, but it has vulnerabilities that are often exploited by attackers to brute-force the password. In the router interface, find the WPS section and set the switch to "Disabled."
Frequently Asked Questions (FAQ)
Can my neighbor find out my Wi-Fi password?
Theoretically, yes, if you use a weak password or the outdated WEP encryption protocol. Modern WPA2/WPA3 protocols are extremely difficult to crack using brute-force attacks, but it is possible through WPS vulnerabilities or if a virus steals the password from one of your devices.
Why does the device list show "Unknown device"?
This happens when a device doesn't broadcast its hostname when connecting. This is often the case with budget smart home gadgets, older phones, or Linux/Android devices with network visibility disabled. Check the MAC address to identify the owner.
Will changing the password reset the router settings?
No, changing the Wi-Fi password does not affect other settings (PPPoE, IPTV). However, if you perform a full reset using the reset button on the router, the router will return to factory settings, and the internet will stop working until you reset your ISP.
How often should I change my Wi-Fi password?
For security purposes, we recommend changing your password every 3-6 months, especially if you've noticed suspicious activity or shared the password with a large number of guests. You should also change your password whenever you purchase a new router.
Is browsing history visible through a router?
Rostelecom's standard routers typically disable logging of visited websites by default due to memory constraints. While the provider technically has access to traffic data, it does not disclose it to users without a request from law enforcement.
