In the age of ubiquitous smart gadgets, home networks are becoming increasingly connected, and users often can't accurately determine how much bandwidth their devices are consuming. If your internet has slowed down or you've noticed unusual indicator activity, the first step is to check whether your neighbors are hogging your access point. Rostelecom provides several ways to control this process, from the classic login to the router settings to mobile applications.
Understanding how to manage connections is critical to the security of your personal data and connection stability. An unknown device on your client list can not only steal traffic but also access local resources, such as network printers or shared folders on your computer. In this article, we'll cover in detail how to conduct a network audit using standard ISP tools and third-party diagnostic methods.
There are several levels of verification: from a quick assessment via a smartphone to a deep analysis of logs in the router's admin panel. Connection control It not only identifies uninvited guests but also prioritizes traffic for important tasks, such as video conferencing or online gaming. Below, we'll provide specific instructions for various hardware models.
Using the Sagemcom router web interface
The most common equipment among the provider's subscribers are routers of the brand Sagemcom, often found in the line Fast 2804 or more modern models of the series RTTo obtain accurate information about connected clients, you need to log in to the device's web interface. Open any browser and enter the local IP address in the address bar, usually 192.168.1.1 or 192.168.0.1.
After entering your login and password (by default they are often indicated on the sticker on the bottom of the case, if you have not changed them), go to the section Advanced Setup or Additional settingsWe are interested in the tab LAN, and inside it a subsection DHCP Server or DHCP Client ListThis is where the table of active IP address tenants is displayed, that is, all devices that have access to the network at the current moment.
In the list provided, you will see MAC addresses, IP addresses, and sometimes hostnames of connected gadgets. MAC address — This is a unique identifier for a network interface, which is harder to spoof than a device name. If you see a device with an unfamiliar MAC address that doesn't belong to your smart lights, TV, or family members' phones, it's cause for concern.
⚠️ Note: Firmware interfaces may vary depending on the router's year of manufacture and software version. If you can't find the exact menu name, look for sections labeled "Status," "Client," or "Wireless."
For easier data analysis, it's recommended to compare the number of devices with the actual number of gadgets in the home. Below is a table that helps decipher the key parameters displayed in the client list:
| Parameter | Description | Value to check |
|---|---|---|
| Host Name | Device name on the network | For example, iPhone-Ivan, Samsung-TV |
| IP Address | Internal address | Format 192.168.xx |
| MAC Address | Physical address | Format AA:BB:CC:DD:EE:FF |
| Lease Time | IP lease time | Shows how long the connection lasts. |
What should I do if my device name is not displayed?
Some gadgets, especially IoT devices (smart plugs, sensors), may not transmit their hostname and appear as Unknown or simply a string of characters. In this case, rely solely on the MAC address, the first three pairs of characters of which (OUI) indicate the manufacturer.
Testing with Eltex and Huawei routers
Devices from other manufacturers often serve as an alternative to Sagemcom. Eltex And Huawei, which are also actively used by the infrastructure RostelecomThe logic for searching for customer information is similar here, but menu navigation has its own peculiarities. In devices Eltex (for example, models NTU-RG-1402G-W) after logging in (address 192.168.0.1) you need to go to the tab LAN and select the item DHCP Leases.
A list of all issued addresses is displayed here. A feature of the interfaces Eltex is the ability to see not only current connections, but also history, if this function is activated in the logs. For Huawei (series EchoLife) the path often lies through the tab Home Network or WLAN, where there is an item in the side menu WLAN User Access Control or just a list of users.
It is important to note that in some firmware versions Huawei the list can be divided into wired (LAN) and wireless (WLAN) connections. Wireless clients Wi-Fi is the most important network security feature, as it's the easiest way for unauthorized access to be gained. Make sure you're checking the wireless portion of your network.
☑️ Router security check
Rostelecom and Dom s Cloud mobile applications
The most modern and convenient monitoring method for most users is the operator's official mobile app. It allows you to manage services and equipment remotely, without having to remember IP addresses and router passwords. Download the Rostelecom or Home with Cloud app (depending on your tariff plan and equipment type) from App Store or Google Play.
After logging in using your contract number or phone number, find the section related to your Wi-Fi or router. The app interface often features a "My Devices" or "Clients" button, which displays all connected devices graphically. The app automatically assigns names and icons to device types (laptop, phone, TV), making identification much easier.
A huge advantage of the mobile method is the ability to instantly block. If you see a stranger, you can tap on them and select "Block" or "Restrict access." The system will apply a filtering rule based on MAC address at the level of the provider’s equipment or the router itself, if it supports remote management (TR-069).
Analyzing the connection list and identifying strangers
Once the device list is complete, the user is faced with the task of identifying them. Don't panic if you see more devices than you expected: modern homes are filled with technology we often forget about. Smart TVs, game consoles, smart speakers, robot vacuum cleaners, and even some refrigerators require a constant internet connection to update and function.
To determine this accurately, conduct an audit: turn off Wi-Fi on all your devices one by one and observe which one disappears from the list or changes status in the app. Continuous monitoring within 24 hours, it will help identify devices that connect periodically, for example, when you come home from work.
- 📱 Smartphones and tablets: usually have the model in the name (iPhone, Galaxy, Redmi).
- 🖥️ Computers: are often referred to by the username or have the prefix PC, Desktop, Notebook.
- 📺 Media devices: Android TV, Apple TV, Chromecast, Wink set-top boxes.
- 🏠 IoT gadgets: may have strange names (Tuya, Yeelight, Xiaomi) or have MAC addresses of unknown manufacturers.
⚠️ Note: Some devices may use the "Randomized MAC Address" feature to protect privacy. This means the same phone may appear as a new device in the router's list each time it reconnects.
If, after a thorough check, you're certain there's an extra device on the network, don't rush to change the Wi-Fi password if you suspect a guest may have previously gained access. First, try using the "Guest Network" feature, if available, to isolate the suspicious traffic.
Methods of protecting and blocking unwanted devices
The most effective way to get rid of unwanted guests is to change your Wi-Fi network password. Changing the password will disconnect all your devices, and you'll have to re-enter the new passkey on all your devices. This is guaranteed to disconnect anyone who knew the old password. Go to your wireless network settings (Wireless -> Security) and change the field Pre-Shared Key.
A more subtle instrument is MAC filteringThis feature allows you to create a "whitelist" of devices allowed to connect, or a "blacklist" to block specific addresses. In routers Sagemcom And Eltex this is done in the section Security or Access ControlYou copy the MAC address of the intruder and add it to the blocked list.
It is also recommended to disable the technology WPSThis feature is designed for quick connection without entering a password, but it has vulnerabilities that allow attackers to brute-force the PIN code and access the network even without knowing the main Wi-Fi password. You can find this option in the section Wireless -> WPSwhere to set the status Disable.
Frequently asked questions and additional settings
Users often have issues not only with blocking but also with network performance when there are a large number of connections. If you have more than 10-15 devices connected, a budget router may not be able to handle the load, even if they are all yours. In this case, rebooting the device or updating the firmware to the latest version can help.
Some router models allow you to limit the speed for individual clients. This is useful if one family member is actively downloading torrents, preventing others from watching 4K videos. This feature is called Bandwidth Control or "Speed Limit", and it is located in the advanced wireless network settings.
Regularly checking your client list is a good habit for any digital user. It not only helps protect your connection but also helps you understand your home's data usage patterns. If you notice that your old set-top box is constantly updating and consuming all your bandwidth, you can schedule updates for the night.
Can my neighbor see my files if he is connected to Wi-Fi?
By default, modern routers use client isolation or have firewall settings that prevent devices on the same network from seeing each other. However, if you have configured shared folders with easy access or the older SMBv1 protocol, theoretically access is possible. It's better to be on the safe side and change the password.
Why does the device list show "Unknown"?
This means the device isn't broadcasting its network name (hostname) or the router can't recognize it. This often happens with CCTV cameras, smart light bulbs, or Linux/Android devices with disabled authentication. Use the MAC address as a guide.
Will changing the password reset the router settings?
No, changing the Wi-Fi password does not reset other settings (PPPoE connection type, VLAN, etc.). However, all connected devices will lose connection and will require a new password to reconnect.
How often should connected devices be checked?
It's enough to check once a month or whenever you notice a significant drop in internet speed. For most users, setting up initial security and changing the password if you suspect something is wrong is sufficient.
