When internet speed suddenly drops and browser pages load with a noticeable delay, subscribers often panic. Many immediately suspect their provider of dishonest service, although the cause could be as simple as neighbors stealing their data. In densely populated urban areas, wireless signals easily penetrate walls, becoming accessible to strangers unless you set a secure password.
For the company's subscribers Rostelecom There are several effective ways to audit connected clients. You can use both the router's built-in capabilities and specialized mobile apps that automatically scan the network. It's important to understand that promptly detecting uninvited guests will not only help restore your previous speed but also protect your personal data from potential interception.
In this article, we'll take a detailed look at all available monitoring methods, from simple buttons on the device's body to in-depth log analysis via a web interface. You'll learn how to distinguish your devices from others, block intruders, and configure your network so that only trusted individuals have access in the future.
⚠️ Attention: Personal account interfaces and router settings may be updated. If you don't find the menu item described, check the latest instructions on the official website of your equipment manufacturer or in the "Help" section of your provider's website.
Using the official My RTK app
The easiest and fastest way for owners of modern routers is to use a proprietary application from the provider. My RTK (formerly known as "My Rostelecom") allows you to manage your home network directly from your smartphone, anywhere in the world. To use the system, you'll need to log in using your account number or the phone number linked to your contract.
After logging in, go to the hardware management section. This displays a list of all active devices currently consuming data. The app automatically detects the device type (smartphone, laptop, TV) and displays the data transfer speed for each. This allows you to instantly identify anomalies, such as an unknown "Smart TV" downloading 4K movies while you're trying to work.
The app's functionality isn't limited to just viewing. You can remotely reboot your router, change your Wi-Fi password, or completely block access for a specific device with a single click. This approach is ideal for users who don't want to deal with complex technical settings and prefer to handle issues through a clear graphical interface.
- 📱 Convenience: Access network management from any smartphone running Android or iOS without having to remember the router's IP address.
- 🔒 Safety: Instantly block suspicious devices and change the encryption key in a couple of clicks.
- 📊 Statistics: View connection history and traffic volume consumed by each device for a selected period.
Checking via the router's web interface
A more advanced method that gives you complete control over your equipment is accessing your router settings through a web browser. This method is universal and works for all models, whether Sagemcom, Eltex or ZTE, which are often provided by your ISP. First, you need to connect to your network (via Wi-Fi or cable) and enter the gateway IP address in the browser's address bar.
The standard address most often looks like this 192.168.0.1 or 192.168.1.1If these combinations don't work, turn the router over—the sticker on the bottom usually indicates the exact address, as well as the login and password. By default, Rostelecom devices often use the combination admin / admin or admin / unique password from the sticker.
After successful authorization, the control panel will open. You need to find the tab responsible for the wireless network. Depending on your router model, it may be called WLAN, Wireless, Wi-Fi or Wireless networkWithin this section, look for a subsection with the status or list of clients. It may be called Associated Stations, Client List, Client list or Statistics.
The list that opens will display all devices currently connected to your network. You'll see their MAC addresses, IP addresses, and connection times. To figure out who's who, you'll need to match the MAC addresses with your devices. On smartphones and laptops, you can usually find the address in the "About phone" or "Network properties" sections.
What should I do if my router password doesn't work?
If the default admin/admin password isn't working and you haven't changed yours, the setup wizard may have changed the password during installation. Try finding it on the sticker. If that doesn't help, you'll need to perform a factory reset, which will require you to set up your internet connection again.
Analyzing the list of connected devices
After receiving a list of MAC addresses, many users face a challenge: how do you figure out which one belongs to your TV and which to your neighbor's laptop? This is where the method of elimination and knowledge of MAC address markings come in handy. A MAC address consists of 12 characters (numbers and letters), separated by colons or hyphens, for example: 00:1A:2B:3C:4D:5E.
The first six characters (three bytes) are called the OUI (Organizationally Unique Identifier). They are unique to each hardware manufacturer. Knowing these characters makes it easy to identify the device's brand. There are special online services and tables where you can simply enter the first three pairs of characters to find the manufacturer.
Additionally, the web interface of many modern routers allows you to assign user-friendly names to devices. If you see a device with the name Ivan-iPhone, then there are no problems with identification. However, other people's devices often appear as Unknown Or simply a set of symbols. Carefully count your gadgets: household phones, smart plugs, speakers, and game consoles.
| Manufacturer | Example of the beginning of a MAC address | Typical device |
|---|---|---|
| Apple | 00:1C:B3, D8:9E:62 | iPhone, iPad, MacBook |
| Samsung | 00:1A:8A, 3C:25:1E | Smartphones, TVs, tablets |
| Xiaomi | 64:09:80, 28:6C:07 | Phones, routers, gadgets |
| Intel | 00:1E:33, 94:65:2D | Wi-Fi adapters for laptops |
| Huawei | 00:1E:10, 14:7D:DA | Routers, smartphones |
If, after recounting, you discover an extra device that you don't recognize and that doesn't belong to your guests, it means your Wi-Fi is being used by strangers. Don't ignore this, as it not only reduces speed but also poses risks to your digital security.
Using third-party programs for PCs and smartphones
If your router's built-in tools seem inconvenient or buried too deep in the menu, you can use specialized software. There are numerous network scanning tools available for Windows computers and mobile platforms. They often provide more detailed information and a user-friendly interface.
One of the most popular and reliable programs for PC is Wireless Network Watcher from NirSoft. It's a tiny utility that requires no installation. Once launched, it instantly scans the network and lists all active hosts. The program highlights new devices that appear on the network and allows you to export a report.
For owners of smartphones based on Android And iOS the app would be perfect FingThis is a powerful network scanner that not only displays a list of devices but also identifies their model, operating system, and even their approximate location. The app is free and available in official app stores.

How to block uninvited guests
Detecting an intruder is only half the solution. The main goal is to block their access to your network. The simplest, but not the most effective, method is to simply change your Wi-Fi password. After changing the key, all devices will be disconnected, and you'll have to reconnect them with the new password.
A more advanced approach is to use MAC address filtering. This feature allows you to create a "whitelist" of devices that are allowed to connect. All others, even with the password, will be blocked from access. Configuration is done in the section Wireless MAC Filtering or MAC address filtering in the router's web interface.
To activate protection, follow these steps: copy the MAC addresses of all your devices to the allowed list, enable "Allow" mode (Allow only listed), and save the settings. After this, your network will be completely closed to outsiders. However, keep in mind that if you buy a new phone, you'll need to manually add its address to your router settings.
☑️ Wi-Fi Security Checklist
⚠️ Attention: The WPS (Wireless Protected Setup) function is one of the most vulnerable points in router security. Hackers can crack the WPS PIN code in a matter of hours. It's recommended to disable WPS in your router settings unless you regularly use it for guest connections.
Preventing and enhancing network security
To avoid the question of "how to find out who's using Wi-Fi" from becoming a pressing issue, you need to follow basic digital hygiene rules. This primarily applies to passwords. Never leave the factory password printed on a sticker, especially if the router is located in an accessible location or the signal is well outside your home.
Use modern encryption standards. In the wireless network settings (Wireless Settings) select security mode WPA2-PSK or, if your hardware supports it, WPA3Old protocols WEP And WPA can be hacked in minutes using programs available on the Internet.
Also, don't forget to update your router's firmware. Manufacturers regularly release updates that patch security holes. You can check for a new version in the section System Tools -> Firmware Upgrade or via automatic update in the provider's application.
Regular monitoring and proper equipment configuration will allow you to enjoy high-speed internet without lag or queues. Remember, the security of your home network is primarily your responsibility, and simple steps can protect your personal data from being leaked.
Frequently Asked Questions (FAQ)
Can my neighbor hack my password if it is complex?
Theoretically, any password can be cracked using brute-force, but it would take years. However, if you have WPS enabled, an attacker can bypass your Wi-Fi password by guessing the WPS PIN. Therefore, be sure to disable WPS in your router settings.
Why do I see "Unknown Device" in the list of devices?
This means the router can't identify the device's manufacturer based on its MAC address. Smart gadgets (light bulbs, sockets), old phones, or devices with non-standard network cards often display this error. Try disconnecting your devices one by one to identify the "unknown" one.
Does the number of connected devices affect the speed?
Yes, directly. The Wi-Fi channel is shared among all active users. If one of your neighbors starts downloading torrents or watching 4K videos, your browsing and messaging speeds can drop to practically zero, as the airtime will be completely occupied.
What should I do if I changed my password but my speed hasn't increased?
The problem may not be Wi-Fi theft, but rather channel congestion from neighboring routers (especially in apartment buildings), malfunctioning ISP equipment, or viruses on your own devices. Try changing the Wi-Fi channel in your router settings to a less congested one (for example, to 1, 6, or 11 for the 2.4 GHz band).
