When internet speeds suddenly drop and pages load slowly, home Wi-Fi owners often become perplexed. Many immediately blame their ISP or line issues, but the real cause could be simple traffic theft by neighbors. In an age where passwords are often set weak or shared with guests, your connection becomes accessible to unauthorized users, which not only reduces speed but also compromises the security of your personal data.
You can detect "freeloaders" on your network without using a computer or installing cables. Modern technologies allow you to conduct a complete connection diagnostic directly from your smartphone, which is always at hand. For owners of equipment from Rostelecom are more fortunate than users of many other providers, as the operator provides convenient tools for network management via mobile apps and a web interface.
In this article, we'll take a detailed look at all the available methods for monitoring activity on your local network. You'll learn how to distinguish your devices from others, which security settings should be changed first, and how to block an uninvited guest with one click. Monitoring your home internet connection isn't just a technical whim, but a necessary element of digital hygiene that every user should understand.
Using the official My Home app
The simplest and most modern way to control access is to use a proprietary application. My Home (formerly known as "My Rostelecom"). This tool is designed specifically for remote management of services and equipment, providing the user with an intuitive interface. You don't need to be an IT specialist to understand its functionality, as all the necessary data is displayed on the main screen in the form of clear widgets and graphs.
To get started, you need to download the application from the official store. Google Play or App Store and log in using your account number or the phone number linked to your contract. After logging in, select your plan or device from the list of available ones. If you have equipment that supports the technology TR-069, which is managed remotely by the provider, you will see the “My Wi-Fi” or “Router Management” tab.
The wireless network management section displays a list of all active clients. The application not only shows MAC addresses Devices are often identified by their names (for example, "iPhone-Ivan" or "Samsung-TV"), making identification much easier. You can see in real time how much data your devices are currently consuming and, if necessary, disable suspicious connections directly from your smartphone's screen.
⚠️ Attention: The detailed view of connected devices is only available for routers managed by your provider. If you're using a store-bought device, the app can only display the network connection status, not the client list.
One of the app's key features is the ability to instantly change your password. If you discover an unknown device, there's no need to fiddle with complex browser settings. Simply click the "Change Password" button in the app, enter a new, complex code, and all connected devices will be disconnected. This is the fastest way to "kick" everyone out and start a new network, reconnecting only your devices with a new security key.
Checking via the router's web interface
If using the mobile app is impossible or inconvenient, an alternative method is to access the router settings through your smartphone's browser. This method is universal and works with virtually any hardware model, whether branded or not. Sagemcom, Sercomm or any other router operating under the provider's brand. You'll only need a browser (Chrome, Safari, Yandex) and access to a Wi-Fi network.
To access the control panel, open your browser's address bar and enter the gateway's IP address. The default address for most Rostelecom devices is 192.168.1.1 or 192.168.0.1The exact address is often indicated on a sticker on the bottom of the router case, where the login and password for entering the system are also located (usually this is admin/admin or a unique code from a sticker).
After successful authorization, you'll be taken to the settings interface. The interface may vary depending on the model, but the search logic remains the same. You'll need to find a section called "Status," "LAN," "Wireless," or "Client List." This is where you'll find complete information about who's currently using your access point.
☑️ Checking the web interface
In the active clients table, you'll see columns with IP addresses, MAC addresses, and connection status. Pay attention to the "Up Time" field—it shows how long the device has been online. If you see a device that's been online for several days, even though you were sleeping or at work at the time, this is a sure sign of unauthorized access.
⚠️ Attention: Firmware interfaces may change after automatic updates. If you can't find the section you need, look for subsections labeled "Statistics," "Association," or "DHCP Lease."
What to do if the admin password doesn't work?
If the default passwords don't work, they may have been changed by you or the technician during setup. In this case, the only solution is to reset the router to factory settings, after which the device will need to be configured again.
Analyzing the list of connected devices
Upon accessing the client list, the user is confronted with a series of numbers and letters that may seem meaningless without prior preparation. The key identifier here is MAC address — a unique code assigned to the network interface of each gadget during production. This code allows you to identify the device's manufacturer and match it with your own gadgets.
The first six characters of the MAC address (e.g. A4:C3:F0) indicate the hardware vendor. There are online databases that allow you to determine the brand of a device using these symbols: Apple, Samsung, Xiaomi, or, for example, Sony. By comparing the manufacturer and the number of your devices, you can easily identify the "outsider." For example, if you don't have Apple equipment, but the list shows a device with a MAC address starting with B8:17:52 (Apple), this is cause for concern.
It's also worth paying attention to the dynamic IP addresses that the router assigns automatically. They typically appear in the following order: 192.168.1.2, 192.168.1.3 and so on. If you see that 5 of your devices are online, and the sixth device has a newly assigned IP address, this may indicate that someone has just connected.
For ease of analysis, you can use the following table of MAC address prefixes corresponding to popular brands:
| MAC prefix (example) | Manufacturer | Typical devices | Probability of unauthorized access |
|---|---|---|---|
00:1A:2B |
Apple | iPhone, iPad, MacBook | High (if you don't have Apple technology) |
B8:27:EB |
Raspberry Pi | Microcomputers, smart home | Average (rare guest) |
D8:9E:F3 |
Ubiquiti | Professional network equipment | Low (rarely seen by ordinary users) |
AC:DE:48 |
TP-Link | Routers, adapters, cameras | Average (need to check your gadgets) |
Keep in mind that modern smartphones (iOS 14+ and Android 10+) can use a feature called "Private Wi-Fi Address" or "MAC Randomization." This means the device can mask its real address by generating a random one each time it connects. This can confuse analysis, creating the illusion of a new device, even though it's actually your own phone.
Blocking unwanted users
Detecting a rogue device is only half the battle. The main goal is to block its access to your network. Rostelecom routers have several security mechanisms, the effectiveness of which depends on the hardware model and firmware type. The most radical and effective method is a complete change of the WPA2/WPA3 security key.
Changing your password will disable all your devices. You'll have to re-enter the new password on each device. This is inconvenient if you have many devices, but it guarantees that all unauthorized users will be blocked, as the old password will no longer work for them. It's recommended to set complex passwords consisting of mixed-case letters, numbers, and special characters, at least 12 characters long.
A more flexible tool is MAC filteringThis feature allows you to create a "whitelist" (Allow List) containing only trusted MAC addresses. In this mode, the router will ignore any connection requests from devices whose addresses are not in the allowed list. Even if an attacker knows your password, they won't be able to access the network.
⚠️ Attention: Be extremely careful when setting up MAC filtering. If you accidentally fail to whitelist your current device's address, you will lose access to your router settings and internet connection, and you will have to press the Reset button.
Some advanced router models provided by your provider offer a "Guest Network" feature. This is ideal for temporary access. You create a separate access point with its own password, isolated from your main network. You provide your guests with the password for the guest network, while keeping your main devices within the secure perimeter.
Setting up Wi-Fi network security
Preventing repeat intrusions requires a comprehensive approach to security settings. It's not enough to simply remove a neighbor today; you need to ensure they can't connect tomorrow. The first step is to disable outdated encryption protocols. Make sure your wireless network settings are set to [unclear] WPA2-PSK or, if the equipment supports it, WPA3Protocols WEP And WPA (without a two) are considered hacked and do not provide adequate protection.
The second important aspect is disabling the function WPS (Wi-Fi Protected Setup). This technology is designed to simplify connecting devices with the push of a button, but it contains critical vulnerabilities that allow attackers to brute-force the network password in a matter of hours or even minutes. In the router interface, find the Wireless section and set the WPS setting to Disable or Off.
It's also worth paying attention to signal strength. If you live in an apartment building, there's no point in broadcasting your signal to the entire neighborhood. Reducing your transmitter power to a level sufficient to cover your apartment will reduce the likelihood that your signal will be picked up on the street or by distant neighbors.
Frequently asked questions and problems during verification
When monitoring a network, users often encounter ambiguous situations that require clarification. For example, a device with the name "Unknown" or a strange set of characters may appear in the list. These are often smart devices (light bulbs, sockets, vacuum cleaners) that don't correctly transmit their names to the network, or computers with a non-standard hostname.
Another common problem is "dead souls." The DHCP client list may display devices that were connected weeks ago but are no longer active. The router stores a record of leased IP addresses until the lease time expires. To clear the list, you can reboot the router or force a refresh of the DHCP lease list in the settings.
Some users ask if it's possible to track the location of someone connected. The answer is no, it's not possible through the standard router interface. You only see the connection and the MAC address. The exact physical location (address or apartment) cannot be determined technically; you can only roughly determine that the signal is coming from nearby apartments.
Why doesn't my router allow me to save my settings?
This often happens because the settings are saved to RAM and require a restart to apply, or because the browser is blocking the confirmation pop-up. Try using Incognito mode or a different browser.
Can my neighbor hack my Wi-Fi if I changed the password?
If the password is complex (more than 10 characters, multiple characters, and numbers) and WPA2/WPA3 encryption is used, brute-force cracking will take years. However, if a neighbor has handshake interception software installed and is a skilled hacker, it's theoretically possible, but in a residential setting, the risk is minimal. The main danger is password leakage through connected devices or WPS.
Does the number of connected devices affect internet speed?
Yes, it does have a direct impact. The Wi-Fi channel is shared among all active users. If your neighbor is downloading torrents or watching 4K video, your channel may be completely overloaded, even if you're just trying to open a webpage. Furthermore, a large number of devices puts a strain on the router's processor, which can cause lag.
What should I do if I see my router or extender in the list of devices?
If you have a complex network with repeaters (signal boosters) or a mesh system, they will also appear as clients of the main router. They usually have the model number or the word "Repeater" in their name. Don't block them, otherwise you'll lose connection to the network extenders. It's best to rename them to something more descriptive in the settings.
