How do I find out who is connected to my Rostelecom WiFi router?

Slow internet speeds, sudden connection drops, or incorrect smart home functionality—these symptoms often indicate an uninvited guest has connected to your network. In dense urban areas and the widespread use of wireless technologies, Wi-Fi becomes a vulnerable point, especially if the password was chosen too simple or was passed on to friends without the possibility of changing it in the future.

Operator Rostelecom provides subscribers with modern equipment that allows them to effectively manage their authorized client list. However, default settings are often overlooked, opening the door to malicious traffic. In this article, we'll examine methods for detecting rogue devices through a web interface, mobile apps, and specialized software.

Timely detection of unauthorized access will not only restore comfortable operating speeds but also protect personal data from potential interception. We'll examine how the standard Sagemcom router administration tools Eltex And Sercomm, as well as third-party utilities for deep network analysis.

Indirect signs of unauthorized access

Before resorting to technical diagnostics, it's worth paying attention to indirect symptoms that are often ignored by users. If your data plan hasn't changed, but page loading speeds or video streaming have dropped significantly, this is the first sign of bandwidth congestion.

The second important indicator is the behavior of the indicators on the router body. The light WLAN or Wi-Fi, which flashes intensively even when all your devices are turned off or in sleep mode, indicates active data transfer in the background.

⚠️ Attention: Intensely blinking lights may also indicate a router software glitch or a background system update. Don't rush to change the password until you've thoroughly diagnosed your client list.

A third sign may be the inability to connect to the home network from a priority device when the router reports that the connection limit has been exceeded. Standard models often limit the number of simultaneous clients (usually to 16 or 32), and "excess" users crowd out legitimate ones.

To make an initial assessment of the situation, you can use the following checklist:

• 📉 Have you noticed a sharp drop in speed during rush hour?
• 💡 Does the wireless indicator blink when gadgets are sleeping?
• 📱 Do you receive notifications about new account logins?
• 🔌 Are your personal devices refusing to connect?

Checking via the router's web interface

The most reliable and accurate way to find out who is using your Wi-Fi is to log into your router's admin panel. The equipment provided Rostelecom, most often has standard login addresses such as 192.168.1.1 or 192.168.0.1To access, you must enter your login and password, which are usually located on a sticker on the bottom of the device.

After authorization, you'll need to find the section responsible for the wireless network status or client list. Depending on your model and firmware version, this section may be called WLAN, Wireless, Host Info or Client listThis is where a table of all devices currently online is displayed.

In the table, you'll see MAC addresses, IP addresses, and often device names. To figure out which is which, you need to check the MAC addresses against known devices. If you see a device with the name Unknown or manufacturer, this is a cause for concern.

Below is a table of typical paths to the required menu for popular Rostelecom router models:

Please note that some firmware versions may be updated remotely, and the menu structure may change slightly. If you can't find the section you need, use the settings search or refer to the manual for your specific model.

Using the Rostelecom WiFi mobile app

For users who find it difficult to work with browser settings, the operator has developed a user-friendly mobile application. Rostelecom WiFi (formerly known as Wifir). This is a modern tool that allows you to manage your network directly from your smartphone, anywhere in the world with internet access.

After installing the app and linking your device via your account number or serial number, you gain access to the dashboard. Here, a list of connected devices is displayed in real time. The app automatically detects the device type (iPhone, Android, Windows) and its name, significantly simplifying identification.

The app's main advantage is its instant blocking feature. If you detect an unknown device, simply tap it and select "Block" or "Restrict Access." This action will immediately terminate the connection for the selected client.

What should I do if the app doesn't see the router?

Make sure your smartphone is connected to the same Wi-Fi network you're testing. Remote management requires the router to be linked to the operator's cloud service and have an active internet connection. Also, check that the router isn't in "Bridge" mode, which disables router functions.

The app also features a guest mode feature. You can create a temporary network with a limited time or data limit for guests, protecting your main network from outsiders.

Network analysis using third-party programs

If standard methods don't seem informative enough, specialized network scanning utilities can come to the rescue. Programs like Fing, WireShark or Advanced IP Scanner are able to show much more detail about each connected node.

These programs scan the entire range of IP addresses in your subnet and generate a detailed report. You'll be able to see not only the MAC address, but also the network card manufacturer, open ports, and even the device's operating system. This is especially useful for detecting hidden miners or surveillance cameras.

However, it's important to remember the safety of using third-party software. Download programs only from the developers' official websites to avoid infecting your computer with a virus disguised as a "network analyzer."

• 🛡️ Fing — the best mobile app for quick scanning.
• 💻 Advanced IP Scanner — a lightweight and fast scanner for Windows.
• 🔍 WireShark — a professional tool for deep traffic analysis.

Using such tools requires a basic understanding of network protocols, but provides the most complete picture of what is happening on the air.

How to block intruders and protect your network

If you detect a foreign device, you need to act quickly. The easiest way is to change your wireless network password. After changing the security key, all connected devices will be disconnected and will need to enter the new password to reconnect.

A more sophisticated method is filtering by MAC addresses. In the router settings (section Wireless MAC Filter) You can enable the "White List" mode. In this case, only devices whose MAC addresses are manually added to the list will be able to access the network. All others, even with the password, will not be able to connect.

⚠️ Attention: Be careful with MAC filtering. If you buy a new phone or have guests over, you'll have to manually enter their addresses into your router settings each time, otherwise they won't have internet access.

It is also highly recommended to disable the feature WPS in the router settings. This technology is designed to simplify connections, but has known vulnerabilities that allow attackers to brute-force the network password in a matter of hours using special scripts.

For maximum security, use an encryption protocol. WPA2-PSK or WPA3, if your equipment supports it. WEP and WPA protocols are outdated and easily cracked.

Frequently asked questions and problems during verification

During diagnostics, users often encounter ambiguous situations. For example, a device named "Linux" or "Android" may appear in the list, even though you don't remember having such devices. These are often smart TVs, IPTV set-top boxes, or even routers themselves operating in repeater mode.

Another common problem is "dead souls." Devices that were connected a long time ago but are currently inactive may remain on the DHCP lease list for some time (until their IP address lease expires). This doesn't mean someone is using your internet right now.

If you've changed your password but your speed hasn't improved, the problem may not be your neighbors, but rather interference from neighboring routers on the same frequency or a malfunctioning ISP. In this case, analyzing channel load and manually changing them in your router settings will help.

What should I do if I can't access my router settings?

Make sure you're connected to this router's network via cable or Wi-Fi. Check the gateway address in your network adapter settings. If the default admin/admin password doesn't work, the password may have been changed previously. You'll need to reset the router by pressing the Reset button for 10-15 seconds.

Can my neighbor see my files via Wi-Fi?

If you don't have a guest network configured and files are shared in a shared folder without a password, this is theoretically possible. However, modern operating systems automatically detect a new network as "Public" when connecting and block access to shared resources.

Does the number of connected devices affect the speed?

Yes, the bandwidth is shared among all active users. If one of your connected users (yours or someone else's) is downloading torrents or watching 4K video, the others will only get a small portion of the bandwidth.
