Many users are familiar with the unexpected drop in internet speed and dropped video calls. Often, the cause isn't overloaded network traffic, but rather uninvited guests connecting to your wireless access point. If you're wondering who's connected to Rostelecom Wi-Fi right now, it's time to audit your home network. Modern routers and proprietary apps offer powerful monitoring tools, but you need to know how to use them.
In this article, we'll take a detailed look at all the available methods for monitoring connected devices. You'll learn how to identify yours. smartphone from someone else's tablet, which security settings are critical for protecting against hacking, and what to do if you detect suspicious activity. We'll cover both the router's web interface and the popular "My Rostelecom" app, which allows you to manage your network from your phone anywhere in the world.
⚠️ Please note: The personal account interface and router functionality may vary depending on the device model (Sagemcom, Eltex, Sercomm) and service region. Some menu items may have different names or be moved to other sections after an automatic firmware update.
Signs of unauthorized network access
The first sign that someone else is using your Wi-Fi is a sharp drop in connection speed. If your data plan allows for downloads of 100 Mbps, but the actual speed is only 10-15 Mbps with no active downloads, you should be wary. This is especially noticeable in the evening, when network load is already high, but the drop should be noticeable. Unstable ping In online games, it can also indicate that the channel is clogged with other people's traffic.
Another warning sign is strange behavior of the router's indicator lights. The WLAN or Wi-Fi light, which should flash in sync with data transfer, may be constantly on or flash erratically, even when all your devices are turned off or in sleep mode. This means there's an active exchange of data packets between the router and an unknown client. In some cases, users notice that WPS indicator lights up without their knowledge, which may indicate an attempt to automatically guess the password.
Modern Rostelecom routers often come equipped with a notification feature for new connections. If you've set up notifications in the app but haven't connected anything new, and a notification arrives, it's a clear call to action. It's also worth checking your devices' browser history: the appearance of unknown tabs or search queries may indicate that someone has accessed not only your network but also local resources.
Checking connected devices through the My Rostelecom app
The easiest and most accessible way to check who's using your Wi-Fi is to use the operator's official mobile app. It's available for iOS and Android platforms and allows you to manage services without having to remember complex IP addresses or log into a web interface. To get started, log in using your account number or the phone number associated with your contract. After logging in, select your plan or device. ONT terminal, if you have fiber optic internet.
In the app's main menu, find a section called "My Network," "Wi-Fi Management," or "Home Internet." A list of all active clients will be displayed there. The app typically displays the device name (e.g., iPhone 13, Samsung TV, Laptop), its IP address, and connection type (2.4 GHz or 5 GHz). If you see a device labeled "Unknown" or a name you don't recognize, this is cause for concern. The app's functionality often allows you not only to see the list but also to instantly block the offender with the click of a button.
The advantage of using the app is its remote control. Whether at work or on vacation, you can check the status of your home network at any time. If the app shows five devices connected to the Wi-Fi network, but you're home alone and have fewer devices, the password has been compromised. In such cases, the "My Rostelecom" feature allows you not only to disconnect the device but also to force a Wi-Fi password change, which will disconnect all clients and require re-authorization with a new key.
Analyzing the client list via the router's web interface
For users who prefer detailed control, the router's web interface provides much more technical information. To access it, you need to connect to a Wi-Fi or cable network and enter the gateway's IP address in the browser's address bar. For Rostelecom equipment, this is most often 192.168.1.1 or 192.168.0.1The login information (username and password) is usually located on a sticker on the bottom of the device, unless you've changed it before. The default login information often looks like this: admin / admin or admin / unique password from the sticker.
After successfully logging into the control panel (which may be called Fastweb, Sagemcom or have a logo RT) You need to find the section responsible for the network status. It may be called "Local Network," "LAN," "Status," "Monitoring," or "Client List." This section contains a table containing the MAC addresses, IP addresses, and hostnames of all connected devices. The MAC address is a unique identifier for a network interface, which is more difficult to forge than a device name, so it's the first thing you should look at.
☑️ Checking the router's web interface
The interfaces of different router models vary, but the logic remains the same. On Sagemcom routers, the path often looks like this: Advanced Setup -> LAN -> DHCP Server (or Client List). On older Eltex or D-Link models, look for the "Status" -> "Clients" tab. If you see a device that isn't on your list, write down its MAC address. You'll need this to set up filtering. It's important to understand that some "smart" devices, such as lamps, sockets, or vacuum cleaners, may have vague names like "Espressif" or "Tuya," so don't rush to block them until you're sure they belong to you.
| Device type | Example name (Hostname) | Manufacturer (by MAC) | Status |
|---|---|---|---|
| Android smartphone | Android-1234abcd | Samsung / Xiaomi | Actively |
| Windows laptop | DESKTOP-USER | Intel / Realtek | Actively |
| Smart TV | [TV] Samsung 6 Series | Samsung Electronics | Expectation |
| Unknown | Unknown | Unknown | Suspicious |
Methods for blocking unwanted users
If you've identified an intruder, the most effective method is MAC address filtering. This method allows you to create a "blacklist" of devices that will be denied network access at the router hardware level. In the web interface, find the "Security" section, then "MAC Filter" or "Access Control." Select "Deny/Blacklist" and add the intruder's MAC address to the list. After applying the settings, the device will lose connection and will be unable to reconnect, even with the correct password.
A more radical, but often necessary, step is to completely change your Wi-Fi password. Changing the security key will disable all connected devices. You'll have to re-enter the password on each device, but this ensures that only those you personally share it with will have access. It's recommended to use a complex password consisting of mixed-case letters, numbers, and special characters, at least 12 characters long. Avoid using simple sequences or birthdays.
What to do if an intruder changes the MAC address?
Some advanced users can clone the MAC address of an authorized device. In this case, the only solution is to enable stealth SSID mode (so the network doesn't appear in the list of available networks) and use access time filtering, if the router supports such features.
It's also worth paying attention to the WPS function. This protocol is designed to simplify connections, but it often contains vulnerabilities that allow someone to brute-force the PIN code and gain access to the network. If you don't use WPS, it's highly recommended. disable this feature in your router settings. This will close one of the most common loopholes for hacking Wi-Fi networks by neighbors or random passersby with laptops.
Setting up wireless network security
Your network security starts with choosing the right encryption protocol. In Wireless Settings, make sure the security type is selected. WPA2-PSK or, if the equipment supports it, WPA3Outdated WEP or WPA (TKIP) protocols are easily cracked by automated programs in minutes. Rostelecom routers are typically configured for WPA2 by default, but these settings can change after a reset or due to interference from "knowledgeable" neighbors.
Another important step is changing the password for your router's admin panel. The factory passwords (admin/admin) are known to all hackers and scripts. Go to the "System Tools" or "Administration" section and set a unique password. This will prevent an attacker from gaining access to your network and reconfiguring your router, rerouting traffic, or blocking your access to managing your own equipment.
Don't forget to regularly update your router's firmware. Manufacturers constantly release patches to close security holes. In the router interface, find the "Firmware Update" section and check for new versions. Some Rostelecom models can update automatically, but it's best to check manually periodically, especially if you notice unusual network behavior.
Frequently asked questions and problems during verification
Users often encounter a situation where the list of connected devices shows gadgets they don't recognize. In 90% of cases, these are forgotten connected devices: e-readers, old phones, smartwatches, set-top boxes, or even a neighbor's TV if the password was entered incorrectly. Before panicking, conduct a complete inventory of all the equipment in the house, including guest devices.
Sometimes a router may show an incorrect number of connections due to software errors or a DHCP table freeze. In this case, a simple reboot of the router via the web interface or the power button can help. If, after a reboot, the "extra" device reappears and actively consumes traffic, then it's time to sound the alarm. It's also worth considering that dual-band routers may display a single physical device as two different devices (separately for 2.4 GHz and 5 GHz) if it's connected to both networks.
⚠️ Note: Blocking a device by MAC address is only effective until the intruder changes it. However, for typical home use, this level of protection is sufficient, as mass-market scanners rarely have the ability to automatically bypass such filters.
In conclusion, regularly monitoring connected clients is a good habit for any home internet owner. It not only saves traffic and maintains speed, but also protects your personal data from potential interception. Use a combination of mobile apps for quick monitoring and a web interface for advanced security settings to feel confident in the digital world.
How do I find out my phone's MAC address for comparison?
On Android, go to Settings -> About Phone -> Status (or tap your network name in the Wi-Fi section). On iPhone: Settings -> General -> About -> Wi-Fi Address. Compare this information with the one on your router.
Can a neighbor steal my internet if I change my password?
If you've changed your password to a complex one and use WPA2/WPA3 encryption, then it's virtually impossible to steal your internet connection. You won't reveal your password yourself, and it won't be intercepted by special programs when exploiting the WPS vulnerability.
Why is the name "Unknown" in the device list?
An "Unknown" name means the device isn't broadcasting its network hostname or the router can't read it correctly. This is normal for some IoT devices (light bulbs, sensors), but it can also mask the identity of someone else's device. Use the manufacturer's MAC address as a guide.
Will changing the password reset the router settings?
No, changing the Wi-Fi password does not reset other router settings (connection type, telephony, IPTV). However, all devices will be disconnected from the wireless network and will require a new password to reconnect.
