How to check Rostelecom Wi-Fi for unauthorized connections: 5 working methods

Have you noticed that the internet is Rostelecom started working slower, even though the tariff didn't change? Perhaps, to your Wi-Fi third-party devices connected—neighbors, random passersby, or even hackers exploiting router vulnerabilities. According to KasperskyOne in five home routers in Russia has weak security settings, making networks an easy target for unauthorized access.

In this article we will look at how check Wi-Fi for unauthorized connections specifically from the provider Rostelecom — taking into account the features of their equipment (routers Sagemcom, Sercomm, Huawei) and the proprietary "Home Internet" app. You'll learn how to identify "unnecessary" devices through the web interface, mobile app, and specialized programs, as well as how to block them and strengthen network security. All methods have been tested on the latest router firmware. Rostelecom (2023–2026).

1. Checking via the Rostelecom router web interface

The most reliable way is to go to the router control panel. Rostelecom The web interface address depends on the device model, but most often it is 192.168.1.1 or 192.168.0.1The default login and password are indicated on the sticker on the bottom panel of the router (usually admin/admin or user/user).

Instructions for popular models:

• 🔹 Sagemcom F@st 2804/5260: go to Advanced Settings → Local Network → DHCP → Client Table.
• 🔹 Sercomm RV6699: open Network → Local Network → List of Connected Devices.
• 🔹 Huawei HG8245H: go to Network → LAN → DHCP Client List.

In the table you will see all the devices connected to your network, indicating:

• 📱 IP addresses (For example, 192.168.1.102);
• 🖥️ MAC addresses (unique species identifier 00:1A:2B:3C:4D:5E);
• 🕒 Connection time;
• 🏷️ Device name (if it is transmitted, for example, iPhone-12-Pro).

Check the MAC address using a search engine (it may belong to your gadgets)

Disconnect the device from the network (the "Block" button)

Change your Wi-Fi password to a more complex one

Update your router firmware-->

How to distinguish your device from someone else's? Compare the MAC addresses in the table with those of your devices. Here's how to find the MAC address of your phone or laptop:

• 📱 Android: Settings → About phone → General information → Wi-Fi MAC address.
• 🍎 iPhone/iPad: Settings → Wi-Fi → ⓘ next to the network → MAC address.
• 💻 Windows: run the command ipconfig /all V Command line.

What should I do if the web interface doesn't open?

If the page 192.168.1.1 does not load, check:

1. Are you connected to the router via cable or Wi-Fi (not via mobile Internet).

2. Disable your VPN or proxy—they may be blocking access.

3. Try a different browser (for example, Firefox instead of Chrome).

4. Reset the router using the Reset button (hold for 10 seconds) if you have forgotten the password.

After reset, the login/password will become standard (see the sticker on the router).

2. Checking via the Rostelecom Home Internet app

If you have the official app installed Rostelecom ("Home Internet"), the check will take less than a minute. The application is available for Android And iOS, but the functionality may differ depending on the router model.

Step-by-step instructions:

1. Open the application and log in with your username. Rostelecom.
2. Go to the section My Network → Connected Devices.
3. Browse the list of gadgets. You can also block unknown devices (the "Deny access" button).

🔍 Advantage of the method: in the application, devices are displayed with icons (smartphone, laptop, TV), which makes identification easier. However, some models of routers (for example, old ones) D-Link) may not support this feature through the app - in this case, use the web interface.

3. Using third-party programs to scan the network

If standard methods haven't revealed any suspicious devices, but your internet connection is still slow, use specialized utilities. They scan the network and identify all connected devices, including those that may be hiding behind a VPN or proxy.

Top 3 programs for Windows, macOS And Android:

🛠️ How to use Wireless Network Watcher:

1. Download the program from official website (free, no installation required).
2. Run the file WNetWatcher.exe (does not require administrator rights).
3. Click Start Scanning — after 10–20 seconds, a list of all devices on the network will appear.
4. Pay attention to the column Device Information - there may be the name of the manufacturer (for example, Xiaomi, Samsung).

4. Traffic Analysis: How to Identify "Invisible" Internet Thieves

Some hackers connect to the network but do not show up in the standard device lists. They may use MAC address spoofing (ID substitution) or connect via guest networkIn such cases, traffic analysis can help.

📊 Methods of analysis:

• 🔍 Via a router: in the web interface, open Statistics → Traffic by Device (available on Sagemcom And Huawei). Compare the amount of downloaded data—if one device is consuming gigabytes in the background, this is a cause for concern.
• 🖥️ Through Wireshark: The program intercepts all packets on the network. Look for suspicious ones. DNS queries or connections to unfamiliar IPs (for example, in China or the USA, if you haven't used them).
• 📱 Through GlassWire (Android/Windows): Shows real-time traffic and identifies the apps consuming it.

⚠️ Warning: If you find a device with high traffic, but you are not sure that it is someone else's, temporarily turn off the Internet (pull the cable out of the router or press the button WPS (for 5 seconds). If the traffic continues to grow, there is definitely an "outsider" on the network.

5. How to block unauthorized connections

Found someone else's devices? Follow these steps:

1. Block the MAC address:
   • In the router's web interface, go to Wireless Network → MAC Filter.
   • Add suspicious MAC addresses to the blacklist (or allow only your addresses in the whitelist).
2. Change your Wi-Fi password:
   • Use WPA3-PSK (if supported) or WPA2-AES.
   • The password must be at least 12 characters long, with numbers, letters, and special characters (e.g. k7#pL9!mQ2$vR).
3. Disable WPS:
   • Function WPS vulnerable to brute-force attacks. Disable it in Wireless Network → WPS → Disable.

Update your router firmware:

• In the section System → Software Update Check if the version is up to date.

⚠️ Attention: If the device continues to appear on the network after blocking the MAC address, it may mean that the hacker is using spoofing (MAC spoofing). In this case:

• 🔄 Reset your router to factory settings (button Reset).
• 🔒 Turn on hiding SSID (in the Wi-Fi settings, check the box “Hide network”).
• 🛡️ Install VPN on a router (if supported).

6. Additional measures to protect the Rostelecom network

To minimize the risk of future hacking, follow these steps:

• 🔄 Change your Wi-Fi password regularly (once every 3-6 months).
• 📡 Disable remote control of your router (System → Remote Access → Disable).
• 🔍 Enable logging (connection logging) in the router settings.
• 🛡️ Use Parental control to restrict access at night.
• 📱 Install the application Rostelecom Security (available to subscribers) - it monitors the network for suspicious activity.

💡 Tip for advanced users: set up network segmentation (VLAN) via a router to separate traffic from smart devices (cameras, light bulbs) and essential gadgets. This will make it more difficult for hackers to access sensitive data.

7. What to do if nothing helps?

If, after all these steps, other people's devices continue to appear on the network, it's possible:

• 🕵️‍♂️ Your router hacked at the firmware level (software with a backdoor installed).
• 📡 Your network is connected via a neighbor's router with the same SSID (rarely, but it happens).
• 🔌 There is in the house hidden device (for example, a smart plug or camera) that you haven't taken into account.

🆘 Actions in a critical situation:

1. Call support Rostelecom by number 8 800 100 08 00 and report the problem. A specialist can remotely check your router settings.
2. If you suspect firmware hacking, buy a new router (we recommend models with support WPA3, For example, TP-Link Archer AX21 or Keenetic Extra).
3. File a police report if there is evidence of a targeted hacking attack (such as data or money theft).
