Slow internet speeds, sudden connection drops, and suspicious network activity are just the first warning signs that a third-party user has connected to your router. In dense urban areas and with shared communication channels, an unsecured access point becomes easy prey for neighbors or hackers using automated network scanners. Knowing how to check the list of connected devices is a basic digital hygienist skill that helps maintain the privacy of personal data and the stability of your connection.
Operator Rostelecom provides subscribers with a wide range of equipment, from classic models ZTE And Sagemcom to modern dual-band routers Sercomm And EltexThe control interfaces for these devices may differ significantly visually, but the menu logic and network protocol operating principles remain the same for all systems. In this article, we'll detail the algorithms for various interface types so you can quickly identify uninvited guests and block their access.
Before diving into technical details, it's important to understand the risks of open access. An intruder on your network can not only consume traffic, but also intercept unencrypted data, inject malware into local devices, or use your IP address for illegal online activity. Therefore, regularly monitoring your client list is not just a way to optimize speed, but a necessary measure. cybersecurity.
Visual diagnostics and software detection methods
The easiest way to perform a basic diagnosis is to monitor the indicators on the router. If you've disconnected all your devices and computers from the network, but the indicator WLAN or WiFi If the LED continues to flash rapidly, this is a sure sign that another device is actively transmitting data. However, this method doesn't provide precise information about the device connected, so a detailed check requires the use of software tools.
There are many specialized tools for scanning local networks that work on the principles of ARP table analysis. One of the most popular and reliable programs for PCs is Wireless Network Watcher or Advanced IP ScannerThese utilities scan the entire address range and list all active hosts, displaying their IP addresses, MAC addresses, and network card manufacturers. For mobile users, there are apps like Fing, which perform a similar function directly from your smartphone.
⚠️ Attention: Network scanners can be detected as a threat by antivirus software because they actively scan ports. Before running them, make sure you're on a trusted home network and not on public Wi-Fi.
Using third-party software is convenient for a quick check, but it doesn't provide access control. To actually block the intruder, you'll still have to access the router's settings. Furthermore, some advanced users can hide their devices from simple scanners by changing the MAC address, so the data obtained through the router's web interface is the most reliable and up-to-date.
Login to the web interface of Rostelecom routers
To obtain accurate information about connected clients, you need to log in to the router's administrative panel. This can be done through any browser by entering the gateway's IP address in the address bar. Rostelecom The default address most often used is 192.168.0.1 or 192.168.1.1If the default addresses are not suitable, you can find out your gateway through the Windows command line by entering the command ipconfig and finding the "Default Gateway" option.
When the authorization window appears, you will be asked to enter your login and password. In factory settings, this information is usually found on a sticker on the bottom of the device. A combination of admin / admin or admin / unique password from the sticker. If you've previously changed your login details and forgot them, you'll need to perform a factory reset using the button. Reset, which will require you to reconfigure your Internet connection.
☑️ Checking access to the router
It's important to understand that the interface may differ depending on the model. Older models D-Link or Upvel, which were previously issued en masse by the operator, have a gray or blue interface, while the new ones Sercomm And Eltex Use modern web interfaces with HTML5 support. Regardless of the firmware version, look for sections with the words "Status," "Client List," "DHCP," or "Status," "Clients," or "Local Network."
Analyzing the client list in the Sercomm and Eltex interface
Modern routers such as Sercomm FG1500 or Eltex NTU-2, have a fairly user-friendly interface. After logging in, pay attention to the main page or the "My Devices" section. A graphical network map is often displayed here, showing the number of connected devices. For a detailed view, go to the "My Devices" section. Local area network (Local Network) -> Client list (Client List) or DHCP -> Address rental (DHCP Lease).
In the table you will see a list of all active connections. The key parameters here are MAC address (unique identifier of the network card) and IP addressThe device name (Hostname) may not always be listed or may be unclear (e.g., android-xyz), so use the MAC address first. Compare the list with your existing devices. If you see an unknown device, write down its MAC address—you'll need it to block it.
