A sharp drop in internet speed or persistent lag when watching videos are often the first signs that unauthorized individuals have accessed your home network. Beltelecom provides subscribers with modern equipment that allows them to easily manage the list of connected devices, but not all users know where to find this information. If you suspect something is wrong or simply want to conduct an audit of your digital security, you'll need to access your router's web interface.
There are several effective ways to identify uninvited guests, from accessing your router settings through a browser to using specialized mobile apps. The key point Understanding your device model is crucial, as providers often use equipment from different manufacturers, such as ZTE, Huawei, or Eltex. In this article, we'll detail the steps for the most popular terminal models so you can quickly regain control of your traffic.
Don't neglect periodic connection checks, especially if you live in a densely populated apartment building. Neighbors can accidentally or intentionally connect to open or poorly secured networks, which not only steals your traffic but also poses security risks to your personal data. Let's look at how to diagnose your connection and what steps you should take immediately.
Signs of unauthorized network access
The first and most obvious symptom of a "neighborly" connection is unstable internet service. If you notice that your page loading speed has dropped significantly, even though your data plan has remained the same, this is cause for concern. Technical specifications Most home routers are not designed to handle dozens of active devices simultaneously, and the addition of an extra subscriber can significantly reduce channel throughput.
Pay attention to the indicators on your device. If the WLAN (Wi-Fi) light is blinking rapidly, even when all your smartphones and laptops are turned off, it means there's active data transfer. Another warning sign is an inability to access the router settings or constant connection drops during online games or video calls.
⚠️ Note: Sometimes network slowness may be caused not by outside interference, but by technical issues on your provider's line or overheating equipment. Before panicking, try rebooting your router.
Modern routers often have built-in logging systems that record every connection. If you see devices with unfamiliar names (such as "Unknown Device" or brands you don't own) in the device list, it's almost a 100% guarantee that someone else is using your Wi-Fi. Identification Such devices are the first step towards solving the problem.
Login to the Beltelecom router control panel
To see the full list of connected clients, you need to log in to the router's administrative panel. This can be done from any device (computer or smartphone) that is already connected to your Wi-Fi network or connected to the router via cable. Open any browser and enter the gateway's IP address in the address bar. For Beltelecom equipment, this is most often 192.168.1.1 or 192.168.0.1.
After navigating to the address, the system will ask for a login and password. By default, the sticker located on the bottom of the device contains standard information. Typically, the login is admin, and the password can be admin, 1234 or a unique character combination specified in the "Password" or "Key" field. If you've previously changed this information and have forgotten it, you'll need to perform a factory reset.
What to do if the default password doesn't work?
If the default password information on the sticker doesn't match, it's possible that the password was changed earlier by you or the technician during setup. In this case, the only solution is a full reset using the button on the back of the router. After this, the device will return to factory settings, and you'll need to reconfigure your internet connection (PPPoE or DHCP) if this information isn't automatically retrieved from your ISP.
The interfaces of different router models may differ, but the logic for finding the "Clients" or "Status" section remains the same. In the menu, look for tabs named "Status," "Network," "WLAN," or "User Interface." These are where you'll find information about who's currently using your access point.
Checking connections on ZTE and Huawei routers
Equipment from ZTE and Huawei is among the most common in Beltelecom networks. The interface of these devices is generally intuitive, but has its own navigation quirks. After successfully logging in (often a white or blue interface with the operator's logo), you need to find the section responsible for network status.
In routers ZTE (e.g., F660, F670 models), the information you're looking for is often found under "Network" tab → "WLAN" sub-item → "User Interface" or "Associated Devices." This displays a table showing the MAC address, IP address, and name of each connected device. You can also see how many devices are currently online.
For devices Huawei (HG8245, HG8145V5 series) the path may look different: "Status" → "User Device Information." In some firmware versions, this section is located on the main page in the "My Wi-Fi" or "Home Network" widget. This makes it convenient not only to see the list but also to immediately block unwanted users.
It's important to pay attention to the connection type: wired (LAN) or wireless (WLAN). If you see an extra device in the LAN list, it means someone has physically connected to your router with a cable. This is extremely rare, but possible in private homes or offices.
Analysis of devices on Eltex and Sercomm terminals
Newer terminal models such as Eltex (NTU-2W) or Sercomm, often have an updated interface, which may feature a darker color scheme or a more modern menu structure. The search principle remains the same, but the tab names may vary. In Eltex, the path often used is: "Local Network" → "DHCP Server" → "Client List."
In the "Client List" section, you'll see a dynamic table that updates in real time. It displays all devices that have received an IP address from your router. MAC address is a unique identifier that identifies the device's manufacturer (the first six characters of the address indicate the vendor). This helps determine what kind of gadget it is: a phone, a TV, or a laptop.
If you are using a router SercommLook for the "Status" or "Statistics" section. Some Beltelecom firmware versions offer a "Wi-Fi Guest" feature that displays guest and primary users separately. Be careful: sometimes the system may display devices that were recently connected but are now offline. Look for the "Active" or "Online" status.
| Router model | Menu section | Subparagraph | Table name |
|---|---|---|---|
| ZTE F660/F670 | Network | WLAN | User Interface |
| Huawei HG8245 | Status | System Information | User Device Info |
| Eltex NTU-2W | Local Network | DHCP Server | Client List |
| Sercomm | Status | Statistics | Active Users |

Using mobile apps for control
If logging in through a browser on your phone seems complicated or inconvenient, you can use specialized network diagnostic apps. They scan the Wi-Fi airwaves and display all devices on the same local network as your smartphone. A popular tool is Fing or WiFi Analyzer.
These programs work by comparing MAC addresses. After running a scan, you'll receive a list of all devices. The app often automatically detects the device type (for example, Apple iPhone or Samsung TV) and its manufacturer. This greatly simplifies the process. identification unknown objects on your network without having to delve into complex router settings.
However, it's important to remember that mobile apps only see what your phone sees. If your router isolates clients (AP Isolation) or hides certain details, the app may not provide the full picture. Therefore, logging in through the router's web interface remains the most reliable and complete source of information.
⚠️ Please note: Device manufacturer information in apps may not update immediately. If the app shows "Unknown," use the first digits of the MAC address as a reference and compare them with manufacturer tables online.
How to block a stranger
If you detect an intruder, you should immediately block their access. The most effective way is to use the "Blacklist" or "MAC Filter" feature in your router settings. Find the filtering option in the same section where you saw the client list. Add the intruder's MAC address to the blacklist and save the settings.
Once blacklisted, the device will be unable to connect, even if it knows the password. However, the most radical and reliable method is to completely change the Wi-Fi password. Go to "WLAN" or "Wireless" → "Security" and change the "WPA PreSharedKey" (password) field. Encryption It is better to leave WPA2-PSK or WPA3, as they are the most secure.
After changing the password, all devices will be disconnected. You'll have to reconnect your devices using the new key. This ensures that anyone with the old password will no longer be able to access your device. Don't forget to disable the WPS feature, as it's often a security hole that allows passwords to be bypassed.

Measures to strengthen the security of your Wi-Fi network
To prevent a repeat incident, it's important to ensure maximum security for your network perimeter. Passwords should be complex: contain upper- and lower-case letters, numbers, and special characters, and be at least 10-12 characters long. Simple combinations like "12345678" or "qwerty" can be cracked in seconds with specialized software.
Regularly update your router's firmware. Older versions may contain vulnerabilities that allow hackers or savvy neighbors to access your settings. You can check for updates in "System Tools" → "Firmware Upgrade" or through automatic updates, if supported by your ISP.
It's also recommended to hide your network name (SSID) if you don't want your neighbors to see your access point in the list of available networks. In this case, you'll have to connect new devices manually, entering the network name and password. This creates an additional barrier to accidental connections and reduces visibility into your network.
Can a neighbor steal my password if I haven't told it to anyone?
Yes, this is possible if you have WPS (Wireless Protected Setup) enabled. Special Android apps allow you to crack the WPS PIN and find out your Wi-Fi password in just a few minutes. The password could also have been saved on a friend's device, who then connected to your network from their device, and their device could be broadcasting the network further. Always disable WPS in your router settings.
Does having a connected neighbor affect my internet speed?
Absolutely. The connection bandwidth is shared among all active users. If a neighbor starts downloading large files or watching 4K videos, your web browsing and gaming speeds can drop dramatically. Furthermore, a large number of devices puts a strain on the router's processor, which can cause it to freeze.
What should I do if I can't access my router settings?
Make sure your device is connected to this specific network, either via Wi-Fi or cable. Check that the IP address is entered correctly (192.168.1.1). If the page doesn't load, try a different browser or incognito mode. If all else fails, your PC's network settings may be corrupted or your router may be frozen—try rebooting it using the power button.
How to find out the manufacturer of a device by MAC address?
The first six characters (e.g., A4:56:30) are the device's OEM identifier (OUI). By entering these characters into any online "MAC Address Lookup" service, you can find out which brand (Apple, Samsung, Xiaomi) the device belongs to. This can help you determine whether it's a phone or, for example, a smart plug.
