How to check who's connected to my ByFly (Beltelecom) Wi-Fi on a Huawei router: a complete guide

Do you suspect that your Wi-Fi from ByFly (operator Beltelecom) Did strangers connect? With routers Huawei, which are often provided by providers in Belarus, you can check the list of devices in several ways—from standard tools to advanced utilities. But there are some nuances: the admin panel interface may differ depending on the model (Huawei HG8245H, HG633, EchoLife etc.), and some methods require administrator rights.

In this article we will analyze all working methods — from simple browsing through a browser to traffic analysis using WiresharkWe'll also find out how to distinguish legitimate devices from fakes, and what to do if you discover someone else's gadgets. Important: ByFly routers often have control of connected devices disabled in the mobile app by default—we'll cover this separately.

1. Checking via the Huawei router's web interface

The most reliable and universal method is to access the router's control panel through a browser. This doesn't require any additional software, but you will need the admin login and password (usually found on a sticker on the device).

Step-by-step instructions:

1. Connect to the network ByFly_XXXX (or your custom SSID) from a computer or smartphone.
2. Open your browser and enter in the address bar 192.168.1.1 or 192.168.100.1 (for some models Huawei from ByFly). If it doesn't open, try http://home.gateway.
3. Enter your login and password (by default it is often admin/admin or telecomadmin/admintelecom).
4. Go to the section DHCP → DHCP Clients List or Network → WLAN → Connected Devices (the name depends on the firmware).

In the table you will see a list of all connected devices, indicating:

• 🔹 IP addresses (For example, 192.168.1.102)
• 🔹 MAC addresses (unique species identifier 00:1A:2B:3C:4D:5E)
• 🔹 Host name (if the device broadcasts it, for example, iPhone-12-Pro)
• 🔹 Connection type (Wi-Fi or Ethernet)

⚠️

Attention: If the list contains devices with unknown MAC addresses, don't rush to block them. Some smart TVs, printers, or IoT gadgets (e.g., Xiaomi Mi Home) may appear under technical names such as ESP_123456.

2. Using the Huawei AI Life mobile app

Official app Huawei AI Life (previously Huawei HiLink) allows you to control your router from your smartphone, but with a caveat: not all ByFly models support full functionality. Still, it's worth a try.

How to check connected devices:

1. Download Huawei AI Life from App Store or Google Play.
2. Register or log in with your account Huawei ID.
3. Click Add a device → Router and select your model.
4. Connect to the router according to the instructions (you will need to scan the QR code from the sticker or enter the password).
5. In the main menu, select Network Management → Connected Devices.

🔍 What is important to know:

• 📱 The app may not show All devices, if the router has old firmware (relevant for Huawei HG8245H from ByFly until 2022).
• 🔄 Data is updated with a delay of up to 5 minutes - for an up-to-date list, it is better to use the web interface.
• 🚫 The device blocking feature via the app may be disabled by your provider.

3. Analysis via the command line (for advanced users)

If the web interface is not available or you prefer to work through the terminal, you can get a list of connected devices using commands arp And pingThe method works on Windows, macOS And Linux.

Instructions for Windows:

ping 192.168.1.255
arp -a

Explanations:

• 📶 Team ping 192.168.1.255 Sends a broadcast request to all devices on the local network.
• 📋 Team arp -a displays the ARP cache table, which lists the IP and MAC addresses of devices with which your PC has exchanged traffic.

🔹 Example output:

Interface: 192.168.1.100 --- 0x12
Internet Address Physical Address Type
192.168.1.1 00-1a-2b-3c-4d-5e dynamic
192.168.1.101 a1-b2-c3-d4-e5-f6 dynamic

⚠️

Attention: This method will only show devices that have recently communicated with your computer. For a complete list, it's best to combine it with other methods or use a network scanner (see Section 5).

4. Viewing through your ByFly personal account (limited functionality)

Beltelecom does not provide a full list of connected devices in your personal account, but you can see them there active sessions (For example, for plans with a limited number of gadgets). Here's how to do it:

Steps:

1. Go to the website https://my.byfly.by and log in.
2. Select a section Services → Internet.
3. Click on your tariff plan (for example, ByFly Home 100).
4. Scroll down to the block Usage statistics — the number of active connections may be displayed there.

📌 Limitations of the method:

• 🔢 Doesn't show specific devices, only their quantity.
• 🕒 Data is updated every 1–2 hours.
• 🚫 Doesn't work for plans without a limit on the number of gadgets (for example, ByFly Home Unlimited).

How to bypass ByFly personal account restrictions?

If your personal account doesn't contain information about connected devices, the only reliable way is to use the router's web interface or third-party utilities. Beltelecom intentionally limits this function to reduce the load on the monitoring system.

5. Third-party network scanning programs

If standard methods don't help, use specialized utilities. They scan the local network and display all active devices, including hidden ones.

🔍 How to use Fing (using a smartphone as an example):

1. Install the application and open it.
2. Click Scan — the program will automatically detect your network.
3. After 10-20 seconds, a list of devices will appear with the manufacturer indicated (for example, Apple Inc., Samsung Electronics).
4. Click on an unknown device to see its MAC address and connection history.

⚠️

Attention: Programs like Wireshark They require administrator rights and may be blocked by antivirus software. Do not use them on your work computer without permission from your IT department.

6. How to distinguish your device from someone else's

Found an unknown MAC address in the list? Don't rush to block it. Here's how to determine whether it's your device or someone else's:

🔎 Identification methods:

• 📱 Check manufacturer by MAC: The first 3 bytes of the MAC address (e.g. 00:1A:2B) indicate the vendor. Use the service https://macvendors.comto find out who owns the address (Apple, Samsung, Xiaomi, etc.).
• 🔄 Turn off all your gadgets: Turn off Wi-Fi on phones, laptops, TVs and see which devices remain on the list.
• 🕒 Check your connection time: If the device appears at night or in your absence, this is a clear sign of "exposure".
• 📡 Use hostname: Devices with names like android-123456 or iPad-Pro most likely yours, and Unknown_Device - suspicious.

📊 Example of MAC address decoding:

MAC prefix	Manufacturer	Device type
3C:22:FB	Apple	iPhone, MacBook, iPad
78:31:C1	Xiaomi	Smartphones, smart lamps, robot vacuum cleaners
00:0A:F7	Samsung	Telephones, televisions, laptops
B8:27:EB	Raspberry Pi	Microcomputers, servers

7. What to do if you find someone else's device

Found a suspicious device on the list? Follow these steps:

🛡️ Blocking steps:

1. Change your Wi-Fi password:
   • Go to the router's web interface (192.168.1.1).
   • Go to WLAN → Security Settings.
   • Set a new password (at least 12 characters, with numbers and special characters).
   • Save your settings and reconnect your devices.
2. Enable MAC filtering:
   • In the section WLAN → MAC Filter Add only your devices' MAC addresses to the whitelist.
   • Activate the option Enable MAC Filter.
3. Update your router firmware:
   • In the section System Tools → Firmware Upgrade Check if the version is up to date.
   • If an update is available, install it (this will patch the vulnerabilities).

Check the guest network:

• Make sure the guest network is disabled (WLAN → Guest Network).
• If it is enabled, disable it or set a separate password.

⚠️

Attention: If after changing the password someone else's device appears on the network again, it is possible that your router has been hacked through a vulnerability (for example, CVE-2017-17215 for older models Huawei). In this case, a factory reset or hardware replacement is required.

FAQ: Frequently asked questions about connected devices

🔍 Why does "Unknown" or "Reserved" appear in the device list?

This could be:

• A smart device (lamps, sockets, cameras) that does not broadcast its hostname.
• Guest device connected via WPS (if the function is enabled).
• Network printer or media player (eg. DLNA server).

To identify such a device, check its MAC address using the service macvendors.com.

🔄 Is it possible to see the connection history (who was online a week ago)?

Standard routers Huawei ByFly doesn't save your connection history. To do this, you need:

• Advanced firmware like OpenWRT (not officially supported) Beltelecom).
• Third-party monitoring programs (eg GlassWire for Windows).
• Routers with logging support (eg. MikroTik).

📵 What should I do if I can't access my router settings (192.168.1.1 won't open)?

Try:

1. Reset the router using the button Reset (hold for 10 seconds).
2. Connect via cable (Wi-Fi may be disabled in settings).
3. Check the gateway IP address using the command ipconfig (Windows) or ifconfig (macOS/Linux).
4. Contact ByFly support - your router may be blocked by your provider.

🔒 How to protect your Wi-Fi from hacking after blocking other people's devices?

Recommendations:

• Turn it off WPS in the router settings (WLAN → WPS Settings).
• Use encryption WPA3 (if supported) or WPA2-AES.
• Hide network SSID (WLAN → Basic Settings → Hide SSID) - this is not protection, but it will reduce the number of accidental connections.
• Set up Firewall on the router to block suspicious requests.

📡 Why does someone else's device remain connected to the network even after changing the password?

Possible reasons:

• The device is connected via cable (Ethernet), not Wi-Fi.
• Hacking through a router vulnerability (for example, DNS Changer or UPnP exploit).
• Your neighbor is using repeater, which clones your network.
• There is a smart device on the network (for example, Amazon Echo), which automatically reconnects.

Solution: Perform a full reset of the router and configure it again.
