1. Checking via the router's web interface (the most reliable method)

The router's web interface is the "brain center" of your network, where you can see full list of connected devices, their IP and MAC addresses, and connection time. To access them, you'll need any browser (Chrome, Firefox, or Edge) and login information.

The standard login address is 192.168.1.1 or 192.168.0.1If none of them work, check the sticker on the back of the router: it may indicate a different IP (for example, 192.168.100.1 for some models Sercomm). The default login and password are usually admin/admin or admin/password from the sticker.

• 🔌 Enter in the address bar of your browser 192.168.1.1 and press Enter.
• 🔐 Enter your login and password (if you haven't changed them, look on the sticker on your router).
• 📊 Go to the section DHCP, Local area network or Wireless (the name depends on the model).
• 👥 Find the tab Connected devices, Client list or Hosts List.

In some firmware (for example, Sagemcom F@st 5364) the list of devices can be hidden behind a tab Status → Local NetworkIf the interface is in English, search for Attached Devices or Connected Hosts.

Check if your computer is connected to the router via cable or Wi-Fi.

Reboot the router using the button Reset for 10 seconds

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

Make sure your VPN or proxy is disabled-->

⚠️ Attention: If you see devices with unknown names in the list (for example, android-123456 or Unknown Host), this may be a sign of neighbors connecting. Don't rush to block them — First, check if they are your gadgets (smart watches, speakers or TV).

arp -a

You'll see a table with IP and MAC addresses. To filter only active connections to your router, first find out its IP (usually 192.168.1.1) and look for addresses in the same range (for example, 192.168.1.x).

IN macOS or Linux use the command:

nmap -sn 192.168.1.0/24

This command will scan the entire local network and list devices with their MAC addresses and manufacturers (if available). Install nmap it is possible through brew install nmap (macOS) or sudo apt install nmap (Linux).

• 🖥️ For Windows: arp -a | findstr 192.168.1 (replace 192.168.1 to your range).
• 🍎 For macOS: netstat -r | grep 192.168.1.
• 🐧 For Linux: ip neigh or arp -n.

MAC addresses can be checked through online services (for example, MAC Vendors Lookup) to find out the device's manufacturer. This will help identify suspicious gadgets.

• 🎮 Game consoles and TV: PlayStation, Xbox or Smart TV often have non-obvious names on the web.
• 🔌 Smart devices: light bulbs Xiaomi, columns Amazon Echo or robotic vacuum cleaners can connect automatically.
• 🕵️ MAC address: The first 6 characters indicate the manufacturer (e.g. B8:27:EB — Raspberry Pi, 78:31:C1 — Apple).
