How to see which devices are connected to my MTS Wi-Fi: all methods

Instructions for Windows:

1. 🖥️ Click Win + R, enter cmd and press Enter.
2. 📜 Enter the command:
   

   arp -a

   Click Enter.

3. 🔍 In the list, find lines with IP addresses from your subnet (usually 192.168.x.x).
4. 🔄 To see active connections, first run:
   

   ping 192.168.1.255

   And then enter again arp -a.

For macOS/Linux use commands:

nmap -sn 192.168.1.0/24

or

arp-scan --localnet

(you will need to install the utility nmap or arp-scan via package manager).

As a result, you will receive a list of IP and MAC addresses. To identify devices, copy the MAC address and check it using the service. MAC Vendors (as mentioned earlier).

4. Checking via third-party applications

If the previous methods seem complicated, you can use specialized network scanning programs. They automatically detect all connected devices, displaying their names, manufacturers, and even their bandwidth usage. Here are the most reliable options:

How to use Fing (for example Android):

1. 📱 Install the app and open it.
2. 🔍 Click Scan — the program will automatically find all devices on your network.
3. 📋 In the list, you will see the names of the gadgets, their IP, MAC, manufacturer, and even the model (if identified).
4. 🚫 To block a device, copy its MAC address and add it to the blacklist in the router settings (as described in the first section).

Fing also shows which devices active right now, and which ones have been connected previously. This helps identify "sleeping" gadgets that might automatically connect to your network (for example, smart speakers or fitness trackers).

5. How to identify "unnecessary" devices and block them

Did you find any unfamiliar devices on the list? Don't panic—first, make sure they really are yours. Here's what might be on your network:

• 📺 Smart TV, prefixes (Apple TV, Xiaomi Mi Box), game consoles (PlayStation, Xbox).
• 🔊 Smart speakers (Yandex Station, Amazon Echo, Google Nest).
• 💡 Smart home devices: light bulbs (Xiaomi Yeelight), sockets (TP-Link Tapo), robotic vacuum cleaners.
• 📱 Old phones or tablets that haven't been used for a long time but remain connected.

If you are sure that the device is not yours, proceed as follows:

1. 🔍 Compare the MAC address with the list manufacturers (as described earlier). For example, if the address starts with B8:27:EB, this device Raspberry Pi; 78:31:C1 — Apple; 50:65:83 — Xiaomi.
2. 📵 Check if your neighbors are connected to your network by mistake (for example, if you have the same Wi-Fi names).
3. 🚫 Block the device via the router's web interface (section MAC Filtering or Blacklist).
4. 🔒 Change your Wi-Fi password to a more complex one (at least 12 characters, with numbers and special characters).

If other people's devices reappear, your password may have been compromised. In this case:

• 🔄 Reset your router to factory settings (button Reset on the back panel).
• 🔐 Set a new administrator password to access the router settings.
• 🛡️ Update your router firmware (section System Tools → Firmware Upgrade).

6. Limiting the number of devices in the MTS router

If your tariff MTS If you limit the number of connected devices (for example, "up to 10 devices"), you can configure the router to automatically block unnecessary connections. To do this:

1. 🌐 Log in to your router's web interface (as described in the first section).
2. 🔧 Go to the section Wi-Fi → Security Settings or DHCP → DHCP Settings.
3. 📊 Find the option Maximum number of clients or Limit DHCP Leases.
4. ✏️ Set the desired number (for example, 10) and save the settings.

You can also reserve IP addresses for your devices so they always receive the same address. This will help track connections and block unfamiliar devices. To do this:

1. In the section DHCP find Address Reservation or Address reservation.
2. Add the MAC addresses of your devices and assign them fixed IPs.
3. Disable automatic IP assignment for unknown devices.

7. Common problems and their solutions

You may encounter difficulties when checking connected devices. Here are the most common ones and how to fix them:

If none of these methods work, the problem may be with the router itself. In this case:

• 🔄 Reboot your router (unplug it from the power outlet for 30 seconds).
• 🔧 Reset to factory settings (button Reset).
• 📞 Contact support MTS by phone 0890 (for home Internet) or via chat in the application.

8. Additional Wi-Fi security tips from MTS

Even if you don't have any foreign devices on your network, follow these guidelines to avoid problems in the future:

• 🔐 Use a complex password For Wi-Fi: at least 12 characters, with capital letters, numbers and special characters (e.g. MtsWiFi_2026!Kot). Don't use obvious combinations like qwerty123 or date of birth.
• 🛡️ Enable WPA3 encryption (if your router supports it). If not, use WPA2-PSK (but not WEP or WPA).
• 📵 Disable WPS - This protocol is vulnerable to hacking, even if you don't use it.
• 🔄 Update your firmware regularly router (section System Tools → Firmware Upgrade).
• 📡 Change the network name (SSID) to something unique that does not contain personal information (e.g., not Ivanov_kv5, A BlueMoonWiFi).
• 👀 Disable remote control router (section Remote Management), if you do not use this feature.
• 📱 Set up a guest network For friends, it is isolated from the main one and does not provide access to your devices.

2. 🔐 Change the router administrator password (do not leave it admin/admin).
3. 🛡️ Set a new Wi-Fi password and turn it on WPA3.
4. 📋 Check the list of connected devices and block unfamiliar ones.
5. 📞 Contact support MTS, if you suspect that the problem is on the provider's side.

Important: If you see gadgets with MAC addresses starting with in the list of devices 00:00:00, FF:FF:FF or 00:50:C2This could be a sign of spoofing. In this case, immediately change your Wi-Fi password and update your router firmware.
