How to disconnect a device from Wi-Fi via a Rostelecom router: step-by-step methods

Have you noticed other devices connecting to your Wi-Fi, or do you want to limit your child's internet access at night? In routers Rostelecom There are several ways to disconnect a device from the network, both temporarily and permanently. In this article, we'll cover all the current methods: web interface, a mobile app, and even SMS commands. It's important to understand that the procedure may vary depending on the router model (Sagemcom 2804, Sercomm RV6699, Huawei HG8347 etc.), but the general principles remain the same.

Before you begin, make sure you have access to your router's settings. You'll need the administrator login and password—these are usually found on a sticker on the back of the device (standard information: admin/admin or user/user). If you changed them but forgot, you will have to reset the router to factory settings using the button Reset (hold for 10-15 seconds).

1. Disabling the device via the router's web interface

The most reliable and universal method is to use the admin panel. It works on all router models. Rostelecom, including outdated ones. This manual is suitable for most firmware versions, but the menu appearance may differ slightly.

2. Open your browser and type in the address bar 192.168.1.1 or 192.168.0.1 (the exact address is indicated on the router sticker).
3. Enter your login and password (default see above).

Next, go to the Manage Connected Devices section. The path may vary:

• 🔹 For Sagemcom 2804/5304: Home Network → Devices → Device List
• 🔹 For Sercomm RV6699: Network → Local Network → DHCP Clients
• 🔹 For Huawei: Network → LAN → DHCP Client List

In the list you will see all the gadgets connected to your network, indicating IP addresses, MAC addresses and the device name (if defined). To disable a device:

1. Find the one you need in the list (use the name or MAC address as a guide).
2. Click the button Block, Disable or Disconnect (depending on the model).
3. Confirm the action.

Find the MAC address of the target device (found in its network settings)

Make sure you're not blocking your primary device (for example, a smartphone with access to the router)

Write down the IP address of your device in case you need to unlock it later.

Check if your device is using a static IP (such devices can bypass blocking)

5. Enter the MAC address of the device you want to block (format: XX:XX:XX:XX:XX:XX or XXXX.XXXX.XXXX).
6. Save the settings and reboot the router.

Where to find the MAC address of a device:

• 📱 Android: Settings → About phone → General information → Wi-Fi MAC address
• 🍎 iPhone/iPad: Settings → Wi-Fi → (i) next to the network → MAC address
• 💻 Windows: run the command ipconfig /all V Command line and find the line Physical address.
• 🖥️ MacOS: System Preferences → Network → Advanced → Ethernet/Wi-Fi → MAC Address

⚠️ Attention: MAC addresses can be spoofed, so this method isn't 100% guaranteed to block. For maximum reliability, combine it with IP restrictions or disabling DHCP for a specific device.

4. Disabling a device by IP address (for advanced users)

If you want to lock your device by its IP addressYou can use static IP and MAC mapping or configure firewall rules. This method is suitable if the device uses a fixed IP or you want to restrict access to certain resources.

How to bind IP to MAC (DHCP reservation):

1. Log into your router's web interface.
2. Go to Home Network → DHCP → Address Reservation (or LAN → DHCP Reservation).

• 🔧 Prevent IP address conflicts.

What to do if the device receives an IP automatically?

If your gadget uses a dynamic IP (via DHCP), its address may change after rebooting the router. In this case:

1. Bind the device's MAC address to a fixed IP in the DHCP settings (see above).

2. Or use MAC address blocking (section 3), as it is not IP dependent.

5. Disabling the device via SMS command (for routers with a SIM card)

Some router models Rostelecom (For example, ZTE MF920V or Huawei B525) support control via SMS commands. This is convenient if you have mobile internet with a SIM card and want to remotely turn off the device.

• 📱 block mac XX:XX:XX:XX:XX:XX — block the device by MAC address.
• 📱 unblock mac XX:XX:XX:XX:XX:XX — unlock the device.
• 📱 reboot — reboot the router (useful if the changes are not applied).

Example of use:

1. Send an SMS with the text devices list to the router number (indicated on the case or in the instructions).
2. Get a response with a list of devices and their MAC addresses.
3. Send a command block mac 1A:2B:3C:4D:5E:6F (replace with the actual MAC address).
4. The device will be disabled until the next unlock.

⚠️ Attention: The SMS control feature may be disabled by default. To enable it, go to the router's web interface and enable the option. SMS Control or Remote control in the section System Preferences.
