We will focus on technical methods, which are provided by the provider and equipment itself.

Methods vary in complexity, from basic blocking via a mobile app to fine-tuning MAC filtering on your router. Choose the appropriate option based on your skills and the model of your equipment.

1. Go to the website lk.rt.ru and log in.
2. Select a section from the menu Services → Internet.
3. Find the tab Device management or My network (the name may differ).
4. In the list of connected gadgets, find the desired device by name or MAC address.

⚠️ Attention: Blocking via your personal account only applies to devices connected to yours tariff. If the user reconnects to a neighboring router's network, the restriction will only apply when they reconnect to your network.

2. Method: Using the Rostelecom mobile application

Official app Rostelecom (available for Android And iOS) offers an even more convenient interface for network management. The advantage of this method is the ability remote shutdown devices even when you are not at home.

⚠️ Note: Some app versions (prior to 5.2.1) may not have the device locking feature. Update the app to the latest version in the store.

Method 3: MAC filtering on a Rostelecom router

This the most reliable method, as blocking occurs at the router level. Even if the user tries to connect again, the router will automatically deny access. The downside is that access to the router's admin panel is required.

How to find the MAC address of the device you want to block:

• 🖥️ On Windows: open Command line and enter ipconfig /allThe address you are looking for will be in the line Physical address.
• 📱 On Android: go to Settings → About phone → General information → Wi-Fi MAC address.
• 🍎 On iPhone/iPad: Settings → Wi-Fi → (i) next to the network → MAC address.

Instructions for routers Rostelecom (for example Sagemcom [email\protected]_v5):

1. Open your browser and type 192.168.1.1 (or 192.168.0.1 for some models).

FAQ: Answers to frequently asked questions

Is it possible to block a user by IP address instead of MAC address?

Technically yes, but that's ineffectiveIP addresses on a local network are assigned dynamically (via DHCP), and they may change after rebooting the router or device. A MAC address is a hardcoded identifier that only changes with manual intervention.

What to do if an unknown device connects again and again?

It's likely that someone on your network is deliberately trying to bypass the block. In this case:

1. Change your Wi-Fi password to a more complex one.
2. Turn on hiding SSID (the network will not be visible in the list of available ones).
3. Set up Wi-Fi operating schedule (for example, turn off the network at night).
4. Check your router for vulnerabilities (update firmware).

Is it possible to find out what device is hidden behind a MAC address?

Partially. The first 6 characters of the MAC address (the so-called OUI) indicate the manufacturer. For example:

• 00:1A:79 — Samsung
• 3C:5A:B4 — Google (including Nest And Android-devices)
• B8:27:EB — Raspberry Pi

You can check your OUI on websites like macvendors.comHowever, it is impossible to determine the exact device model based on MAC.

Is it legal to block neighbors who are "stealing" my Wi-Fi?

Yes, if we are talking about your personal networkYou have every right to restrict access to your internet. However, if a neighbor connects intentionally (for example, hacking your password), this may already qualify as unauthorized access to computer information (Article 272 of the Criminal Code of the Russian Federation). In this case, you can file a police report, attaching the router logs.

How do I permanently block a device so it can never connect again?

The most reliable way is a combination of MAC filtering and password changing:

1. Add the device's MAC address to the router's blacklist.
2. Change your Wi-Fi password to a complex one (12+ characters).
3. Disable the feature WPS (it is vulnerable to hacking).
4. Turn on MAC filtering in mode Allow only specified devices and add only your gadgets to the whitelist.
