Top 3 programs for Windows And macOS:

Example of working with Wireless Network Watcher:

1. Download and run the program (no installation required).
2. Click Start Scanning.
3. In 10-30 seconds you will see a full list of devices indicating:

5. How to block other people's devices on a Rostelecom router

Discovered a suspicious device on your network? Don't panic—there are several ways to block it.

Method 1: Via the router's web interface

1. Go to your router settings (192.168.1.1).
2. Go to the section Security → MAC Filtering (or Wireless → MAC Filter).
3. Add the MAC address of someone else's device to the blacklist.
4. Save the settings and reboot the router.

Method 2: Change your Wi-Fi password

The most radical, but effective method:

1. In the router's web interface, find the section Wi-Fi → Security Settings.
2. Change your password to a complex one (use WPA2-PSK or WPA3).
3. Example of a strong password: k7#pL9!vR2@qW4$e (12+ characters with numbers, letters and special characters).
4. Save the changes - all devices will be disconnected, and you will have to reconnect your gadgets.

Method 3: Hiding the network name (SSID)

This won't protect you from experienced hackers, but it will reduce the number of accidental connections:

1. In the Wi-Fi settings, find the option Hide SSID (or Hide SSID).
2. Activate it and save the settings.
3. Now your network will not be displayed in the list of available ones, and you can only connect to it manually, knowing the name.

6. How to protect your Wi-Fi from future hacking

To avoid problems with third-party connections in the future, follow these recommendations:

Basic security settings:

• 🔒 Use WPA3 (or WPA2-PSK, if WPA3 is not supported). WEP And WPA are outdated and easily hacked.
• 🔄 Change your Wi-Fi password regularly (every 3-6 months).
• 📵 Turn off WPS (Wi-Fi Protected Setup) - This feature is vulnerable to brute-force attacks.

Additional measures:

• 📋 Turn on MAC address filtering and add only your devices to the whitelist.
• 🕒 Set up Wi-Fi operating schedule (for example, turning off at night), if this feature is supported by your router.
• 🛡️ Update your router firmware to the latest version (section System → Software Update).

For advanced users:

• 🌐 Create guest network for visitors with a separate password and limited access to local resources.
• 📊 Set up traffic monitoring through programs like GlassWire or PRTG Network Monitor.
• 🔍 Regularly scan your network for vulnerabilities using Nmap or Acunetix.

⚠️ Attention: Rostelecom routers manufactured before 2019 (e.g., Sagemcom F@st 1744) may have firmware vulnerabilities that allow MAC address filtering to be bypassed. If your device is older than 3 years, consider replacing it or installing alternative firmware (e.g., OpenWRT).

7. Common mistakes and their solutions

Users often encounter difficulties when checking connected devices. Let's look at common issues and how to resolve them.

Problem 1: I can't access the router's web interface.

• 🔌 Check if your computer is connected to the router via cable or Wi-Fi.
• 🔄 Reboot your router (unplug it for 30 seconds).
• 🛠️ Try a different browser (Chrome, Firefox, Edge).
• 📡 Make sure you are entering the correct IP address (check the sticker on the router).

Problem 2: The list of devices displays unknown devices with the names "Android-XXXX" or "iPhone"

These could be:

• 📱 Devices of guests who have connected previously and have not disconnected;
• 🔄 Your old phones or tablets that you forgot about;
• 🤖 Smart devices (speakers, light bulbs, cameras) connected to Wi-Fi.

Check MAC addresses via macvendors.com - this will help identify the manufacturer.

Problem 3: After changing the password, some devices do not connect

• 🔄 Restart your router and the problematic device.
• 📱 On your device, remove the network from saved connections and reconnect.
• 🛠️ Check if the device supports the selected encryption type (for example, older printers may not work with WPA3).

FAQ: Answers to frequently asked questions

Is it possible to find out who is connected to my Wi-Fi if I'm not an admin?

No. Only users with access to the router settings (web interface or mobile app) can view the device list. If you don't know the password for the admin panel, contact the person who set up the network.

What should I do if my neighbor hacked my Wi-Fi and refuses to disconnect?

First, change your Wi-Fi password and enable MAC address filtering. If your neighbor continues to connect, this could be a sign of a more serious attack (such as MAC spoofing). In this case:

1. Update your router firmware;
2. Reset your router to factory settings;
3. Contact support Rostelecom to check for vulnerabilities.

As a last resort, consider purchasing a new router with support WPA3.

Can a Rostelecom router block suspicious devices on its own?

Standard routers from Rostelecom do not have an automatic locking function. However, some models (for example, Keenetic or ASUS, if you purchased them separately) support:

• 🛡️ Built-in firewall;
• 🚨 Notifications about new devices;
• 📊 Monitoring unusual traffic.

For basic routers from your provider, you will have to manually check the list of devices.

How do I know if my Wi-Fi has been hacked?

Signs of unauthorized access:

• 🐢 A sharp drop in internet speed;
• 🔋 The router's battery drains quickly (if it has a battery);
• 📡 Unknown devices in the connection list;
• 💸 Unexplained increase in traffic (check in your personal account) Rostelecom).

If you notice any of these signs, check your network immediately.

Is it legal to connect to someone else's Wi-Fi?

According to Article 272 of the Criminal Code of the Russian Federation ("Unauthorized access to computer information"), an unauthorized connection to someone else's network may be classified as an offense if:

• 🔓 Access was obtained without the owner’s consent;
• 💰 Material damage was caused (for example, exceeding the traffic limit);
• 📄 Technical means were used to hack the account (for example, brute-force password attacks).

In most cases, neighbors who connect unknowingly are not held responsible. However, if someone intentionally hacks your network, it may be grounds for a police report.
