Having other devices connect to your home network is quite common, especially in apartment buildings. Neighbors may be using your Internet channel Downloading files, watching videos, or downloading games significantly reduces your connection speed. If you notice video conferences are lagging and pages are taking a long time to load, it might be time to limit access to your hotspot.
For the company's subscribers Rostelecom The procedure for blocking uninvited guests depends on the model of the equipment installed. In most cases, the provider provides routers of the following brands: Sagemcom, Eltex, Huawei or ZTEAll of these devices allow you to manage the list of connected clients, but the settings interfaces may differ significantly. It's important to understand that simply changing the password may not provide immediate results if your neighbors' devices still have old access settings.
In this article, we'll explore not only methods for forcibly disabling specific devices, but also methods for reliably protecting your network from repeated intrusions. You'll learn how to use MAC filtering, how to find hidden security settings, and what steps to take if the router's standard interface doesn't allow you to block the device. We'll also explore the features of the proprietary smartphone app, which simplifies network administration.
Identifying connected devices on the network
Before resorting to drastic blocking measures, it's important to determine exactly who is using your Wi-Fi. It's common for users to forget about connected smart TVs, set-top boxes, or gadgets belonging to weekend guests. The first step is to log into your router's control panel, which displays a complete list of active connections.
To access the settings, open any browser on a device connected to the network and enter the router's IP address in the address bar. The standard address for the equipment Rostelecom most often is 192.168.1.1 or 192.168.0.1After entering the address, the system will ask for your username and password to access the administrative panel. This information is usually located on a sticker on the bottom of the router, unless you've changed it previously.
After logging in, you'll need to find the network monitoring section. This section may have different names depending on your router model. Look for menu items labeled "Status," "Device List," "Client List," or "DHCP Clients." This list will display all devices currently receiving an IP address from your router. Pay attention to the number of connections: if there are more connections than your personal devices, then unauthorized access has been confirmed.
To accurately identify the "intruder," check the MAC addresses of the devices against your list of devices. A MAC address is a unique identifier for a network interface, which is a set of 12 hexadecimal digits (e.g., A1:B2:C3:D4:E5:F6). Manufacturers typically indicate part of the MAC address on the device's body or on a sticker under the smartphone's battery.
Blocking devices via the router's web interface
The most common and effective way to disconnect someone from Wi-Fi is to use the router's built-in functionality. The web configurator interface allows you to not only view the list but also manage access rights for each MAC address. However, this functionality may be hidden in different tabs depending on the firmware version.
Let's look at the steps for the most popular terminal models offered by your provider. If you're using a router Sagemcom or Eltex, you need to go to the "Local Network" section and find the "User Access" or "Access Control" subsection. This displays a table of all active clients.
To block a specific device, follow these steps:
- 🔍 Find the MAC address of the intruder in the list and copy it.
- 🚫 Go to the "Security" or "Filter" menu.
- 📝 Create a new rule, selecting the "Blacklist" or "Deny" mode.
- ✅ Paste the copied MAC address and save the settings by clicking the "Apply" or "Save" button.
After applying the settings, the router will disconnect from the specified device. Even if the neighbor tries to connect again with the password, the router will ignore requests from the blocked MAC address.
Setting up MAC filtering and whitelisting
There is a more rigorous and reliable method of protection known as White List (Whitelist). Unlike a blacklist, where we block specific addresses, a whitelist allows connections only to devices you manually specify. All other connection attempts, even with the correct password, will be rejected.
To activate this mode, go to Wireless Settings and find "MAC Filter" or "Access Control." Switch the filter mode from "Deny" to "Allow." Then, add the MAC addresses of all your trusted devices, including smartphones, laptops, TVs, and smart speakers, to the rules table.
⚠️ Caution: Be extremely careful when setting up a whitelist. If you add only one device to the list (for example, the computer you're using to configure the router) and then apply the settings, your smartphone will lose Wi-Fi access. It's best to enter the MAC addresses of all devices in advance and write them down on paper.
The process of adding devices to the whitelist is as follows:
- 📱 Go to the Wi-Fi settings on each of your devices and find the MAC address (often hidden in the "About phone" or "Status" section).
- 📥 In the router interface, click "Add New" in the MAC filtering section.
- 🔢 Enter the address manually or select from the list of already connected devices, if this option is available.
- 🔒 Activate the filter and make sure all your devices continue to work.
This method ensures that none of your neighbors will be able to connect to your network, even if they somehow learn your password. The only downside is that you have to manually add each new device (for example, when guests come over), which can be inconvenient.
What to do if you blocked yourself?
If you lose access to your router after enabling filtering, the only solution is to reset the device. To do this, press and hold the Reset button for 10-15 seconds. The router will return to factory settings, the password will be reset to the one on the sticker, and filtering will be disabled.
Using the "My Rostelecom" application
Modern routers provided by providers support remote management via a proprietary mobile app. This significantly simplifies network monitoring, as it eliminates the need to enter IP addresses and memorize complex menu paths. My Rostelecom (or RT-Keeper (for older models) allows you to control access directly from your smartphone screen.
After logging into the app (usually an account linked to a contract is required), go to the "My Network" or "Wi-Fi" section. Here, all connected devices are displayed graphically. The app often highlights suspicious devices or displays channel load in real time.
To disable a user through the app:
- 📲 Open the list of devices in the main menu of the application.
- 👆 Click on the icon or name of the device you want to block.
- 🛑 Select the "Block" or "Restrict access" option.
- 🔄 Confirm the action; the device will be disabled immediately.
The advantage of using an app is the ability to quickly respond to changes. You can temporarily block access and then unblock it with a single tap, without having to delve into the router's settings. Additionally, the app often allows you to create guest networks with limited access times.
Changing the password and encryption type
If you don't want to mess with MAC addresses or have too many of them, the simplest and most effective way to "kick everyone out" at once is to change your wireless network password. This will force the connection to end on all devices, and only those you share the new password with will be able to reconnect.
To change your password, go to the "WLAN" or "Wireless" section of your router settings. Find the "Pre-Shared Key," "WPA Password," or "Security Key" field. Create a strong password that includes mixed-case letters and numbers. It's also crucial to check the encryption type: it should be set to WPA2-PSK or WPA3Old WEP and WPA standards can be easily cracked with special programs in a few minutes.
After changing the password and saving the settings, the router will restart the wireless module. All devices attempting to connect with the old password will receive an authorization error. This is guaranteed to disconnect all neighbors, but will require you to update the password on all your personal devices.
| Parameter | Recommended value | Description |
|---|---|---|
| Security Mode | WPA2-PSK / WPA3 | The most secure encryption standard available today. |
| Encryption | AES | A hack-resistant encryption algorithm (do not use TKIP). |
| WPS | Disabled | The quick connect feature is often a security hole. |
| SSID Broadcast | Enabled | Network visibility. Hiding your name doesn't provide complete protection. |
Additional network security measures
Beyond the basic settings, there are a number of additional measures that can help secure your communication channel. One of the most vulnerable features in routers is WPS (Wi-Fi Protected Setup). It allows you to connect to a network without entering a password, simply by pressing a button on the router or using a PIN code. Attackers can brute-force the WPS PIN code, gaining access to your network even with a complex password.
It's recommended to completely disable the WPS function in your router settings. This option is typically located under "WLAN" -> "WPS." Set the switch to "Disable." This will close one of the most common loopholes for unauthorized access.
It's also worth paying attention to signal strength. If your router is located near a window and beams its signal across the entire neighborhood, your Wi-Fi could be used by neighbors outside your home. In the Wireless Settings, you can reduce the Tx Power from 100% to 70% or 50%. This will reduce the signal's range, making it unavailable to distant neighbors, while maintaining stability within your apartment.
⚠️ Note: Router interfaces are constantly being updated. The layout of menu items may vary depending on the firmware version installed on your device. Sagemcom, Eltex or HuaweiIf you cannot find the functions described, check the official documentation for your specific model on the manufacturer's website.

Frequently Asked Questions (FAQ)
Can my neighbor steal my internet if I hide my network name (SSID)?
Hiding the network name (SSID Broadcast) isn't foolproof. Although the network won't appear in the general list of available Wi-Fi networks on phones, an experienced user can easily detect a hidden network using specialized software based on its data packets. Furthermore, hiding the SSID can cause connection issues for your own devices, which will constantly be searching for this network in the background.
What should I do if I forgot the password for my router settings (admin)?
If you haven't changed your password, try the standard combinations: admin/admin, admin/1234 Or the data from the sticker on the bottom of the device. If the password has been changed and lost, a full reset will help. To do this, press the Reset button on the powered-on router with a thin object and hold it for 10-15 seconds until the lights blink. This will restore the router to its factory settings.
Does the number of connected devices affect internet speed?
Yes, it does have a direct impact. The connection bandwidth is shared among all active users. If your neighbor is downloading a large file or watching a 4K video, your page loading and app browsing speeds may drop to a crawl as the router distributes packet queue resources.
Is it safe to use third-party Wi-Fi unblocking software?
Using Wi-Fi scanners and hackers on your router is not recommended. They may contain malicious code or expose vulnerabilities in your own network. To manage access, use only official tools built into your router or your provider's app.
