A sudden drop in internet speed or constant lag in online games often indicates that someone else has connected to your home network. Rostelecom Provides equipment that, by default, may have standard security settings known to attackers. If you suspect your neighbors are using your channel, you should immediately check the list of active connections.
There are several effective ways to restrict access from unwanted guests. The most reliable method is to completely change the security key, but there are situations when you need to temporarily block a specific device or set up a permanent filter. In this article, we'll cover in detail how to find and disable uninvited guests through the router's web interface.
Before you begin configuring your router, make sure you have access to its administrative panel. This typically requires a cable or Wi-Fi connection, as well as a username and password to log in to the management system. Administrative access — is the key to managing your entire home network.
⚠️ Note: Router interfaces may be updated. If you don't find an exact match for a menu item, look for similar sections, such as "Wireless" or "Security."
Diagnostics: How to identify a foreign device
The first step should always be checking the current client list. Many users immediately change their password without verifying that it has been hacked, which creates unnecessary inconvenience. Modern routers Sagemcom or Eltex, which are often issued by the provider, have built-in monitoring tools.
Go to your router's status page. It displays the number of active Wi-Fi and LAN connections. If this number exceeds the number of devices you have (smartphones, TVs, laptops), there are "extra" devices on the network. Pay attention to your download speed: if you're not downloading anything and the indicators are flashing rapidly, someone is using your data.
For accurate identification, you can use third-party network scanning utilities such as Advanced IP Scanner or mobile apps like FingThey show not only IP addresses but also equipment manufacturers. This way, you can easily tell that a device labeled "Xiaomi" isn't your vacuum cleaner, but your neighbor's phone.
Accessing Rostelecom router settings
To manage connections, you need to access the "brain" of your network. Open any browser on a device connected to the router. In the address bar, enter the gateway IP address. The standard address for Rostelecom equipment is most often 192.168.1.1 or 192.168.0.1.
After entering the address, the system will request authorization. The login details are usually located on a sticker on the bottom of the device. If you've changed them previously and forgot them, you may need to reset the router to factory settings. The default login details often look like this: admin / admin or admin / unique password from the sticker.
It's important to use a browser that doesn't cache old versions of pages, or try incognito mode if the settings page doesn't load. Control interface may require entering a captcha or re-authorization when changing sections.
Method 1: Change your Wi-Fi network password
The most radical, yet most effective, way to disconnect everyone connected to Rostelecom Wi-Fi is to change the encryption key. After this, all devices, including your own, will lose connection to the router. This ensures that no old password will work again.
Find the section in the menu that is responsible for the wireless network. It may be called WLAN, Wireless or Wi-FiInside you are interested in the subsection Security or SecurityThis is where the field is located. WPA Pre-Shared Key or "Passphrase".
Create a complex password using a combination of uppercase and lowercase letters, numbers, and special characters. Avoid simple sequences like "12345678" or your date of birth. After saving the settings, the router will restart the module, and connections will be disconnected.

Method 2: Filtering by MAC Addresses
If you don't want to change the password for all devices or need to block a specific intruder while allowing others access, use MAC address filtering. Each network adapter has a unique identifier that can be blocked or allowed.
In the security settings, find the item MAC Filter or MAC address filteringYou need to switch the operating mode to "Blacklist" or "Whitelist." In the former case, you enter the offender's address, and they lose access. In the latter case, only devices on the list are granted access.
To find the MAC address of another device, look for it in the Client List in the router's status bar. Copy the value, which consists of numbers and letters separated by colons (e.g., AA:BB:CC:11:22:33), and add it to the filtering rule.
⚠️ Warning: MAC addresses can be spoofed (changed programmatically). An experienced user, upon seeing a block, can change their device's identifier to an authorized one and reconnect.
Setting up a guest network for security
Friends or family often connect to your Wi-Fi, and you don't want to share your main password. For such cases, there's a guest network feature. This is a virtual network segment isolated from your main devices (printers, NAS storage, smart home devices).
You can activate this function in the section Guest NetworkYou set a separate network name (SSID) and a separate password. They also often have a timer: you can set it to automatically disable guest access after a certain amount of time.
Using the guest area is a best practice digital hygieneEven if the guest password is leaked, your personal files and core infrastructure will remain secure. This is especially important if you have frequent visitors.
What is the difference between a guest network and a main network?
A guest network creates a separate communication channel. Devices on the guest network cannot see devices on the main network, and vice versa. This prevents access to shared folders and network printers.
Table: Comparison of access restriction methods
To help you choose the right security option, we've compared the main methods based on their effectiveness and implementation complexity. Each method has its own advantages depending on the situation.
| Method | Efficiency | Complexity | Impact on your devices |
|---|---|---|---|
| Change password | High | Low | Reconnection of all is required |
| MAC filtering | Average | Average | Not required (unless Whitelisted) |
| Guest network | High (for guests) | Low | No |
| Hiding the SSID | Low | Average | Manual name entry required |
Additional network security measures
In addition to shutting down uninvited guests, it's worth thinking about preventing future intrusions. Make sure encryption is enabled on your router. WPA2-PSK or WPA3. Obsolete standard WEP It can be hacked in a few minutes by any schoolchild with a phone.
It is also recommended to disable the function WPSIt's designed for quick connection without entering a password, but it has critical vulnerabilities. Attackers use special programs to brute-force the WPS PIN and gain access to the network.
Update your router firmware regularly. Manufacturers patch security holes through software updates. You can check the version in the section Administration or System Tools.
Frequently Asked Questions (FAQ)
Can a neighbor steal my password if I haven't told it to anyone?
Yes, if you have a weak password or WPS enabled. The password could also have been saved on a friend's device and subsequently hacked, or you could have entered it on a Wi-Fi network with a keylogger installed.
Will a power outage reset my router?
No, a short power outage will not reset the settings. For a full reset, you need to hold the button on the case for 10-15 seconds. However, after the reset, the password will revert to the factory settings.
Does my ISP see who is connected to my Wi-Fi?
Your ISP only sees your router and the traffic passing through it. It doesn't see which specific devices (phones or laptops) are within your local network unless they access the internet directly, bypassing the router.
What should I do if I can't access my router settings?
Check if you're connected to this router's network. Make sure a proxy isn't enabled in your browser. Try a different browser or device. If all else fails, the only solution is to reset the router using the Reset button.
