Slow internet speeds and intermittent connection interruptions are often the first warning signs that your home network has been accessed by unauthorized users. Owners of Rostelecom equipment, whether modern models Sagemcom or older versions ZTE, are required to regularly monitor the list of authorized clients. This is not just a matter of saving traffic, but also a basic measure. information security your digital space.
Modern routers offer powerful tools for monitoring network activity, but access to these features is hidden behind the admin interface. Many users don't even realize they can check which devices are consuming their network bandwidth at any time. Understanding how they work local network will allow you to instantly respond to suspicious activity.
In this article, we'll detail the steps for checking connected subscribers on various terminal models. You'll learn how to distinguish your devices from others by MAC addresses and discover how to effectively block access to uninvited guests. Proper filtering setup is the foundation for the stable operation of your WiFi.
Login to the Rostelecom router control panel
The first and mandatory step for any diagnostic is to log in to the device's web interface. To do this, connect your computer or smartphone directly to the router via a cable or wireless connection. Make sure the indicator LAN or WiFi on the body blinks, confirming the physical connection between the devices.
Open any browser and enter the gateway's IP address in the address bar. The standard address for Rostelecom equipment is 192.168.1.1 or 192.168.0.1If the standard address is not suitable, it can be found on a sticker on the bottom of the device or found out through the command line by entering the command ipconfig and find the line "Default gateway".
After navigating to the address, the system will ask for login credentials. By default, on routers Sagemcom And ZTE login and password are used adminIf you have previously changed this data and forgot it, you will need to perform a full reset by pressing the button Reset on the back panel.
⚠️ Note: Firmware interfaces may differ depending on the software version. If the standard menu paths don't match, look for sections with similar names, such as "Status," "Condition," or "Clients."
Search for a list of connected devices in the interface
After successful authorization, you'll be taken to the main page or the advanced settings menu. The interface may be green, blue, or white, depending on your terminal model. You'll need to find the tab that displays current network activity. It's usually called LAN, Home Network or Net.
Within this section, look for a subsection with a list of active hosts. It may be called "Client List," "DHCP Lease," or "Statistics." This is where you'll find a table containing the IP addresses, MAC addresses, and names of all devices currently accessing your router.
Pay attention to the number of rows in the table. If you see a device you can't identify (for example, "Unknown" or a smartphone name), this is cause for concern. Modern systems often assign names automatically, but not always correctly, so it's best to check with MAC address.
Why might device names not match?
The device's network name is often taken from the device's settings or specified by the chip manufacturer. For example, an iPhone might appear as "iPhone" or "Apple Device," while a Samsung TV might appear as "DLNA Device."
List Analysis: How to Distinguish Your Devices from Others
The most reliable method of identification is checking the MAC address. This is a unique identifier for a network interface, consisting of 12 hexadecimal characters separated by colons or hyphens. The first six characters (OUI) identify the hardware manufacturer, helping to identify the connected device.
Walk around your home and collect the MAC addresses of all your gadgets. On Android smartphones, this information can be found in the Settings → About phone → General informationOn iPhone the path is through Settings → General → AboutOn a Windows PC, use the command ipconfig /all in the command line.
Compare the resulting data with the list in your router. If you see a device named "Android-xyz" in the table, but you don't have any Android smartphones, or if the number of active connections exceeds the number of devices you have, then unauthorized access has been obtained. Pay particular attention to devices with the connection type Wireless.
| Manufacturer (OUI) | Probable device | What to look out for |
|---|---|---|
| Apple, Inc. | iPhone, iPad, MacBook | Often hide the real MAC by using random addresses |
| Samsung Electronics | TV, smartphone, refrigerator | Check if your neighbor's Smart TV has connected |
| Intel Corporate | Laptop, PC network card | Usually stationary devices, easy to identify |
| Unknown / Generic | Chinese gadgets, IoT devices | High risk: may contain a hidden miner or camera |
This means that the same device may appear in the router's list under different addresses each time it reconnects, unless you choose to use a real address.
Blocking uninvited guests with a MAC filter
If you have detected an intruder, the most effective method of protection is to set up MAC filteringThis feature allows you to create a whitelist of devices that are allowed to connect, or a blacklist of those that are strictly denied access. Configuration is performed in the section WLAN or Wireless network.
Select "Whitelist" mode for maximum security. In this case, you'll need to manually enter the MAC addresses of all your trusted devices. Once the settings are applied, any new device, even with the WiFi password, will be unable to access the network.
☑️ Setting up a whitelist
An alternative, less radical method is "Blacklist" mode. Here, you simply add the offender's address to the block list. However, this method is less secure, as the attacker can change the MAC address on their device and bypass the block.
⚠️ Caution: Be careful when enabling whitelist filtering. If you enter the incorrect MAC address of your primary device or make a character error, you will lose network access and will have to connect to the router via cable or reset it.
Change your password and strengthen your WiFi network security
While blocking your network, you should change your wireless network password. Even if you've kicked out the intruder, they still know your old encryption key and may try to connect again. Go to WLAN Security or Security.
Make sure the encryption method is selected WPA2-PSK or WPA3Using an outdated protocol WEP or open network (None) makes your traffic vulnerable to interception even without a password. The password must be complex and contain mixed-case letters, numbers, and special characters.
After changing your password, all your devices will be disabled. You'll need to re-enter the new key on every smartphone, tablet, and laptop. This is a small price to pay to ensure your neighbors won't be using your internet connection.
It is also recommended to disable the function WPS (Wi-Fi Protected Setup). Despite the convenience of connecting with the push of a button, this protocol has known vulnerabilities that allow someone to brute-force the PIN and gain network access in a matter of hours.
Diagnostics via the My Rostelecom mobile app
For owners of modern routers Sagemcom And ZTE, issued by the provider, there is a convenient way to control it through the official application My RostelecomThis method does not require entering IP addresses or knowledge of complex terminology; the interface is adapted for the average user.
Log in to the app using your personal account login. The "Equipment" or "My WiFi" section displays the current network status. You can see a list of connected devices, their names, and the ability to quickly block any of them with a single tap of the "Stop" or "Block" button.
The mobile app also allows guests to connect via QR code, eliminating the need to dictate a complex password. However, keep in mind that the management function is only available if the router is linked to your account and online. For more detailed filter customization, it's best to use the web interface.
What should I do if the list of devices is constantly updated?
If you're seeing devices constantly appearing and disappearing, you may have the guest network feature enabled. Check your settings. Guest NetworkThis could also be a sign of smart devices (IoT) that periodically go to sleep and wake up, changing their status in the DHCP list.
Can my neighbor see my device list?
No, the list of connected clients is only visible to the router administrator from within the network. A neighbor can only see the existence of your WiFi network (SSID) and signal strength, but they can't see who is connected to it unless they have access to your router.
Does the number of connected devices affect the speed?
Yes, the WiFi channel is shared among all active users. If 10 other devices are connected to your network and they're downloading torrents or watching 4K videos, your internet speed will drop dramatically, and your gaming ping will rise to unacceptable levels.
