How to view a list of devices connected to Rostelecom's WiFi

In the modern digital home, where smartphones, smart TVs, tablets, and laptops are all connected to the wireless network, traffic management is critical. Slow internet speeds, slow loading pages, and interrupted video calls often indicate that your connection is overloaded. Illegal connection Unauthorized access by third-party users is one of the most common causes of such problems, especially if the password was once shared with guests or written down in plain text.

Rostelecom provides subscribers with equipment from various manufacturers, and management interfaces can vary significantly. However, the basic principle of monitoring network activity is the same for all models: access to the router's administrative panel. This is where the ARP table and the list of active DHCP clients are stored, allowing you to see the actual IP addresses and MAC addresses of all devices currently on the air.

In this article, we'll detail the steps to identify hidden connections, learn how to distinguish system devices from guest devices, and consider methods for blocking unwanted users. You'll learn which technical parameters You need to check to avoid accidentally blocking your smart speaker or printer, and how to set up security so that the question "how to view a list of devices" never arises again.

Initial diagnostics of speed and signs of hacking

Before delving into complex router settings, it's worth running a basic diagnostic, which often provides 90% of the answer to the question of whether there are unauthorized connections. If your internet speed drops at certain times of day or suddenly decreases immediately after you get home, this could be an indirect sign that someone is actively downloading files or watching 4K videos using your infrastructure.

Pay attention to the indicators on the router itself. On many models of equipment RT-AX or Sercomm, which are often found with your ISP, have a WiFi activity indicator (usually a blinking antenna or WLAN icon). If you've turned off all your wireless devices and the light continues to blink rapidly and rhythmically, it means there's active data transfer with someone else.

⚠️ Attention: Don't confuse background operating system updates with active downloads. Smartphones and consoles can update in the background, creating bandwidth load even without your intervention.

For a more accurate picture, you can use specialized smartphone apps like Fing or Network Scanner. They will display a list of devices on the local network without having to access the router's web interface. This is a quick way to understand how many nodes your phone is currently seeing and compare this figure with the actual number of devices you own.

Login to the Rostelecom router's web interface

To obtain detailed network information, you need to log in to your router's control panel. The standard login address for most models provided by your provider is 192.168.1.1 or 192.168.0.1Enter this address into the address bar of any browser while on the same network you want to check.

The system will ask for your login and password. On new devices, this information is often found on a sticker on the bottom of the case (fields Username And Password). If you have previously changed the login details for the router settings and have forgotten them, you will have to perform a factory reset using the button Reset, which will temporarily interrupt your internet connection.

In case of using a branded router RT-KEENETIC or Sagemcom With the "My Rostelecom" app installed, you can log in via your cloud account. This is even more convenient, as it allows you to manage your network remotely, without having to be at home. However, for a more in-depth analysis of connected clients, a classic web search using a local IP address often provides more technical information.

Analyzing the client list depending on the router model

The admin panel interface varies greatly depending on the hardware manufacturer. Rostelecom has a diverse equipment portfolio, so menu navigation may vary. Below are the paths for the most popular models to help you quickly find the section you need.

On devices Sagemcom (often found in old tariffs) look for the tab Local Network or LAN, and then subsection DHCP Clients or Connected DevicesThis displays a table where each IP address is associated with a MAC address and, sometimes, a hostname. Hostnames may be unreadable (for example, android-df34a), so it’s better to focus on MAC addresses.

In routers Eltex And Sercomm (new models with 5 GHz support) the path often lies through the menu Wi-Fi -> Station Info or Associated StationsThis section displays not only the IP address but also the signal strength (RSSI) of each connected device, which helps determine where the intruder is physically located—near the router or with the neighbors behind the wall.

If you are using generic firmware or your own hardware, look for sections with the words Wireless Status, Hosts List or Active UsersIn some interfaces, information is divided into two tabs: wired clients (LAN) and wireless (WLAN). It's important to check both, as an attacker could theoretically gain access via a cable if they have physical access to the apartment, although WiFi is a more likely attack vector.

What should I do if I see an unknown device named "Unknown" in the list?

Operating systems often don't transmit their hostname correctly. A device may be listed as "Unknown" but actually be your own IoT gadget (smart light bulb, power outlet). Check the MAC address against the sticker on the device or temporarily unplug the gadget—if it disappears from the list, it's the one.

Identifying devices by MAC address

The most reliable way to distinguish your phone from your neighbor's is by analyzing the MAC address. This is a unique identifier for a network interface, consisting of 12 hexadecimal characters (e.g., A4:5E:60:C2:11:09). The first 6 characters (OUI) indicate the device manufacturer, making the search much easier.

There are many online services for decoding MAC addresses. By entering the first six characters of a suspicious address into an OUI search engine, you can identify the brand. If you see a device from Apple, and you don’t have equipment of this brand, or a device from XiaomiIf you haven't bought anything Chinese, this is a reason to be wary.

However, it's worth keeping in mind a nuance of modern iOS and Android operating systems. The "Private Wi-Fi Address" feature generates a random MAC address for each network to protect privacy. This means your iPhone may appear in the router's list with one address one day and a completely different one the next, appearing as a new, unknown device.

⚠️ Attention: In modern versions of iOS (14+) and Android (10+), MAC address randomization is enabled by default. Don't rush to block a device just because its address has changed or doesn't match the one you previously recorded.

For accurate identification, it's recommended to create an inventory of your devices. Write down the MAC addresses of all your gadgets in a notebook or spreadsheet. This will take 10 minutes, but will save you hours of frustration in the future. You can find your MAC address in your phone's settings: Settings -> About phone -> Status (the path may vary slightly depending on the model).

Blocking unwanted users and MAC filtering

If you detect a foreign device, you should disconnect it immediately. In the router interface, there's often a button next to the client's name. Block, Deny or a trash can icon. Clicking this button adds the offender's MAC address to the blacklist, and the router stops assigning an IP address and passing traffic.

A more reliable method is to turn it on MAC filtering Whitelist mode. In this mode, the router allows connections ONLY to devices whose addresses are added to the allowed list. All others, even those with the Wi-Fi password, will be physically unable to connect.

Configuring the whitelist requires caution. If you enable this feature but forget to add the MAC address of your current device (the one you're configuring the router from), you'll lose access to the admin panel. Therefore, first whitelist all trusted devices and only then activate the filter.

After blocking, it's recommended to change your wireless network password. Even if you've blocked a specific "neighbor," the password could have leaked to other sources. Changing the encryption key (WPA2/WPA3) will force all your devices to reconnect, which is a good check: if any don't reconnect, they were the wrong ones.

Preventing and enhancing network security

To prevent a repeat of the "paralyst" (as people call those who steal WiFi), it is necessary to follow basic rules of digital hygiene. First and foremost, avoid using WEP encryption or an open network. Use only WPA2-PSK or modern WPA3, if your hardware supports it.

The password should be complex: do not use dates of birth, phone numbers or simple sequences like 12345678The optimal length is at least 12 characters, including uppercase and lowercase letters and numbers. Such a password is virtually impossible to brute-force within a reasonable time.

You should also disable WPS (Wi-Fi Protected Setup). This technology allows you to connect to the network by pressing a button or using a PIN code, but it has critical vulnerabilities that allow attackers to easily recover the network password. In the router settings, find the section WPS and set the value Disable.

Update your router firmware regularly. Manufacturers, including Rostelecom partners, periodically release updates that patch security holes. If your router is old and hasn't received updates for many years, consider upgrading to a modern model that will not only ensure speed but also protect your data.

Can my neighbor see my personal data if he connects to WiFi?

If the connection is unsecured (open WiFi) or an older encryption protocol is used, traffic interception (sniffing) is theoretically possible. However, with WPA2/WPA3, the neighbor will only see the connection but won't be able to easily decrypt instant messaging messages or banking passwords, as they are transmitted over secure channels (HTTPS). Nevertheless, the risk remains, and the intruder should be blocked.

Why are there more connections than gadgets in the list of devices?

Modern devices often have multiple network interfaces. For example, a smart TV may have a separate MAC address for Ethernet and a separate one for WiFi. Furthermore, virtual adapters, VPN tunnels, or hotspot functions on phones can create additional entries in the DHCP table.

What should I do if I blocked my router by enabling the MAC filter?

If you've lost access to your router after enabling the filter, your only option is to reset it to factory settings. Find the hole on the router's housing. ResetPress it with a paperclip for 10-15 seconds until the router's lights flash. After that, it will reset the factory password (indicated on the sticker) and disable all filters.

Does the number of connected devices affect the speed?

Yes, directly. The bandwidth is shared among all active users. If one neighbor starts downloading torrents, your gaming ping will increase, and video will start buffering, even if you have a 500 Mbps plan, since the router's processor and airtime are limited.

How often should I change my WiFi password?

We recommend changing your password every 3-6 months, or immediately if you suspect a leak (for example, if you shared your password with guests, repairmen, or neighbors). Regularly changing your access key is the best way to prevent unauthorized use of your network.
