In the digital age, the home network is becoming the center of our digital lives, connecting smartphones, laptops, smart TVs, and video surveillance systems. From time to time, it becomes necessary to know exactly which devices are currently using your internet connection. This may be necessary for diagnosing speed issues, detecting unauthorized access, or simply monitoring your children.
There are several proven ways to obtain complete information about local network clients. You can use your router's built-in web interface, specialized mobile apps, or the operating system's command line. The method you choose depends on your equipment model and your level of technical expertise.
In this article, we will examine in detail the action algorithms for routers from various manufacturers, such as Keenetic, TP-Link And AsusYou'll learn not only how to view your connection list but also how to restrict access to uninvited guests, ensuring the stable operation of your internet.
Checking via the router's web interface
The most reliable and informative way to obtain network information is to access the router's control panel through a browser. To do this, you need to know the gateway IP address, which is usually set to 192.168.0.1 or 192.168.1.1Enter this address into the address bar of any browser on a device connected to the network.
After entering your login and password, the main menu will open. The interface may vary, but the basics remain the same: find the section responsible for network status. It's usually called Wireless Status, Client list or DHCP Client ListThis displays a complete picture of network activity.
⚠️ Warning: If the default password for the router's admin panel hasn't been changed since purchase, hackers can easily access the settings. Immediately change the default password to a strong and unique one.
Inside the section you will see a table where each device is assigned a unique IP address And MAC addressThis data allows you to identify gadgets, even if their names (Hostname) are not displayed correctly. For example, you might see a device named Unknown, but by the MAC address you can determine its manufacturer.
Using the manufacturer's mobile applications
Modern network equipment manufacturers understand that managing a browser from a phone is inconvenient. Therefore, companies TP-Link, Asus, Keenetic And Mikrotik We've developed our own apps for iOS and Android. These programs allow you to monitor your network literally "on the go."
After installing the app and completing the initial setup (usually requiring linking a manufacturer account), you gain access to the dashboard. The main screen often displays a schematic representation of the network, showing the number of active clients. Clicking on the icon displays a detailed list.
- 📱 KeeneticThe My.Keenetic app allows you to not only view the list, but also rename devices for convenience and block them with one click.
- 📱 TP-Link: The Tether or Deco app shows the connection status of each client and how long it has been active on the network.
- 📱 Asus: The "ASUS Router" application has a "Client Status" function, which displays the data exchange speed for each gadget.
The main advantage of mobile utilities is the ability to react instantly. If you spot an unfamiliar device, you can block its access with a single tap, without having to delve into the web interface's settings. This is especially useful for protecting your home network from neighbors.
Analyzing the list of devices in the interface
Once you've accessed the list of connected clients, it's important to be able to correctly interpret the information displayed. Device names are often confusing, for example, android-df45a2 or DESKTOP-892To understand what kind of gadget this is, you need to pay attention to additional parameters.
The key identifier is MAC address (Media Access Control). This is a unique physical address of a network card, consisting of 12 hexadecimal digits. The first six characters of this address (OUI) identify the device manufacturer. Knowing this code, you can accurately determine whose phone or laptop it is.
Example MAC address: 00:1A:2B:3C:4D:5E
Where 00:1A:2B is the manufacturer code
It is also worth paying attention to the connection type: Wireless (wireless) or LAN (cable). This will help you determine whether the device is physically connected to the router or is located somewhere within Wi-Fi range. If you see a wireless device with a high data transfer rate, this is cause for concern.
What is the IP address on this list?
An IP address (e.g., 192.168.1.45) is a temporary digital identifier assigned by a router to a device for data exchange. It can change each time a connection is reconnected unless it is statically reserved.
Table of manufacturer identification by MAC addresses
To quickly check the device's identity, you can use the manufacturer code table. Below are the most common prefixes you might encounter in your router's client list.
| MAC Prefix (OUI) | Manufacturer | Typical devices |
|---|---|---|
| A4:50:46 | Apple, Inc. | iPhone, iPad, MacBook |
| 00:1E:58 | Samsung Electronics | Smartphones, TVs, tablets |
| 3C:5A:B4 | Google, Inc. | Android smartphones, Chromecast |
| 00:50:C2 | TP-Link Technologies | Routers, adapters, cameras |
| B8:27:EB | Raspberry Pi Foundation | Single-board computers, smart home |
Using this data, you can match an obscure name in the list to a real device. For example, if you don't have the equipment Samsung, and a device with the corresponding prefix is listed, it’s worth checking whether the neighbors have connected.
Checking via the Windows and macOS command line
If access to the web interface is blocked or you prefer operating system tools, you can use the command line. This method allows you to see the devices your computer has directly communicated with or retrieve a list from the ARP table.
In the operating system Windows open command prompt by typing cmd in search. To display the ARP table, which contains the IP and MAC addresses of devices on the local network, use the command arp -aHowever, this list may be incomplete, as it only contains those with whom contact has been made.
A more advanced method is to use a network scanning utility. On macOS, you can use Terminal and the command nmap (if Homebrew is installed) or built-in arp-scanThis allows for a more complete picture of connections within a network segment.
Windows command: arp -a
Scan command (Linux/Mac): nmap -sn 192.168.1.0/24
This method is more suitable for advanced users who understand how network protocols work. For a quick check for rogue users, it's easier to use the router's web interface.
Network protection and user blocking
If you detect a rogue device, you need to take immediate action. The easiest way is to change your Wi-Fi password. After doing this, all devices will be disconnected, and you'll have to reconnect them using the new security key.
A more flexible method is to use MAC filteringYou can create a "Blacklist" in your router settings by adding the MAC address of the intruder. The router will then ignore connection requests from that specific device, even if it knows the correct password.
- 🔒 Change password: A radical but effective method. Set a complex password using mixed-case letters and numbers.
- 🔒 MAC filtering: allows you to block a specific device while leaving access to others.
- 🔒 Disabling WPS: This feature is often a security hole through which attackers can guess the password.
⚠️ Warning: MAC addresses can be spoofed (cloned). If a technically savvy attacker is able to copy the MAC address of your authorized laptop, MAC filtering is an additional, but not absolute, measure of protection.
It is also recommended to disable the function WPS (Wi-Fi Protected Setup), as it allows connecting to the network by simply pressing a button or guessing a PIN code, which is a vulnerability. In modern routers, this feature is often disabled by default or hidden.

Frequently Asked Questions (FAQ)
Why are there unknown names displayed in the device list?
Operating systems or IoT devices (light bulbs, sockets) often don't transmit a user-friendly hostname, but use a standard model designation or simply a set of characters. Use the MAC address for identification.
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 access point (SSID) and signal strength, but not the makeup of your network unless they have access to your router.
How often should connected devices be checked?
It's recommended to run a test once a month or whenever you notice a sudden drop in internet speed. Regular monitoring helps quickly identify problems.
What should I do if I can't access my router settings?
Try the default login and password combinations (usually admin/admin), which are listed on the sticker on the bottom of the device. If the password has been changed and forgotten, you'll need to perform a reset using the button on the device.
