How to find out how many devices are connected to a Wi-Fi router

A slow internet connection or intermittent disconnects are often the first signs that an uninvited guest has entered your home network. When you pay for a high-bandwidth plan, but videos load in low resolution and pages load slowly, it's natural to suspect unauthorized access. Control of connected devices — This is a basic home network administration skill that allows you to not only identify "neighboring" users but also understand which gadgets are consuming traffic.

Modern routers have powerful monitoring tools that allow you to see all active connections in real time. However, the settings interfaces vary across different manufacturers, such as TP-Link, Asus, Keenetic or Mikrotik, can vary significantly in structure and menu layout. In this article, we'll cover universal verification methods that will help you quickly get a complete picture of what's going on in your local network.

In addition to identifying strangers, knowing the exact number of connected devices is necessary for proper configuration. QoS (traffic prioritization) and parental controls. If you don't know how many devices are simultaneously using the channel, you won't be able to properly allocate your router's resources. Let's look at a step-by-step algorithm that applies to most modern equipment models.

⚠️ Note: Router web control panel interfaces are regularly updated by manufacturers. The layout of menu items may differ from that described in the instructions depending on your device's firmware version.

Login to the router control panel

The first and mandatory step to obtaining any network information is logging into the router's administrative panel. This can be done either from a computer connected via cable or from a smartphone on the same Wi-Fi network. You need to open any browser and enter the default gateway IP address in the address bar. Most often, this is 192.168.0.1 or 192.168.1.1, however, some manufacturers, for example Asus or Keenetic, allow you to use domain names like router.asus.com.

After navigating to the address, the system will ask for your login and password. If you've never changed these details, they're likely located on a sticker on the bottom of the device. The default combinations are often admin/admin or admin/password. Network security directly depends on the complexity of this password, so it is highly recommended to change the factory credentials immediately after the first setup.

What to do if the default IP doesn't work?

If addresses 192.168.0.1 and 192.168.1.1 don't open, check your network card settings. In the Windows command prompt, enter "ipconfig" and find the line labeled "Default gateway"—this is your router's address.

In some cases, access to the control panel may be blocked by antivirus software or firewall settings. Make sure your computer is on the same subnet as your router. If you're connected via a VPN, you should temporarily disable it, as it routes traffic through remote servers, making the router's local address unavailable for direct connection.

Finding a list of clients in the router interface

After successful authorization, you'll see the dashboard (main panel) or settings menu. The information you're looking for is usually hidden in sections with names containing the words "Status," "Network Map," "Clients," or "Wireless." On routers TP-Link with the new firmware you need to go to the section Basic (Basic settings) and select the tab Wireless (Wireless Mode) where a list of all active hosts is displayed.

For equipment users Asus Pay attention to the main "Network Map" page. On the right side of the screen, you'll usually see a "Client" section, where a number indicates the total number of connections. Clicking this number or the corresponding icon will display a detailed list with device names, their MAC addresses, and the connection type (2.4 GHz or 5 GHz).

In devices from Keenetic (formerly ZyXEL), the most informative section is the "Client List" section, often located in the sidebar or accessible via a widget on the main screen. It displays not only the connection status but also the data transfer rate for each device in real time, allowing you to instantly identify bandwidth hogs.

Using mobile apps for monitoring

Modern network equipment manufacturers are emphasizing mobility by offering convenient smartphone apps. This allows you to check who is connected to your Wi-Fi network without having to find a computer or cable. Apps from Tenda, Mercusys or TP-Link Tether provide a visualization of the network in the form of a graphical map, where each connected gadget is represented by an icon.

The main advantage of mobile utilities is the ability to instantly block unwanted users. If you detect a device (for example, one with the name "Unknown device" or a suspicious MAC address), you can disconnect it with one tap and add it to your list. blacklistThis action is often more effective than simply changing your password, as it doesn't require reconnecting all your trusted devices.

However, it's worth keeping in mind that the apps' functionality may be limited compared to the full web version. For example, detailed traffic statistics or fine-tuning MAC address filtering may only be available through a browser. Nevertheless, for quick diagnostics and basic monitoring, the mobile version is an excellent solution.

Specialized programs for network scanning

If the router's web activity seems too complex or you want a more in-depth technical analysis, third-party network scanning utilities can help. Programs like Wireless Network Watcher, Fing or Advanced IP Scanner They can reveal much more detail than standard router tools. They scan the entire address range and provide information about the network card manufacturer, operating system, and open ports.

One of the most popular programs for Windows is Wireless Network Watcher from NirSoft. It requires no installation, works instantly, and displays a list of all devices in a table. The program can highlight new devices that have appeared on the network since the last scan, which is extremely convenient for monitoring connection dynamics.

For macOS and Linux users, a great alternative is the utility nmap, although it requires working with the command line and certain knowledge. The command nmap -sn 192.168.1.0/24 (replace the address with your subnet) will perform a ping scan and show all active hosts. For those who prefer a graphical interface, there is a version Zenmap.

MAC address analysis and device identification

The most difficult part of monitoring is figuring out which device each address in the list belongs to. Host names are often uninformative, such as "android-12345" or "desktop-abc." The key is MAC address — a unique identifier of the network interface, consisting of 12 hexadecimal digits.

The first six characters of the MAC address (OUI) identify the device's manufacturer. Knowing this code, you can easily determine whether the device is a phone. Samsung, laptop Dell or a smart light bulb XiaomiThere are online OUI databases where you can enter the first three bytes of an address to get the exact vendor name.

It's recommended to make a list of the MAC addresses of all your trusted devices in advance. You can do this by looking at the "About Phone" or "Status" settings on each device. By recording this information in a notebook, you'll be able to instantly distinguish your devices from others in the future by simply checking the last digits of the addresses.

⚠️ Note: Modern operating systems (iOS 14+, Android 10+) use the "Private Wi-Fi Address" (Randomized MAC) feature by default. This means that a device can change its MAC address each time it connects to a network, making it difficult to identify using a static list.

Methods of protection and access restriction

Once you've identified an unwanted device, you need to immediately block its access. The easiest way is to change the Wi-Fi network password. This will forcibly disconnect all users, and you'll have to re-enter the new key on all your devices. While this is effective, it's time-consuming and can be inconvenient if you have a lot of smart devices in your home.

A more flexible method is MAC address filteringYou can enable the "Allow List" mode in your router settings, which only includes your devices. Any other device, even with the password, will be unable to connect to the network. This is the most secure, but also the most labor-intensive method, as adding new guest gadgets requires manual router configuration.

It is also worth checking if the function is enabled WPS (Wi-Fi Protected Setup). This technology allows you to connect to a network by simply pressing a button or entering a PIN, but it is considered vulnerable. Attackers can brute-force the WPS PIN and gain access to your network even without knowing the master password. Disabling WPS in your router settings will significantly increase security.

Common problems and their solutions

Sometimes users encounter a situation where devices appear in the list with the status "Inactive" or "Static IP," even though the device has been physically turned off for a long time. This is because the router caches IP address lease information (DHCP Lease). To clear the list, you can try rebooting the router or find the "Clear Client List" / "Rebuild DHCP Table" option in the settings.

Another common problem is the inability to identify a device because it doesn't broadcast its hostname. In such cases, the only option is to rely on the MAC address. If you see the device but can't figure out what it is, try disabling Wi-Fi on your devices one by one and watch for the entry in the router's client list to disappear.

If your router shows fewer connected devices than it actually has, the DHCP pool limit may have been exceeded. You can expand the range of addresses issued in your LAN settings, for example, from 192.168.1.100 to 192.168.1.200This will allow you to connect more gadgets simultaneously without addressing conflicts.

Why doesn't the router see 5 GHz devices?

Some older router models or settings may have separate client lists for 2.4 GHz and 5 GHz frequencies. Check to see if the connection list for one of the frequencies is hidden in the advanced wireless settings.

Questions and Answers (FAQ)

Can my neighbor steal my internet if I changed my password?

If your neighbor was already connected to your network before changing the password, their device will automatically reconnect because the password is saved in their device's memory. To kick them out, you'll need to not only change the password but also forcefully disconnect through the client list or reboot the router immediately after changing the access key.

Does the number of connected devices affect internet speed?

Yes, it does. The Wi-Fi channel is shared among all active users. If one connected device starts downloading large files or watching 4K video, the available speed for other devices (such as a browser or messaging apps) can drop significantly due to lack of bandwidth.

What is the "Unknown" device in the client list?

The "Unknown" status usually means that the device isn't broadcasting its hostname when connecting or that the router can't recognize it. This could be your smart kettle or security camera, or someone else's gadget. Be sure to check the MAC address for identification.

How often should I check the list of connected devices?

It's recommended to perform a preventative check once a month or whenever you notice an unexplained drop in internet speed. Regular monitoring helps detect network compromises early and prevent your connection from being used for illegal activities.
