In the age of ubiquitous wireless internet, home network security is becoming critical. Users often notice sudden speed drops or intermittent connection interruptions, unaware that someone else might have accessed their router. Unauthorized access — this is not only traffic theft, but also a potential threat to your personal data stored on computers and smartphones.
There are several proven ways to find out how many devices are currently consuming your data. The most reliable methods involve accessing your router's admin panel, but specialized software can be used for a quick check. Understanding How to check the number of WiFi users, will allow you to quickly respond to any anomalies in the network.
In this article, we'll detail the algorithms for different manufacturers' equipment, explore the features of mobile apps, and provide recommendations for setting up filtering. Regardless of whether you're using an older version, TP-Link or a modern mesh system, the principles of customer discovery remain similar.
Analysis via the router's web interface
The most reliable way to get information about connected clients is to look "under the hood" of your router. The web interface provides access to a complete list of devices, their MAC addresses, and the current connection status. To get started, open any browser on a device connected to the network and enter the gateway IP address. This is usually 192.168.0.1 or 192.168.1.1, but the exact address is always indicated on the sticker on the bottom of the router.
After entering your login and password, the control panel will open. Interfaces from different manufacturers may look different, but the logic remains the same. You need to find the section related to the wireless network status or client list. In the menu, this is often labeled as Wireless, Wi-Fi or Status.
⚠️ Attention: Default administrator passwords, such as admin/admin, are the biggest vulnerability. If you've never changed them since purchasing your router, any hacker within range can access the settings and disable your internet connection.
Within the corresponding section, you'll see a table or list displaying all active connections. It's important to pay attention not only to the number, but also to MAC addresses devices. It is the unique identifier of the network card that allows you to distinguish your smartphone from your neighbor's phone. Some modern interfaces, for example, Keenetic or Mikrotik, even allow you to give devices user-friendly names, making monitoring easier.
Navigating the menus of popular router models
Finding the right tab can be confusing if your router's interface isn't translated into Russian or has a complex structure. Manufacturers use different names for the traffic monitoring sections. Let's break down where to find information on the most common router models so you can quickly navigate them.
For devices from TP-Link (especially older versions with an orange-green interface) the information you are looking for is usually found in the menu Wireless -> Wireless StatisticsIn new versions of the interface (blue design), you need to go to the section Basic -> Wireless, where a list of connected clients will be displayed. In routers Asus with firmware Asuswrt you need to click on the network map icon in the center of the main screen or go to Network map -> Clients.
Equipment from D-Link often hides this information in a section Status -> LAN or Wireless -> Station. For provider routers, such as Sagemcom or Sercomm, the path may not be obvious: look for tabs Local Network or Home NetworkIf you are using equipment from Zyxel, go to the section Wi-Fi network and select a subsection Client list.
What should I do if I see an unfamiliar gadget in the list of devices?
If you find a device you don't recognize, don't panic. First, check all your gadgets: smart lamps, TVs, consoles, and vacuum cleaners often have strange names. If, after checking all your smart devices, the MAC address remains, immediately change your WiFi password and enable filtering.
The table below shows sample navigation paths for quick searching:
| Router brand | Menu section | Subsection | Tab name |
|---|---|---|---|
| TP-Link | Wireless | - | Wireless Statistics |
| Asus | Network Map | - | Clients |
| D-Link | Status | - | Wireless Clients |
| Keenetic | Client list | - | Home network |
| Mikrotik | Wireless | - | Registration |
Some router models, especially budget ones, may not display the device name, showing only the MAC address. In this case, you'll have to map the addresses manually. It's also worth keeping in mind that if the device is asleep or in power-saving mode, it may temporarily disappear from the list, even if it's not technically disconnected from the network.
Using specialized PC programs
If accessing your router settings seems too complicated or the interface is blocked by your ISP, you can use third-party computer software. These utilities scan your local network and identify all active IP and MAC addresses. One of the most popular and functional tools is Wireless Network Watcher from NirSoft.
This utility requires no installation and works instantly. Once launched, it automatically detects your network card and begins scanning the address range. The program window displays a list of all devices, their manufacturers (based on MAC address), IP addresses, and last detected time. This allows you to quickly identify who is using your line.
Another powerful alternative is Angry IP ScannerThis open-source tool allows you to scan not only your local network but also specify any IP address range. It's useful for more advanced users who want detailed information, including open ports. However, for a simple user count, simpler software is also suitable.
⚠️ Attention: Download network analysis software only from the developers' official websites. Software versions found on third-party file-sharing services may contain viruses or Trojans, which themselves can leak data.
When using such programs, it's important to understand the difference between active and passive connections. The scanner displays devices that responded to the request. If a computer in a neighboring apartment is configured for stealth mode or has a strict firewall, it may not appear in the list even if it's within range. Therefore, software methods should be considered a supplementary tool.
Mobile applications for network monitoring
Your smartphone is always at hand, so using mobile apps is the most convenient way to quickly check the number of WiFi users. For platforms Android And iOS There are many utilities that provide network visualization directly on your phone screen. One of the leaders in this niche is the app Fing.
Application Fing Scans the network and provides detailed information about each device: type (phone, laptop, camera), manufacturer, MAC address, and even operating system. It can detect new devices and send notifications, making it an excellent security tool. The app WiFi Analyzer, which was originally created to search for free channels, but also has a client viewing module.
For users iPhone It's worth noting that due to iOS limitations, some scanning features may be limited compared to Android. However, basic information about connected devices and their IP addresses can be obtained without any problem. Many router manufacturers, such as Tenda or Xiaomi, are releasing their own apps that allow you not only to view the list, but also to block users with one click.
Scanning via mobile internet (3G/4G/5G) will not yield results, as you'll be connected to a different network. Also, some antivirus programs on your phone may block port scanners, interpreting them as suspicious activity.
How to distinguish your device from someone else's
The most difficult part of monitoring is identification. When you see a list of 10-15 MAC addresses, it's easy to get confused. The first step is to conduct a complete audit of all the gadgets in your home. Smartphones, tablets, laptops, smart TVs, game consoles, smart plugs, lamps, robotic vacuum cleaners, and even some modern refrigerators—they all connect to WiFi.
To simplify the task, you can use the elimination method. Disable WiFi on all your devices one by one and monitor which device disappears from the list in the admin panel. Write down the MAC addresses of known devices and assign them descriptive names in the router settings (function Static DHCP (or renaming clients). This will take time, but will save you a lot of hassle in the future.
Pay attention to the network card manufacturer. The first 6 characters of the MAC address (OUI) indicate the brand of the device. For example, if you see an address starting with 00:1A:2B, and it matches your laptop Lenovo, then this is your device. If a device of an unknown brand or with a name like Android-xyz, which you cannot identify, is a cause for concern.

Methods of protection and blocking of outsiders
If you detect an uninvited guest, you need to act quickly. The simplest, but least effective, method is to hide the network name (SSID). This will prevent the device from connecting automatically, but an experienced user can easily find the hidden network manually. A much more effective approach is to change the WiFi password and select a strong encryption type, such as WPA2-PSK or WPA3.
The safest way is to use MAC filteringThis feature allows you to create a "whitelist" of devices that are allowed to connect. All others, even with the password, will be blocked from accessing the network. The downside of this method is that every time you buy a new device, you'll have to manually enter its MAC address into the router settings, which can be inconvenient for large families.
It is also recommended to disable the function WPS (Wi-Fi Protected Setup). Despite the convenience of push-button connection, this protocol has vulnerabilities that allow attackers to brute-force the PIN code and gain access to the network in a matter of hours. In modern routers, WPS is often disabled by default, but on older models, it's best to manually disable it in the wireless settings.
⚠️ Attention: After changing your password, all your devices will be disconnected from the network. You'll have to re-enter the new access key on each smartphone, tablet, and TV. Prepare the new password in advance to avoid being stuck without internet access on half your devices.
Frequently Asked Questions (FAQ)
Can my neighbor steal my WiFi if I changed the password?
If you've changed your password to a complex one (more than 10 characters, including numbers and special characters) and use WPA2/WPA3 encryption, it's virtually impossible to hack your network by brute-forcing the password. However, if you have WPS enabled, the theoretical vulnerability remains. The password may also have been saved on the devices of previous guests; changing the password will disable their access.
Does the number of connected devices affect internet speed?
Yes, the channel's bandwidth is shared among all active users. If one of the connected devices (yours or someone else's) starts downloading a large file or watching a 4K video, the speed on other devices will drop significantly. The router also has a limit on the number of simultaneous connections; if this limit is exceeded, new devices may not connect, and older devices may lose connection.
How can I find out who is online if their device name is hidden?
The device name can often be changed in the device's settings or temporarily assigned in the router. If the name is hidden, use the MAC address and network card manufacturer as a reference. You can also monitor the network activity indicator on the router: if you turn off all your devices and the data transfer indicator (WAN/LAN) is blinking, it means someone else is using your traffic.
Are WiFi scanner apps safe to use?
Apps from reputable developers (Fing, WiFi Analyzer) are safe. They use standard system calls to obtain network information. However, avoid dubious programs that promise to "hack your neighbor's WiFi"—such software often contains malicious code. Always check the permissions an app requests during installation.
What should I do if I can't access my router settings?
Make sure you're connected to this router's network (via cable or WiFi). Check that the IP address is correct (by default, it's often 192.168.0.1 or 1.1). If you've forgotten the password, you'll need to reset the router using the reset button on the router itself, which will restore it to the factory settings listed on the sticker.
