How to view the number of users connected to a WiFi router

In the age of total digitalization, the home network is becoming the center of digital life, where every gadget requires a stable connection. A sudden drop in internet speed or unstable video calls often indicate that unauthorized users have connected to your network. Controlling the connection list — this is the first and most important step in ensuring the security of your personal data and maintaining the speed of your network access.

Many users are unaware that their neighbors or passersby may be using their connection to download heavy content, which can overload their equipment. RouterA network operating at its limits due to excessive clients begins to overheat and lose data packets. In this article, we'll take a detailed look at how to identify uninvited guests and regain full control of your network space.

Direct signs of an unauthorized connection to the network

Before messing with your equipment settings, it's worth paying attention to indirect but very telling symptoms. If your internet connection suddenly slows down, even though your provider hasn't reported any outages, this is cause for concern. This is especially noticeable in the evening, when the provider's network is usually under heavy load, but a drop in speed to dial-up modem levels is no longer normal.

Another warning sign is the strange behavior of the indicators on the router body. The light WLAN or WiFi may flash frequently and randomly even when you have turned off all your devices or left the house. Wireless module activity In the absence of legitimate users, this is a virtually 100% guarantee that someone is actively downloading files or watching videos through your access point.

It's also worth paying attention to the behavior of smart devices in the home. Light bulbs may stop responding to commands from your phone, and security cameras may lose connection. This happens because DHCP server The router has exhausted its pool of allocated IP addresses, handing them over to other devices. In this situation, your new devices simply cannot obtain an address and connect to the network.

⚠️ Attention: Don't confuse phantom connections with system processes. Modern Smart TVs, game consoles, and even some home appliances can generate background traffic for updates. However, if you see a phone with an unfamiliar model name in the device list, this is a reason for immediate action.

For initial diagnostics, you can use dedicated mobile apps from router manufacturers or third-party network scanning utilities. These will display a list of active hosts on the local network without the need to log in to the web interface. However, to get a complete picture and manage access, you will still need to log in to the admin panel.

Information about connection methods and interfaces may vary depending on the firmware version of your device. Manufacturers regularly update their software, changing the layout of menu items. Always consult the official documentation for your specific model if the default paths differ.

Login to the router control panel: standard addresses

To access the client list, you need to log in to the device's web interface. To do this, you'll need any device already connected to the network (a computer, laptop, or smartphone). Open any browser and enter your gateway's IP address in the address bar. Most often, this is 192.168.0.1 or 192.168.1.1, but there may be other options depending on the manufacturer.

If the default addresses don't work, you can find the correct gateway IP address through the operating system command line. On Windows, click Win + R, enter cmd and press Enter. In the window that opens, enter the command ipconfig and find the line "Default Gateway." This is the address you need to enter into your browser.

ipconfig

After entering the address, the system will ask for a login and password. By default, most devices use the following combinations: admin/admin or admin/passwordThis information may also be found on a sticker on the bottom of the router. Network security This directly depends on whether you changed this data during the first setup, since attackers often use standard passwords to log in.

In some cases, the browser may display a warning that the connection is not secure. This is normal for local addresses, as a security certificate cannot be issued for an internal IP. You must accept the risk and continue to the page to proceed with the setup.

Searching for a list of clients on routers of different brands

Interfaces vary widely between manufacturers, making it difficult to find the information you need. We've compiled the main navigation paths for the most popular brands to help you navigate the menus more quickly. Look for sections related to wireless networking, status, or connected devices.

• 📡 TP-Link: In the new interface (green/blue), go to "Basic" -> "Wireless" -> "Wireless Statistics." In the classic orange interface, this is often found under "Wireless" -> "Wireless Statistics."
• 🌐 Keenetic: In the bottom menu bar, select the "My Networks & WiFi" icon, then go to the "Client List" tab. This displays the most detailed information, including the device name and connection type.
• 🌀 ASUS: The main page of the web interface (Network Map) usually displays the network map. To the right or center, there will be a "Clients" section where you can see all connected devices. Alternatively, you can go to "Advanced Settings" -> "Wireless Network" -> "Client List."
• 📶 D-Link: Go to "Advanced Settings," then "Status" -> "Clients" or "DHCP Client List." On some models, this information is available directly on the main page in the "Network Map" widget.

Within these sections, you will see a table containing MAC addresses, IP addresses, and sometimes device names. MAC address — is a unique network interface identifier that helps accurately identify a device, even if it hides its name. Compare the list with your existing gadgets: phones, laptops, TVs, and smart devices.

If you see a device you can't identify, try temporarily disconnecting your devices from WiFi one by one and observing the changes in the list. This will help you figure out which device is hiding behind an unknown name or MAC address. Some devices may appear as "Unknown" or simply a string of numbers.

Analyzing the table of connected devices

The resulting list may seem confusing to the untrained user, but several parameters play a key role. The table typically displays the hostname, IP address, MAC address, and connection type (wired or wireless). It's the connection type that matters. Wireless or WiFi Indicates that the device is connected over the air.

Pay attention to the IP address lease time. If the device is actively transmitting data, this timer will update. Static devices, such as printers or smart plugs, may have a permanent lease, while guest phones will appear and disappear from the list.

Some modern routers automatically detect the device type and display the appropriate icon (TV, phone, computer). This greatly simplifies identification. However, if the device is connected for the first time or has specific privacy settings, it may appear as an "Unknown Device."

⚠️ Attention: Attackers can use MAC address cloning or randomization techniques (especially on iOS and Android) to conceal their identity. If the number of connected devices increases but the list remains visibly unchanged, someone may be masquerading as a legitimate device.

What is MAC filtering?

This security method requires the router to only allow devices with pre-approved MAC addresses onto the network. Even with the WiFi password, an intruder with an unauthorized address will be unable to connect. However, this method is labor-intensive to maintain, as manual changes to the router settings are required for each new guest.

Methods for blocking unwanted users

Once you've identified the intruder, you need to immediately restrict their access. The simplest and most effective way is to change the password for your wireless network. Changing the password will disable all devices, and you'll only have to reconnect your own devices using the new security key.

A more flexible method is to use Blacklist (blacklist) or MAC address filtering. In the router interface, next to the name of an unknown device, there's usually a "Block" button or a hand icon. Clicking this will blacklist the intruder's MAC address, causing the router to ignore its connection requests.

There's also a "Whitelist" mode, which is the opposite of "Blacklist." In this mode, the router allows connections ONLY to devices on the approved list. All others, even with the password, will be blocked. This is the highest level of security, but it requires manual configuration for each new guest.

Remember that after blocking or changing the password, it is recommended to reboot the router. This will clear the DHCP cache and ARP table, ensuring that the blocked devices have truly lost connection and are not using old addresses.

Security setup and protection against replay attacks

To prevent this from happening again, you need to strengthen the security of your access point. First, check the encryption type. Make sure the "Secure" mode is selected in the wireless network settings. WPA2-PSK or WPA3Old protocols WEP And WPA They can be hacked in a few minutes even by beginners using simple programs.

Be sure to disable the feature WPS (Wi-Fi Protected Setup). This technology is designed to simplify device connections with the push of a button, but it contains vulnerabilities that allow PIN code recovery and network access without knowing the password. This feature is often disabled by default in modern routers, but it's worth checking.

Update your router firmware regularly. Manufacturers release updates not only to add new features but also to patch security holes. Older versions of the software may contain known vulnerabilities that could allow attackers to access the admin panel.

• 🔒 Use complex passwords: at least 12 characters, uppercase and lowercase letters, numbers, and special characters.
• 📡 Hide the network name (SSID): Enable the "Hide SSID" option to prevent the router from broadcasting the network name. You'll have to connect manually by entering the name and password.
• 🚫 Disable remote management: Make sure that the router's web interface can only be accessed from the local area network (LAN), not from the internet (WAN).

A comprehensive approach to security ensures that your internet connection is used exclusively by you and your family. Regular monitoring of connected devices should become a habit, especially if you live in a densely populated apartment building.

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

If you have a strong password (WPA2/WPA3) and disabled WPS, it's technically almost impossible to brute-force the password. However, if the password was written down on a piece of paper that others saw, or you shared it with guests who might pass it on, they will retain access until the next key change.

Does the number of connected devices affect internet speed?

Yes, it does have a direct impact. The connection bandwidth is shared among all active users. If one connected device starts downloading large files or watching 4K video, the others will only get a small portion of the bandwidth, leading to lag and buffering.

What should I do if I see "Unknown device" in the list of devices?

First, try disabling WiFi on all your devices one by one. If the unknown device's name changes or disappears, you've identified the intruder. If the device remains in the list even when all your other devices are turned off, it's an intruder and should be blocked.

Is it safe to use router management apps?

Official apps from manufacturers (TP-Link Tether, Keenetic, Mi Wi-Fi) are secure and convenient. They use the same authorization protocols as the web interface. However, avoid third-party apps from unknown developers that require access to your local network.
