Network Monitoring: How to Check Devices Connected to a Keenetic WiFi Router

A modern home network rarely consists of a single smartphone or laptop. Smart TVs, gaming consoles, video surveillance systems, and dozens of gadgets create a complex ecosystem that requires constant monitoring. If your internet starts to slow down or you notice suspicious activity, your first step should be checking the client list in your router. This is a basic administration skill that allows you to instantly assess bandwidth usage and identify unwanted users.

Keenetic routers (formerly Zyxel Keenetic) are renowned for their sophisticated KeeneticOS operating system, which provides transparent network management tools. Unlike many budget routers, you get detailed information about every connection in real time. Web interface Devices display not only IP addresses, but also data transfer speed, connection type, and even the device name, if it's being transmitted correctly. Understanding who's using your WiFi helps you quickly diagnose speed issues or detect if your neighbors are using your bandwidth.

In this article, we'll take a detailed look at how to access the control panel and interpret the data it receives. We'll cover both classic browser access and the use of a mobile app that allows remote network monitoring. Understanding these mechanisms is key. security your local network.

Login to the Keenetic router web configurator

To begin any diagnostics, you need to log in to the device's administrative panel. The standard address for Keenetic routers usually looks like this: 192.168.1.1 or domain name my.keenetic.netEnter this address in the address bar of any browser on a device connected to the router's network. If you previously changed the default access settings, use your username and password; the default pairing is often admin/admin if you didn't set up protection during initial setup.

After successfully logging in, you'll see the main page with status indicators. It's important to pay attention to the section "My Networks and WiFi"**, which is often moved to the start screen in newer firmware versions, displays a summary of all active interfaces. If you're using an older interface, look for the "Client List" or "Home Network" tab in the sidebar. Access to this data requires administrator privileges, so guest access may be restricted.

⚠️ Important: If you can't access the interface using the default address, your router's IP address or local network range may have changed. In this case, check your computer's TCP/IP settings or reset your device to factory settings.

The KeeneticOS interface is adaptive and may look different depending on the firmware version (NDMS v2 or v3). However, the logic remains the same: all active connections are aggregated into a single list. For a more in-depth analysis, go to the "Client List" section via the "My Networks and WiFi" → "Home Network" menu. This displays all devices the router considers authorized and currently active.

Analyzing the list of connected clients

After navigating to the appropriate section, a table will open with a list of all devices. Each list item contains critical information: MAC address, IP address, hostname (if available), and connection type (Ethernet or WiFi). MAC address is a unique identifier for a network card and serves as the primary reference point when searching for unknown devices. Hostnames can be confusing (e.g., "android-1234"), so checking MAC addresses is the most reliable identification method.

Pay attention to the connection speed column. For WiFi clients, it will show the current link speed (e.g., 866 Mbps for 5 GHz or 72 Mbps for 2.4 GHz), while for wired clients, it will show 100 Mbps or 1 Gbps. This allows you to quickly understand which frequency a particular device is using. If you see that your modern laptop is connecting at a slow speed, it may be stuck on the congested 2.4 GHz band instead of the 5 GHz band.

The system also highlights the device's status: whether it's currently active or simply reserved in memory. Active clients have an activity time indicator or are green. If a device hasn't transmitted data packets for a long time, it may be marked as inactive but still appear on the allowed list. For a clean experiment and accurate diagnosis, it's recommended to view the list during periods of active use, when all devices are turned on.

Identifying devices by MAC address

The most common problem when auditing a network is not understanding which device a particular MAC address belongs to. Network chip manufacturers have prefixes (the first six characters of the address) assigned to them, which allows you to identify the device brand. For example, addresses starting with 00:1A:2B, may belong to the same manufacturer, and A4:C3:F0 — to another. In the Keenetic interface, you can often manually rename a device for convenience by clicking the pencil or edit icon next to the name.

To accurately identify a device without relying on guesswork, use the process of elimination. Turn off WiFi on all known devices (smartphones, TVs, tablets) and leave only one on. Refresh the router's client list page. The only remaining device is the one you're testing. Write down its MAC address and give it a descriptive name, such as "iPhone_Mom" or "Smart_TV_Living."

To automate the process, you can use online MAC address lookup services (OUI Lookup), where you enter the first three bytes of the address. However, in a home network, the easiest way is to use the router manufacturer's mobile app or your smartphone itself, accessing the WiFi settings to check the physical address against what the router sees. Permanent names will help you to instantly navigate the list in the future.

Why might the device name not be displayed?

Some operating systems (especially new versions of iOS and Android) use a "Private Wi-Fi Address" feature for privacy reasons. This means the device generates a random MAC address for each network, and the router sees it as a new, unnamed device. To fix this, you need to disable the private address feature for your home network in the Wi-Fi settings on the device itself.

Using the Keenetic mobile app

Managing your network from a computer isn't always convenient, especially if you need to check connections on the go. The Keenetic mobile app (available for iOS and Android) offers the full functionality of the desktop version, optimized for smaller screens. After installing the app and linking your router (via Keenetic Cloud or locally), you can access the "Devices" or "Clients" section in the bottom navigation menu.

The app's interface visually groups devices by connection type: wired and wireless. This greatly simplifies the information. You can see not only the connection status but also the current data transfer speed in real time, allowing you to instantly identify heavy users downloading torrents or watching 4K video. The app also allows you to quickly block access or limit speeds for selected clients directly from your phone.

One of the app's key features is the ability to create a guest network or temporary access for visitors. Instead of providing the password for your main network, you can create a temporary profile. The app makes it easy to track who connected through this profile and when, and disconnect them remotely. This improves overall security. cybersecurity your home infrastructure.

Table of connection types and their characteristics

Understanding the differences between connection types helps you correctly interpret the data in the client list. The Keenetic router distinguishes between wired connections (Ethernet), wireless (WiFi 2.4/5 GHz), and virtual interfaces. Below is a table to help you decipher the statuses and speeds you may see in the interface.

The "Designation" column contains interface prefixes that may appear in extended logs or system messages. For the average user, it's important to know that devices connected via Ethernet always have priority for stability. If you see a client with the connection type Wl0 and low speed, it might make sense to move it closer to the router or switch to 5 GHz if the device supports this standard.

The presence of devices with the "Bridge" or "VPN" connection type may indicate configured tunnels or repeaters. If you haven't configured network extenders, the appearance of such entries requires attention. In a normal home network, the majority of clients are WiFi and Ethernet. It is critically important to regularly check the number of active devices against the actual number of gadgets in the home.

Block unknown devices and protect your network

If you find a device you don't recognize in the list of connected clients, you need to act immediately. The first step is to block access. In the Keenetic web interface, next to each device, there's a toggle switch or a block button (often indicated by a cross or an "Internet Access" slider). Clicking this button immediately disconnects the connection and blacklists the device's MAC address.

However, simply blocking your connection doesn't guarantee that an attacker won't try to reconnect by changing the MAC address (although this requires some skill). A more secure method is to change your WiFi password. After changing the password, all devices will be disconnected, and you'll only have to reconnect your devices, entering the new security key. It's recommended to use a complex password that includes mixed-case letters, numbers, and special characters.

It's also worth checking if WPS (Wi-Fi Protected Setup) is enabled. This technology allows you to connect to a network by simply pressing a button or entering a PIN code, but it is considered vulnerable. It's recommended to enable it in the settings menu of Keenetic WiFi routers. disable WPSTo prevent automated password guessing by special utilities, this will close one of the most common loopholes for unauthorized access.

⚠️ Note: Router interfaces and mobile apps are subject to update. Button locations and menu item names may differ from those described depending on the KeeneticOS version. Always consult the latest documentation on the manufacturer's official website if you cannot find the item you need.

Frequently Asked Questions (FAQ)

Why does the client list show more devices than I have?

This is normal. Many modern devices have multiple network interfaces. For example, a smart TV may have a separate module for WiFi and a separate one for Ethernet (even if the cable isn't connected, the interface can be polled). Furthermore, some gadgets create virtual adapters for file or screen sharing (Miracast/AirPlay), which the router can see as separate clients. Smart plugs, light bulbs, and sensors you might have forgotten about also add to your network bill.

Can my neighbor steal my WiFi if I hide the network name (SSID)?

Hiding the SSID isn't a reliable security method. Specialized programs easily detect hidden networks, displaying them as "Hidden Network." If you've hidden your network but left a weak password or enabled WPS, hacking it will only take a few minutes. The only reliable protection is a strong password (WPA2/WPA3) and regularly checking the client list in your Keenetic router.

How can I find out how much traffic a specific device is consuming?

The default client list often only displays the current speed. To view traffic statistics (how many gigabytes have been downloaded per day or month) in KeeneticOS, go to "Monitor" or "System" → "Diagnostics" → "Counters." There, you can see the detailed data volume transferred for each IP or MAC address, if the corresponding accounting function is enabled.

What should I do if the router doesn't show the device name, only the MAC address?

This depends on the device being connected. If it doesn't transmit its hostname during a DHCP request, the router won't be able to identify it. In this case, use a process of elimination (turn off devices one by one) or check the first digits of the MAC address against a manufacturer table online. The Keenetic app often automatically detects devices using a database, which may not be the case in the web interface.

Does the number of connected devices affect internet speed?

Yes, it does. WiFi is a shared-access medium. The more devices actively exchanging data, the more time the router spends coordinating transmissions and the less airtime each device gets. Even if devices are simply "hanging" in the background updating emails, they create a load. For a large number of devices (more than 15-20), it is recommended to use a mesh system or an enterprise-grade access point.
