How to Check How Many Devices Are Connected to Your Wi-Fi: A Complete Guide

Have you ever noticed your internet suddenly slowing down? Or do you suspect that unauthorized devices have connected to your network without your knowledge? Find out the number of devices on a Wi-Fi network — this is the first step to diagnosing connection issues and securing your home or office network. In this article, we'll cover all available methods: from standard router functions to specialized apps and the command line.

Regardless of whether you are using a budget TP-Link TL-WR840N or flagship ASUS RT-AX88U, the instructions below will help you get a complete list of connected gadgets - indicating their IP-addresses, MAC-addresses and even device names. And if you're an office network administrator, these methods will allow you to monitor bandwidth usage and detect unauthorized connections.

It is important to understand that some devices (such as smart bulbs or cameras) may not be connected to the network all the time, but only for data transfer. Therefore, The number of devices in the list can change in real time - especially if the network uses protocols like IoT or MeshWe'll talk about this in more detail as well.

1. Checking via the router's web interface (universal method)

The most reliable way is to log into your router's control panel. This method works on all models, regardless of the manufacturer, but the interface and path to the required section may vary. Below we provide instructions for popular brands.

First you will need:

• 🌐 Find out IP- your router's address (usually it's 192.168.0.1, 192.168.1.1 or 192.168.8.1). It can be found on the sticker on the back of the device.
• 🔑 Enter your login and password to log in (by default, it is often admin/admin or admin/password).
• 🖥️ Connect to the router via cable or Wi-Fi (preferably from a device that is already online).

If you haven't changed your login details but still can't log in, try resetting your router to factory settings using the button Reset (hold it for 10-15 seconds). Attention: This will disconnect all users and reset all settings including the Wi-Fi password!

Instructions for popular brands

On some routers (for example, Xiaomi Mi Router) The list of devices may take up to 1–2 minutes to update. If you don't see new connections, refresh the page or reboot your router.

⚠️ Attention: If your router does not have a client section, the feature may be disabled DHCP (automatic distribution IP-addresses). In this case, check the settings in LAN → DHCP Server.

2. Using mobile applications from the manufacturer

Many modern routers support management via official apps. This is convenient if you need to quickly check the network from your smartphone without accessing the web interface. Apps typically offer a more intuitive interface and notifications about new connections.

List of official apps for popular brands:

• 📱 TP-Link Tether — for routers TP-Link (available for Android And iOS).
• 📱 ASUS Router — for devices ASUS (there is a parental control function).
• 📱 Keenetic — a universal application for all models of the brand.
• 📱 Mi Wi-Fi — for routers Xiaomi (integration with the ecosystem Mi Home).

Advantages of mobile applications:

• ⚡ Quick access to the list of devices without typing IP-addresses.
• 🔔 Notifications about new connections (on some models).
• 📊 Visualize traffic by device (for example, who uses the most internet).

Flaws:

• 🚫 Not all budget models support applications (for example, old ones D-Link or Tenda).
• 🔒 Account registration with the manufacturer is required (for ASUS or Xiaomi).

3. Specialized programs for network scanning

If you don't have access to the router (for example, you're connected to someone else's network with permission) or the web interface is too complex, you can use third-party utilities. They scan the local network and display all active devices.

Top 3 free programs for Windows, macOS And Linux:

• 🖥️ Wireless Network Watcher (from NirSoft) - scans the network and displays IP, MAC, device name, and network card manufacturer. Supports saving reports in .csv.
• 🖥️ Angry IP Scanner — a cross-platform, open-source utility. Can scan ranges. IP and identify open ports.
• 🖥️ Fing — available for Windows, macOS, Android And iOSIn addition to network scanning, it can test internet speed and check ports.

Example of work Wireless Network Watcher:

1. Download the program from official website (portable version does not require installation).
2. Launch WNetWatcher.exe on behalf of the administrator.
3. Click Start Scanning - after a few seconds a list of all devices on the network will appear.

The program will show:

• IP Address — the device's network address.
• MAC Address — unique identifier of the network card.
• Device Name — device name (if it is broadcast).
• Network Adapter Company — the manufacturer of the network adapter (for example, Apple, Samsung, Intel).

⚠️ Attention: Some devices (such as smart plugs or cameras) may not display their network name. In this case, please refer to MAC-address or manufacturer of the adapter.

4. Checking via the command line (for advanced users)

If you prefer to work without a graphical interface, you can use the operating system's built-in tools. This method is suitable for Windows, macOS And Linux, but requires knowledge of basic network commands.

On Windows follow these steps:

1. Open Command line (Win + R → enter cmd → Enter).
2. Enter the command to view ARP-tables (list IP- And MAC-addresses):
   

   arp -a

3. To see only active connections, first ping your entire network range. For example, if your router has the address 192.168.1.1, execute:
   

   for /L %i in (1,1,254) do ping -n 1 192.168.1.%i

   Then re-enter arp -a.

On macOS or Linux use similar commands:

• To scan the network:
  

  nmap -sn 192.168.1.0/24

  (install nmap through brew install nmap or sudo apt install nmap).

• For viewing ARP-tables:
  

  arp -n

Command result arp -a will look like this:

Interface: 192.168.1.100 --- 0x12
Internet Address      Physical Address      Type
192.168.1.1           aa-bb-cc-dd-ee-ff     dynamic
192.168.1.101         11-22-33-44-55-66     dynamic

Where:

• Internet Address — IP-device address.
• Physical Address — MAC-address.
• Type — entry type (dynamic means that the address is assigned through DHCP).

⚠️ Attention: Teams ping And arp will show only those devices that respond to ICMP-requests. Some gadgets (for example, printers or IoT-devices) can ignore ping but still remain online.

5. Testing on routers with OpenWRT/DD-WRT firmware

If your router is running on alternative firmware (OpenWRT, DD-WRT, Tomato), the interface and commands for checking connected devices will be different. These firmware versions offer advanced monitoring capabilities but require more technical knowledge.

Verification methods:

• 🌐 Via the web interface:
  

  Go to Status → LAN or Network → DHCP LeasesHere you will see a list of devices with IP, MAC and the time of address lease.

• 🖥️ Through SSH (command line):
  

  Connect to the router via SSH (for example, through PuTTY) and run:
  

  cat /tmp/dhcp.leases

  or for a complete list of active clients:
  

  arp -n | grep -v 'incomplete'

Advantages of alternative firmware:

• 📈 Detailed traffic statistics for each device.
• 🔒 Blocking option MAC-addresses through firewall.
• 🛠️ Flexible settings DHCP (for example, reservation IP for certain devices).

Flaws:

• ⚠️ Risk of bricking the router if the firmware is incorrect.
• 📚 Documentation review is required (e.g. OpenWRT Wiki).

How to reserve an IP address for a device in OpenWRT?

To fix the static IP for the device (for example, for a printer or NAS), edit the file /etc/config/dhcp:

1. Connect via SSH.
2. Open the file: vi /etc/config/dhcp.
3. Add a block:

   config host
   option name 'printer'
   option mac 'AA:BB:CC:DD:EE:FF'
   option ip '192.168.1.100'

4. Save (:wq) and restart DHCP:

   /etc/init.d/dnsmasq restart

6. Monitoring via parental controls or guest network

Many modern routers support the function parental control, which not only restricts access to content but also logs device activity. This is useful if you want to not only see a list of connected devices but also monitor their traffic.

How to enable parental controls (using an example) ASUS RT-AX88U):

1. Go to Adaptation → Parental Controls.
2. Click Add Profile and specify a name (for example, "Children").
3. Select devices from the list or add them by MAC-address.
4. Set time or content limits.

Advantages of the method:

• 🕒 Connection time control (for example, disconnecting the Internet after 10:00 PM).
• 📊 Statistics on visited sites and consumed traffic.
• 🔒 Blocking unwanted devices.

An alternative way is to use guest networkMost routers allow you to create a separate network for guests with limited access to local resources. This will allow you to:

• 🛡️ Isolate the main network from outside devices.
• 📋 Maintain separate records of connected gadgets.
• ⏱️ Limit speed or access time.

⚠️ Attention: If you use Mesh-system (for example, Google Nest Wi-Fi or TP-Link Deco), the list of devices may be duplicated on different nodes. In this case, focus on the unique ones. MAC-addresses.

7. Detect hidden devices and protect your network

Sometimes there may be devices on the network that don't appear in the standard lists. These may include:

• 🕵️‍♂️ Devices with disabled DHCP (manual IP).
• 📡 Smart gadgets connected directly to the router via Wi-Fi Direct.
• 🖥️ Computers in "sleep" mode, but with an active network connection.

How to detect such devices:

1. Port scanning by using Nmap or Angry IP Scanner (will show all active IP, even without DHCP).
2. Viewing the router log (Logs or System Log) - some models record all connections, including unsuccessful ones.
3. Disabling all known devices and checking the remaining traffic through Bandwidth Monitor (If there is traffic, but no devices, someone connected without your knowledge).

If you find a suspicious device:

• 🔍 Check it out MAC-address via MAC Vendors.
• 🚫 Add him to your blacklist (MAC Filtering) in the router settings.
• 🔑 Change your Wi-Fi password to a more complex one (it is recommended to use WPA3).
• 🛡️ Turn on WPS only when necessary (this protocol is vulnerable to hacking).

Additional security measures:

• 🔄 Update your router firmware regularly (vulnerabilities are fixed).
• 📵 Disable remote router management (Remote Management).
• 🌐 Use VPN to access the router settings from the outside.

FAQ: Frequently asked questions about connected devices

Is it possible to find out what websites a device visits on my network?

Yes, but this requires additional settings. On routers with firmware OpenWRT or DD-WRT You can enable traffic logging (Logd). Also some models (for example, ASUS With AiProtection) show statistics of visited websites. For a deep analysis, you will need a program like Wireshark (but this violates the privacy of other network users).

Why is there an unknown device in the device list? MAC-address with the name "Unknown"?

This could be:

• Smart device (IoT), which does not broadcast its name.
• Guest device connected via WPS.
• Hacked connection (if you don't recognize the device, block it).

Check the address via MAC Vendors - this will help to identify the manufacturer.

How to limit the number of connected devices?

Most routers have a feature Maximum DHCP Users or Client LimitFor example, on TP-Link go to DHCP → DHCP Settings and specify the maximum number of clients. You can also use MAC Filteringto allow only certain devices to connect.

Is it possible to see connected devices on public Wi-Fi?

No, not if you don't have access to the router. On public networks (cafes, airports), the administrator can see all connections, but the average user cannot. To analyze your network in such conditions, you can use programs like Fing, but they will only show devices on your local subnet (if it is isolated).

Why is the number of devices in the web interface and in the program Wireless Network Watcher is it different?

This is normal. The router's web interface shows the devices that have received IP through DHCP, A Wireless Network Watcher scans the entire local network, including devices with manual settings IPThe difference may also be due to:

• Devices in "sleep" mode (they may not respond to ping).
• IoT- gadgets that are connected periodically.
• Delays in updating the list in the router.
