How to Check How Many Devices Are Connected to Your Wi-Fi Router: All Methods

Have you noticed that your internet has become slower and pages are loading slowly? One possible reason is... unauthorized connection to your Wi-Fi network. Even if you're sure you're the only one who knows the password, your neighbors can connect without your knowledge: through router vulnerabilities, password leaks, or simple combinations like 12345678The first step to solving the problem is find out the exact number of devicesthat are currently using your Wi-Fi.

In this article we will look at all available methods checking connected clients - from standard router menus to advanced methods through telnet and third-party utilities. You'll learn how to distinguish legitimate devices from fake ones, why some gadgets may appear twice, and what to do if the connection list is empty, even though someone is clearly using the internet. These instructions are suitable for routers. TP-Link, ASUS, Keenetic, Xiaomi, MikroTik and other popular brands.

Important: If you rent a router from a provider (for example, Rostelecom or Beeline), some functions may be blocked. In this case, use the alternative methods from the last sections of the article.

1. Checking via the router's web interface (the easiest way)

Most modern routers display a list of connected devices directly in the control panel. The interface may vary depending on the model, but the general process is the same:

1. Connect to the router via Wi-Fi or cable Ethernet.
2. Open your browser and enter in the address bar 192.168.0.1 or 192.168.1.1 (the exact address is indicated on the router sticker).
3. Enter your login and password (by default it is often admin/admin or admin/empty).
4. Find the section with active clients (names may differ).

Here's where to find a list of devices in popular firmware:

• 🔹 TP-Link: Wireless Mode → Wireless Mode Statistics or DHCP → DHCP Client List
• 🔹 ASUS: Network map (tab Clients) or Local Network → DHCP Server
• 🔹 Keenetic: Devices (in the main menu) or Home Network → Device List
• 🔹 Xiaomi: Status → Clients or Wi-Fi → Connected devices
• 🔹 MikroTik: IP → DHCP Server → Leases or Wireless → Registration Table

In the list you will see:

• 📱 IP address devices (for example, 192.168.0.103)
• 🔤 MAC address (unique identifier, for example 00:1A:2B:3C:4D:5E)
• 🖥️ Host name (how the device identified itself on the network, for example iPhone-12-Pro)
• 📶 Connection type (Wi-Fi 2.4 GHz / 5 GHz / Ethernet)

⚠️ Note: Some routers only show devices that have received an IP via DHCP. If a device has a static IP, it may not appear in the list. To see all connections, check the section ARP table (usually in Local area network or Net).

2. How to distinguish your devices from others

Did you see 10 devices on the list, but you only have a smartphone, laptop, and TV at home? Don't panic—not every connection indicates a hack. Here's what could be creating "extra" entries:

• 🔄 Dual connections: one device can use both 2.4 GHz and 5 GHz Wi-Fi at the same time (e.g. modern smartphones).
• 🖨️ Hidden gadgets: printers, smart light bulbs (Xiaomi Yeelight, Philips Hue), CCTV cameras often connect automatically.
• 🎮 Game consoles: PlayStation, Xbox or Nintendo Switch can remain online even in sleep mode.
• 🔄 Cached records: The router can store data about disconnected devices for some time (refresh the page after 5-10 minutes).

To identify your devices:

1. Check it out MAC addresses: They are unique to each gadget. Find your smartphone's MAC in the Wi-Fi settings (on Android: Settings → About phone → General information → Wi-Fi MAC address).
2. Compare host names: often they contain the device model (eg. Samsung-Galaxy-S22).
3. Disconnect your gadgets from the network one by one and watch which connection disappears from the list.

If you find a suspicious device:

• 🔒 Change your Wi-Fi password complex (at least 12 characters with letters, numbers and signs).
• 🔄 Enable MAC filtering (in the router settings, add only your addresses to the white list).
• 🛡️ Update your router firmware — many vulnerabilities are fixed in new versions.

3. Checking via a mobile app

Router manufacturers release official apps that simplify network management. They often display a list of connected devices in a more convenient format than the web interface. Here are the most popular utilities:

Advantages of mobile applications:

• 📱 Real-time notifications about new connections.
• 📊 Traffic visualization (how much each device consumes).
• 🔒 Quickly block suspicious clients with one tap.

⚠️ Please note: Some apps (eg. Mi Wi-Fi) require registration through a manufacturer account. If you don't want to create an account, use the web interface or alternative methods in the following sections.

4. Advanced Method: Command Line (Windows/Linux/macOS)

If you don't have access to your router settings (for example, if you rent it from a provider), you can find out the number of connected devices via command line your computer. This method will only show devices on your local network, not those connected directly to the router via Wi-Fi (if you're using a cable).

For Windows:

1. Open Command line (Win + R → enter cmd → Enter).
2. Enter the command:

   arp -a

3. You will see a list of IP and MAC addresses. Exclude the router address (usually 192.168.0.1 or 192.168.1.1) - the rest relate to devices on the network.

For Linux/macOS:

1. Open Terminal.
2. Enter the command:

   nmap -sn 192.168.0.0/24

   (replace 192.168.0.0 to your subnet, if it is different).

3. The system will scan the network and display all active hosts.

What do the results mean:

• 🔢 Dynamic in the conclusion arp -a — the device received an IP automatically (DHCP).
• 🔢 Static — IP is assigned manually (perhaps it is your server or printer).
• ⚠️ If you see MAC addresses with prefixes 00:00:5E (multicast) or 33:33 (IPv6), they can be ignored - this is service traffic.

How to find out your subnet?

Open command prompt and type ipconfig (Windows) or ifconfig (Linux/macOS). Find the line IPv4 address (For example, 192.168.0.100). Your subnet is the first three octets (in the example - 192.168.0).

5. Using third-party utilities to scan the network

If standard methods don't provide a complete picture, use specialized programs. They scan the network and display all connected devices, including those not visible in the router's web interface.

Top 5 Network Analysis Utilities:

• 🖥️ Advanced IP Scanner (Windows) - free, scans ports and shows device manufacturers by MAC.
• 🍎 LanScan (macOS) - simple interface, export reports to CSV.
• 🐧 Angry IP Scanner (Windows/Linux/macOS) — cross-platform, supports plugins.
• 📱 Fing (Android/iOS) - a mobile application with notifications about new devices.
• 🔍 Wireshark (advanced level) - analyzes traffic in real time.

Example of working with Advanced IP Scanner:

1. Download the program from official website and install.
2. Start scanning (button Scan).
3. In 1-2 minutes you will see a list of all devices with IP, MAC, name and manufacturer.
4. Export the report to CSV for further analysis.

Check the MAC address in the manufacturers database (for example, on the website macvendors.com)|

Turn off all your gadgets and see if the suspicious connection disappears|

Change your Wi-Fi password to a more complex one (use WPA3, if the router supports it)|

Turn on the function Hide SSID (doesn't protect 100%, but reduces the number of accidental connections)-->

⚠️ Attention: some antivirus programs (for example, Kaspersky, ESET) may block network scanners, considering them potentially dangerous. Add the program to the exceptions list or temporarily disable protection during the scan.

6. Check through Telnet/SSH (for advanced users)

If your router supports remote management via Telnet or SSH, you can get a list of connected devices directly from the system. This method is suitable for MikroTik, Ubiquiti, DD-WRT and other advanced firmware.

Instructions for MikroTik:

1. Connect to the router via WinBox or SSH (use login/password from the web interface).
2. Enter the command:

   /ip dhcp-server lease print

   - this will show devices that have received an IP via DHCP.

3. For a complete list (including static IPs) use:

   /ip arp print

For routers with firmware DD-WRT:

1. Connect via SSH (port 22 by default).
2. Enter:

   cat /tmp/dhcp.leases

   — list of leased IPs.

3. For ARP table:

   arp -a

Critical information: If you see MAC addresses with the prefix in the command output 00:00:00, FF:FF:FF or 33:33:00These aren't actual devices, but rather service entries (multicast, broadcast). They can be ignored.

7. How to automate connection monitoring

Manual checking is tedious if you need to monitor your network constantly. Fortunately, there are ways to automate this:

• 📊 Setting up notifications on your router: many models (ASUS, Keenetic) can send email or push notifications when a new connection is established. Look for this feature in the section Security or Notifications.
• 🤖 Python scripts: using the library scapy You can write a script that will scan the network and send reports by email. Code example:

  from scapy.all import ARP, Ether, srp
  def scan_network(ip_range):
  arp = ARP(pdst=ip_range)
  ether = Ether(dst="ff:ff:ff:ff:ff:ff")
  packet = ether/arp
  result = srp(packet, timeout=3, verbose=0)[0]
  devices = []
  for sent, received in result:
  devices.append({'ip': received.psrc, 'mac': received.hwsrc})
  return devices
  print(scan_network("192.168.0.0/24"))

• 📱 Mobile applications with monitoring: Fing or Network Scanner can monitor the network in the background and alert you to changes.

For owners Ubiquiti UniFi or TP-Link Omada:

• Use built-in dashboards with activity graphs.
• Set up guest network with a time limit - all unknown devices will be automatically turned off.
• Turn on two-factor authentication to access the router settings.

FAQ: Frequently asked questions about connected devices

Why does the router list show more devices than there actually are?

This can happen for several reasons:

• 🔄 Devices with dual connection (for example, a smartphone uses 2.4 GHz and 5 GHz simultaneously).
• 🖥️ Virtual machines or Docker containers on your PC.
• 🔄 Cached DHCP entries — the router stores data about disconnected devices for some time.
• 📡 Neighbors on Ethernet (for example, a Smart TV or game console connected via cable).

To clear the list, reboot your router or manually refresh the clients page.

Is it possible to find out what websites a connected device visits?

Yes, but this requires additional settings:

• 🔍 On routers with firmware DD-WRT or OpenWRT turn on traffic log in the section Status → Logs.
• 🖥️ Use it Wireshark for packet analysis (requires skills).
• 📊 Install Pi-hole on Raspberry Pi — it blocks ads and keeps logs of requests.

⚠️ Please note: collecting traffic data from other devices may violate privacy laws (e.g., Article 137 of the Russian Criminal Code on violation of the privacy of correspondence). Use this feature only for legitimate purposes (e.g., parental control).

How to block someone else's device without changing the password?

There are several ways:

1. MAC filtering:
   • Find the MAC address of the stranger in the list of connected devices.
   • In the router settings, add it to blacklist (chapter Wireless Mode → MAC Filter).
2. IP to MAC Binding:
   • In the section DHCP create a static binding of a non-existent IP (eg. 192.168.0.250) to the stranger's MAC.

Time limit:

• Turn on the function Parental control and lock your device 24/7.

The downside of these methods is that an experienced user can spoof the MAC address. The most reliable change your Wi-Fi password and turn on WPA3.

Why are some devices not showing up in the router list?

Possible reasons:

• 🔌 The device is connected via cable, and you're only looking at wireless clients. Check the section Local area network or ARP table.
• 🔒 At the gadget static IP, not received via DHCP. Look for it in ARP-table.
• 🛡️ The device uses VPN or Tor - it can mask its presence.
• ⚡ At the router firmware failure - try rebooting it.

If the problem persists, scan the network using Advanced IP Scanner or nmap.

Is it possible to find out the number of connected devices without access to the router?

Yes, but with restrictions:

• 🖥️ Use it command line (arp -a or nmap), as described in section 4.
• 📱 Install on your smartphone scanner app (For example, Fing).
• 🔌 Connect to the network via Ethernet - this way you will see more devices on the local network.

Please note: these methods will only show devices in your network segment. If your router separates clients (for example, a guest network), you won't see other subnets.
