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

Have you noticed your internet speed has become slower than usual? Or do you suspect that someone else has connected to your network? Checking your Wi-Fi device list is the first diagnostic step you should take. This procedure not only helps identify unauthorized users but also optimizes network load if too many devices are connected to the router simultaneously.

In this article, we'll cover all possible verification methods—from standard router web interface tools to advanced command line and mobile app methods. You'll learn how to distinguish legitimate devices from suspicious ones, what to do if the connection list isn't displayed, and how to restrict access for unknown devices. We'll pay special attention to the nuances of popular router models (TP-Link, ASUS, Keenetic, MikroTik) and explain why some devices may appear in the list twice.

Regardless of your technical expertise, you'll find a suitable method here—from the simplest (using a mobile app) to the most advanced (analyzing an ARP table). And if you're an office network administrator, we'll provide recommendations for monitoring connections in a corporate environment.

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

The most reliable and accurate method is to access your router's control panel. This method works on any models, regardless of manufacturer, and displays an up-to-date list of connected devices in real time. The main requirement is access to the admin panel (usually requiring the login and password found on the router's sticker).

Instructions for most routers:

  • 🌐 Open your browser and enter in the address bar 192.168.0.1 or 192.168.1.1 (less often) 192.168.8.1 for some models TP-Link). If the IP address doesn't work, find it using the command line (more on that in the next section).
  • 🔑 Enter your login and password (by default it is often admin/admin or admin/empty field). If the data has changed, use the current one.
  • 📊 Go to the section with the list of devices. Its name varies:
    • For TP-Link: DHCP → DHCP Clients or Wireless Mode → Wireless Mode Statistics
    • For ASUS: Network map or Local Area Network → DHCP Clients
    • For Keenetic: Devices (in the main menu)
    • For MikroTik: IP → DHCP Server → Leases
  • 📱 The list will display all devices with the indication IP addresses, MAC addresses, hostname (if available) and connection type (Wi-Fi or Ethernet).

Pay attention to the column MAC address — is a unique identifier for the device. If you see an unfamiliar MAC, but the hostname (for example, Android-1234) seems suspicious, this could be a sign of someone else's device being connected. In the next section, we'll explain how to check the MAC addresses of your devices for comparison.

Find the section with DHCP clients or devices

Check the number of connected gadgets with the expected number

Pay attention to unknown MAC addresses

Check the last activity time of devices-->

⚠️ Attention: Some routers (for example, older models D-Link) may not show a full list of devices in the main tab. In this case, check the section Log or System log — there may be records of new connections.

2. How to find out the router's IP address if the default ones don't work

If neither 192.168.0.1, no 192.168.1.1 If you can't open the control panel, your router has a different local IP address. You can find out in several ways:

Method 1. Via the command line (Windows)

  1. Click Win + R, enter cmd and press Enter.
  2. Enter the command: 
    ipconfig
  3. Find the line Main gateway - this is the IP address of your router.

Method 2. Via the terminal (macOS/Linux)

  1. Open Terminal (on macOS via Spotlight, on Linux - Ctrl+Alt+T).
  2. Enter the command: 
    netstat -rn | grep default
  3. IP address after the word default - This is a gateway.

Method 3. Via smartphone (Android/iOS)

  • 📱 On Android: go to Settings → Wi-Fi, tap on your network and look at the section Gateway or Router.
  • 🍎 On iPhone: Settings → Wi-Fi → (i) next to your network → Router.

If the router's IP address starts with 10., 172.16. or 192.168. with a non-standard third octet (for example, 192.168.45.1), that's fine - just use it to sign in.

3. Checking connected devices via mobile apps

If accessing your router's web interface is inconvenient, you can use official or third-party apps. This method is convenient for a quick check from your phone, but it has a limitation: not all routers support remote management.

Official apps from manufacturers:

  • 📱 TP-Link Tether — for routers TP-LinkDisplays a list of devices, connection speed, and allows you to block unknown devices.
  • 📱 ASUS Router — for devices ASUSThere is a function AiProtection, which automatically detects suspicious connections.
  • 📱 Keenetic — for routers KeeneticDisplays detailed information about each device, including connection history.
  • 📱 Mi Wi-Fi — for routers XiaomiA simple interface with the ability to limit speed for individual devices.

Third-party applications (universal):

  • 🔍 Fing — scans the network and displays all connected devices, even if you don't have access to the router. Works on Android And iOS.
  • 🔍 Network Analyzer — analyzes the local network, determines IP and MAC addresses, and checks ports.
  • 🔍 WiFi Guard — specializes in searching for unauthorized connections.

The advantage of third party apps is that they often show additional information: device model (eg. Samsung Galaxy S22), manufacturer by MAC address, and even approximate location on the network. However, to accurately block third-party devices, you'll still need access to the router.

⚠️ Attention: Apps like Fing They scan the network from your device, so they may not see devices connected via cable (Ethernet) if your phone is on a different subnet. For a complete analysis, it's best to combine methods.

4. How to distinguish your devices from others: MAC address analysis

In the list of connected devices you see MAC addresses - unique identifiers of the form 00:1A:2B:3C:4D:5ETo determine which gadgets are yours and which are not, you need to check the MAC addresses against your devices.

How to find out the MAC address of your device:

Device Instructions MAC address example
Windows
  1. Click Win + R, enter cmd.
  2. Enter ipconfig /all.
  3. Find the line Physical address for the adapter Wireless network.
 A4:BB:6D:1F:8C:99
macOS
  1. Open System Preferences → Network.
  2. Select Wi-Fi → Advanced → Ethernet.
  3. The MAC address is listed as Ethernet ID.
 B8:27:EB:4E:A2:11
Android
  1. Go to Settings → About phone → General information.
  2. Find Wi-Fi MAC address.
 0C:9D:92:E4:F1:02
iPhone/iPad
  1. Go to Settings → General → About.
  2. Scroll to Wi-Fi address.
 F0:18:98:BA:76:5C
Smart TV In the network settings (section Connection information or Wi-Fi Information). 78:59:3E:0A:B1:4D

Compare the MAC addresses of your devices with the list in your router. If you find any discrepancies, it could be:

  • 📱 Guest devices (if you granted access)
  • 🤖 Smart gadgets (lamps, cameras, speakers) that you forgot about
  • ⚠️ External connections (neighbors, hackers)

Pay attention to the first three pairs of characters in the MAC address—they indicate the manufacturer. For example:

  • B8:27:EB — Raspberry Pi
  • 3C:5A:B4 — Google (For example, Nest or Chromecast)
  • 78:31:C1 — Apple
  • 00:0A:F7 — Cisco

A complete list of manufacturers by MAC address can be found on the website IEEE or through a search engine on request MAC vendor lookup.

5. Advanced Methods: Command Line and ARP Table

If the router's web interface is unavailable or you want to obtain data without authorization, you can scan the network via the command line. This method works on Windows, macOS And Linux, but requires basic knowledge.

Method 1. Viewing the ARP table (Windows)

  1. Open Command Prompt (Win + R → cmd).
  2. Enter: 
    arp -a
  3. You will see a list of IP and MAC addresses of devices with which your computer has recently interacted.

Method 2. Scanning the network using nmap (macOS/Linux/Windows with installed Nmap)

  1. Install Nmap (You can download it from the official website) nmap.org).
  2. Open terminal and enter: 
    nmap -sn 192.168.1.0/24

    (replace 192.168.1.0/24 to your subnet, if it is different).

  3. In a few seconds, you will receive a list of all active devices on the network with MAC addresses and manufacturers.

Method 3. Use ping And arp to detect devices

  1. At the command prompt, enter: 
    for /L %i in (1,1,254) do ping -n 1 192.168.1.%i

    (this will send ping requests to all addresses in the range 192.168.1.1–192.168.1.254).

  2. Then enter again arp -ato see the updated list.

These methods are useful if:

  • 🔧 You don't have access to the router (for example, in an office network).
  • 🔍 You suspect that your router has been hacked and its control panel has been compromised.
  • 📊 You need more detailed information than the web interface provides.
⚠️ Attention: Scanning the network using nmap or mass ping This may be considered suspicious activity on corporate networks. While this is safe at home, it's best to obtain administrator permission in the office.
What to do if arp -a shows few devices?

The ARP table only stores devices your computer has recently interacted with. To update it, ping the broadcast address:

ping 192.168.1.255

Then re-run arp -a.

6. How to block unknown devices on Wi-Fi

If you detect unauthorized devices on your network, you can block them. There are several ways to do this, depending on your router's capabilities.

Method 1. Blocking by MAC address (filtering)

  1. Go to your router's control panel.
  2. Find the section Wireless Mode → MAC Filtering (or Security → MAC Filtering).
  3. Add unknown MAC address to blacklist.
  4. Save the settings and reboot the router.

Method 2: Change your Wi-Fi password

The easiest and most secure method is to change your network password. All devices will be disconnected, and only those you give the new password to will be able to connect.

  • 🔑 Find the section in the router panel Wireless Mode → Security Settings.
  • 🔄 Change PSK password (or WPA2-PSK) to a new, reliable one.
  • 📱 Reconnect your devices with a new password.

Method 3: Disabling DHCP for unknown devices

If your router has a manual IP assignment function (Static DHCP or IP Reservation), you can bind IP addresses only to trusted MAC addresses. Other devices will not be able to obtain an IP address and connect to the network.

Method 4. Enabling the "Guest Network" function

If you frequently grant access to guests but don't want to risk your main network:

  • 🛡️ Create a guest network with a separate password in the section Guest network.
  • 🔗 Limit speed and access to local resources (such as printers or network drives).
  • ⏳ Set a time limit (for example, access only for 2 hours).

After blocking unknown devices, it is recommended to:

  • 🔄 Reboot the router.
  • 🔍 Check the connection list again in 10–15 minutes.
  • 📊 Enable connection logging (if available) to track new access attempts.

7. Why might duplicate devices appear in the list of devices?

Sometimes you may see the same gadgets multiple times in the list of connected devices. This isn't always a bug—here are the most common causes:

  • 🔄 Dual connection: the device is connected via both Wi-Fi and cable (Ethernet) at the same time. For example, Smart TV Can use Ethernet for video streaming and Wi-Fi for updates.
  • 📱 Fast Roaming: some smartphones (especially Samsung And Google Pixel) quickly switch between bands 2.4 GHz And 5 GHz, which may appear as two devices.
  • 🖥️ Virtual adapters: laptops with Windows can create virtual network interfaces (for example, for Hyper-V or VPN), which appear as separate devices.
  • 🔄 DHCP Caching: The router may store information about disconnected devices for some time. Refresh the page or reboot the router.

If you see duplicates with identical MAC addresses, this is normal. If the MAC addresses are different, but the names are similar (for example, iPhone-1 And iPhone-2), check if your family members or guests have devices connected to your network.

To reduce the number of "extra" devices in the list:

  • 🔧 Turn it off Fast Roaming in the Wi-Fi settings on your smartphone (if you don’t need high switching speed).
  • 🖥️ Check virtual adapters in Windows Device Manager (chapter Network adapters).
  • 🔄 Set a shorter DHCP lease time in your router settings (for example, 1 hour instead of 24).

8. Monitoring connections in the office network

If you're administering a network in an office or small business, simply checking the device list may not be enough. Here's what we recommend for monitoring:

1. Use professional monitoring tools:

  • 📊 PRTG Network Monitor — tracks all connections, traffic, and even the geolocation of devices.
  • 📈 Zabbix — a free system with notifications about new connections.
  • 🔍 Wireshark — for deep analysis of network traffic (requires skills).

2. Set up VLANs for different departments:

Divide your network into virtual subnets (VLANs) for accounting, sales, guest access, etc. This will restrict access between departments and simplify monitoring.

3. Enable logging on your router:

Find the section in your router settings System Tools → Journal (System Log) and enable connection event logging. Logs can be exported and analyzed.

4. Use radius server for authentication:

For large networks, set up RADIUS-server (for example, FreeRADIUS). This will allow:

  • 🔑 Requires login/password to connect to Wi-Fi.
  • 📅 Restrict access by time (for example, only during business hours).
  • 📊 Maintain detailed connection statistics.

5. Audit your devices regularly:

Create a list of all corporate devices (laptops, printers, IP phones) with their MAC addresses. Check this list against the router data once a month.

For office networks it is also important:

  • 🔒 Disable WPS (vulnerability to brute force attacks).
  • 🔄 Update your router firmware regularly.
  • 📡 Use WPA3 instead of WPA2 (if supported).
⚠️ Attention: In corporate networks, blocking devices by MAC address may be ineffective, as MAC addresses are easily spoofed. A better approach is to use a combination of methods: certificate authentication, VLAN, and traffic monitoring.

FAQ: Frequently asked questions about checking Wi-Fi devices

Is it possible to check connected devices without access to the router?

Yes, but with limitations. You can:

  • Use apps like Fing or Network Analyzer to scan the network from your device.
  • View the ARP table via the command line (arp -a).

However, these methods will only show devices that have interacted with your gadget, and not a complete list of clients connected to the router.

Why do devices with names like "Unknown" or "android-XXXX" appear in the router list?

This is normal—many devices don't broadcast their human-readable hostname to the network. Instead, they display:

  • MAC address (eg. 00-1A-2B-3C-4D-5E).
  • A randomly generated name (eg. android-1234 for smartphones).
  • Word Unknown, if the router could not detect the device.

To identify such a device, compare its MAC address with the addresses of your gadgets.

How to find out what device is hidden behind a MAC address?

There are several ways:

  1. Use online services like MAC Vendor Lookup (For example, macvendors.com) to find out the manufacturer by the first 3 bytes of the MAC address.
  2. If the device is active, try connecting to it via IP through a browser (sometimes a web interface opens, for example, for IP cameras).
  3. Use nmap To scan for open ports: 
    nmap -O [IP address]

    This can help identify the type of device (e.g. printer, camera, smartphone).

Is it possible to track the physical location of a device on the network?

At home, no. Wi-Fi doesn't provide the device's exact location. However, you can:

  • Estimate the distance roughly based on the signal level (some routers have a graph Signal Strength).
  • If the device is connected via cable, identify its port on the router (the web interface usually has a connection diagram).

In corporate networks, specialized equipment is used for triangulation (for example, Cisco CMX), but it is expensive and difficult to set up.

What should you do if an unknown device appears on the network, but you can’t block it?

If your router doesn't allow you to block your device (for example, on a public network), try:

  • 🔄 Change your Wi-Fi password (this will disconnect everyone, including the attacker).
  • 🔒 Enable MAC filtering whitelist (allow connection only to known MAC addresses).
  • 📡 Hide network name (SSID) in the router settings (e
