Who's Connected to My Wi-Fi? 7 Ways to Check the List of Devices on Your Network

Have you noticed your internet has slowed down, and your data usage is unusually high? Perhaps unauthorized devices have connected to your Wi-Fi network—neighbors, guests who forgot to disconnect, or even hackers. In this article, we'll look into it. All available methods for checking connected gadgets, from standard router functions to advanced network utilities.

It doesn't matter what kind of router you have - TP-Link, ASUS, Keenetic or MikroTik — the instructions will work for most models. We'll also tell you how detect hidden connections that are not displayed in the router's web interface, and what to do if you find an unknown device. Let's start with the simplest method!

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

Any modern router maintains a list of connected devices. To view it, simply go to the control panel. Here are the universal instructions for most brands:

1. Connect to the Wi-Fi network you want to test (or use an Ethernet cable).
2. Open your browser and type in the address bar 192.168.1.1 or 192.168.0.1If you can't access the router, check the IP address on the router's sticker.
3. Enter your login and password (usually admin/admin, if you haven't changed it).
4. Find the section with connected devices (names may differ).

Where to find a list in popular firmware:

• 🔹 TP-Link: Wireless Mode → Wireless Mode Statistics or DHCP → DHCP Client List
• 🔹 ASUS: Network map (main page) or Local Network → DHCP Server
• 🔹 Keenetic: List of devices (on the main screen) or Home Network → Devices
• 🔹 Zyxel: Wi-Fi Network → Status → Clients

In the table you will see MAC addresses, IP addresses and device names. Pay attention to unknown devices—they can be blocked directly from the interface (usually there's a "Block" or "Disable" button).

2. Using mobile applications (for smartphones)

If accessing your router settings is inconvenient, you can use specialized apps. They scan the network and display all connected devices along with additional information (manufacturer, device type).

Top 3 verified apps:

• 📱 Fing (Android/iOS) — identifies device models by MAC address, shows open ports and vulnerabilities.
• 📱 WiFi Analyzer (Android) - A free tool with network visualization and client list.
• 📱 NetScan (iOS) - scans the network and saves connection history.

How to use Fing:

1. Install the app and connect to your Wi-Fi network.
2. Click "Scan" - in 10-20 seconds a list of devices will appear.
3. Click on an unknown gadget to see its MAC address, manufacturer, and connection history.

The advantage of apps is that they work even if you don't have access to the router (for example, on a guest network). However, some features (such as device blocking) require root rights on Android or jailbreak on iOS.

3. Commands for Windows (via command line)

On a computer with Windows You can see connected devices without third-party programs. To do this, use the command line and a utility. arp (Address Resolution Protocol).

Instructions:

1. Open Command line as administrator (click Win + X → Terminal (Administrator)).
2. Enter the command to view all IP and MAC addresses on the network:

   arp -a

3. To see only active connections, first ping the broadcast address:

   ping 192.168.1.255

   Then enter again arp -a.

As a result, you will receive a table with IP and MAC addresses. To find out the device manufacturer by MAC, use the service MAC Vendors Lookup (enter first 6 characters of MAC).

Limitation of the method: arp -a Shows only those devices that have recently communicated with your PC. For a full network scan, it's best to use Advanced IP Scanner or Angry IP Scanner.

Check your Wi-Fi connection|Open a command prompt as administrator|Ping 192.168.1.255|Run arp -a|Check MAC addresses against known devices

4. Network scanning on macOS and Linux

Users Mac And Linux They can use built-in network utilities to analyze connected devices. Let's consider both options.

For macOS (Terminal):

1. Open Terminal (Command + Space → enter "Terminal").
2. Enter the command to scan the local network:

   nmap -sn 192.168.1.0/24

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

3. In a few minutes you will receive a list of IP and MAC addresses.

For Linux (Ubuntu/Debian):

1. Install nmap, if it is not there:

   sudo apt install nmap

2. Start the scan:

   sudo nmap -sn 192.168.1.0/24

3. For detailed information, add a flag -O (OS definition):

   sudo nmap -O 192.168.1.100

   (Where 192.168.1.100 — IP of an unknown device).

Nmap — a powerful tool that displays not only active devices but also open ports, OS versions, and potential vulnerabilities. However, for beginners, the output may seem complex. In this case, use graphical alternatives:

• 🖥️ Wireshark - deep traffic analysis (requires skills).
• 🖥️ Zenmap — a graphical shell for nmap.

What to do if nmap does not show all devices?

If the scan did not detect some gadgets, try:

1. Disable the firewall on your router temporarily.

2. Use the `-Pn` flag to scan without ping:

```bash

sudo nmap -Pn -sn 192.168.1.0/24

```

3. Check if your antivirus is blocking network requests.

5. Checking via the router menu on your phone (without a PC)

If you only have a smartphone at hand, you can access the router settings through a mobile browser. The process is the same as on a PC, but with a phone-specific twist:

1. Connect to the Wi-Fi network you are testing.
2. Open your browser (preferably Chrome or Firefox) and enter the router IP (for example, 192.168.1.1).
3. Enter your login and password. If you don't know it, look on the router's sticker or in the instructions.
4. Find the clients section (see first method).

On some routers (for example, Keenetic) There's a mobile app for network management. It's more convenient than a browser because it's adapted for touchscreens. Examples of apps:

• 📲 Keenetic — official application for iOS/Android.
• 📲 TP-Link Tether — for TP-Link routers.
• 📲 ASUS Router — for ASUS devices.

Warning: If you are connected to the network via guest Wi-Fi, access to the router settings may be restricted. In this case, use the methods from second section (mobile applications).

6. Traffic analysis using specialized programs

For advanced users who want to not only see a list of devices but also analyze their activity, traffic monitoring programs are suitable. They show which websites connected devices visit, how much traffic they consume, and even block unwanted connections.

Best programs for analysis:

Example of use GlassWire:

1. Download and install the program from official website.
2. Launch it and go to the tab Network.
3. In the section Devices You will see all connected gadgets with an indication of the traffic consumed.
4. To lock a device, right-click on it and select Block.

NetCut - a more aggressive tool that can disconnect devices from the network without access to the router. However, its use can disrupt network operation if used carelessly.

7. Detect hidden connections (if the device is not visible in the list)

Sometimes attackers connect to the network but don't show up in the router's default lists. This can happen due to:

• 🔌 Usage MAC address spoofing (substitution for the address of a trusted device).
• 🔌 Connections via WPS (vulnerable rapid setup protocol).
• 🔌 Attack type " Evil Twin " (cloning your network).

How to detect such connections:

1. Check your router logs:

   - Find the section in the web interface System Tools → Logs or Journal.

   - Look for records of new connections or authentication errors.

2. Use Wireshark for packet analysis:

   - Start capturing traffic on your Wi-Fi channel.

   - Filter packets by protocol DHCP or ARP - They will show all connection requests.

3. Disable WPS:

   - Find it in your router settings WPS and deactivate it. This protocol is easy to hack even without a password.

If you suspect your network has been hacked, immediately:

⚠️ Attention: Change your Wi-Fi password to a complex one (at least 12 characters, with numbers and special characters). Disable remote router management (WAN Access) and update the firmware to the latest version.

What to do if you find an unknown device?

Found a gadget online that you don't recognize? Follow these steps:

1. Check its legitimacy:

   - Ask your household members if they have connected a new device (smart watch, speaker, game console).

   - Check the MAC address in the service MAC Vendors - it will show the manufacturer.

2. Lock your device:

   - In the router settings, find it in the list of clients and click "Block" or "Disconnect".

   - Alternatively, add his MAC to the blacklist (MAC Filtering).

3. Change your Wi-Fi password:

   - Use a password generator (eg. Passwords Generator).

   - Recommended format: WPA3-Personal (if the router supports it).

4. Enable notifications about new connections:

   - In some routers (for example, ASUS) there is a function of notifications about new devices.

   - Configure it in the section Security → Notifications.

If an unknown device reappears after being blocked, it may mean that:

• 🔄 Your Wi-Fi password has been compromised (for example, someone has seen it).
• 🔄 There is a "hole" in the network - a vulnerability in the router firmware or an enabled WPS.
• 🔄 Someone is using repeater or bridge to bypass the blocking.

⚠️ Attention: If after changing the password and blocking the MAC address the unknown device continues to connect, reset the router to factory settings (Reset button on the case) and set it up again.

FAQ: Frequently asked questions about connected devices

Is it possible to see what websites a connected device is visiting?

Yes, but for this you need special programs like Wireshark or GlassWireA standard router doesn't display browsing history, only the traffic consumed. Keep in mind that intercepting traffic may violate privacy laws if you analyze other people's devices without their consent.

Why are devices that are not at home displayed in the router list?

These could be:

• Devices that were previously connected but did not disconnect correctly (the router stores them in the cache).
• Neighboring gadgets, if you have a weak password and they connected automatically.
• Viruses or botnets using your Wi-Fi for DDoS attacks.

Refresh the client list (usually there is a "Refresh" button) or reboot the router.

How to block a device permanently?

The most reliable way is to add its MAC address to the blacklist (MAC Filtering). To do this:

1. Find the MAC of the unknown device in the client list.
2. Go to Wireless Mode → MAC Filter (the name may differ).
3. Add the address to the block list and save the settings.

The downside of this method is that if the attacker changes the MAC, he will be able to connect again.

Is it possible to find out who is connected to my Wi-Fi if I'm not at home?

Yes, if your router has:

• Cloud management (eg TP-Link Cloud or ASUS DDNS).
• Support for remote access via the application.
• Tuned VPN server for a secure connection.

Without these features, remote verification is not possible for security reasons.

What should I do if my router doesn't show a list of connected devices?

Possible causes and solutions:

• Outdated firmware - update it in the section System Tools → Software Update.
• DHCP is disabled — check that the DHCP server is enabled in the LAN settings.
• Router malfunction - Perform a factory reset.

If the problem persists, use third-party programs to scan the network (see third section).
