How to See All Devices Connected to Your Wi-Fi: A Complete Guide

Advantages of mobile applications:

• 🔹 Notifications about new connections (on some models).
• 🔹 Remote control capability (if enabled) Cloud access).
• 🔹 More user-friendly interface compared to the web version.

Flaws:

• 🔸 Not all features are available in the mobile version (for example, fine-tuning Qos or VLAN).
• 🔸 Requires account registration with the manufacturer (for cloud features).

3. Viewing via the command line (Windows, macOS, Linux)

If you don't have access to the router but are connected to its network, you can use system commands to scan the local network. This method is suitable for experienced users and requires basic terminal skills.

For Windows:

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

   arp -a

3. To see active connections, use:
   

   net view

   or for detailed information:
   

   nbtstat -a [IP address]

For macOS/Linux:

1. Open Terminal.
2. Network scanner nmap (install via brew install nmap or sudo apt install nmap):
   

   nmap -sn 192.168.0.0/24

   Replace 192.168.0.0/24 to your subnet (for example, 192.168.1.0/24).

3. To view the ARP cache:
   

   arp -n

What you will see in the results:

• 🔹 IP addresses all devices on the network.
• 🔹 MAC addresses (if they are allowed in the network settings).
• 🔹 Hostnames (if devices broadcast them).

⚠️ Attention: Teams arp -a And nmap will only show those devices that have recently communicated with your PC. A full list may require specialized software (see the next section).

4. Network scanning programs (Wireshark, Angry IP Scanner, Fing)

When standard methods don't provide a complete picture, specialized utilities come to the rescue. They not only display a list of devices, but also analyze traffic, detect data leaks, and even identify gadget models by MAC addresses.

Top 3 Network Analysis Software:

How to use Fing (using Android as an example):

1. Download the app from Google Play or App Store.
2. Connect to your Wi-Fi network.
3. Click Scan - after a few seconds a list of devices will appear indicating:
• 🔹 Manufacturer's name (e.g. Apple Inc. for iPhone).
• 🔹 MAC addresses.
• 🔹 Open ports (may indicate vulnerabilities).

Wireshark — a tool for professionals. It allows you to:

• 🔹 Intercept and analyze all network packets.
• 🔹 Identify ARP spoofing (man-in-the-middle attacks).
• 🔹 Filter traffic by IP, MAC or protocol (for example, HTTP, DNS).

⚠️ Attention: Usage Wireshark On public networks (cafes, airports) it may violate terms of use and privacy laws. On a home network, it's safe.

Check the MAC address by searching on Google (e.g. "00:1A:2B manufacturer")

Disconnect the device through the router control panel (if there is such an option)

Change your Wi-Fi password to a more complex one (at least 12 characters with numbers and special characters)

Enable MAC address filtering in your router settings-->

5. Checking through Windows settings (without third-party programs)

If you are a user Windows 10/11, you can do without additional software. The system provides built-in network monitoring tools, albeit with limited capabilities.

Method 1: Via "Network Settings"

1. Open Settings → Network and Internet → Wi-Fi.
2. Click on the name of your network, then - Properties.
3. Scroll down to the section Network properties - there will be a list here IPv4 addresses (but not all devices!).

Method 2: Via the Network and Sharing Center

1. Right-click the Wi-Fi icon in the tray → Open Network and Internet settings.
2. Select Configuring adapter settings.
3. Double-click on your connection → Wireless network → Intelligence.

Method 3: Through resmon (Resource Monitor)

1. Click Win + R, enter resmon.
2. Go to the tab Network → TCP Connections.
3. Here you will see active connections, but not a complete list of devices on the network.

These methods will only show the devices that communicate with your PC. For a complete network analysis, it's better to use the programs in the previous section.

6. How to view devices on Mac (macOS)

Users MacBook or iMac They can use built-in utilities or third-party applications. Let's consider both options.

Built-in tools:

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

   networksetup -listallhardwareports

   This will show all network interfaces.

3. To view the ARP table:
   

   arp -a

4. For detailed scanning use nmap (install via brew install nmap):
   

   sudo nmap -sn 192.168.1.0/24

• 🔹 Visualizes the network as a graph.
• 🔹 Analyzes signal strength and interference from other networks.
• 🔹 Supports monitoring 2.4 GHz And 5 GHz simultaneously.

The programs are also relevant for macOS Fing And Wireshark, mentioned earlier. They work reliably and offer just as many features as on Windows.

7. How to disable other people's devices from your Wi-Fi

If you find unfamiliar gadgets online, you need to block them. Here 4 ways, how to do it:

Method 1: Change your Wi-Fi password

• 🔹 Go to the router's web interface (see Section 1).
• 🔹 Go to Wireless Network → Security Settings.
• 🔹 Change your password to a complex one (example: W7f#9Kp2$Lm1!).
• 🔹 Save the settings - all devices will be disconnected and will need to reconnect.

Method 2: Filtering by MAC addresses

• 🔹 Find it in your router's control panel Wireless Network → MAC Filter.
• 🔹 Whitelist only the MAC addresses of your devices.
• 🔹 Activate filtering — the router will only allow approved devices through.

Method 3: Disabling via Control Panel

• 🔹 In the list of devices (see Section 1) find something unfamiliar and click Block or Disable.
• 🔹 Some routers (for example, ASUS RT-AX86U) allow you to set a traffic limit for a specific device.

Method 4: Hiding the Wi-Fi network (SSID)

• 🔹 Disable the option in your router settings Broadcast SSID.
• 🔹 Now the network will not be visible in the list of available ones, but you can connect your devices manually.
• 🔹 Minus: This does not protect against targeted attacks if the attacker knows the network name.

⚠️ Attention: MAC address filtering is not the most reliable protection. MAC addresses are easily spoofed using specialized software (for example, Technitium MAC Address Changer). For maximum security, combine this method with password changes and encryption. WPA3.
