How to Easily Check Connected Devices on Your Network: A Step-by-Step Guide

Understanding the number of devices connected to your network is crucial for both managing your internet speed and ensuring your Wi-Fi security. Whether you’re dealing with a limited bandwidth plan or suspecting unauthorized access, monitoring connected devices can provide clarity and peace of mind. Surprisingly, it’s not just your phones and laptops that consume network resources; smart TVs, and various IoT (Internet of Things) devices also share your Wi-Fi connection.

Simple Steps to Monitor Your Network

To effectively check your network connections, we recommend using a user-friendly tool that works across both Windows and Linux platforms. For this guide, we’ll focus on utilizing EtterCap on a Linux system, which, despite its primary function for network attacks, serves as an excellent tool for network monitoring due to its simplicity and comprehensive features.

Setting Up EtterCap on Linux

  1. Install EtterCap: Start by installing the application via terminal with the command: sudo apt install ettercap-common.
  2. Launch EtterCap: After installation, run EtterCap to access its graphical interface, eliminating the need for further terminal commands.
  3. Select Your Network Interface:
    • Use ifconfig to list your active network interfaces.
    • Identify and select the primary interface connected to your network within EtterCap.

Identifying Connected Devices

Upon starting EtterCap and selecting the appropriate network interface, initiate the scan by clicking on the “scan” icon. This action triggers the display of all connected devices, listing their MAC and IP addresses. This comprehensive view helps in identifying each connected device.

How to Identify Unknown Devices

If you encounter unfamiliar devices, identifying them is straightforward:

  • Windows: Use ipconfig /all in CMD to find your device’s MAC address.
  • Mobile Devices: Navigate to “Device information” in your device’s settings to find both IP and MAC addresses under “Status”.
  • Linux: Execute ip adder show and look for the “link/ether” parameter to see your device’s MAC address.
