Enable Monitor Mode in Linux

Описание: In this short tutorial, you’ll learn how to change your wireless interface into Monitor Mode on Linux step by step using terminal commands. Monitor mode allows your Wi-Fi card to capture all wireless packets in the air — perfect for network analysis, penetration testing, and Wi-Fi auditing.

Commands explained line by line:

sudo iwconfig


👉 Lists all network interfaces and their current modes (Managed, Monitor, etc.)

sudo ifconfig wlan0 down


👉 Disables the wireless interface (replace wlan0 with your adapter name) to apply mode changes safely.

sudo iwconfig wlan0 mode monitor


👉 Switches your wireless interface to monitor mode so it can capture all packets.

sudo ifconfig wlan0 up


👉 Re-enables the interface after changing its mode.

sudo iwconfig


👉 Verify the mode has changed successfully to Monitor.

This method works on Linux distros like Kali, Ubuntu, and Parrot OS. Perfect for cybersecurity learners and ethical hackers.
