WiFi Data Capturing on 2 Channels - Beginner Guide

Product: Linux Commands: airodump-ng, iw Overview I do not like to use the airmon-ng command to change the WiFi device name to follow its original device name, which it is hard for me to remember, e.g. device name wlp0s12u1. So in this post, I will use "iw" utility (previously called iwlist, iwconfig) that bundled with Fedora 41, or RedHat RHEL 9, to configure the WiFi adapter in monitor mode with my preferred device name.  The benefits are: I can define my own device name, e.g. wlan0mon I can use pre-defined device name in script "iw" utility offers more information in the WiFi network adapter as well as LAN NIC USB device detection is more accurate It can shows device name of my USB WiFi dongle without additional typing It can creates additional logical device that other new users like, such as wifi1, capture2024 Procedure Login to Linux as root, or use one of the following su - sudo su - Find out the physical device ID using "iw dev" command It will dis...
