WLAN Security Megaprimer Part 2: Bands, Channels And Sniffing

In Part 2, we will learn how to setup our wireless card into monitor mode and start sniffing the waves. We will see that fundamentally wired and wireless sniffing is different. In the case of wireless, we can only sniff on one channel at a time. This channel needs to be chosen from the bands our card can operate in. Also, it is possible to use channel hopping to quickly sample all the wireless networks and clients in the airspace.
