The following are the technical requirements for this chapter:

• Kali Linux (https://www.kali.org/)
• VMware Workstation or Oracle VM VirtualBox
• A wireless network interface card (NIC) that supports packet injection

Not all wireless cards support monitor mode and packet injection. However, a minor revision in a chipset can cause the card to not work in monitor mode, and some cards may need the drivers to be compiled and may not work out of the box.

The following is a list of supported external wireless NICs for Kali Linux:

• Atheros: ATH9KHTC (AR9271, AR7010)
• Ralink: RT3070
• Realtek: RTL8192CU
• TP-Link TL-WN722N
• TP-Link TL-WN822N v1 - v3
• Alfa Networks AWUS036NEH
• Alfa Networks AWUS036NHA
• Alfa Networks AWUSO36NH

I would personally recommend using the Alfa Networks AWUS036NHA card.
