Most of wireless pentesting tools need an Wireless USB adapter with wireless injection capabilities.

Wireless Injection

To choose the best usb wifi adapter we need to focus on the chipset used by the card, not all chipsets have all functions necessary to crack a wireless network.

Some chipsets only support monitor mode but doesn’t support injection capabilities to deauthenticate wireless clients from access points and other only support 2.4Ghz frequencies.

When choosing a wifi adapter for wifi hacking to run on a specific operating system like Kali we need to pay attention on three major things:

  • Kernel Support for Layer 1
    • USB Stack – This is very important and can be difficult to troubleshoot the issues. Insure you use the correct driver version to your chipset vendor
    • Transmission Frequencies Supported by drivers
