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
