The chipset inside a wireless adapter dictates everything: which driver it uses, whether it supports monitor mode and packet injection, and which attacks are possible. PEN-210 covers identifying the exact chipset and driver of an adapter so you can choose the right tool and troubleshoot when injection or monitor mode fails. On the exam you are given an adapter, and knowing how to interrogate it quickly saves time.

## Identifying Chipsets and Drivers

USB and PCIe adapters are enumerated differently: lsusb and lspci list connected hardware, while airmon-ng, ethtool, and the loaded kernel module reveal the active driver bound to an interface. Mapping the chipset model (for example RTL8812AU, AR9271, MT7612U) to its driver tells you whether the adapter supports injection out of the box or needs a manually installed driver, and points to the fix when a capture is not working.
