airmon-ng [start|stop|check] [interface] [channel]

airmon-ng manages wireless interfaces for monitor mode operation. Monitor mode allows capturing all wireless packets in range, not just those addressed to your device, which is required for wireless security auditing.
The tool can identify and kill processes that might interfere with monitor mode operation, such as NetworkManager and wpa_supplicant.

start interface

Enable monitor mode on interface

Disable monitor mode

List processes that may interfere

Kill interfering processes

Lock interface to specific channel

Without arguments, airmon-ng lists:
- Interface name
- Chipset information
- Driver in use
- Current mode (managed/monitor)

Enabling monitor mode disconnects from any connected network. Some drivers don't support monitor mode. Killing interfering processes may disable normal WiFi connectivity until restarted.

airmon-ng is part of the aircrack-ng suite, evolved from earlier airmon scripts. The "-ng" version was released in 2006 with improved driver support and process management.
