Using Aircrack-NG Suite (Airmon-NG)

Enabling Monitoring Mode For Wireless Interface Using Airmon-NG
Airmon-ng is used to enable monitoring mode for wireless interfaces to enable them to be able to be use in airodump-ng, aireplay-ng, aircrack-ng, airdrop-ng, airbase-ng and others.

usage: airmon-ng [channel] or airmon-ng

Where:

• indicates if you wish to start or stop the interface. (Mandatory)
  
• specifies the interface. (Mandatory)
  
• [channel] optionally set the card to a specific channel.
• “check” will show any processes that might interfere with the aircrack-ng suite. It is strongly recommended that these processes be eliminated prior to using the aircrack-ng suite. “check kill” will check and kill off processes that might interfere with the aircrack-ng suite.
