To use “iwlist The “channel” command sets the current channel.
For madwiFi-NG-driven network CARDS, the access point displays the MAC address of the network card. At this time, the interface name and mode are displayed. The “iwconfig” command can be used to verify whether the network card is in monitor mode. If ATH1, ATH2, and so on are also running, you need to stop them before you can do the above: airmon-ng stop ath1Ĭhannels can be set by adding the number of channels after the command: airmon-ng start wifi0 9 The access point displays the MAC address of the network card (only in the Madwifi-NG driver, not in other drivers). Also note that essid, Nickname, and Encryption are kept in an unset state. We can see that ATH0 is now in Monitor mode. Link Quality=0/94 Signal level=-96 dBm Noise level=-96 dBm Mode:Monitor Frequency:2.452 GHz Access Point: 00:0F:B5:88:AC:82īit Rate=2 Mb/s Tx-Power:18 dBm Sensitivity=0/3 Now enter “iwconfig” and the screen will display: lo no wireless extensions. We can see that ath0 is no longer there, and then we can turn on Monitor mode on ath0 using the following command: airmon-ng start wifi0Īth0 Atheros madwifi-ng VAP (parent: wifi0) (monitor mode enabled)
Now, enter “iwconfig” and the screen will display: lo no wireless extensions.
The screen will say: Interface Chipset DriverĪth0 Atheros madwifi-ng VAP (parent: wifi0) (VAP destroyed) If you want to use ATH0 (which is already in use), first: airmon-ng stop ath0

The following describes how to place the MADwifi-NG-driven network card in Monitor mode. (mac80211 monitor mode vif disabled for wlan0mon)ĭon’t forget to restart the Network Manager, usually by using the following command: service network-manager start (mac80211 station mode vif enabled on wlan0) Phy0 wlan0mon ath9k_htc Atheros Communications, Inc. Turn off monitor mode ~# airmon-ng stop wlan0mon (mac80211 station mode vif disabled for wlan0)Īs we can see, Airmon-ng has created a new interface for us, Wlan0mon, and lists some processes that might affect Aircrack-ng.ĥ. (mac80211 monitor mode vif enabled for wlan0 on wlan0mon) The following command will stop network managers and then kill all processes affecting aircrack-ng: ~# airmon-ng check killīefore starting monitor mode, network managers (airmon-ng check kill) need to be turned off: ~# airmon-ng start wlan0 If airodump-ng, aireplay-ng or airtun-ng stops working afterĪ short period of time, you may want to kill (some of) them! You can also check manually by using the following command: ~# airmon-ng checkįound 5 processes that could cause trouble. When we place the network card in monitor mode, we automatically check the processes affecting aircrack-ng. Phy0 wlan0 ath9k_htc Atheros Communications, Inc. Check the status of each interface: ~# airmon-ng Means to turn on or off an interface (force) Specify the interface (force) to set the network card to a specific channel (optional) “Check lists all processes that affect aircrack-ng work, and it is highly recommended to stop these processes when using the Aircrack-ng kit.” Check Kill “lists and kills processes that affect Aircrack-ng.ġ. Enter the airmon-ng command with no arguments, and the current interface state is displayed. Airmon-ng is used to convert the wireless interface between managed and Monitor modes.
