 ==== Typical Uses ====
-To start wlan0 in monitor mode: airmon-ng start wlan0
+===Check status and/or listing wireless interfaces ===
-To start wlan0 in monitor mode on channel 8: airmon-ng start wlan0 8
+  ~# airmon-ng
+  PHY	Interface	Driver		Chipset
+  phy0	wlan0		ath9k_htc	Atheros Communications, Inc. AR9271 802.11n
-To stop wlan0: airmon-ng stop wlan0
+===Checking for interfering processes===
+When putting a card into monitor mode, it will automatically check for interfering processes. It can also be done manually by running the following command:
+  ~# airmon-ng check
+  Found 5 processes that could cause trouble.
+  If airodump-ng, aireplay-ng or airtun-ng stops working after
+  a short period of time, you may want to kill (some of) them!
+    PID Name
+NetworkManager
+dhclient
+avahi-daemon
+avahi-daemon
+wpa_supplicant
+== Killing interfering processes==
+This command stops network managers then kill interfering processes left:
+  ~# airmon-ng check kill
+  Killing these processes:
+    PID Name
+dhclient
+wpa_supplicant
+===Turn monitor mode on===
+**Note**: It is very important to kill the network managers before putting a card in monitor mode!
+  ~# airmon-ng start wlan0
+  Found 5 processes that could cause trouble.
+  If airodump-ng, aireplay-ng or airtun-ng stops working after
+  a short period of time, you may want to kill (some of) them!

+  		(mac80211 monitor mode vif enabled for [phy0]wlan0 on [phy0]wlan0mon)
+  		(mac80211 station mode vif disabled for [phy0]wlan0)
+As you can see, it created a monitor mode interface called wlan0mon and it notified there are a few process that will interfere with the tools.
+===Turn monitor mode off===
+  ~# airmon-ng stop wlan0mon
+  PHY	Interface	Driver		Chipset
+  phy0	wlan0mon	ath9k_htc	Atheros Communications, Inc. AR9271 802.11n
+  		(mac80211 station mode vif enabled on [phy0]wlan0)
+  		(mac80211 monitor mode vif disabled for [phy0]wlan0mon)
+And you might as well want to restart the network manager via
+  service network-manager start
-To check the status: airmon-ng
