-==== mac80211 drivers monitor mode ==== 
- 
-See [[install_drivers#mac80211_versus_ieee80211_stacks|mac80211 versus ieee80211 stacks]] for some background information. 
- 
-When using the mac80211 version of a driver, the use of airmon-ng and the aircrack-ng tools are slightly different. 
- 
-Running: 
- 
-   airmon-ng start wlan0 
- 
-Gives something like: 
- 
-   Interface   Chipset      Driver 
-    
-   wlan0      Intel 4965 a/b/g/  iwl4965 - [phy0] 
-            (monitor mode enabled on mon0) 
- 
-Notice that it created "mon0" You must then use "mon0" in all the subsequent aircrack-ng tools as the injection interface. 
- 
-To remove monitor mode enter: 
- 
-   airmon-ng stop mon0

 To determine the current channel, enter "iwlist <interface name> channel" If you will be working with a specific access point, then the current channel of the card should match that of the AP.  In this case, it is a good idea to include the channel number when running the initial airmon-ng command. To determine the current channel, enter "iwlist <interface name> channel" If you will be working with a specific access point, then the current channel of the card should match that of the AP.  In this case, it is a good idea to include the channel number when running the initial airmon-ng command.

 +==== Debugging issues ====
 +
 +airmon-ng has two options to show more information, which can be useful when reporting or debugging issues.
 +
 +=== --verbose flag ===
 +
 +It gives information about the system as well as details about the wireless card.
 +
 +  root@kali:~# airmon-ng --verbose
 +  
 +  No LSB modules are available.
 +  Distributor ID: Kali
 +  Description: Kali GNU/Linux Rolling
 +  Release: 2019.1
 +  Codename: n/a
 +  
 +  Linux kali 4.19.0-kali4-amd64 #1 SMP Debian 4.19.28-2kali1 (2019-03-18) x86_64 GNU/Linux
 +  Detected VM using lspci
 +  This appears to be a VMware Virtual Machine
 +  If your system supports VT-d, it may be possible to use PCI devices
 +  If your system does not support VT-d, you can only use USB wifi cards
 +  
 +  K indicates driver is from 4.19.0-kali4-amd64
 +  V indicates driver comes directly from the vendor, almost certainly a bad thing
 +  S indicates driver comes from the staging tree, these drivers are meant for reference not actual use, BEWARE
 +  ? indicates we do not know where the driver comes from... report this

 +  
 +  K[phy1]wlan0 ath9k_htc[mac80211]-1.4 Qualcomm Atheros Communications AR9271 802.11n mode managed
 +
 +In this case, the following additional information can be seen:
 +  - Detailed information about the Linux distribution as well as kernel version
 +  - System is a virtual machine (and detailed information about supported features)
 +  - Detailed driver information (kernel, vendor driver, staging or unknown source), wireless stack, current operating mode and firmware version
 +
 +=== --debug flag ===
 +
 +It  will give the same information as verbose and add more details:

 +  root@kali:~# airmon-ng --debug
