 +==== 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 informatio 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: ​

 Quite often, the standard scripts on a linux distribution will setup ath0 and or additional athX interfaces. ​ These must all be removed first per the instructions above. ​ Another problem is that the script set fields such as essid, nickname and encryptions. ​ Be sure these are all cleared. Quite often, the standard scripts on a linux distribution will setup ath0 and or additional athX interfaces. ​ These must all be removed first per the instructions above. ​ Another problem is that the script set fields such as essid, nickname and encryptions. ​ Be sure these are all cleared.
