How to check if you cards supports monitor mode

How can I check if my wireless card supports monitor mode, e.g. for use with aircrack-ng?
use command ifconfig to list all interfaces check whether it shows wlan0 or something like wlan1 etc. then enter command airmon-ng start wlan0 it will show the output monitor mode enabled on mon0 if it does not shows then your wireless card is not in monitor mode install drivers and try again or buy a usb wireless adapter the cheapest and best one is tp-link TL-WN722N it supports monitor mode just plug and play drivers are already available in kali linux am using the same one supports monitor mode good at cracking wireless password mitm attacks and the range is also good hit like and subscribe if you have any questions comment below...
