When starting wlan0 in a monitor mode using airmon-ng
HTML Code:
root@kali:~# airmon-ng start wlan0

Failed to set wlan0mon up using ip
(mac80211 monitor mode vif enabled for [phy0]wlan0 on [phy0]wlan0mon)

When using airodump-ng the wlan0 Fails
HTML Code:

Then Stopped the airmon-ng

When checked the status wlan0 using ifconfig, wlan0 dint shown up.

When tried to bring wlan0 UP, it got failed and message is the same as airodump-ng .
