root@shubham:~# iwconfig wlan0 mode monitor
Error for wireless request "Set Mode" (8B06) :
    SET failed on device wlan0 ; Operation not supported.

Trying to change the mode of wlan0 from managed to monitor. Need some help.

Not every wireless card and driver combination support monitor mode, particularly, most Broadcoms. If the command reports, "Operation not supported," I'm afraid that's what it means: it can't do it.

You can double-check from the terminal:

iw list

Here is a sample from my machine:

Supported interface modes:
         * IBSS
         * managed
         * AP
         * AP/VLAN
         * monitor
         * P2P-client
         * P2P-GO
         * P2P-device

If your result doesn't include monitor, then it simply isn't possible.

You could, of course, get a different wireless card.


if you are looking for the solution, here is an alternative way of applying monitor mode

ifconfig wlan0 down
airmon-ng check kill
airmon-ng start wlan0

Hope this helps
