Re: Monitor mode in intel 4965

Dear all,

It seems now is working. Now I understand that you can only set the card in=
 monitor when the interface is down, so the sequence of steps are:

1- disable the wlan0 interface: "ifconfig wlan0 down"
2- set wlan0 in monitor mode: "iwconfig wlan0 mode monitor"
3- enable the interface again: "ifconfig wlan0 up"
4- launch wireshark and you can capture L2 Wi-Fi packets at wlan0 :)

Thanks to all!

Daniel
