I'm a bit confused and I hope you can help me...
I have ubuntu 8.0.4 and my wireless card is the one integrated in asus p5wdh deluxe (chipset rtl8187).
It seems that ubuntu sees my wireless card: if I type iwconfig I see wlan0 in mode managed.
If I try to do airmon-ng stop wlan0 and then
airmon-ng start wlan0 <my_ch>
I get an error:
wlan0 Realtek 8187L rtl8187 - [phy0]/usr/sbin/airmon-ng: 833: cannot create /sys/class/ieee80211/phy0/add_iface: Directory nonexistent
Error for wireless request "Set Mode" (8B06) :
The strange thing is that If I start kismet and then I stop it, if I retype iwconfig I see that my wlan0 is in mode monitor
I read the page hxxp://aircrack-ng.org/doku.php?id=r8187 but I don't understand if I have to install it or not.
Can someone help me?
