Hi all!

Having just posted opened a thread about this on the FreeBSD forum, I'll more or less copy/paste that post in this mail. Thread: http://forums.freebsd.org/showthread.php?p=227470

I have the "Alfa AWUS036h 802.11 b/g Long-Range USB Adapter" connected to my laptop which is running a FreeBSD 8.1 installation. The adapter is widely used for injecting wireless frames, which is my objective as well.

I have set it up to use the urtw(4) driver (manpage) by loading the module at boot time.

The output of `dmesg | grep urtw` is as follows:

urtw0: <vendor 0x0bda product 0x8187, class 0/0, rev 2.00/1.00, addr 2> on usbus7
urtw0: unknown RTL8187L type: 0x8000000
urtw0: rtl8187l rf rtl8225u hwrev none


That looks kinda strange, but the adapter works and I am able to successfully create a wlan0 interface and connect to my WPA2 secured network.
However, if I want to create a wlan0 interface (after destroying the previous one) that is usable for packet injection, this is what I get.

`ifconfig wlan create wlandev urtw0 wlanmode ahdemo`

urtw0: AHDEMO mode not supported # <-- this line is colored white as opposed to normal gray
ifconfig: SIOCIFCREATE2: Operation not supported


Is this mode simply not (yet) supported?


Cheers,

Mark / asfdg
