I am unable to chage to the monitor mode in iwconfig to monitor. The error message reads.
Error for wireless request "Set Mode" (8B06):
Set failed on device eth0 ; Invalit argument.
I am using Slackware11. When I try booting into Backtract live distro, the command works fine. My card or antenna is not the issue: http://www.wlanparts.com/product/WDNL2511CDPLUSEXT2
I have the feeling it might be some package im missing. From what I read, anything in /etc/rc.d/rc.wireless.conf would not cause the problem.
Any help would be much appriciated.
