Hey guys, I haven't been here in awhile since my last failed attempt, but since the release of BT4, I felt the need to give it a new try. I have finally got the notorious linux broadcom drivers up and running. The only issue i have now is when i try to run airodump:

root@bt:~# airodump-ng --ivs -w dmp eth1
ioctl(SIOCSIWMODE) failed: Invalid argument

ARP linktype is set to 1 (Ethernet) - expected ARPHRD_IEEE80211,
ARPHRD_IEEE80211_FULL or ARPHRD_IEEE80211_PRISM instead.  Make
sure RFMON is enabled: run 'airmon-ng start eth1 <#>'
Sysfs injection support was not found either.
but when i do run airmon-ng i get:

root@bt:~# airmon-ng start eth1

Found 4 processes that could cause trouble.
If airodump-ng, aireplay-ng or airtun-ng stops working after
a short period of time, you may want to kill (some of) them!
PID     Name
6369    knetworkmanager
6481    NetworkManager
6486    wpa_supplicant
7225    dhclient
Process with PID 7225 (dhclient) is running on interface eth1

Interface       Chipset         Driver

eth1            Unknown                 wl (monitor mode enabled)
I would cry if i finally got this to work, and I feel like i'm so close. Any help is appreciated.
Thanks in advance
