[Neutron]

My wireless card finally work but i cant switch it to MONITOR MODE so i cant use airodump
Driver are probably ok because i can connect to wifi without problem.

airmon-ng

Interface	Chipset		Driver

eth1		Broadcom		wl

airmon-ng start eth1

Found 2 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
2432	wpa_supplicant
2448	dhclient

Process with PID 2432 (wpa_supplicant) is running on interface eth1



Interface	Chipset		Driver

eth1		Broadcom		wl (monitor mode enabled)

wl (monitor mode enabled) even if there is MONITOR MODE ENABLED in iwconfig is still MANAGED

airodump-ng 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.

From bunch of topics I read It's because it isn't switched to monitor mode.

I'll be glad for any help

Based on my past experience, the broadcom chipset was flaky. Sometimes it would do monitor mode, & sometimes not (don't recall the one I was using, unfortunately). Have you checked the BT wiki & the hardware compatibility list forum?

login as root and do this...
download latest compat-wireless drivers:

wget http://linuxwireless.org/download/compat-wireless-2.6/compat-wireless-2011-10-12.tar.bz2tar
tar xvf compat-wireless-2011-10-12.tar.bz2tar

cd into extracted directory then run:

make && make install

reboot and if it works
