I noticed that the STA driver can't work in monitor mode so I disabled it. I am now using brcmsmac dirver.

Here is the output from lshw for this wireless card:

   description: Wireless interface
   product: BCM4313 802.11b/g/n Wireless LAN Controller
   vendor: Broadcom Corporation
   physical id: 0
   bus info: pci@0000:12:00.0
   logical name: wlan0
   version: 01
   serial: 70:f1:a1:71:b2:6f
   width: 64 bits
   clock: 33MHz
   capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless
   configuration: broadcast=yes driver=brcmsmac driverversion=3.2.0-24-generic firmware=N/A ip=192.168.5.185 latency=0 link=yes multicast=yes wireless=IEEE 802.11bgn
   resources: irq:17 memory:fbd00000-fbd03fff

I stop the network-manager and avahi-daemon and try to start it in monitor mode and mon0 is created.

The problem is that airodump-ng never catches anything on all channels. Do I need a new card to work in monitor mode ?

Thanks.

I have the same card and works great. I dont know where u live but u should get some air traffic. The problem with this broadcom wifi is that it is not a powerful. So try it outside, go to other places and try to get some :)

disconnect from wifi

sudo ifconfig wlan0 down

sudo macchanger -r wlan0 if u have macchanger

sudo ifconfig wlan0 up
sudo airmon-ng start wlan0
sudo airodump-ng mon0

It doesn't get any traffic even from wireless access points 2 meters away –  thelinuxer May 28 '12 at 21:20

I do ifdown on the interface then "airmon-ng start wlan0" to start monitoring. Can you please tell me which driver are you using ? –  thelinuxer May 29 '12 at 12:32
