BCM4312 802.11b/g [14e4:4315] (rev 01) wireless card works, but cannot switch to monitoring mode - want to use aircrack

Hi,

Please first connect your network card to the wireless router using an ethernet cable (also known as a LAN cable).

In order to gather essential troubleshooting information about your wireless card, please follow this procedure:

Step 1: Open Terminal from "Applications->Accessories->
Terminal"

Step 2: Run the following commands (copy-paste each line below to the Terminal then hit <enter> after each line)

sudo iwlist scanning
sudo lshw -C network
lspci -nn
lsusb
uname -a
dmesg | grep ound
dmesg | grep witch
iwconfig

Step 3: Please post results (copy/paste terminal output from each command) on this thread

Step 4: Please also provide us with the exact model and make of pc that you are using

Keep in mind that one or more of the following 4 basic components need to be configured correctly so that wireless can work correctly in Linux:

Wireless configuration in the BIOS, hardware wireless switch setting, active wireless driver version, and firmware for the wireless chipset (stored as a file in Linux).

Regards,

Mark

I'm using a Dell inspirion 1425 running Ubuntu 9.04 64bit. if I use the the driver ubuntu found, Boardcom STA, the wireless works, but I can't turn my wireless to monitor mode. I've been trying to learn aircrack on and off for a year now, so I hope i can actually get this done.

argh! well that's very annoying. I've been trying so long and I don't even have the right card... *sigh*

Tell me about it... if I had known this laptop had this wifi chipset, I wouldn't have bought it... my wife says I'm nuts :)
