Backtrack 3 and WLAN card from Broadcom

[bogue]

I have a WLAN card from Broadcom for 802.11b/g
I downloaded Backtrack 3 for USB Stick and it works.
But I can't find any networks with WLAN.
If I want to start with KWLAN Manager WPA Supplicant it fails.
I think there is something to do to make it work, but what.
I already tried to install this driver:
//linuxwireless.org/en/users/Drivers/b43#fw-b43-new

but it isn't working too
What did I wrong?
(The commands of the link above I copied so I usually couldn't write them wrong)

there are multiple variants of broadcom chip & which one you are having.find the chip ID of your broadcom chip using
lspci -nn
and paste the respective lines here mentioning chipset ID.
also on the same page of b43 drivers there is mentioned the compatibility.check with that.

is that the id?
BCM4311
I already used the driver for opensuse on this pc and it worked without problems.
Maybe I made a mistake by the command, because there was nothing written of a command for Backtrack.

Forgot to mention those drivers wont work with BT3 default supplied kernel.you need to upgrade kernel to 2.6.25 or above.most sophisticated alternative is to download the BT4.

Ok
If I download the BackTrack 4 it will work if I install the named driver?
That I will do

Drivers are already there in BT4.check this out.it will help you to guide further.

is there no usb version of bt4?

Now I have downloaded BackTrack 4 and it starts, but the same problem again.
Even LAN is not working.
I don't understand it.
In dmesg is now writen driver loaded or something like this.

/etc/init.d/networking start
/etc/init.d./NetworkManager

Thanks!
It finds my network and I can connect.

Now I have read a bit about aircrack-ng.
Ok Kismet is for collecting packets am I right?
I started kismet and it collected packets from my WLAN, but where can I find this packets to use them in aircrack?
are that the files in /var/log/kismet?

And packets collecting only helps if I have WEP or?
Is there any danger, if I try to bruteforce my own WLAN?
For BruteForcing in aircrack I need a dictionary is there no function to bruteforce without dictionary just trying out passwords?
I know it lasts long, but I will cut down my password to 5 letters.
