Recommended Posts

i have never had this problem before with backtrack before. but it seems i have to find drivers for my wireless lan card. though i dont know what type it is. all i know for sure is that it is a "Wireless-G Card with Bluetooth" is there anything i can do in backtrack to find it or will i need to open windows and look under the device manager. also were can i find drivers for backtrack, and how do you install them?

thanks in advance.

Just found the card its a broadcom 802.11b/g Wlan

you guys would be proud of me.

i did some research..........

Notes for broadcom owners

Broadcom has used some of the BCM43XX designations for more than one flavor of card. To tell for sure if your card is supported, use the command 'lspci -n| grep 14e4'.

If 14e4:XXXX is 4301, 4307, 4311, 4312, 4318, 4319, 4320, 4321 (aka 4306 802.11b/g? only), 4324, or 4325, the card is supported with b43 driver.

All others are with 4313, 4315 (4310?), 4328 (4321 802.11n dualband), 4329 (4321 802.11n 2.4GHz), 432a (4321 802.11 5GHz), 432b (4322), 432c, 432d can only use broadcom's linux_sta driver, which is similar to using ndiswrapper.

You will need kernel.lzm if you downloaded cdrom version and will need to compile this driver. You may also need compat-wireless if the driver does not work and/or search for possible answers via google. Last but not least, there is absolutely NO support whatsoever with linux_sta for monitoring/injecting. Desperate users can try and join their mailing list

which the link takes you here

http://www.broadcom.com/support/802.11/linux_sta.php

though im still going have to find something with info how do it all this stuff. i will post back when i come up with something.

I found more information here.

http://linuxwireless.org/en/users/Drivers/b43#fw-b43-lp

but im still kind of confused on what i have to do.

i know i need to do this:

You are using the b43 driver from linux-2.6.25 or newer

Follow these instructions if you are using the b43 driver from linux-2.6.25 and newer or compat-wireless-2.6, or from any current GIT tree.

Use version 012 of b43-fwcutter.

Download, extract the b43-fwcutter tarball and build it:

wget http://bu3sch.de/b43/fwcutter/b43-fwcutter-012.tar.bz2

tar xjf b43-fwcutter-012.tar.bz2

cd b43-fwcutter-012

make

cd ..

Use version 4.150.10.5 of Broadcom's proprietary driver.

Download and extract the firmware from this driver tarball:

export FIRMWARE_INSTALL_DIR="/lib/firmware"

wget http://mirror2.openwrt.org/sources/broadco...50.10.5.tar.bz2

tar xjf broadcom-wl-4.150.10.5.tar.bz2

cd broadcom-wl-4.150.10.5/driver

sudo ../../b43-fwcutter-012/b43-fwcutter -w "$FIRMWARE_INSTALL_DIR" wl_apsta_mimo.o

Note that you must adjust the FIRMWARE_INSTALL_DIR path to your distribution. The standard place where firmware is installed to is /lib/firmware. However some distributions put firmware in a different place.

but im not really sure what im doing....

or is what i have quoted above all i have to do?

i tried this and it doesnt seem to work. so once again im lost.

Go to the official BT4 site here: http://www.backtrack-linux.org/bt/wireless-drivers/ Broadcom cards are not highly supported. Maybe older cards that worked in BT2 and 3 would work if you find the drivers for them, but newer ones arent supported. Most standard drivers, only let you get online. They wont be usefull for cracking wifi since they more than likely dont do monitor mode or injection.

im still trying to do this

b43 driver for linux-2.6.24 (Ultimate Edition 1.8/Ubuntu 8.04)
If you are using the b43 driver from linux-2.6.24, follow these instructions.
Use version 011 of b43-fwcutter.
Download, extract the b43-fwcutter tarball and build it:

    Select all
    wget http://bu3sch.de/b43/fwcutter/b43-fwcutter-011.tar.bz2
    tar xjf b43-fwcutter-011.tar.bz2
    cd b43-fwcutter-011
    make
    cd ..

i can get this part done to the make. but then i get lost.

Use version 4.80.53.0 of Broadcom's proprietary driver.
Download and extract the firmware from this driver tarball:

Code: Select all
    export FIRMWARE_INSTALL_DIR="/lib/firmware"
    wget http://downloads.openwrt.org/sources/broadcom-wl-4.80.53.0.tar.bz2
    tar xjf broadcom-wl-4.80.53.0.tar.bz2
    cd broadcom-wl-4.80.53.0/kmod
    sudo ../../b43-fwcutter-011/b43-fwcutter -w "$FIRMWARE_INSTALL_DIR" wl_apsta.o


Note that you must adjust the FIRMWARE_INSTALL_DIR path to your distribution. The standard place where firmware is installed to is /lib/firmware. However some distributions put firmware in a different place.

i dont understand how the first command works.

export FIRMWARE_INSTALL_DIR

everytime i type it in i just get ">"

what is the Firmware_install_dir is that just the /lib/firmware? or is it something else.

If you can get it compiled after you do make, then run "make install" and you should be good to go.

i did the make install and still nothing.

someone said that you have to activate the driver. but i dont know how to do that with backtrack.

plus i read that with my card i will only be able to get on the internet. not do any monitoring or injecting. which makes it pointless.

but after more research this link stats that it is possible. we will see.

modprobe the card id, then ifconfig -a to see if its loaded. If this is an internal card, make sure to enable the radio too, so the card will start (usually a function key combo, like FN+2, etc)

You cannot use wireless cards unless they are USB inside of virtual machines. If you have a USB one you can use USB Pass through to accomplish this.

thanks for your quick replay..

yes i have one D-link DWA-125 usb wifi card, and i use it on VMware.

i just want to know that the internal wifi card running or not.

b'cose when you using aireplay-ng tool you need two wifi card for injection.

so now i have to buy another wifi card.

if it possible to perform aireplay-ng attack using single wifi card.

b'cause in offsec wifu training, they use two wifi card to perform this operation.

i attached the video with this post. please show it and study it....

and replay me..

thank you

unfortunate the video size is more than 3 mb. and i did'nt attached here. sorry .

if you have any mail-id, i'll send you on that.

You only need one card for injecting, not 2.

Ideally you could have two cards one for monitoring the traffic and the other for injection.
