Backtrack 4 and Wifi setup for beginners
Well a lot of my time was wasted in handling wifi in Backtrack 4 on my laptop ..
well there were reasons and hence I just want to put some points which would certainly ease the process for 1st timers if things get confusing.
1. Enter the command in console before doing anything else
Code:
/etc/init.d/networking start
2. Watch the interfaces getting load .. eth0 , l0 , etc etc .. If it gives "wlan0 found" (or similar <w...> interface),work is going to be easy then.
3. Next step is to know the wireless card you have in your laptop.
Code:
lspci | grep Network
if broadcom card .. maybe then tough road ahead :(
4. Now
Code:
/etc/init.d/wicd start
Try all of the above or all three.
Start Wicd manger from KDE
5. check by whether wlan0 is up.Also try to bring it in iwconfig.
6. Still no sign of wlan0.Try jockey-gtk b43 driver.Scroll down.
7. Still no sign of wlan0 ? have a fair peek at http://linuxwireless.org/en/users/Drivers/
and http://www.backtrack-linux.org/wiki/...reless_Drivers and find about supported driver installations and mode of operations.Just keep reading :mad:

Dealing Broadcom ( Credits : stormeye)
Now this is 1 card which will give you nightmares with all Linux installations.:mad:
Anyways 1st try jockey-gt
Log into BackTrack as root and run these commands:
Code:
/etc/init.d/networking start
apt-get install jockey-gtk
jockey-gtk
Then follow the instructions on the program that starts.Still problems ? try manually..
Downloading drivers manually >>
Go to: Broadcom.com - 802.11 Linux STA driver
And download the tarball for your system (32 or 64).
Run the following in the terminal:
Code:
/etc/init.d/networking start
tar xzf nameoffile.tar.gz
cd thefolderyouget
make clean
make
Now let's check if you have any conflicting drivers (you shouldn't, they doesn't come with BT.)
Code:
lsmod | grep "b43\|ssb\|wl"
If any of these are installed, remove them:
rmmod b43
rmmod ssb
rmmod wl
Then let's insmod the driver:
Code:
modprobe lib80211
insmod wl.ko
Note: You maybe have to start network through the KDE "start menu" before you get the WICD manager up, then you should see networks.
----------------------------------------------
some more pointers >>
Code:
lspci -vnn | grep 14e4
gives you Broadcom BCM4312 .. then well update your kernel to 2.6.33.Then also I think packet injection for wifi attacks won't work.It works partially only.

Let us see ..maybe Backtrack 5 has more to offer in handling wifi experience.It is coming out on May 10th, 2011 !
