    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
    Code:
    start-network
    Code:
     sudo wicd start
    Try all of the above or all three.
    Start Wicd manger from KDE

    5. check by
    Code:
     iwconfig
    whether wlan0 is up.Also try
    Code:
    iwconfig wlan0 up
    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

    ----------------------------------------------
    Dealing Broadcom ( Credits : stormeye)

    Now this is 1 card which will give you nightmares with all Linux installations.

    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 !

    are you using backtrack 5 ? if not then i would advise you to install it first as it ships with improved wifi drivers list.
