    Yes! It works! using this guide I have now got backtrack 4 working with injection

    So I will write up my experience to hopefully help other people that are in the same position.
    I have a dell mini 10v.

    to install the kernel I used this guide: http://www.jwgoerlich.us/blogengine/...2/default.aspx
    But obvikously just follow it for the kernel bit.

    then for the cmwl-kernel-sources bit, this didn't work so i down;loaded bcmwl-kernel-source_5.10.91.9+bdcom-0ubuntu4_i386.deb (if you google it, you should be able to get a download for it pretty easily. But when I did "dpgk -i bcmwl-kernel-source_5.10.91.9+bdcom-0ubuntu4_i386.deb" IT came up with an error. So i then had to use this guide http://ubuntuforums.org/showthread.php?t=1355905 to get it to work properly to install.

    I know have to modprobe -r wl and modprobe b43 at every start, but I will write a script to do it.

    Kismet works, aireplay works, so I am guessing the rest will work too!

    Thanks greatly for everyones help

    Seems like Lucid is the magic here . To make the commands automatically run, add this to "/etc/rc.local"

    Code:
    modprobe -r wl
    sleep 3               #Wait 3 Seconds
    modprobe b43

    Funny tho, I've been using those commands in my rc.local file until recently (yesterday actually) has lucid was crashing just after the login screen when booting. Removing the commands and booting normally did it and now, I'm using latest lucid with latest kernel and compat-wireless. Injection works and I don't have issues at all, except the one where sometimes, it won't boot past the grub window (just restart the computer and eventually, it'll work)

    Can you post a guide on the first page for working injection/monitor mode and no dma errors in ubuntu? I tried this on pio mode but no success. Also, which version of ubuntu and kernel should I use?

    Thanks

    DarkAngel88: The newest Lucid kernel screwed me in the same way .

    dalga999: PIO mode has never worked. The b43 driver originally worked on the Ubuntu 10.04 Lucid Beta 2 kernel, but doesn't work after updates.

    Off topic: These waves of working and not working make me think of y=cos(x)+1/2. I guess I've been doing too much pre-calc homework.

    Installed the latest daily kubuntu last night... i must say that it is running GREAT!! Now for the reason we are here....

    Installed Kubuntu lucid lynx daily

    Connected via wired eth0

    Installed all updates

    Installed bcmwl-kernel-source

    removed network-manager, knetworkmanager and installed wicd (seems to work better)

    changed interface to wlan0 for wicd

    added "ifconfig eth1 up" to rc.local (just to be on the safe side, for b43 use later)

    created a script to load b43 after boot

    Code:
    #!/bin/sh
    sudo rmmod wl
    sudo sleep 4
    sudo modprobe b43
    sudo sleep 4
    sudo ifconfig wlan0 up
    reboot

    copy or cut firmware from broadcoms sta drivers

    run script

    YAY!! working b43 open source drivers

    rlelliott: Nice ! Hopefully it will continue to work in the final Ubuntu 10.04 release.

    I have a Dell Mini 9 and after I updated kernel in Karmic, my fully working b43 stopped working. I then put in Lucid beta 2 instead. This didn't work either. Not with the 2.6.32-19 or the 2.6.32-21 which was installed in an update. I then tried 2.6.33 as suggested here but without any luck.

    2.6.34-rc5-lucid fixed all my problems.

    I used the guide here to upgrade kernel:

    http://www.ramoonus.nl/2010/02/25/

    But of course used the 2.6.34-rc5-lucid from:

    http://kernel.ubuntu.com/~kernel-ppa....34-rc5-lucid/

    tempoAccount: Welcome to Ubuntu Forums ! And cool! I didn't know the development version of kernel 2.6.34 is out already.
