    Backtrack 2 Wireless Problems


    i just received an inspiron 1721 laptop, and I want to use it as a desktop replacement, and make my old computer a linux machine. However, I would like to use a linux live cd (in case I get somewhat nostalgic) and I decided to use backtrack 2.

    However, when I tried to hook up my wireless connection, it doesn't detect my network adapter. I receive eth0 and lo, but both are described as being without wireless connection.

    I have been really annoyed by this problem, if anyone knows what the problem is or how to fix it, please reply.

    Hi.

    We cannot help you unless we know what wireless device you have. Open konsole and do:
    Code:
    /sbin/lspci
    Then:
    Code:
    /sbin/lspci -n
    Copy the output, write it in kedit, save and name it, transfer the file to an external usb device or even floppy, boot to Windows and paste the output here.

    The chipset is broadcom 802.11n. I found a thread where someone got this card working for them with ndiswrapper. In short, you must install ndiswrapper, install the XP windows driver, blacklist the bcm43xx driver so it doesn't get loaded for your device, load ndiswrapper and it should work, according to this thread...

    I've actually got my Broadcom-based wireless card working with the native Linux driver. The only think you need is the bcm43xx-fwcutter tool. Ndiswrapper works a lot better, but also requires more tweaking (the range when using the native driver sucks).
