    did you scan as root?
    if you scan as a normal user it just shows the last result of the scan and since you dont have any result you will find no network
    Linux and me it's a love story

    The bcm43xx driver module requires firmware to be installed before it will work correctly. Firmware is not installed by default, so if you did not install it, it is not installed. Look at the output of this command for any errors:
    Also, the bcm43xx driver is no longer used. The b43 driver has replaced it. It is available in newer kernels. (>= 2.6.18) It may not be compiled into the earlier 2.6.18 kernels, but it is available with a re-compile.

    You did not post your distro version or kernel version. This type of info should be posted when asking for help.

    i use debian..i have kernel version 2.6.22
    the code dmesgshows no errors as far as the driver is concerned and my light is up and running!
    i usually log in as root so that might not be the problem

    thanx guys!!!it finally worked

    i finally decided to settle for ndiswrapper ..i installed it ,plus a new kernel for my debian machine the headers for this kernel.
    in the file
    put the line
    alias wlan0 ndiswrapper
    then hit the code
    which showed my interface wlan0
    finally the code
    iwlist wlan0 scanning
    gave me some metworks and now am enjoying the net in linux
    thanx guys!!!!!!

    When you use NDISwrapper, you usually need to blacklist the b43 (or bcm43xx) module to keep it from loading. If NDISwrapper and b43 are loading at the same time, your wireless will not work.

    In the file /etc/modprobe.d/blacklist add this to the bottom of the file:
    blacklist b43
    This will prevent it from automatically loading.

    Which distro are you using? Distros using the newer b43 driver instead of bcm43xx need to unload ssb before loading ndiswrapper. This becomes a problem if your ethernet driver is b44 which means you need to write a script to unload ssb, load ndiswrapper then allow ssb to load again with b44.

    We can cross that bridge when we come to it though...for now what distro are you using, and can you post the output from the following commands
    /sbin/lsmod |grep -i ssb
    /sbin/lsmod |grep -i b4
    uname -r
