    Default Strange wifi problem with BT3/BT4 using usb

    hey there.
    when i use a live BT3 cd the wlan0 works okay (intel 9345) - i just enable it:
    ifconfig wlan0 up.

    but when i try using this command in BT3 usb or BT4 usb it throws an error:
    SIOCSIFFLAGS: No such device

    when i check iwconfig it shows the device.
    what is the problem here? what am i missing?

    note: the live bt3 cd that works okay has the bt3 final iso, the disk on key
    with bt3 has the bt3 usb iso, and the disk on key with bt4 has the beta bt4
    usb iso.

    had figured the solution. when you boot from the usb, the kernel disables
    the wifi. if someone comes across this just enable the wifi even if there is no led indication to it (press the wifi button on your laptop) then:

    ifconfig wlan0 down
    ifconfig wlan0 up.

    Most people that use linux know that, but it is good you found this out on your own. You don't need the down option, only up.

    yep, i'm a 2 month newbie to linux. i'm finding out that the best way to
    learn linux is to stick to the basics - i'm reading ebooks like a freak and
    i implement everything using backtrack.

    Seems like a contradiction in terms "sticking to the basics" and using BT4 at the same time. Not saying it can't be done but it might not be the best way.
    Just keep away from the "kewl tools" and you will learn the said basics far better and faster.
    Good luck.
    To be successful here you should read all of the following.

    Failure to do so will probably get your threads deleted or worse.

    your right. i wouldn't choose BT to be my first distribution to study linux but
    in the real world i'm a programmer and i was asked to pick it up on network
    security.

    thanks for the tip!
