    Question wireless on Dell Latitude D800

    Hello all!

    New installation of Ubuntu 8.04 on a Dell Latitude D800. Installation went smoothly but now I can't get the wireless to connect to my router. It connected 45 minutes ago while I was running Windows XP, but now I've wiped Windows off my computer (intentially)

    Here's the output from my terminal:

    Any help would be appreciated.

    Thanks in advance!

    You could try the firmware first. Your card might be recognized in System->Administration->Hardware Drivers. Just enable the Broadcom card. If it is not there, open up the Terminal and type:
    Code:
    sudo apt-get install b43-fwcutter
    It will ask you if you want to have it find the firmware for you. Just say yes and it will install it for you.

    Thanks so much for the quick reply. Here's the error message I got after running the code you said to run:

    $ sudo apt-get install b43-fwcutter
    Reading package lists... Done
    Building dependency tree
    Reading state information... Done
    E: Couldn't find package b43-fwcutter
    Thoughts?

    Thanks again for your help - I hate to be such a pain.

    I am guessing that you have a working internet connection right now in Ubuntu. If that is the case, have you ran any updates? If not, please type:
    Code:
    sudo apt-get update
    and it should update from the repositories. Once it does that, you should be able to install it.

    Cheers to you, Ayuthia. The update followed by your initial magic code did the trick.

    Thanks!

    BTW, where can I find a useful wiki/document that describes exactly what all these words (sudo, apt-get, fwcutter) mean?

    Thanks again, especially for being so prompt so late at night.

    Heres the wiki page on Sudo and root: https://wiki.ubuntu.com/RootSudo
    This explains aptitude/apt-get and the repositories: https://wiki.ubuntu.com/AddingRepositoriesHowto

    The fwcutter stands for firmware cutter. The Linux Broadcom drivers need a portion of the firmware to make it work so that is why it is called fwcutter.

    By the way, you don't necessarily need to use apt-get. You can also use Synaptic. I tend to use the Terminal a lot...

    And how is it that you get updates if you can't connect to internet?
