    EDIT: I tried plugging it right into the router previously, thinking it would work, but to no avail. I'll try it here though in a second. She's playing Nibbles...
    Can you see if it will work without the sudo?
    Code:
    lshw -C network
    It will tell you that you need to be super user, but that is ok.

    EDIT:
    Can you also post your uname -a info? It will tell us what you are using.

    It worked without the "sudo" prefix.

    Okay... since that's the case, I would suggest you follow this How To:

    You can try the b43 driver first. It is the easiest to install. Here is a link on how to get installed:

    You can try this one also, it has more steps and you will need to add the b44 fix to ndiswrapper also since you do have the Broadcom wired card that uses the b44 driver.

    I would recommend going with the b43 option first. I have the same card and it works with with either option.

    Yes, good call. It's always good to have options.

    Sweet. It worked. Thanks a ton, and thanks to everyone else who helped too.

    I do have a couple smaller questions though...One for safety's sake:

    - I've read that restarting will cancel out all these settings. Is this true? If so, how do I stop that from happening?

    And one for my own curiosity:

    - What does the "sudo" prefix mean or do?

    Thanks you guys/girls. You have made me a very happy camper.

    Restarting should not cancel out these changes. The b43 driver is part of the Ubuntu kernel so the driver will boot every time. It just needed a portion of the proprietary firmware to make it work. The b43-fwcutter installed the missing firmware so now it will be able to run.

    The NDISwrapper option is the one that needs to have additional work to make it start up the next time. You have to blacklist the b43 driver and make sure that NDISwrapper is in /etc/modules so that it will load up the next time.

    This is the reason why I recommended the b43 option first. It is not that I like or dislike NDISwrapper. It just has extra steps that need some extra knowledge to help make it install easier.

    EDIT:
    I forgot to answer the second portion of your post. sudo is used to provide super-user privileges. What this means is that it places you in administrator mode and allows you to make changes to files that could affect your system.
