    Getting wireless to work with a BCM4312 (rev 01) wireless adapter.

    Hi, I'm new to linux, and I just installed Ubuntu on my laptop. Problem is, I can't seem to get the internet to work. I have a Broadcom Corporation BCM4312 (rev 01) wireless adapter, and I can't connect with it. I do have ndiswrapper, I just don't know what to do with it.

    Does anyone have a solution that doesn't require an existing net connection?

    There are some good instructions on the Ubuntu wiki, including what to do if you can't use a wired connection.

    I tried that, but now whenever I click on the wireless icon, it doesn't show the option to connect to a wireless network.

    Well, I installed the bcmwl-kernel-source package, and I followed the instructions for installing the BCM43xx drivers, but I can't copy an and paste my terminal because I'm on a diferent computer from the one I'm using Ubuntu on.

    ...Did I mention that I'm totally a n00b when it comes to Linux? I really don't have any idea what I'm doing...

    That's probably the issue right there; the drivers are an either/or proposition... You should install either b43/sta (wl) or b43, but not both.

    Try:

    Code:
    sudo modprobe -r b43 ssb wl
    sudo modprobe wl
    Does that work?

    When I try that, it says "FATAL: Module wl not found."

    This suggests bcmwl-kernel-source was not successfully installed.

    Put the LiveCD in your drive and go to: System, Administration, Software sources and check the box below "Installable from CDROM". Then open a term and do:

    Code:
    Code:
    sudo apt-get update
    Then:

    Code:
    Code:
    sudo apt-get install bcmwl-kernel-source
    Now reboot and select the STA driver. in System, Administration, Hardware Drivers

    Alright, that worked! I'm online now.
