    Question Broadcom 802.11b/g WLAN issues on Maverick

    Howdy all

    I'm really new to all of this, so, if you guys have any suggestions on what other info I should give you, I would (and I think yo would too) appreciate it.
    I've installed Ubuntu 10.10 a week ago in my Acer Aspire 3680, and I immediately fell in love with it. The only really big/unsolvable problem I've come up with was the gorram wireless card, that wouldn't work at all. I've roamed the web a bit and found two possible solutions to my problem: NDIS Wrapped and MADWiFi.
    At first I tried MADWiFi, mainly because a friend recommended it, but I couldn't find a way of making it work on Maverick (50% of tutorials found were about Ubuntu 8 and 9, that wouldn't work, and the other 50% had broken links when I got to the "wget" part ).
    I proceeded to try NDIS Wrapped, but almost immediately I faced yet another problem: I had absolute no idea what .inf file I should have (and as I completely erased Windows from my HDD, I had no access to my old drivers), yet reaching another dead-end.
    So, I ask you, o mighty forumers, help this poor noob access wireless internet!


    For your information, I have an Acer Aspire 3680-2992 notebook, with an Intel Celeron M processor 440, and the Mobile Intel 940 GML Express chipset. I've got a 512MB RAM, but it's a DDR2, so I plan changing it soon. Any other information you need, just give a shout (and if possible, inform me where I can find that information, because I'm a total zero at this) and I will reply as soon as possible.

    Thank you! (Long thread, wasn't it?)

    Code:
    sudo apt-get install bcm43xx-fwcutter
    and if that doesn't work, heres the inf files

    The first step would be to see which wireless card is in your laptop and then check for which drivers apply.According to your laptop specs it should be an Atheros wireless which wont work with a Broadcom(bcm43xx) driver.

    But.....you need to be connected to the net. So, if you can't hardwire a connection to your router, then do the following:

    - after ubuntu is booted, load up the LiveCD (or USB flash drive if you went that route to install)

    - using "Places", navigate to the /pool/main/b folder and you'll see the folder for the firmware cutter. Navigate to that folder and double-click on the file to begin installation. It will ask for a password - use your normal password, it just won't show on the screen.


    We all need to remember that there are a lot of people who do not have access to a hardwire connection, so without wireless working they can't do things like sudo apt-get. For these types of instances, the firmware cutter, ndiswrapper and ndisgtk (the GUI'd front-end to ndiswrapper -> use it, you'll be glad you did!) are all included on the LiveCD.

    - firmware cutter in /pool/main/b

    - ndiswrapper and ndisgtk in /pool/main/n (remember to install ndiswrapper common, then ndiswrapper utilities and then ndisgtk). Ndisgtk is accessed via System/Administration/Windows Wireless Drivers and takes the place of trying to enter tons of stuff into the command line.

    Also keep in mind - there are a lot of posts out there that are outdated now. There is no need to download the ndiswrapper source and compile it as some old post recommend. Use ndisgtk instead of typing in a bunch of ndiswrapper commands, modprobe's, etc. in the command line, and remember that the old blacklist file, /etc/modprobe.d/blacklist, was renamed to /etc/modprobe.d/blacklist.conf quite a while ago. Old posts still make reference to either editing or echoing lines in the old blacklist file, and this will no longer work.

    The inf file did the trick, but only until I turned my notebook off, when I tuned it on again it wouldn't locate the wireless connection again. Any clues on what to do?

    I'm going to assume you used ndiswrapper manually, that being typing things in at the command line. What you probably didn't do was add it to the modules file so it is loaded at boot:

    sudo gedit /etc/modules

    add a line to the end that simply says:

    ndiswrapper

    save the file and exit

    reboot

    Please, for future reference, and for others who might be following this thread looking for help, install ndisgtk when you install ndiswrapper (both can be installed from the LiveCD in /pool/main/n/ndiswrapper and /pool/main/n/ndisgtk). Ndisgtk is a GUI'd front end to ndiswrapper and takes away all of the command line typing and things like editing the modules file. You simply start up ndisgtk via System/Administration/Windows Wireless Drivers, click on "new" and point it to the .inf file for your driver files. That's it - it does the rest.

    Okay, now you got me worried: I didn't type anything in the command line, I went to the "Windows Wireless Drivers" tab that appeared after I downloaded NDIS Wrapper through the Ubuntu Software thingo.

    Hummmmmm.....that would have done it all for you. Please log in to a terminal session and check the /var/log/Xorg-0.log (I *think* that's what it's called). See if there are error message in there, and if so, post them back here.

    Also, while in the terminal session, type:

    cat /etc/modules <press enter>

    see if ndiswrapper is in that list - if not:

    sudo echo ndiswrapper/n >> /etc/modules

    then reboot.

    EDIT: Also try sudo modprobe ndiswrapper then wait a couple of minutes and see if wireless is working.

    Would also like to see the output of cat /etc/modprobe.d/blacklist.conf

    Ok, cat /etc/modprobe.d/blacklist.conf brought this:
    Code:
    # This file lists those modules which we don't want to be loaded by
    # alias expansion, usually so some other driver will be loaded for the
    # device instead.

    blacklist evbug

    # low-quality, just noise when being used for sound playback, causes
    # hangs at desktop session start (Ubuntu: #246969)
    blacklist snd_pcsp
    
    # ugly and loud noise, getting on everyone's nerves; this should be done by a

    blacklist pcspkr
    
    # EDAC driver for amd76x clashes with the agp driver preventing the aperture
    # from being initialised (Ubuntu: #297750). Blacklist so that the driver

    # really needed.
    blacklist amd76x_edac
    Couldn't find the /var/log/Xorg-0.log thing though.

    When I typed sudo modprobe ndiswrapper, this message showed up:

    WARNING: All config files need .conf: /etc/modprobe.d/blacklist, it will be ignored in a future release.

    Is it important?
