    I need help with connecting to a wireless network.

    Hello. I have recently installed Ubuntu 12.1 on my dell latitude d630 and it is running with windows. When I boot windows, it immediately connects to my wifi, but when I boot Ubuntu and click the wireless networks button on the menu at the top, there are no networks on which I can connect. Please help.

    I assume you are using the default connection manager? What brand is the wireless network card in question? Perhaps there is a restricted propriety driver which has not been enabled yet. Check the additional drivers. (Dash > search drivers, select additional drivers) Lol is your wireless turned on? (I tried to diagnose this same thing once and realized for some reason my wireless key just needed to be pressed after a fresh install)

    If you are still having problems open a terminal and type iwconfig and rfkill list all
    Post the results of these.

    Re: I need help with connecting to a wireless network.

    I must apologize, but I don't know about half the things you said. How do I turn on my wireless key? Also, after typing iwconfig it gave me this
    Eth0 no wireless extensions.
    Lo no wireless extensions.
    When I typed rfkill it gave me
    Usage: rfkill [options] command
    Options:
    --version. Show version (0.4-1ubuntu3 (Ubuntu) )
    Commands:
    Help
    Event
    List [identifier]
    Block identifier
    Unblock identifier
    Where identifier is the index no. of an rfkill switch or one of:

    My apologies, it was an error on my behalf as well. The rfkill one needed a list all after it, I made it sound like I was telling you to list all.

    Code:
    rfkill list all
    It seems to me that you have no drivers installed for your card, or the card is not being detected.


    Here is what I think will get you going after much research on this:

    Open terminal type

    Code:
    sudo apt-get autoremove bcmwl-kernel-source
    then type

    Code:
    sudo apt-get install firmware-b43-installer
    Though you will need an internet connection for this, do you have an ethernet cable by any chance?

    I do not have any drivers installed on Ubuntu. Also, the only way I can connect to the internet is wirelessly, thus i have to download any drivers from windows XP. I have been to other sites to donwnload the correct drivers and then had to save them to a flashdrive as well as any instructions I could find. The instructions I did find I could not understand.

    Ack! These crazy broadcom drivers.

    First on a computer with internet;

    Go here and download Quantal Quetzal release:

    Code:
    https://launchpad.net/ubuntu/+source/b43-fwcutter
    Download this next

    Put that onto your flash drive
    Boot ubuntu and insert your flash drive. Copy the downloaded files to your home folder.

    Enter this into a terminal to install b43-fwcutter:
    Code:
    sudo dpkg -i b43-fwcutter
    Then type this to install firmware driver for your wireless card:
    Code:
    tar xfvj broadcom-wl-5.10.56.27.3_mipsel.tar.bz2
    then

    Code:
    sudo b43-fwcutter -w /lib/firmware broadcom-wl-5.10.56.27.3/driver/wl_apsta/wl_prebuilt.o
    Restart your computer

    Open terminal and paste

    Code:
    sudo modprobe b43
    In theory this will do it. I am quite confident in this.

    If not refer to https://help.ubuntu.com/community/Wi...Driver/bcm43xx

    Near the bottom of the page; b43 No Internet Access
    Feel free to get back to me if you get terminal errors.

    This was my error when entering the first code:
    dpkg: error processing b43-fwcutter (--install):
    cannot access archive: No such file or directory
    Errors were encountered while processing:
    b43-fwcutter

    Ok, after some more searching, and brain taxing download this:

    https://launchpad.net/debian/sid/+so...5.orig.tar.bz2

    Move file to home, than right click the file and select extract.

    In terminal type
    Code:
    cd /home/tombstone/b43-fwcutter-015
    (Replace tombstone with your user name)
    Then type:
    sudo make
    Then
    sudo make install

    This WILL install fwcutter, ah progress.

    Next move the file broadcom-wl-5.10.56.27.3_mipsel.tar.bz2 (download at " http://mirror2.openwrt.org/sources/b...mipsel.tar.bz2 ") to your home folder.

    In terminal type:

    Code:
    tar xfvj broadcom-wl-5.10.56.27.3_mipsel.tar.bz2
    then
    Code:
    sudo b43-fwcutter -w /lib/firmware broadcom-wl-5.10.56.27.3/driver/wl_apsta/wl_prebuilt.o
    Restart your computer, then terminal
    Code:
    sudo modprobe b43
    Hopefully after all this you will have internet! (I'm 95% sure you will)
