    Please detach the ethernet cable and then reboot so we have a clean slate. Try to connect with wireless. Now we're going to see what Network Manager is doing all this time. We're going to pipe the terminal output into a text document so you can reconnect the ethernet and not have the output corrupted with ethernet rather than wireless.
    Code:
    sudo cat /var/log/syslog | grep -e ethernet -e b43 | tail -n20 > jdavis.txt
    Now hook up the ethernet and go into your user directory and find the file jdavis.txt and copy and paste the entire thing here. Thanks.

    Re: Wireless Trouble; Firmware Missing

    Looks remarkably perfect. That's my favorite kind of problem. It looks perfect except it doesn't work! I wonder what network Manager is doing all this time. Please detach the ethernet cable, try to connect with wireless and run:
    Code:
    sudo cat /var/log/syslog | grep -i network | tail -n20
    Please post the result here.

    Re: Wireless Trouble; Firmware Missing

    I followed this path to get wireless working.

    Ubuntu software centre-firmware b43 installer(might be in "system" sub menu)- install-restart-make sure "wireless" switch is on. (My older HP has a separate switch to turn on wireless) Upon rebooting Ubunto notified me that a wireless network was available . Go to system settings and open network. choose the wireless network you want to connect to.

    Re: Wireless Trouble; Firmware Missing

    Hi all.

    I got it working by doing the steps below at the end.

    Before you follow my steps, I strongly advise you to... be sure of what you are doing, and check posts which might criticize mine.

    I am a beginner in the ubuntu stuff..and what my one year ubuntu experience has taught me is:

    BE CAREFUL WHEN TYPING SUDO COMMANDS POSTED AROUND! sh*t can happens if you dont really know what you re doing.

    By typing the lines below I had a very slight idea of what I wasdoing...but it worked b4 so I decided to try once again.

    I have a hp pavillion with a broadcom 802.1 (I guess thats the name of the thing) network adapter. When I first installed ubuntu 11.04 these were the following commands:

    sudo apt-get purge bcml-kernel-source > ( apparently ubuntu installed smth in kernel that prevented the wireless from working and it had to be removed. This was not necessary in 12.04)
    sudo apt-get install firmware-b43-installer
    sudo apt-get install b43-fwcutter (this was not necessary either at 12.04)

    then restart networking services:

    sudo /etc/init.d/networking restart

    emphasizing chili555's advice:
    other usefull wireless commands
    http://ubuntuforums.org/showthread.php?p=6183681

    that did it. hope it helps and once again: BE CAREFUL
