    If you face the same issues and same errors on the fresh install as before, check your installation media for consistency : https://help.ubuntu.com/community/HowToMD5SUM

    If errors are found, it means your downloaded ISO of Lubuntu is broken itself, in which case, a fresh download would be essential. For downloading ISOs, torrents are recommended to ensure data integrity during the download.
    Ok varunedra Lubuntu is reinstalled and wired connection is working. So I should go ahead and try purging and re-installing network-manager package?

    Re: Broadcom BCM4312 wireless card on Dell Mini

    Only if the problem persists after installing "linux-firmware-nonfree" package as before. So install that one first, as it is required to make the native driver work -
    Code:
    sudo apt-get install linux-firmware-nonfree
    Reboot and make sure you can connect, using the previous fix if required.

    Then run "nm-applet" in a terminal again and see if it works this time. If not, and it returns the same error as in post #25, then please do an update -
    Code:
    sudo apt-get update
    sudo apt-get dist-upgrade
    ..then proceed with reinstalling network-manager packages as mentioned in post #28. You can confirm whether ALL the required packages are actually downloaded to the system or not by looking in the /var/cache/apt/archives directory. Look in it BEFORE running the first command in post #28, then again AFTER running it. If there are new packages in it (especially network-manager-gnome...., network-manager.... etc.), proceed with purging/reinstalling.

    Hi varunendra I've been away for a while sorry for the delay in replying. I decided to install Xubuntu 14.04.1 as Lubuntu was doing my head in. Again, wireless is not working for me on Xubuntu. I've installed linux-firmware-nonfree and rebooted but no luck. I've tried creating a wireless network connection as before and that isn't working. nm-applet (icon with an up and down arrow) is on the panel and it also appears on the panel when I enter nm-applet into the terminal, so i assume it's working ok. Can you please help me to get this problem sorted, thanks.

    ..the up/down arrow icon usually indicates an active Ethernet connection. Can you try the wireless without the ethernet cable plugged in? Reboot with the cable unplugged if required. If the wireless doesn't detect any available networks, please try -
    Code:
    sudo iwlist scan
    ..and see if it can detect the available networks now and connect to the desired one. If not, please post a fresh report of the wireless_script.

    PS:
    You shouldn't direct your posts to specifically me when you have so many great personalities of the wireless team on your thread.

    Thanks varunendra, yes I rebooted and tried wireless with the ethernet cable unplugged but no wireless networks were detected.

    I take your point varunendra, I meant no offence to any of the guys on the wireless team by directing my post to you, it was just because you had been dealing with my problem in depth. I welcome and appreciate input from all of you : ]

    Please try that again, with a working wired connection -
    Code:
    sudo apt-get install linux-firmware-nonfree
    Post back its output/errors here. If there are no errors, you should have a working wireless after a reboot.

    Hmm.. looks like it's time to go manual..

    Please download the attached zip file onto your Desktop. Then open a terminal, and run the following commands in it -
    Code:
    cd Desktop
    unzip b43.zip
    sudo mkdir -p /lib/firmware/b43
    sudo cp b43/* /lib/firmware/b43
    Reboot, and check -
    Code:
    dmesg | grep firmware
    If no errors, you should have a working wifi. If the error messages do show up again, please post back the output of -
    Code:
    ls /lib/firmware/b43
