    Sorry for the long delay guys. I had a wireless signal for 5 mins...rebooted and it was gone again (after executed some of your advice and turning off wireless power manangement). I will wait until I am at work this morning so I can have a ethernet connection to try again.


    It is a little frustrating that it doesnt seem to connect wirelessly.

    As far as your questions go Wildman, I DONT even know what any of that means!!! lol I DONT think I removed the network manager or set anything to a static ip but maybe I did by accident somehow. As far as Cloning anything...I have NO IDEA. I DID do this per some forum advice though:


    • open the 'Synaptic Package Manager' and search for 'bcm'
    • uninstall the bcmwl-kernel-source package
    • make sure that the firmware-b43-installer and the b43-fwcutter packages are installed
    • reboot

    Please open the file
    Code:
    gksudo gedit /etc/network/interfaces
    and remove anything except
    Code:
    auto lo
    iface lo inet loopback
    Save, close the editor and reboot. This device maybe only supports WEP and WPA encryption, not WPA2. Which of the networks shown is yours? Please show also
    Code:
    cat /etc/udev/rules.d/70-persistent-net.rules
    iwlist chan
    ifconfig -a
    Your router firmware is up-to-date? Channel "fixed", bandwidth to 20MHz, MAC-address filter is off and the network is not "hidden"? Check you router manual for applying these settings.

    I put that code in the Terminal (not sure if that is what you meant or not) and it appeared that nothing happened. It asked me for my administrative password but nothing appeared to happen.

    I dont know what the editor is if we are not talking about the Terminal

    Sorry, you are using Lubuntu, so the 1st line needs to be
    Code:
    gksudo leafpad /etc/network/interfaces

    I did as per your instructions, saved and rebooted and still no wireless connection.
    I ran the next commands and got this:

    Re: COMPLETE Newbie!! Never worked in Terminal b4. Wireless worked initially, now NOT

    Setup a new file because of the strange outputs of "ifconfig":
    Code:
    sudo mv /etc/udev/rules.d/70-persistent-net.rules /etc/udev/rules.d/70-persistent-net.bak
    sudo udevadm trigger
    sudo service udev reload
    sudo service udev restart
    sudo service network-manager restart
    Check:
    Code:
    cat /etc/udev/rules.d/70-persistent-net.rules
    ifconfig -a
    iwconfig
    sudo iwlist scan
    cat /etc/resolv.conf
    iwlist chan
    dmesg | grep iwl

    Do I input ALL of the sudo code stuff at ONCE (copy and paste) or do I need to do them one at a time??? Sorry, this truly is ALL new to me!! Thank you in advance for your help.

    Hi Praseodym. I input the codes per your instructions and now I am MAGICALLY writing to you on a WIRELESS connection!! I even REBOOTED and it came back!! lol

    I TRIED to copy the code results you wanted me to run, but for some reason it will not let me attach the results (say invalid file format). I am going to take this laptop out to a NEW wireless connection today just to see if it can find it!!!

    SO far I am SO HAPPY!!! Thank you for your help everyone!!! I have NO idea what I am doing (obviously) but it sure has sped up what was a USELESS computer (essentially). If can keep it working for a week I think I will actually install Ubuntu on (Not Lubuntu necessarily) on a computer with some greater processing power!

    Thanks again and I HOPE it continues working!!! lol

    I did say the results from the codes you asked me to run afterward, I dont know why I cannot attach them in a proper file format this time.

    For Ubuntu you need at least 1 GB RAM (2 GB recommended!). Alternatively, with less RAM you can try Xubuntu 12.04 long-term support (LTS) or Lubuntu 13.04 (no LTS!)
