    Acer 5520 and Ubuntu 12.04 = no wifi

    Hello all,

    I have just taken a dead laptop back into the world of the living, and there may still be some hardware issues so possibly the software is not to blame, but perhaps you can help....

    I have had a dead hard drive, totally wiped, instead of buying windows i have opted to leap into the world of Ubuntu, so i am very new at this. But the point to be made is i do not have a windows system to boot and im aware there may be an easy (ish) fix if i could.

    I have an Acer Aspire 5520 and just installed Ubuntu 12.04 and i find my wifi does not work, it seems that it is not even nearly working as i cant even see any wifi networks. i have a button on the keyboard to turn on/off wifi but it does nothing and i have found many posts from other members who have had the same issue but none of the solutions on those threads have solved my problem.

    let me know what other info you need to be able to even begin to help, and hints towards a fix would be fantastic!

    many thanks

    Please hook up the ethernet and do:
    Code:
    sudo apt-get install linux-firmware-nonfree
    Reboot and give us your report.

    Re: Acer 5520 and Ubuntu 12.04 = no wifi

    Hi Chili555

    ran the code and all went well no errors or warnings,

    rebooted and unplugged ethernet and no connections on startup

    The wireless symbol in the toolbar top right is showing no animation or sign of even trying to do anything.

    Let's see what's going on under the hood. Please run and post:
    Code:
    sudo modprobe b43
    dmesg | grep b43
    Thanks.

    Re: Acer 5520 and Ubuntu 12.04 = no wifi

    Looks perfect! Now is there a wireless interface?
    Code:
    iwconfig
    Does it scan?
    Code:
    sudo iwlist wlan0 scan
    When you click the Network manager icon, do you see your network? Can you click it and connect?
