    Re: Wifi driver and network setting

    Do an update with a cable plugged in (through update manager) then check 'Additional Drivers' for anything that says 'B43' in it.

    The other option is to install (through Software Centre or Synaptics):

    b43-fwcutter
    b43-firmware-installer

    Restart. Working? That card ( BCM4311 802.11a/b/g) should work out of the box.

    Re: Wifi driver and network setting

    I am not having plugged network.

    I installed b43-fwcutter

    using dpkg -i b43-fwcutter.

    But how can I check if same got installed correctly.

    When trying to install firmware-b43-installer, it is giving error
    (Reading database ... 143118 files and directories currently installed.)

    Re: Wifi driver and network setting

    b43-fwcutter -v

    result

    b43-fwcutter version 015

    Does it mean fwcutter is properly installed?

    If I am trying to install

    sudo apt-get -i b43-fwcutter

    I am getting similar error no Chroot environment found

    Do I need to reinstall b43-fwcutter
