    Saudações,

    E... bem-vindo Debian 8 (Jessie)... creio que esta seja a melhor maneira de iniciar esta postagem.

    O sistema está instalado e 99,9% está ok!

    Entretanto, faltou o famigerado wifi da Broadcom funcionar.

    Debian 8 com a Broadcom BCM4312 LP-PHY e PCI-ID final 4315


    Durante a instalação, o Debian avisou que poderia carregar o firmware non-free via pen drive, cartão SD, etc.
    Eu ignorei esta tarefa pensando que poderia instalar de forma automatizada, via APT, como dantes no Debian 7.

    Segundo a informação do comando apt-get, no Debian 8, o pacote firmware-b43-installer substitui o  firmware-b43-lpphy-installer.

    Eu não cheguei a testar o pacote firmware-b43-installer ... resolvi fazer manualmente as coisas!

    Para saber o final do seu PCI-ID execute, como root, e observe a saída do seguinte comando:

    # lspci -nn -d 14e4:

    01:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)

    Sem final 4315? Procure mais informações nos links:
    https://wiki.debian.org/bcm43xx
    https://wireless.wiki.kernel.org/en/users/Drivers/b43#Supported_devices

    Ainda como root, ative os repositórios contrib e non-free no seu sources.list. Ex.:

    # cat /etc/apt/sources.list
    ...
    # contrib and non-free
    deb http://ftp.us.debian.org/debian/ jessie contrib non-free
    deb-src http://ftp.us.debian.org/debian/ jessie contrib non-free

    Atualize o cache do APT...

    #  apt-get update

    Certifique-se de instalar os pacotes wireless-tools e b43-fwcutter...

    #  apt-get install wireless-tools b43-fwcutter

    Agora, baixe o firmware em http://downloads.openwrt.org/sources...

    #  cd tmp

    #  wget 'http://downloads.openwrt.org/sources/broadcom-wl-5.100.138.tar.bz2'

    Descompacte e acesse a pasta do firmware...

    #  tar xjf broadcom-wl-5.100.138.tar.bz2

    #  cd broadcom-wl-5.100.138/linux

    Crei a(s) pasta(s) de instalação do firmware...

    #  mkdir -p /lib/firmware/b43

    Extraia o firmware na pasta /lib/firmware/b43...

    #  b43-fwcutter -w /lib/firmware wl_apsta.o

    Apague os arquivos usados para a instalação...

    #  cd tmp

    #  rm -Rf broadcom-wl-5.100.138*

    Reinicie o sistema e aproveite o seu famigerado chip com PCI-ID 14e4:4315.



    Paz a todos!


    Epílogo...


    O Debian 8 foi lançado dia 25 de Abril de 2015, e um dia depois eu o instalei no meu netbook que entes executava o Debian 7.

    Veja algumas capturas de telas...

    Depois que eu instalei o firmware do wifi, os logs passaram...
