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...

Браво!)) Отличная работа! 5+++!))
BCM4312 LP-PHY (debian 9) работает божественно! Превосходно находит 12 и 13 каналы, без проблем подключается к ним!
Огромное спасибо за проделанную работу!

P.S.:
Два дня пытался завести Wi-fi, пользовался официальными инструкциями - безуспешно! - И тут! WoW!))
Для XFCE следует добавить: # aptitude install wicd
