Olá. Tentei o comando:
# apt-get install b43-fwcutter linux-firmware-nonfree

Depois me apareceu a seguinte mensagem:

# apt-get install b43-fwcutter linux-firmware-nonfree
E: Não foi possível obter trava /var/lib/dpkg/lock - open (11: Recurso temporariamente indisponível)
E: Não foi possível obter acesso exclusivo ao directório de administração (/var/lib/dpkg/), outro processo está a utilizá-lo?

Aproveito e pergunto como saber se já tenho instalado, caso já tenha instalado? Pois não me lembro.

Oxi, agora que vi, escrevi errado, o certo é:

firmware-linux-nonfree

hehehe, desculpem, mas e como disse o Vinícius, instalou o firmware-linux-nonfree ?

Abraços.

E o linux-firmware-nonfree?

Olá.

Sim. Já tenho instalado o b43-fwcutter. Instalei pelo Synaptic.

No meu notebook anterior eu usava a Broadcom sem problemas e dificuldades, mas antes tive que instalar esses pacotes:

# apt-get install b43-fwcutter linux-firmware-nonfree

Verifique se você tem eles instalado.

Olá.

Também estou com este problema atualmente. Estou usando um notebook STi IS-1451, e já tem mais de 1 semana que tento varias alternativas para solucionar, mas nada de resolver este problema. Pesquisei em fóruns, sites, etc. e em ultimo caso decidi "incomodar" :-[ a comunidade e pedir ajuda aqui.

Fiz todos os passos iniciais depois de instalar como:

Atualizar a source.list com contrib non-free;

# Debian 8 "Jessie"
deb http://httpredir.debian.org/debian/ jessie main contrib non-free

Instalei o firmware b43 através do Synaptic;

No link: https://wiki.debian.org/wl , fiz os procedimentos:

Installation

    Add a "non-free" component to /etc/apt/sources.list for your Debian version, for example:

    # Debian 8 "Jessie"
    deb http://httpredir.debian.org/debian/ jessie main contrib non-free

    Update the list of available packages. Install the relevant/latest linux-image, linux-headers and broadcom-sta-dkms packages:

    # apt-get update
    # apt-get install linux-image-$(uname -r|sed 's,[^-]*-[^-]*-,,') linux-headers-$(uname -r|sed 's,[^-]*-[^-]*-,,') broadcom-sta-dkms

    This will also install the recommended wireless-tools package. DKMS will build the wl module for your system.

    Unload conflicting modules:

    # modprobe -r b44 b43 b43legacy ssb brcmsmac bcma

    Load the wl module:

    # modprobe wl

Digitei o comando:

# iwconfig wlan0
wlan0     No such device

Instalei o laptop-mode-tools através do Synaptic.

Alterei o WIRELESS_BATT_POWER_SAVING=0 dentro de /etc/laptop-mode/conf.d/wireless-power.conf e reinicie o notebook

Depois disso não consegui mais visualizar o wlan0. Antes de fazer os comandos acima do site https://wiki.debian.org/wl eu conseguia visualizar, porem sem ter acesso ao Wifi.

Depois pesquisando em alguns fóruns descobri alguns comandos que me mostra as informações sobre o wifi, que pode ser útil. Me apareceu isto:
