tentando configurar sem fio

Estou tentando configurar o wireless no laptop Dell Vostro 1520, com a última instalação do Ubuntu. Aqui está a saída de alguns dos comandos que me disseram para executar:

Com os lançamentos do Ubuntu 11.x, os drivers proprietários da Broadcom pararam trabalhando com os chips Broadcom 4311 (veja o bug 732677), e talvez bug também afeta o chip 4312. No entanto, seu chip funciona bem com a abertura b43 driver, mas primeiro você precisa instalar o firmware - facilmente feito com uma instalação de pacote. Se instalado, remova o driver STA proprietário (e seus arquivos de configuração que suprimem o driver b43 funcional) por invertendo o que você fez para instalá-los:

sudo apt-get purge bcmwl-kernel-source

e / ou executar drivers adicionais e desmarcar o driver STA da Broadcom

Verifique se sua remoção / desativação acima está concluída:
todas as linhas com "blacklist b43" deveriam ter sido removidas de todas arquivos em /etc/modprobe.d . Essas linhas de lista negra suprimem o driver b43, então eles devem ser removidos - apenas os exatos "b43" e b43legacy, deixe o bcm43xx sozinho. Lide com quaisquer sobras:

sudo rm /etc/modprobe.d/blacklist-bcm43.conf  
gksudo gedit any-file-found-with-b43

e exclua ou coloque um # no começo.

O firmware proprietário não pode ser distribuído com o lançamento, então você tem que adicioná-lo manualmente. Use uma conexão com fio e em um terminal:

sudo apt-get update  
sudo apt-get install b43-fwcutter 

e aceite a oferta para baixar os arquivos da Broadcom, que colocará o firmware da Broadcom em / lib / firmware / b43. Se você não obtiver a oferta de download, purgar o pacote e tente novamente:

sudo apt-get purge b43-fwcutter

sudo apt-get install b43-fwcutter

Você pode até usar o firmware de código aberto (que é o que eu uso):

sudo apt-get install firmware-b43-installer

mas apenas um conjunto de firmware é necessário (e os usuários não-4311 devem verifique se precisa de outras versões do firmware (como firmware-b43-lpphy-installer). Se ambos os conjuntos de firmware presente, o conjunto proprietário em /lib/firmware/b43 será usado.

Com o firmware no lugar, o NetworkManager pode iniciar a digitalização, Caso contrário, carregue manualmente o módulo do driver b43 ou apenas reinicialize.

sudo modprobe b43

NetworkManager deve começar a digitalizar e oferecer uma lista de possíveis pontos de conexão em poucos segundos.

Selecione seu ponto de acesso, selecione o método de criptografia correto e digite sua chave. Se você não está transmitindo seu ssid e ele não aparece a lista de pontos de acesso, você pode ter que clicar em NetworkManager e selecione o item de menu "conectar à rede oculta" e digite seu ssid. Próximo boot, a conexão deve ser automática.
