Problema com wireless broadcom bcm4312 802.11b/g - Ubuntu 11.10

[mzk]

Por algum motivo minha rede wireless desconecta a cada 2 minutos, tentei reinstalar o driver mas não funcionou.

também gostaria de saber se é possível utilizar a placa broadcom bcm4312 802.11b/g em modo monitor.

uso Ubuntu 11.10

alguém pode me ajudar?

tbm tentei colocar o driver wl na blacklist mas não deu certo, o que voce acha que pode ser?

[zekkerj]

Vc chegou a tentar usar o driver nativo, em vez do proprietário?

[mzk]

Vc chegou a tentar usar o driver nativo, em vez do proprietário?

Tentei, mas sou novo em linux, não sei direito como fazer, poderia me ajudar ?

[zekkerj]

Apenas volte ao gerenciador de drivers proprietários e restaure o driver original. Vc também vai precisar instalar o pacote de firmware ("firmware-b43-lpphy-installer").

[mzk]

não deu =\

[zekkerj]

O que não deu?

[mzk]

tentei modificar o driver da maneira que voce sugeriu, mas o problema permanece.

da para modificar o driver pelo prompt?

[zekkerj]

Dá. Mas primeiro vc tinha que desativar o driver proprietário, e a melhor forma de fazer isso é da mesma forma que vc o ativou, ou seja, pelo gerenciador de drivers proprietários.

Execute novamente os comandos lá de cima, pra gente avaliar como está sua máquina agora.

execute os comandos abaixo e cole o resultado aqui.

Era pra ser isso?

[zekkerj]

Vc continua com o driver proprietário. Chegou a desativá-lo, como eu sugeri?

[mzk]

Sim, fiz da maneira que recomendou e o resultado foi este.

[zekkerj]

Bem, vamos fazer isso manualmente então.

Execute os comandos abaixo, cole o resultado aqui.

sudo modprobe -rv wl
sudo modprobe -v b43

sudo lshw -C network

iwconfig wlan0
