Computador não está ativando driver wireless !

[phprogram]

          Meu computador, após a intalação do Ubuntu, não funcionou mais a wireless. Já verifiquei nos drivers adicionais e fala que está funcionando perfeitamente.

Dados do computador:

Dell Latitude D531
Processador AMD Sempron
Ubuntu 11.04 32 bits

[zekkerj]

Execute os comandos abaixo e cole o resultado aqui.

sudo lshw -C network

iwconfig wlan0
ifconfig -a
nm-tool

[phprogram]

Desculpa pela demora, estive com alguns problemas e não houve a possibilidade de responde-lo. Segue o resultado abaixo:

Baixe e instale os pacotes "bcmwl-kernel-source" e "b43-fwcutter".

sudo apt-get install bcmwl-kernel-source b43-fwcutter

[phprogram]

Instalei mas nada ocorreu. A wireless continuou sem funcionar !

[zekkerj]

Reinicie a máquina, depois execute novamente os comandos que pedi lá em cima.

[phprogram]

Já havia reiniciado e feito isso mas continuou sem funcionar !

[zekkerj]

... o resultado dos comandos?

[phprogram]

Resultado após o reiniciamento:

OK, o driver ainda não carregou, por algum motivo.

Tente executar os comandos abaixo, e cole o resultado aqui:

sudo modprobe -v wl
dmesg | tail

[phprogram]

O primeiro comando não aconteceu nada. O segundo apareceu isso:

[ 4361.660910] keyboard: can't emulate rawmode for keycode 240

[zekkerj]

Bom, o "modprobe", sem parâmetros, normalmente não dá saída nenhuma mesmo; a função do "-v" é justamente fazer ele dizer alguma coisa, algo como "loading module wl.ko" ou coisa parecida.

A saída do comando "dmesg" seria pra confirmar a carga do módulo. E não apareceu nada, também. É, isso definitivamente está estranho.

Execute mais um comando, por favor. Como de costume, cole o resultado aqui.
