No meu novo Asus A450J, tenho uma placa de rede sem fio Broadcom 43142 (14e4: 4365).
Esta placa WiFi funciona bem sob o Win 8.1 pré-instalado.
Em uma nova instalação de um Ubuntu, meu cartão wifi não funciona.
Eu tentei várias coisas (pacotes deb externos, ndiswrapper, várias instalações do Ubuntu) para fazê-lo funcionar, mas estou sempre preso ao mesmo problema: a placa parece bem reconhecida, mas não consigo ativá-la.
O pacote a seguir está instalado nativamente: bcmwl-kernel-source, ver 6.30.223. De post anterior , isso deve ser suficiente para o cartão funcionar, mas não é.
Um modprobe faz acreditar que está tudo bem:
$ sudo modprobe wl
$ echo $?
0
mas o cartão continua sendo desativado:
$ sudo lshw -C network
*-network DISABLED

Através da janela de configurações de rede, se eu ligar a placa wireless, ela se desliga quase que instantaneamente.
Agradecemos antecipadamente por qualquer dica para resolver isso.
