Por que o botão wifi do meu sistema operacional LTS não funciona?

1

Acabei de instalar o Ubuntu LTS 16 no meu laptop Dell. A rede a cabo funciona, mas o botão wifi não funciona. Não há nenhum botão de wifi, nenhum recuperador de wifi ... nada.

Eu tentei reiniciar e reinstalar, mas nada mudou.

Eu acho que a tecnologia wifi não está ativa, talvez.

Aqui está a saída da verificação do meu dispositivo.

Alguma ideia?

Seu problema é que você tem o driver errado instalado para o seu wireless. Com uma conexão de internet confiável, abra um terminal e faça:

sudo apt-get purge bcmwl-kernel-source
sudo apt-get install firmware-b43-installer

Reinicie.
