Oi!
Então eu instalei recentemente o Ubuntu 14.04, mas os drivers do wifi quebraram após a instalação. Agora o wifi é um bloco difícil e eu não consigo reativá-lo. Eu não tenho um botão wifi nem uma configuração no BIOS. Nem mesmo o USB está funcionando. Alguma idéia de como eu posso consertar o wifi?
Desculpe por não fornecer informações suficientes sobre o problema. Eu não estou realmente familiarizado com o script wifi que você vinculou, mas ótima ferramenta, obrigado por compartilhar :-)
Aqui está a saída do script wifi:
