Redes sem fio não estão sendo detectadas Ubuntu 12.04

Question

Redes sem fio não são detectadas no meu Ubuntu 12.04 após a reinicialização. Eu não instalei nada. Acabei de instalar as atualizações automáticas depois que reiniciei o meu laptop. Agora não está detectando nenhuma das redes sem fio.

Answer 1

de acordo com as pistas fornecidas aqui, parece uma regressão para o kernel.

No entanto, o kernel (3.5 Quantal) que você está usando chegou ao EOL (End-Of-Life).

Sugiro que você atualize para o novo suporte HWE (Hardware Enablement Stack), que é o kernel 3.13 Trusty, seguindo estas etapas:

1. Procure por "atualização" no seu traço

2. AbraoGerenciadordeAtualizaçõeseselecioneobotão"Instalar" aqui (você pode atualizar para 14.04.1 como desejar).
