O Wi-Fi do meu laptop parou de funcionar quando atualizei para o Ubuntu 12.04 (trabalhos com fio). Eu apenas reinstalei o 12.04 sobre o meu antigo 12.04, no qual o Wi-Fi não funcionava, na tentativa de restaurar quaisquer configurações que eu possa ter alterado acidentalmente, mas ainda assim não funciona. Eu também usei uma conexão com fio para instalar atualizações no caso de este bug ter sido corrigido, mas não foi.
Aqui está o resultado da rede sudo lshw -class:
