Eu tenho um novo laptop lenovo thinkpad edge e540 e eu instalei o Ubuntu 13.10 nele, mas agora eu não sou capaz de se conectar à internet via wifi. Parece que o Ubuntu não pode usar o meu cartão de Wi-Fi, não há nenhuma opção nas configurações do sistema para gerenciar a conexão sem fio em tudo. Conexão com fio funciona. Alguém pode me ajudar?
Aqui estão mais informações sobre o hardware:
