lo no wireless extensions.
eth0 no wireless extensions.
pan0 no wireless extensions.
*Note que não aparece wlan0
Detalhe importante: Isso aconteceu depois de eu resolver um outro problema, fazer com que o ubuntu reconhecesse minha placa de som através deste procedimento:
https://help.ubuntu.com/community/SoundTroubleshooting Outro detalhe importante: O ubuntu 8.10 não reconhece automaticamente placas de rede da Atheros, então logo após a instalação tive que recorrer a este procedimento para poder usar a net:
http://ubuntuforum-br.org/index.php/topic,48058.msg281528.html#msg281528 Isso resolveu o meu problema até que wlan0 desaparece sem mais nem menos. Tentei reutilizar aquela dica novamente mas o terminal não reconhece o código modprobe ath5k, com sudo ou não. E não consigo reinstalar o pacote linux-backports-modules-intrepid-generic porque estou sem conexão no ubuntu.
Bom... espero que isso ajude. Abraço.
