[resolvido] Kubuntu 12.10 não reconhece a placa ethernet Atheros AR8162

[marco_smachado]

Minha placa Atheros AR8162 não tinha sido reconhecida de primeira, então segui estas dicas (http://bit.ly/SO0ENg). Após realizar uma atualização no sistema, a mesma parou de funcionar. Já re-fiz o passo-a-passo, mas não adiantou.

Alguém passou por esse problema com essa placa?

Mais um comando por favor.

sudo lspci -v -k -n -s 02:00.0

Desculpe a demora.

Segue a saída do comando sudo lspci -v -k -n -s 02:00.0:

Vc chegou a verificar se o módulo ainda está disponível? O comando abaixo vai dar informações sobre o módulo "alx", que parece ser o apropriado pra essa placa.

modinfo alx

[marco_smachado]

Verifiquei agora que o módulo não estava mais presente.
Então decidi reinstalar tudo novamente, dessa vez reinstalei até o linux-headers-generic e o build-essential, com isso a placa voltou a funcionar utilizando o módulo alx.

Obrigado zekkerj pela ajuda e pelas dicas

[zekkerj]

Demorou mas consegui localizar: esse módulo pode ser instalado com o pacote "linux-backports-modules-cw-3.6-3.5.0-19-generic".
