Tenho o Ubuntu 12.04.3 LTS em execução no sistema Dell Inspiron 15R. Não encontra conexões sem fio em tudo. Eu tentei ter ajuda de inúmeros tópicos semelhantes discutidos neste fórum ( Sem fio com o Intel Centrino Advanced-N 7260 ), mas sem sorte.
As informações do kernel são as seguintes:

Eu também tentei carregar o firmware conforme sugerido pelo seguinte tópico, mas apenas decepção.
Sem fio para a Intel Corporation 7260 versão 63
Agradeço qualquer sugestão a esse respeito!
Para diagnosticar o problema, vamos carregar o driver e ver se um erro é provocado:
sudo modprobe iwlwifi
Se houver algum erro ou aviso, poste-o. Em seguida, vamos verificar os logs de mensagens em busca de pistas:
dmesg | grep iwl
Quando soubermos o resultado, podemos avisá-lo ainda mais.
