[Contexto]
Eu estou instalando um Debian no meu novo computador: uname -a is Linux myname 3.2.0-4-amd64 #1 SMP Debian 3.2.57-3+deb7u1 x86_64 GNU/Linux .
Eu estou tentando usar meu wifi, lspci dá 02:00.0 Network controller: Intel Corporation Centrino Wireless-N 135 (rev c4) . O pacote não-livre iwlwifi está instalado e iwlwifi-135-6.ucode está em /lib/firmware . Minha versão é 18.168.6.1, como link
O gerenciador de rede consegue ver as redes por alguns segundos, tentar se conectar, desconectar e tentar se conectar novamente ... Aqui estão os resumos de dmesg :

Como o problema parece vir do rfkill, eu tentei coisas como sudo rfkill unblock all
. No entanto, sempre que eu digito sudo rfkill list all , recebo:
1: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
3: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
Parece que os switches de hardware estão bem ... Eu também monitorizei os eventos do rfkill ( sudo rfkill event ), e aqui está o que eu consegui:
1400772407.995946: idx 3 type 1 op 2 soft 0 hard 0
1400772410.003509: idx 3 type 1 op 2 soft 0 hard 1
1400772410.004361: idx 3 type 1 op 2 soft 0 hard 0
1400772412.012073: idx 3 type 1 op 2 soft 0 hard 1
1400772412.013314: idx 3 type 1 op 2 soft 0 hard 0
A comutação de rfkill só acontece quando tentativas de conexão são realizadas.
Pode ser um problema relacionado ao modo avião, mas a luz do meu computador está desligada. Tentei pressionar fn + f11 para ligá-lo e a luz nunca acendeu ... Não consigo ver nenhum interruptor mecânico ou fn + .. relacionado ao wifi no meu computador. As pessoas que enfrentam problemas relacionados ao modo avião parecem resolver isso inicializando o Ubuntu 10.10 ... Instalar um debian squeeze ou um Ubuntu resolveria esse problema?
[pergunta]
Aqui estão minhas perguntas:
-
parece um problema de hardware? Um lança-chamas é a ferramenta certa para resolver esse problema?
-
Como faço para encontrar o que está bloqueando o rfkill de tempos em tempos? O firmware pode ser a origem deste problema?
-
o que você tentaria? O que eu posso tentar?
Qualquer conselho seria útil!
