Eu tenho um computador espartano. Ele tem um módulo sem fio embutido que até recentemente não tive problemas. O problema atual é o seguinte: toda vez que eu desligo o computador e inicializo de volta, não consigo "habilitar hardware" o wireless. No NetworkManager, estou recebendo uma mensagem 'acinzentado' que diz que "a rede sem fio está desativada pela troca de hardware". O comutador de hardware está ativado (consigo ver o led verde ligado e desligado quando pressiono o botão sem fio). A saída de rfkill
indica que ela não está bloqueada, mas é bloqueada com segurança.
Eu tentei o seguinte (rt73usb é o driver de kernel do meu módulo sem fio integrado) como root:
rmmod -f rt73usb
rfkill unblock all
modprobe rt73usb
mas não faz nada.
A única maneira que consegui 'corrigir' esse problema é inicializar no Windows XP (esta é uma máquina com inicialização dupla, mas a F16 é o principal sistema operacional de uso). O Windows faz algo que redefine alguma coisa. Quando eu reinicio de novo no Fedora, consigo acessar meu wireless como esperado. Mesmo pressionando o botão sem fio ON e OFF funciona como esperado. É quando eu desligo e, em seguida, ligo novamente que meu wireless parece ter problemas.
O que posso fazer para corrigir este problema? A maioria das soluções disponíveis do Google apontam para soluções "soft block: yes" e aquelas que não apontam para a solução acima, mas ambas não funcionam para mim.
Aqui estão algumas informações que podem ser úteis:
