Eu tenho um computador espartano. Ele possui um módulo sem fio embutido que, até recentemente, não tinha problemas. O problema atual é o seguinte: toda vez que eu desligo o computador e ele é inicializado, não consigo "habilitar o hardware" para a conexão sem fio. No NetworkManager, estou recebendo uma mensagem "acinzentada" que diz "a conexão sem fio está desativada pela chave de hardware". A chave de hardware está ativada (posso ver o led verde acender e apagar quando pressiono o botão sem fio). A saída de rfkill
estados que não é bloqueada por soft mas está bloqueada por hardware.
Eu tentei o seguinte (rt73usb é o driver do kernel do meu módulo sem fio integrado) como root:
rmmod -f rt73usb
rfkill unblock all
modprobe rt73usb
mas não faz nada.
A única maneira de corrigir esse problema é inicializar no Windows XP (esta é uma máquina de inicialização dupla, mas F16 é o sistema operacional principal de uso). O Windows faz algo que redefine algo. Quando eu reinicio o Fedora, consigo acessar meu wireless conforme o esperado. Mesmo pressionando o botão sem fio, LIGADO e DESLIGADO, funciona como esperado. É apenas quando desligo e ligo novamente que minha conexão sem fio parece ter problemas.
O que posso fazer para corrigir esse problema? A maioria das soluções disponíveis do Google aponta para soluções 'bloqueadas temporariamente: sim' e aquelas que não apontam para a solução acima, mas ambas não funcionam para mim.
Aqui estão algumas informações que podem ser úteis:

rfkill list
mostra? Meu laptop HP (flextronics) tem um problema em que, se eu compilar os WMI
drivers do laptop (permitindo um manuseio mais avançado do switch rfkill), ele recebe bloqueios "flexíveis" e "rígidos" e, às vezes, os links flexíveis recusam-se a obter desbloqueado. rfkill list
ajudaria a identificar um cenário como este.
rfkill event
e então pressiono o botão de hardware, o bloqueio rígido funciona conforme o esperado. Se eu reiniciar e for direto para o linux, a trava de hardware não funcionará conforme o esperado.
