Funcionava bem com o Windows 7.
O interruptor de hardware não está desativado. Eu o alternei dezenas de vezes. A luz do wifi nunca liga e sempre é listada como hardware desativado. Eu tenho as atualizações mais recentes instaladas.
Eu tenho procurado por soluções, mas nenhuma delas parece funcionar para mim. Eu tentei remover o acer-wmi. Eu tentei definir 11n_disable = 1. Eu tentei reiniciar o BIOS. Eu tentei usar rfkill para desbloquear (apenas remove o bloco de software). Eu reiniciei dezenas de vezes. A luz do wifi desliga assim que o grub é carregado.
Edit: Eu tenho um nic usb sem fio edimax. Ele também mostra hardware desativado (embora listas de rfkill sejam desbloqueadas). Se eu descarregar o iwlwifi, o usb nic funciona bem.
