    Hi,

    I'm terribly surprised this situation.
    I was working on a laptop connected to a Wifi network.. Until suddenly my wireless network card suddenly disappeared - Jesus Christ - where she is?!
    I do not have any switches on my laptop for turn OFF/ON wireless card.

    I attach a log file with all incidents.

    The only way to recover card is restart computer.
    Please Help, I have no intention of restarting the computer every day

    感觉像是firmware或者内存本身的问题
