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
