Chosen Solution
I need help with my Asus z580c, the wifi is like death, it does not work, you start it but nothing happens, when yo seek into hardware info, it appear wifi undetermined
i solved, open the table, disconnect the battery, remove the sd card put it on again, reconnect the battery. Ah voila there is again the wifi connection.
I just powered down and removed the SD card and that fixed the problem.
