I have located my problem now. (Antminer shuts down after a couple of seconds)

After a few hard resets its clear the problem is the wifi.
Every time I have set the wifi up the Antminer shuts down, and keeps shutting down untill a new har reset is done.

Anyone know why?

Im in contact with Bitmain but it usually takes a few days for an answer.

And yes, I need the wifi to work.
thanks
