After fast reboot (electricity off - on) wireless leds statuses remains off and wireless network doesn't show up.
If i wait 20 -30 seconds after shutdown and up, it works. It is not stable. What could be the problem ? Capacitors ?
Apparently your equipment is faulty. I would recommend returning it to your seller.
I tried to reproduce the issue you described, but my device works absolutely correctly with the latest firmware version.
