I share my My Book 4TB over my network using my router (Netgear R6300). Periodically, the drive stops sharing, the router indicates there’s nothing connected and the drive blinks a white light… The only ways I’ve been able to get it to work again is:
Unplug the USB cable and plug it back in.
Turn the router off then on.
Turn the drive off then on.
Is this how it’s supposed to work? Or can some setting be changed?
