Well, I’m back. Bummer.
After setting the static IP on the router and the EX4100, it stayed up for 15 days. Set to power up for 12 hours per day.
Then same old thing. Locked up solid. Power and reset button don’t function. No network connection. LCD on device looks normal with all indicator lights showing blue as though there were nothing wrong.
Had to unplug it to get it to reboot. For now, I plan to let it ride and hope for a firmware upgrade to address the problem. Eventually I’ll open another support case if it continues to happen.
Just thought anyone following this thread should know. BTW I’ve never had any response from anyone at WD by way of this forum. Not sure if that is supposed to happen, or not.
Best to all,
