Hi Chris, I can't view the topic you linked, but yeah, I kinda wonder if WD is internally aware of this problem but doesn't know the fix yet.
My EX4100 just froze again, so it lasted about 5 days this time. No response to ping, power button does nothing. The last thing I tried was replacing the switch and using two new Ethernet cables, but that didn't matter.
In my opinion it has to be the device. There is no reason for the power button to fail if the problem is external.
The up/down arrows still cycle through status, but as far as I know that's a separate circuit.
I'm going to try turning off cloud access. Like you I am only using this for media sharing and file backup on a home network, and for its RAID redundancy.
I'll see you guys in 3 to 5 days LOL
