Well I don't recall what triggered this, but it definitely didn't happen before, whether this was caused by an update or some hardware failure, I'm not sure.
I have a custom built PC, i7-2600k @ 4.5GHz watercooled w/16GB RAM, Samsung 850 pro, etc, this machine is more than powerful for the task at hand.
The NAS is a WD My Cloud 4TB gigabit.
Ya, sadly it's not the same company, which is why I won't be going with their routers either for my next unit.
I guess I'll see if I have a gigabit switch laying around, I know I have a spare switch, just forget what it is.
