I do not know if it relates to my issue.

I do not see a module version in a form that is familiar to me.
It occurred to me that since the machine supports wake-on-lan, that as
long as there is power to the box the network "card" must be active.
This could explain why a change in state only occurs through a
power-off cycle. Does this help?
