Okay, so the fact your system powers off the ethernet adapter "randomly"
is the key of the problem. This should not happen.
As the network interface comes integrated within the motherboard, I would
look for a BIOS update and check if it solves someting related to power
management or WOL (hint: most of the manufacturers do not write down the
full BIOS release changelogs unless you directly contact them, so it's a
good idea to ask the motherboard's manufacturer directly and query about
this).
A bad PSU, "too smart" UPS unit (or a power surge strip) can be also
making noise here...
