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 

A bad PSU, "too smart" UPS unit (or a power surge strip) can be also 
making noise here...
