Hello everyone!
Seem like the issue is finally resolved...
I did two things so now sure exactly which of the two actually resolved the problem:
1. Turned off the Wake On feature for the LAN and Magic Packet entries
2. Switched my power options from Performance to Balanced (recommended)
Once again, although I'm not a 100% sure which was the solution, I think it has to do with the Wake on features of the built in LAN..
Thanks for the help everyone!
