I have also had this issue since I installed windows 8.1. I don't use the homegroup as I have a WHS, so it is disabled on my desktop. I tried disabling IPv6 but still it would not sleep automatically. I have just found windows 8.1 LAN driver on Asus website and installed. On my first sleep test it went to sleep but woke up straight away, so I checked the settings and the intel properties menu is very different from previous versions. I noticed a Wake on Pattern Match option, by default it was checked, I unchecked and my PC stayed asleep. I can still also wake it using lights out from my server.
As you can see these wake patterns are determind by the OS, I wonder if this is something new added to Windows 8.1, may this is causing the issue.
I will keep testing to see if the updated drivers have fixed the issue and will report back.
