iMac refuses to sleep intermittently

[elasticmedia]

I have had problems with my various Macs awakening randomly. I had a core2 duo iMac and now I have an i7 iMac, and it seems that I have a pattern. I sleep the computer and it comes on suddenly. Sometimes it goes off, but other times it stays on. I have set up the computer to go to sleep after 25 minutes: both the display and the computer. I have checked "put hard disks to sleep when possible".

I have tons of RAM and am running Mavericks. I run Parallels desktop too. I have a first generation time capsule and a 2Wire DSL modem. The 2Wire has wireless capabilities, but I just have it feeding the time capsule with a single ethernet cable. My wife's macbook Air wirelessly and automatically backs up to the time capsule as well. I have a brother wireless laser printer and an HP wireless inkjet printer. I plug in a Denon audio receiver via ethernet to the time capsule. There is a ROKU box that connects wirelessly to my network. I don't have file sharing turned on, but I do have dvd/cd sharing checked. I don't have any other remote management protocols set up.

After I upgraded my computer to a new (used) iMac, I was dismayed to find the problems persisted. I have been scratching my head and wondering whether it could be the time capsule or the 2Wire that is the problem? I have not tried disabling time machine for either computer to see if that was the issue. I have not unplugged the time capsule and just used the 2Wire modem to trouble shoot.

I know there are certain things that can be queried via Terminal, but I don't know enough to choose what to type in. I sometimes want to tear my hair out when the computer suddenly coms on in the middle of the night, or when I can tell it has been on for hours in the morning, by touching the iMac and feeling it to be very warm.

Can you search for "sleep" in Console and paste the results - that may tell us what's causing it.

Here are some lines from console from yesterday. There are a lot of the "sleep for 1 seconds and then try again" generally about 1 per second when that is going on.
