I'm on Yosemite; on both my iMac and MB Pro, I can't put the computers to sleep when it's connected to the wi-fi; I have to turn the wi-fi off, and then it'll go to sleep. Has anyone else encountered this problem and do they have a solution? I'd like to be able to keep the internet connected when want to do this.

It's been unchecked and it still does it.
Launch the built-in Activity Monitor application and select the Energy tab. Select

Copy the selected text to the Clipboard by pressing the key combination command-C.
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window by pressing the key combination command-V. I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting.
Wait for a new line ending in a dollar sign ($) to appear below what you entered.
The output of the command will be automatically copied to the Clipboard. If the command produced no output, the Clipboard will be empty. Paste into a reply to this message.
The Terminal window doesn't show the output. Please don't copy anything from there.

It worked; thank you very much. One more question -- can you tell me exactly what this feature is? I'm not sure I understand the little explanation in the pane.
It lets you use the Mac as a wireless router.
Can't put Macs to sleep when connected to Wi-Fi.
