Keep wi-fi connection while asleep? Right now my MacBook Pro is set to go to sleep after 1 hour and then when I wake it back up, I have to wait for it to find/connect to Wi-Fi again.

How can I maintain the Wi-Fi connection so when I wake the computer, it's already connected?

I'm running OS X 10.9.1 on a Retina MacBook Pro.

Here are my Energy Saver preferences:
If your Mac enters its full sleep state, then your network connections will be disconnected. Your Mac can not be connected to a WiFi network and be asleep at the same time.

You can avoid full sleep by setting your Computer Sleep to Never. Your MacBook will then sleep all the sub-systems possible when idle, but will remain awake enough to maintain a WiFi network connection.

PowerNap is not the same as full sleep. This is a special state controlled by Apple and, for now, available only to Apple's chosen processes.
