Mac Mini wifi reconnection problem after waking from sleep

New Mac Mini 2012 ivy5, Mountain Lion, up-to-date in software.

Every time I turn my computer back on, by pressing a key or moving the mouse, after going to sleep...I go to use the browser and suddenly I realize it has dropped and not reconencted back on to my network. I have to manually find my network each time and re-select it. Oh and it seems to lose sight of my network as it takes a second or two for it to refresh available networks and actually show mine back on the list.

Why is this happening? I have the "wake for network" checked in Energy Saving settings and this seems to be happening way more often (way to often for my satisfaction) than my older Macbook Pro 2009 which has the same Mountain Lion OSX. I had a few issues when I installed ML on the MBP, but a few months back that problem was far gone.

Any settings I am missing or has this bug yet to be squashed for the Mac Mini? I had read months ago when ML OSX came out about this scenario, but I would figure that by now they would have addressed this annoyance already!

Thanks for the thoughts/suggestions..

Mac mini, OS X Mountain Lion (10.8.2)

Hi, this has worked for a few...

Make a New Location, Using network locations in Mac OS X ...

http://support.apple.com/kb/HT2712

10.7 & 10.8…

System Preferences>Network, top of window>Locations>Edit Locations, little plus icon, give it a name.

10.5.x/10.6.x/10.7.x instructions...

System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose Set Service Order.

The interface that connects to the Internet should be dragged to the top of the list.

10.4 instructions...

Is that Interface dragged to the top of Network>Show:>Network Port Configurations.

If using Wifi/Airport...

Instead of joining your Network from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed.

For 10.5/10.6/10.7/10.8, System Preferences>Network, unlock the lock if need be, highlight the Interface you use to connect to Internet, click on the advanced button, click on the DNS tab, click on the little plus icon, then add these numbers...
