I purchased a MacBook Pro w/ Retina display four days ago.  Up until earlier today I was connected to a 5 GHz network.  Suddenly, I can no longer see, much less connect to, ANY 5 GHz network. Does anyone have any ideas on how to fix this, please?

MacBook Pro (Retina, Mid 2012), OS X Mountain Lion (10.8.2)
