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)

    Tell us about your network. Router? Model? Have you rebooted the router? What security protocol are you using? When you say "ANY" please elaborate.

    My router is a Netgear WNDR3400v2. It broadcast a total of four networks (2.4 private, 2.4 guest, 5 private, and 5 guest).  All four networks are secured using WPA2 Personal.  I have rebooted the router, backed up the settings and restored the router to factory defaults without any luck.  I am currently unable to see my two 5GHz networks or my neighbors networks that I used to be able to see.  I'm not having any trouble connecting to or seeing any 2.4 GHz networks.

    Sounds like a hardware problem. Maybe time to take it to Apple.

    I have had a new Macbok Pro for about the same amount of time.  No issue with the 5GHz networks.  Hardware issue is the most likely source. 


    Time to go to Apple.  Let us know how the experience is, or if there is another issue.

    Yeah, I have an appointment this evening. I was hoping someone on here knew something I could try first.

    System Preferences>Network>Advanced.

    Try selecting the network and clicking on the minus sign to delete it. Then click OK, then Apply. Reboot your MBP. Then in the airport menu see if the your network appears.
