    I own a Mac Mini late 2012 and today I noticed that if I enable my Wi-Fi, the Mac Mini does not detect any wireless networks. It's not really a big issue for me since I am constantly connected via Ethernet but I would like to know if there's something I can do to regain wireless functionality.

    One thing that pops to my head and could be related is that a few months back, I opened my Mac Mini in order to install a second hard disk. Although I was extremely careful not to break any connectors, I guess it might be possible that something went wrong.

    On the other hand, If I had damaged the wi-fi, should't OSX refuse to detect my WiFi card to begin with? When I go to "System Preferences", "Network", I am able to turn on Wi-Fi on without problems, it's just that I can't detect any wireless networks around me whatsoever. I am also pasting the output from wi-fi section of System Information

    Software Versions:
    CoreWLAN: 5.0 (500.35.2)
    CoreWLANKit: 4.0 (400.35)

    I have tried all the obvious troubleshooting steps (reboot Mac Mini, reboot Modem/Router, disable Ethernet on Mac Mini, disable and reenable Wireless on the Router but nothing seems to help. Any ideas would be greatly appreciated.

    I did try that. However all I'm getting to is a screen where wi-fi is enabled and searching for networks (without finding a single one).

    Normally this would be an open and shut case that the wi-fi antenna is disconnected/broken/defective but OS X reports that the wi-fi antenna is present and the OS is able to turn it on and off. Is there something I can do on OS X? I don't know if it's relevant but I upgraded to Yosemite from Maverick instead of performing a clean install. Maybe something went wrong there?

    How does the OS see the antenna? I know it can see the airport card, but I was not aware it could detect an antenna.

    As previously stated, check your antenna connection.

    Seeing as how an antenna is nothing more than a wire hanging off a card, I would love to know how OS X knows there is an antenna or not.... I've never seen this diagnostic tool within OSX for this but then again I may be wrong and would love to be wrong since it would be helpful when diagnosing wifi problems.

    Well, I opened the mini and everything seemed to be in place. Just to make sure, I removed and reattached the antenna connector from its socket and carefully reinstalled the antenna plate. After booting the mini, I am still unable to detect any wireless networks when I turn on Wi-Fi.

    Any ideas are more than welcome...
