    I have this ongoing issue.

    If I run my Mac Pro for a few days all of a sudden the WiFi will disappear. Basically if I click the WiFi icon on the top menu bar it will show that the WiFi is turned on, but no networks can be found. However in Network preferences it will show that the WiFi has been turned off, and if I try to turn it on, it doesn't.

    If I restart the computer, the issue will go away. I don't need to reset anything, just a reboot will resolve the issue. It's not a network interference issue as I have the only 5GHz wireless AC network in my computer's reception vicinity and I don't have this issue on any of my other computers.

    When this happens, in console I get these messages:
    Code:
    8/26/14 12:29:28.000 AM kernel[0]: AirPort: Link Down on en2. Reason 2 (Previous authentication no longer valid).

    I'm running Yosemite DP6.

    Any ideas? I'm thinking this is a hardware issue unless someone else things otherwise?

    There's your problem... I have experienced the same thing on my MacBook Pro... It should be solved by release day.

    Thanks for your reply.

    I don't have Yosemite on my MacBook Pro, so I am unable to duplicate this issue. I'm glad to hear it's a software one then.

    Has this been confirmed as a Yosemite issue? It only just started happening to my 2013 Mac Pro, which is on Yosemite, but that hasn't changed in the last year and a half.

    I've been having wireless weirdness since the 10.10.5 update, bluetooth and wifi dropping out, reboot bringing bluetooth back, but showing wifi hardware as not installed, second reboot everything back to normal. I was actually starting to wonder if it's a conflict with my xbox 360's wireless controllers, as I've got the console and computer spatially oriented in a new way with respect to each other.
