    My 2 cents on this: I have been seeing this regularly on my late 2011 MBP, also when plugged in. I have also been using Transmit and the Disk Menu.

     

    Have disabled the menu item recently and it seems to be fine now. Will continue testing.

    None of the mentioned solutions seem to work for me. My MBP will freeze after sleep. Pluged in or battery it does not matter. I do not have transmit installed. I do have Dropbox. But the issue still remains. I will put the computer to never sleep until someone at apple finds a solution.

    It happened virtually every time I put my MBP to sleep. Clearing out old networks and reestablishing my home network helped for light sleep, but it still happened on deep sleep. Disabling Transmit on the menu bar (sad as it was to do so) seemed to clear things up for me entirely. Happened once on my iMac, but only once.

    Thanks for the post Cabel.

     

    After deleting the Transmit plist file (backup favs first), turning the Transmit menu bar icon ON and then OFF and then Reseting my power settings back to default (in system prefs)... I haven't had the problem since (2 deep sleeps). We'll see if thats all it takes.

    I am having the same problem with my 17" MBP. Restarting does not bring my WiFi back, but I have noticed when this occurs from sleep, shutting down often requries me to force the comptuer to shut down. I have tried clearing my networks too, to no avail. What DOES seem to work is to shut down, restart and run YASU to clear the caches. Then it seems to work fine again. It looks like a cache file is getting corrupted somewhere.

    ok - my problem now seems to be solved - I had deleted old networks in system prefs and recreated my preferred network manually. I was prompted to choose preferred each time and it was not remembered. So I deleted the network again, let it find it on its own instead of creating it manually. Now the system is remembering and connecting to my preferred network. I haven't re-installed transmit, dropbox, google drive or any login items yet. Will test this for a bit and then try those.

    Removing Transmit from the menu bar fixed the issue for me.

    I've sent Cabel a trace from the exact moment that the computer crashed. It looks like Bonjour Networking is what's actually crashing/failing.

     

    But, disabling Transmit menu seems to work for me too.

    I have the same problem, I'm using a iMac, I thought this was happening only when waking up from sleep but I saw that also happens when you deactivate the Wifi and activate it again, its random sometimes stops working and sometimes doesn't but most of the times it doesnt work just like when comming back from sleep.

    Hmm, interesting.  I too have the same exact issues (wether plugged in or not) with networking freezing.  And, I too you the Transmit Disk mounting menu.  Will disable now and see if that helps.

    Yeah I'm having the same issue.  I've been reading through all the possible solutions but the fact of the matter is that we shouldn't have to try out all these complicated fixes.  Apple should fix it, not us.  We should be focuses out energy on pressuring them for a fix rather then trying out all these trial-and-error fixes.

    Seems that my issue has cleared up. I turned off Transmit on the menu bar and when Cabel posted, I thought I'd turn it back on to see if it happened again. It has not. So, for me, turning off and then on Transmit on the menu bar cleared up the issue.

     

    To sharpmachine—Apple monitors these message boards. When I was having a very difficult time with the screen flickering on this (or the machine it replaced) iMac, even after three or so fixes by Apple. One day, out of the blue, I got a call from Apple, asking if I would mind exchanging my iMac for a new one. Mine was one of the few that were having the problem and their engineers wanted to look at it. By that time, it was a few months old. I told them my local Apple Store, then backed it up twice and cloned the HD. I got a brand new one that has never had any issues. They pay attention, for good and for not-so-good. There have been threads that it would appear that Apple has deleted, although I don't remember any details.

    Yeah, I turned off the Transmit menu bar as well and put the computer to sleep and went out for the day and came back and boom!  Wifi connected no problem.  So it seems it's not may not be an OSX issue but rather a Transmit issue.

    I had it working well for a while after my previous post but then I had 2 crashes this evening. Reseting Energy settings, turning ON and then OFF the transmit menu icon and clearing Transmit plist file. Seemed to work but no dice I guess. Gonna just not let the machine go to sleep at this point. Jeez.
