My Wi-Fi connection randomly gets turned off (the menu bar icon turns empty as when you manually turn it off), and I cannot get it turned on unless I reboot.

It really is starting to get annoying.

 

When click on the icon and select "turn wi-fi on" from the menu nothing happens.

 

I have mac os x 10.7.5

 

Other than rebooting what do I have to do to get this fixed, and why is this happening.

    Come on people, someone must have a solution.

     

    This is getting ridiculous, I had to reboot twice in the past 30 minutes.

    There must be somehting I can do.

    I know that nvram has nothing to do with networking, but in a desperate try I even reset it with alt-cmd+p+r to no avail. I reset the smc which also did nothing.

     

    In console I keep getting this error

     

    • WLAN adapter PCIE config space was not restored

     

    Anyone....

    Hi,

     

    I run into the same problem, but in my case a reboot doesn't (temporary) fix the problem. I fear that in my case the problem is related to Little Snitch (will open a case @obdev this weekend), since it occurs in combination with Little Snitch (LS).

     

    I blogged about it weeks ago, but after installing LS 3.0.1 it seemed stable, till I installed the latest update 3.0.2. After the mandatory reboot, my wireless was gone again.

     

    The only thing that works for me is re-insert the original OSX DVD (Mountain Lion), reinstall and apply the updates, java etc. to get thing working again.

     

    Will add new/more information to this thread later on.

    Found a solution (so far) to my problem (do this at your own risk!!!):

    • Remove the following files from the OS:
      Go into /Library/Preferences/SystemConfiguration/ and delete:
      com.apple.airport.preferences.plist
      com.apple.network.identification.plist
      com.apple.smb.server.plist
      NetworkInterfaces.plist
      preferences.plist
    • Remove the wireless adapter from the network section in System Preferences by clicking the minus under the left panel.
    • Reboot the device
    • Manually add the wifi adapter in the network section of System Preferences

     

    This seemed to do the trick for me (even with Little Snitch v3.0.2 installed). Only downside is that the OS forgot its name on the network (was set to default), and I had to reconnect to my wifi network again.

    I did a couple of reboots and all looks well (so far).

     

    These adventures are also documented on my blog

    I get that error as well.  It's very frustrating.  I don't have Little Snitch (although it looks like a cool program) so it's unrelated to that.

     

    It happens when resuming from sleep.

     

    If I reboot, then the problem goes away, but it's annoying to have to save all my work locally (no Internet connection) then reboot.  It happens some of the time, but not all of the time.  It's not related to any particular Wi-Fi network or hotspot that I'm near, so I can rule out channels, interference, and so on.

     

    About 10 times a second, this message appears, over and over, in Console:

     

    WLAN adapter PCIE config space was not restored (stateNumber = 2)

    WLAN adapter PCIE config space was not restored (stateNumber = 2)

    WLAN adapter PCIE config space was not restored (stateNumber = 2)

    WLAN adapter PCIE config space was not restored (stateNumber = 2)

    WLAN adapter PCIE config space was not restored (stateNumber = 2)

    WLAN adapter PCIE config space was not restored (stateNumber = 2)

    WLAN adapter PCIE config space was not restored (stateNumber = 2)

    WLAN adapter PCIE config space was not restored (stateNumber = 2)

    WLAN adapter PCIE config space was not restored (stateNumber = 2)

    WLAN adapter PCIE config space was not restored (stateNumber = 2)

     

    This keeps going forever, until I reboot.  It's like something inside the kernel is stuck in an infinite loop.  Because of all this excess logging going on, the Mac becomes slow.

     

    I tried the steps listed in "swithed2mac"'s post just above, and they unfortunately didn't help.  I didn't have many of those plist files anyway.

    Does anybody else have this problem?

     

    Really hoping to find others, maybe there is a solution.

    Just happened again.  Unfortunately, I can confirm that it still happens in 10.8.5 and has not been fixed.

    Not sure if this is the exact same problem, but JAHelms posted a solution that seemed to work for all those that tried it: https://discussions.apple.com/thread/4342982?tstart=0

    Sorry, it's not the same problem.

     

    I can't even get to the network list.  It's not a problem with my network or my router!

     

    It's at a lower level: the Mac is having trouble reactivating the PCIE wireless card.  It can't see the network list at all, because the card never gets turned back on after sleep.  I never get the chance to pick a network, add a network, or anything like that.  It's a fundamental problem below the level of the network itself.

     

    Other computers can see the network just fine.

     

    I have the same problem "alexander110" has.

     

    Any other suggestions?

    Am I really the only one?

     

    Still happens as of OS X 10.8.5.

     

    Does this problem happen to anybody else, or am I truly alone in the world, with such a unique situation that nobody has the answers?

  • 9. Re: Wi-Fi gets randomly turned off

    I have the problem as well. Also still with the latest 10.8.5 version of the OS.

    The problem doesn't occur that often, and since I recognize it pretty quick nowadays I can fix it also pretty quick (remove the adapters, reboot, add the adapters).

  • 10. Re: Wi-Fi gets randomly turned off
    Krellan Level 1 Level 1 (0 points)

    I have the problem happen much more often.  It's happening every few days now.  It just happened again today.

     

    Are you using external wireless adapters?  I'm just using the Macbook Pro's built-in AirPort adapter, which is not easy to just casually remove and reinsert.

    Sadly, this problem still happens in Mavericks.

     

    I upgraded to a new HD.  Took the opportunity to do a clean reinstallation, not an upgrade or restoration.  So, I can rule out any software change I made in the past.  The problem just started happening, within less than a day of doing the reinstallation.

     

    I'm running Mac OS 10.9.2 (Mavericks).

     

    Has anybody else made progress solving this issue?
