I have a Macbook Pro with Mountain Lion v. 10.8.4 and it will not automatically connect to wifi after waking from sleep. Any advice I've tried everything I've seen already anything new that might help.


Thank you,

    Is the network listed as a Preferred Network in the Network preference pane, and if so, do you have the same problem with other preferred networks?

    Are there any other preferred networks, and if so, do you have the same problem with them?

    Back up all data before making any changes.
    Step 1
    Take all the applicable steps in this support article.
    Step 2
    If you're running OS X 10.8.4 or later, run Wireless Diagnostics and take the remedial steps suggested in the summary that appears, if any. The program also generates a large file of information about your system, which would be used by Apple Engineering in case of a support incident. Don't post the contents here.

    Step 3

    If you're not using a wireless keyboard or trackpad, disable Bluetooth by selecting Turn Bluetooth Off from the menu with the Bluetooth icon. If you don't have that menu, open the Bluetooth preference pane in System Preferences and check the box marked Show Bluetooth in menu bar. Test. Continue if you find that Wi-Fi is faster with Bluetooth disabled.

    From that same menu, select Open Bluetooth Preferences. If the box labeled Discoverable is checked, uncheck it. Click the Advanced button, and in the sheet that opens, uncheck the top three boxes, if any are checked. Click OK. Enable Bluetooth and test again.

    If the application called "Bluetooth Setup Assistant" is running, quit it.

    Step 4

    This step will erase all your settings in the Network preference pane. Make a note of them before you begin, and recreate them afterwards. It may be helpful to take screenshots of the preference pane.

    Triple-click the line below on this page to select it:


    Right-click or control-click the highlighted line and select

    Services Reveal

    from the contextual menu.* A folder should open with an item named "SystemConfiguration" selected. Move the selected item to the Trash. You may be prompted for your administrator password.

    *If you don't see the contextual menu item, copy the selected text to the Clipboard (command-C). In the Finder, select

    Go Go to Folder...

    from the menu bar, paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return.

    Reset the System Management Controller.

    Hi ARMartinez0984USN,


    I recently had the same issue you were having where my computer would force me to manually select my preferred network.  I found your thread and read a few other articles online and was able to fix the problem.  I hope you have solved the issue by now, but if not this article helped me:


    Essentially all I had to do was delete my network from the preferred networks list and then ad it back.  After this my problem was solved.  Hope this helps with your problem.

    I had the identical issue after upgrade to 10.8.4

    The recommendation to simply delete my network and re-add it didn't work. And the down side of deleting is that you lose all your Network preferences.


    An alternate, less destructive fix that worked for me: add a location, change to that location. Bam. Done.


    >SystemPreferences >Network > Location > Edit Locations +to add a new location, Apply, then Reboot.


    I kept all my preferred networks intact AND solved the issue of Wifi not connectiong automatically.


    Not sure what the root issue is, and that bothers the geek in me, but having lost my Saturday Morning trying different solutions, I'm going to let that sleeping dog lie and be glad it's working. ;-)

    I finally fixed this annoying issue. Here is what I did (I'm not sure which step actually fidex the problem).


    Remove all networks.

    Remove all wifi passwords stored in keychain.

    Re add the network(s).

    (still not connecting after waking up from sleep at this point)

    Update OS to latest version 10.8.4



    Bazinga it WORKS!!!

  • kkulkarni Calculating status...

    I had tried deleting and the network several times before, to no avail.


    This is what I noticed:

    On the 'Advanced' page where it lists all the networks, notice the entry in the Security column.

    For mine it said 'None', this was even after I had picked WPA2 Personal and added the password several times before.


    Here is what worked:

    I deleted the offending network, while adding the new network selected the security type as "Any (Personal)", entered the password and saved. Now the security type says "Any (Personal)" and the network starts on wake up from sleep

    That was in Step 1 of my comment of July 21.
