Q: Wifi doesn't connect after sleep and/or no response to clicks from trackpad

My setup:

 

2012 Macbook Pro

2.3ghz i7

16gb DDR3

500gb HD

OSX Mavericks 10.9.2 (13C64)

 

Basically I updated with the latest security patch and all of a sudden:

 

1. Everytime my Macbook Pro goes to sleep and I wake it up, it cannot find my wifi network (this happens at home and in cafes)

 

2. Frequently (2-3X daily) my Macbook Pro no longer responds to input from the trackpad or my bluetooth trackpad.  They keyboard still works. 

 

Any ideas other than turning my bluetooth and wifi off and on.  It worked fine before the update. 

 

Please Help.  My warranty expired and the nearest Apple Store is 30+ minutes away

MacBook Pro, OS X Mavericks (10.9.2), Macbook , iPad, iPhone, iPod Touch, iPod Classic

    Hi Ariel Nava,

     

    Thanks for visiting Apple Support Communities.

     

    If your Wi-Fi and trackpads are intermittently not responding, start by resetting the SMC on your MacBook Pro:

     

    Intel-based Macs: Resetting the System Management Controller (SMC)

    http://support.apple.com/kb/HT3964

    Resetting the SMC on portables with a battery you should not remove on your own

     

    Note: Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).

     

    1. Shut down the computer.

    2. Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.

    3. On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.

    4. Release all the keys and the power button at the same time.

    5. Press the power button to turn on the computer.

     

    Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

    If the behavior continues, you may find these articles helpful:

    So that did not work.  I have seen several discussions about this issue.  It has only been during the past 3 or 4 months that this has been happening. 

     

    The computer wakes up, but doesn't always see the available networks.  At some point it sees my network, but I cannot connect.  Usually I have to turn the wifi on and off to get it to both recognize and connect to my airport network.

    I found this recommendation on a site called "imore dot com".  I won't try to link to it since I think Apple prevents that.

     

    Summary: corrupt Bluetooth plist file can cause the problem.  Remove the bluetooth plist file.

     

    It worked for me.  I came here because I was very frustrated with the no-wifi-after-sleep problem that many other people report.

     

    Here are the steps that fixed it for me:

    • Go to your Mac's Finder.
    • Click on the File menu and select New Finder Window
    • Click on your Mac's icon in the Devices list in the sidebar
    • Open Macintosh HD (or whatever your Mac's hard drive may be named)
    • Open Library
    • Open Preferences
    • Find the file called "com.apple.Bluetooth.plist"
    • Move it to your desktop. It should copy there.
    • Remove it from the Preferences folder by dragging it into the Trash. The Mac will tell you that Finder wants to make changes. Type your password to allow this.
    • Restart your Mac.

    Try running the combo update. Supposedly Apple fixed this problem.

     

    10.9.4 Combo Update

     

    I won't try to link to it since I think Apple prevents that

     

    Apple normally doesn't block links. I, and others, use them all the time.

    Interesting timing.  My system update hadn't picked this up yet, but I hope

    it fixes several issues I've been having.

     

    Thanks!
