Q: MBP wireless not connecting when awaking from sleep

My MBP is running 10.9.2 and recently (6-8 months ago roughly) started exhibiting the following symptons:

 

-Under normal conditions, it is connected to my preferred wireless network.

-If it goes unused for an undetermined amount of time (left alone or closed by the user), when opened/awaken, it cannot find my wireless network

-To connect, I have to click on the wireless symbol on the tool bar and turn wireless "off", wait about 10 seconds and then turn it back on

-Only then does it find my preferred network and allow network connectivity

 

If I leave it alone to search for my network, it cannot find it and remains disconnected.  I know my wireless signal is fine as my Apple TV, iPhone and wireless printer are all continually connected without issue.  The issue seems to have started around the time of an OS update but I am hoping to either find a fix OR determine that a genius bar appointment will fix the issue.

 

Any help is appreciated

MacBook Pro (Retina, Mid 2012), OS X Mavericks (10.9.2)

A:

Test after taking each of the following steps that you haven't already tried. Back up all data before making any changes.

1. Make sure the network is on the preferred list by following these instructions. It's important to read the article carefully, as it's the starting point for any further efforts to solve the problem. If you skip any of the steps, the problem may not be solved. Make sure the box marked

Remember networks this computer has joined

is checked.

2. Follow the instructions in this support article under the heading

Symptom: After restarting or waking from sleep, my computer might not connect to the Internet

10.er pane in System Preferences. If necessary, click the padlock icon in the lower left corner to unlock the settings. Enter your administrator login password when prompted.

Select the Power Adapter tab and uncheck the boxes marked

Wake for Wi-Fi network access

and

Enable Power Nap...

if present. Then, if the computer has a battery, select the Battery tab and uncheck

Enable Power Nap...

3. Reset the PRAM.

4. Make a note of all your settings for Wi-Fi in the Network preference pane, then delete the connection from the connection list and recreate it with the same settings. You do this by clicking the plus-sign icon below the connection list, and selecting Wi-Fi as the interface in the sheet that opens. Select Join other network from the Network Name menu, then select your network. Enter the password when prompted and save it in the keychain.

5. From the Location menu at the top of the Network preference pane, select Edit Locations. A sheet will drop down. Click the plus-sign button to create a new location. Give it any name you want. In the new location, set up the Wi-Fi service with the same settings you used before. Click Apply and test.

6. Launch the Keychain Access application. Search for and delete all AirPort network password items that refer to the network. Make a note of the password first.

7. Repair permissions on the startup volume.

8. Turn off Bluetooth and test.

9. Reset the System Management Controller.

10. This step shouldn't be necessary, but has been advised by Apple Support in some cases, apparently as a workaround for a bug. Open the Energy Saver pane in System Preferences. If applicable, click the padlock icon in the lower left corner to unlock the settings. Enter your administrator login password when prompted.

Select the Power Adapter tab and uncheck the boxes marked

Wake for Wi-Fi network access

and

Enable Power Nap...

if present. Then, if the computer is a MacBook, select the Battery tab and uncheck

Enable Power Nap...

11. Reinstall OS X.

    thank you....I tried a few of the top items but what seemed to have helped in the end was turning off bluetooth.

    Yes, for me also, turning off bluetooth makes an incredible difference to Wifi speeds. From close to nothing, litterally Kb, to itunes match streaming, general Safari activity at a speed I have never seen or heard of before. Truly Amazing. However, I use bluetooth for music, additional keyboard and trackpad. I still have to log out of, then back into Wifi the majority of times after closing the lid (13" Retina MBP late 2013),

     

    Support have been great over the phone on a number of occasions, and when I returned my second machine on Tuesday the Geniuses were amazing, trying so many things, eventually they seemed to have solved the problem, but similar fixes from support worked for a while before the same problems retuned, so I exchanged for another new model.

     

    I am now on my 3rd and this machine is doing exactly the same thing as the 2 before it. Frankly, Im worn out. All my other devices, both current and historicaly worked perfectly under the same conditions. I really need a machine for business, Adobe CC and various apps used constantly with different clients means I close the lid 20 times a day.
