Q: Wifi not working after sleep ?

Dears,

I have MacBook Pro (Retina, 15-inch, Mid 2014) with Yosemite 10.10.3 installed

 

I have a problem which is really frustrating !!!!

 

a lot of times we my Mac goes to sleep and then I wake it up again and try to re-connect to Wifi it can't

and then I need to do a restart just to get it working again !

 

I tried to deleted saved connections and to turn off the wifi and turn it back on again but no hope

 

I have all of my apps open and files and everything and then I just need to restart everything just to fix this problem

 

and after doing some research it seems like this is an ancient issue with Mac !! then why it wasn't fixed at all ?

 

So please guys do you have any solutions ?

 

Thanks.

MacBook Pro with Retina display, OS X Yosemite (10.10.3)

    Have you tried deleting the file Library/Preferences/com.apple.Bluetooth.plist ?

     

    Yes, I know you have a WiFi issue but this should fix it. Just save a copy to the desktop incase id doesn't.

    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

    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.

    I tried some of what you mentioned here but it still didn't work
    I didn't try any solution which requires restart cause then I won't know if it was fixed or not

    Hope we get an official fix soon

    Try changing your wifi password. This worked for me. I believe it clears out some cache somewhere and things started behaving normally again.
