Hi ..

 

Might be corrupted network preferences as a result of the upgrading.

 

 

Open the Finder. From the Finder menu bar click Go > Go to Folder

 

Type or copy paste the following:

 

/Library/Preferences/SystemConfiguration

 

Click Go then move all the files in the SystemConfiguration folder to the Trash.

 

Restart your Mac.

 

 

See if that makes a difference.

 

Your Mac will generate a new SystemConfiguration folder for you.

 

If that doesn’t help, try here >  Wi-Fi: How to troubleshoot Wi-Fi connectivity

    Having upgraded to 10.10.4 and after a problem solving mission with apple support I think I have found a solution to stop the wifi issues I was having when I upgraded to 10.10.3 

     

    My macbook lost wifi connectivity when i awoke it from sleep mode, so I would have to turn wifi off and back on again to solve the problem.

     

    Apple support performed a lot of tests on my macbook and the one that seems to have worked is a SMC RESET.

     

    Resetting the System Management Controller (SMC) on your Mac - Apple Support

     

    Since i have done this reset, my wifi connectivity seems to be fine. I had previously tried system cache resets, checking my disk permissions for errors, checking my icloud integration, face time settings etc etc but nothing seemed to work.

     

    I hope some of you may find this useful as I have tried every suggested fix in these forums and nothing helped.

    That makes a lot of sense. I have a home configuration using Airport, and have no problems with my new MBP 13 Retina. But at our lake house with the cable company-provided router, I have constant dropping of the wifi. I created new locations and reentered the DNS, and it works for a while then stops working. I am not at the lake anymore, but if the problem is there again next Spring I will be back at this thread.
