Q: Yosemite (OS X 10.10) killed my WiFi :(

I just updated to Yosemite on a brand new 15" MBP Retina Display. For some reason my WiFi is not working. I turn it on and select the network I want to join (my regular network at home that I've been using with this same computer before updating). So, I turn it on and select the network and doesn't seem to want to join it and then my WiFi switches back off completely.

 

Is anyone else having problems with their WiFi on Yosemite?

MacBook Pro (Retina, 15-inch, Mid 2014), OS X Yosemite (10.10)

    Removing the bluetooth.plist file did the trick for me. In my case bluetooth clearly was the issue though : i could ran a torrent download and see the rate drop as soon as i clicked "activate bluetooth" in my preference pane, and raise up again immediately after deactivating it.

    Thanks.

    Wifi issue fixed / solved thanks for Nicknish #1 point:

     

    I have a MacBook Pro 2012 Retina. Tried the Bluetooth and Preferences file, did not work. Deleting the Wifi and renaming to Wifi2 did fix the issue. Now I can start working again!

     

    Thanks!

     

    1. Creating a New Wi-Fi Service (this solution worked for me!)
      • Copy and paste these instructions, because you'll be disconnected from the Internet and you'll need to reboot.
      • Go into your Network Preferences > Select Wi-Fi Service (in the list in the left column) > Click on the options (cog icon) > Select "Make Service Inactive" > Select Apply.
      • Select the same Wi-Fi Service > Delete It ( – ). Reboot.
      • Return to Network Preferences > Create a New Service ( + ).
      • Inside the prompt select Wi-Fi under Interface, name the Service Name something other than Wi-Fi. (I named mine Wi-Fi2. Apparently if you retain the previous Wi-Fi name the WiFi dropping will return on reboot.) > Click Create.
      • Click Apply.

    Like with IOS-8, Apple disabled LEAP (and possibly others) for Wi-Fi connection in Yosemite AND removed

    the ability to enable it in System Preferences->Network->Advanced->802.1X

     

    You need to download the Apple Configuration Utility from the App Store, and generate a .mobileconfig file that contains a Wi-Fi config that enables all protocols. I had to specify my usename/password to make it stop complaining even though the text implies you can leave it blank to force user to specify on target machine.

     

    Getting to the place where you create a Wi-Fi profile and can then export it as a file is not obvious and I totally forgot how I got to it. There is another area where you can specify Wi-Fi profiles but tyou can't export it, it expects to have connected USB devices.

     

    Once you have the .mobileconfig file,  drag it over the open Network->Advanced->802.1X panel and it gets loaded and you will find your wi-fil will once again be enabled.

    I fixed mine with one little move. And boy I didn't see that coming. After two days off pulling out my hair, listening to my daughter complain and reading and re-reading what everyone has tried. I tried them all and was getting nowhere. Who knew it was unplug the surge protector and plug it back in. I'm going to explain this the best way I can because some of you may have the same set-up and not even realize it. It has to do with my carrier. I had Qwest which is now CenturyLink. When Qwest set-up my system they use a surge protector with an ethernet cord that is plugged into the wireless modem/router.

    After running diagnostic on it multiple time it would ask is there anything else plugged into the router. Finally, I realized that the surge protector is plugged into the router. I unplugged it the surge protector from the wall and plugged it back in. Everything worked! My daughter's iPad starting going crazy and everything started working perfectly. Who knew it was unplug the surge protector and plug it back in.

     

    I hope in some way this helps other out there.

    i have two macbook pro retina's. my personal one has me as the admin.

     

    my 2nd one, has my daughter as a "parental controlled" account. her wifi was not working. changed it to admin - wifi started working.

     

    changed her to a standard user but unchecking "let user admin this computer" - wifi also works.

     

    this is some weird permissions thing in the keychain...

    One of the reasons I hate OS X and iOS updates is that the *always* have wifi and/or bluetooth problems..
