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)

    GUYS!!

    I think this actually works!!, it has been letting my wifi run for over 7 minutes (if it disconnects i'll reply in a new post.

     

    Try This:

     

    "

    Guys, I have a Macbook 2008 Unibody, upgrading to Yosemite killed my wifi too. Cannot turn it on at all, and it was stuck "off".

     

    None of the solutions so far in thread worked (clearing PRAM, deleting configuration folders etc. Did nothing).

     

    But I fixed it, heres how:

     

    1. Open Network Preferences, click once on the WiFi adapter in the list there on the left. Then click the little cog icon at the bottom and select "Make Service Inactive". Click APPLY.

    2. Then click on the WiFi in the same list there again, and then click the - button to delete it. Click APPLY.

    3. Reboot the Mac.

    4. Once rebooted, go back into the Network Prefs, and under the network adapter list click the + button, and then in the dropdown list (which is probably showing Bluetooth by default) select WiFi. For the name field, change it from WiFi to WiFi2. It's important you add something to the name here (I've just suggested to add a number 2), or else it will break again on next reboot. Click APPLY.

     

    You should then have a working WiFi, that survives reboots.  "


    Hope it works!

    I was looking in another Yosemite WiFi thread (OSX Yosemite Wifi issues) and I found this solution posed by user mamaricci

     

    "I just tried something, which so far seems to be working. Go in to your Keychain access - System. Find your wireless network - double click. There are two tabs, Attributes & Access Control. Go into the Access Control and check "allow all applications to access this item". Mine was defaulted on confirm before allowing access, which I think was knocking me off every time I tried to do anything."

     

    This solution has worked for me!!!!!!!!! I am so happy right now. I have been consistently connected for 26 minutes when I usually couldn't stay connected for even 3 minutes. I also created a new network location in Network Preferences called Internet. I'm not sure if that helped, but I did it.

    HI!! I tried this and the other option and it only lasted around 28 minutes. Non of these solutions are permanent. This is an issue that apple has to work out NOW.

    Can confirm. No more than 10 minutes later, the same problems started back up while browsing the App Store. I am so far at my wits end. I can't even contact support because my "coverage has expired." Seriously what an oversight. How could they possibly release a GM when there is this blaring WiFi problem. We are not the only ones! I am so ashamed of Apple right now. I have been a user since 10.7 Lion and have NEVER had any issues like this. Let alone the fact that everything worked fine back in Developer Preview 1-3.

    I am having similar wifi problems on my new 15" MBP with Retina display. My wifi at home works fine (WPA2 personal) but my wifi at work constantly loses connection (WPA2 enterprise).

     

    This problem started when I installed the Yosemite beta about a month ago, I waited for an update to the beta but the next update didn't fix it so I reinstalled Mavericks on my machine, and have had no problems for the last month. Yesterday I installed the final Yosemite release through the App Store and now it is happening again. This definitely seems to be a bug with Yosemite and needs to be fixed.

    What is very misleading is how many people come on this thread and say "THIS ONE WORKED FOR ME!!!" when they probably haven't given the solution any amount of time to fail.

     

    All of these posted solutions have worked for at least an hour or two, some longer.  But ultimately they have all failed in the end.

     

    This bug has been present since the first beta, although it is relatively better, it still persists in the released version.

     

    The only solution that has provided me with the longest time on wifi is changing to a 2.4Ghz network.

    Hi

    Duplicating a new service in networks and disabling the first one has worked for me over the last 2 days using a number of different wifi networks at home, work and out and about.  I did at one point think that using my MBP on battery was also adding to the problem, but that has not been the case in the last day and a half.  

    I'm sorry this has not fixed your problem but please do not make wide ranging statements questioning other people's honesty saying they have the problem fixed on this thread without hard evidence.

    Wide ranging? Really?

     

    I'm not questioning anyone's honesty.  I am questioning their troubleshooting skills.  It's super easy to say that it is resolved just because superficially, it is.

     

    If you haven't stayed on the same SSID for at least 24 hours, without shutting down or sleeping your Mac, you haven't thoroughly vetted your solution.

     

    I challenge everyone here who has had success with their reported solution to do this, then return and report to the group here and state what solution worked for them.

    Thanks for the suggestions, unfortunately nothings worked for me.

     

    I have an iMac (20-inch, Early 2009) and a MacBook Aluminium Unibody, both of which are now not connecting to wifi but did before the Yosemite update.

     

    This makes me really quite angry as I'm and Apple beta tester and reported this problem a month ago and was hoping they had fixed it for final release. Apparently filling in all the feedback forms if pointless because they don't action them.

     

    Well done Apple! I think we can call this a complete failure! Or rather ANOTHER complete failure!

    This same solution worked back in Snow Leopard. However, it did not work for me this time. The only thing(s) that appeared to have worked was to switch to manual IP, disable the firewall, switch back to DHCP, and re-enable the firewall.

    Just a quick comment:

     

    It would really help if people who post about problems with Wi-Fi described the wi-fi system they are connected to. (WEP, WPA2 Personal, Enterprise (and what subprotocol such as LEAP EAP-TLS etc - Pressing ALT when clicking on the wi-fi icon on menu fbar gives you details of how your computer connects to the wi-fi network.

     

    If a trend comes out with problems happening only on certain types of connections, then it would help make formal bug reports to that now alien company in a spaceship landed in Cupertino.

    I have same issue: intermittent wi-fi "disconnects" (though looks more like DNS lookup failures to me) and have tried everything from deleting SystemConfiguration files, to resetting PRAM and SCM, and more... Even reinstalled Yosemite twice.

    I just got off the phone with Apple Support (a senior support engineer) who said mine was the 2nd intermittent wi-fi issues report she personally had dealt with today and that she had heard of many more Yosemite wi-fi incidents being reported at Apple Stores. I was told that they don't have a fix for this and that this is likely an OS bug that is being escalated to engineers (or so I was told).

    If anyone finds a fix that really lasts (i.e. more than 24 hours, on multiple SSIDs, after sleeps etc etc) it would be great to know.
