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)

    I haven't been able to get a connection to my 802.11ac network since upgrading to Mac OS X Yosemite. If I run Mac OS X Mavericks or Linux I have *no problems whatsoever*, but I cannot get Yosemite to associate to the network:

    My machine has been fixed after I did the instructions in the link below.  This is a mid 2009 MacBook Pro that has been updated for each OS, so it's never had a clean install since I first got it.  I knew a clean install would be best and after the wifi trouble I gave in and did it, assuming it would be a total PITA.  The link here was very easy to follow and I was able to do a nice clean install and recover apps and data from Time Machine as the last part of the installation.  Didn't even need to do all that USB boot drive stuff either.  Almost happy this happened now and will do this for all future updates.

    It would be nice if those hawking their wares did not attempt to prey on those of us saddled with this problem by attempting to sell us useless software that will not solve this problem.

    I stand corrected.  This has not corrected the problem.  Wifi still unstable.

    Everything is fine only if I VPN into my work network. Disconnect from VPN and the wifi becomes a worthless brick again. I believe wifi at my work seems to be working fine too although I'm not onsite at work to verify it for long periods of time.

    Hi,

     

    iMac27" mid2011

     

    1st) my wifi router runs perfectly for the rest of devices (imac2008 with mavericks, iphone4, iphone 5s, ipad...).

    so i don't know why to change anything in the router

     

    2nd) I tried resetting SMC, and everything posted here (keychain....)

     

    3rd) I did a clean install : wasting time

     

    And the worst is that Apple don't say a single word like : "sorry for the inconvenience, we are working on update. Expected release xx days" or something like that.

    It doesn't matter so much that a company has made a mistake, released a bug etc.

     

    It's more important on how the company deals with that mistake.

     

    In the case of Apple, their customer relations over this problem leads a lot to be desired.

    Why don't I or anyone I know have this problem, are there two versions of Yosemite, one with a bug and one without?

    Hi,

    I had the issue for a few days on a mba 2012. I tried all the fixes I could find and noticed that switching my laptop to a different router made the issue disappear. I then checked the settings on both routers and spotted a difference in the security settings. Setting AES instead of TKIP for encryption method seems to have solved the issue using the original router (the one that kept on causing drop outs). My settings are WPA2-PSK with AES.

    I hope this helps.

    cheers

    You are on to something! Although I have the issue with WPA2-PSK with AES but I have no issue when i enabled a guest network without security.

    A few more tests revealed that if I don't force either WPA nor WPA2 (so leaving it in "auto WPA/WPA2 Personal" in my router - not sure if all routers support this) and with AES make a very stable connection. When I forced a WPA2+AES the connection was unstable...

    OK, by way of further update, with so many users having problems with 802.1x EAP-TLS type connections, I did a new install of OS X 10.10 Yosemite, from USB to a back-up hard disk, and that works fine.  So it would appear not to be the box (MacBook Pro Retina mid-2012), but something to do with the fact the install went on top of OS X 10.9.5 (Mavericks), or some other aspect of the box.  Since the problem is pretty common in our corporate environment, I'd say it is likely the migration path to Yosemite.

     

    I think this is one Apple will have to likely fix.

    I   I've had the same problems, and just today it got even weirder.  Now I have an "X" in the WiFi icon at the top ribbon.  This morning, thinking I had nothing to lose, I basically went directly to step #4 and even though the "X" remains, I have a WiFi connection that's been working fine.  There are a lot of things I don't like about Yosemite (design is a big one - middle school-level graphics), but the WiFi connection problem is the most unconscionable of all.  I have similar issues with iOS 8 and wish I could just go back to the previous system - I'm experiencing touchscreen delays and a lot of unintended window jumping that causes extra time to do most tasks.  What's happening at Apple???
