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)

    HAve you tried using another DNS? OpenDNS or Google's?

    Yes - using Google's 8.8.8.8 and 8.8.4.4

    Big bug but check if the account you are on it the computer administrator. If it is not, the wifi will not work, at least for me. You can go to system preferences-Users & Groups and change who the admin is. This completely worked for me. Hopefully this helped. This is just red to get your attention.

    This fix (adding a new wifi service to the network preferences) seems to work (1 hour) and bluetooth (keyboard and trackpad) both work.

    The wifi menu at the top for control panel/preferences has wifi 'x'ed out, but wifi works in all apps.

    Applied the recommended steps and it solved the problem with my iMac.

    I have gone from less than 1 MBPs back up to 35 MBPs.

    Same issue here with 2013 MBP 13in. Bluetooth off does not help. I don't see creating a new network location as an option. Will await a reply from Apple but may have to downgrade. I manage hundreds of Macs at my school and will not recommend anyone upgrade to Yosemite yet.

    Why not, it takes about 2 minutes and usually works?

    Also, under network preference I had previously felt compelled to check (under advanced click) remmber networks which was left unchecked after updating from Mavericks, FYI.

    Thanks for that.

    I've tried all your suggestions, with no real improvement. I also tried disabling bluetooth and handoff, which helped for a while, but then the problem came back.

    I also tried changing channels on the router. No luck.

     

    In my case it sometimes works for for 10 minutes (however ping times vary significantly) and then loses the connection. Sometimes pings will stay normal - 20ms to 8.8.8.8, but Safari, Chrome or any other app will not connect.

    I have full signal bar at all times. Other devices on the network - iPhone, old Thinkpad PC, iPad, all work perfectly fine at all times.

     

    I had Mavericks and Yosemite public beta running on separate partitions. Mavericks was always perfect, Yosemite had this problem from the beginning.

    I upgraded Mavericks to Yosemite on the day it came out believing that the problem was related to beta or my particular installation.

    I was wrong. It seems it is a Yosemite related issue.

    This solution worked for me! Thanks so much.

     

    Try setting yourself as admin for the Macbook (for some reason I messed with these settings last year, and wasn't admin), and my wifi is back, even after reboot, which is when the other solutions stopped working before, so I'm thinking this solution might be it!

     

    Also, just for reference:

    I was troubleshooting with Apple Phone Support (downloading Yosemite entitles you to 90 days of complimentary phone service, fyi) for 3 hours on Sunday night, and we tried the following:

    -Setting a new location for Wifi: Network Preferences > Location dropdown (says Automatic) > Edit Locations > '+' to make a new location > Name it whatever > back to network preferences > click clog symbol on bottom left > 'Set service order...' > make sure WiFi is first on list.

    >> this solution worked for about 4 hours, until I shut down my MBP and the problem persisted after that.

    -2nd troubleshoot idea from phone support: Re-install Yosemite -- Shutdown MBP > Start it up while holding Command + R (this accesses the recovery partition) > let go of CMD + R when you hear the start up sound > when Recovery Window starts up, select the option to re-instal OS X (make sure it says 10.10) then just follow the prompts.

     

    These two solutions weren't lasting, that is until I set myself as admin. So if this helps one of you, then I'm glad.

    I having the same problem with a WPA2 Enterprise, 802.11ac network at the university where I work. I've tried all the fixes and nothing sticks.  At the same time, I'm having no problems with two different 802.11n networks from an Airport Extreme and Airport Express (WPA2 Personal in both cases).

     

    I had zero problems with Mavericks on a 2014, 13-inch, retina Macbook Pro.

    I've had nothing but wi fi problems since updating my 2012 macbook pro retina 15". This has been one of the most frustrating updates by Apple in recent memory. If the problems persist through tomorrow, I'll be reverting back to Mavericks.

    First it was iOS 8 killing Bluetooth car kits in a wide range of vehicle makes/models, rendering my iPhone 6 useless in my new car. 

     

    Now they have destroyed my MacBook Pro retina with this issue.

     

    Seriously, *** is going on in the background at apple that is turning everything to a steaming pile of crap.  Didn't all their stuff "just work" in the old days, which is why we all agreed to pay more for quality?

    After disabling all plugins in Safari, doing the two preferences check boxes and running fsck -fy, in terminal (single user)...everything seems fine now.

     

    Awesome.
