Q: OSX Yosemite Wifi issues

Hi there,

 

I upgraded my Macbook Pro Retina 15" (mid 2014 revision) to OS X Yosemite last night and am now having issues when using my home WiFi connection. Whilst it connects to either the 5Ghz or 2.4Ghz network, it is basically unusable. Web pages take minutes to load (if they even load at all), dropbox doesn't sync because it can't get a connection and even trying to get to the router config page is extremely slow and hit/miss.

 

Tethering to my iPhone seems to work ok, as does using my home network via wired ethernet.

 

Are any others having problems with Yosemite? Wifi was working fine on Mavericks.

 

Tom

MacBook Pro with Retina display, OS X Yosemite (10.10)

    Nope, although it hasn't disconnected, the speed is atrocious - cannot get better than an average of 8MB/s with the occasional peek of 22mb/s.

     

    This is on Wireless A/C

    JJust Downloaded and installed with working network. After update nothing works. Can't connect to web at all. no tricks are working. For me, 10.10.01 is worse than 10.10.

     

    WRiting from iphone as Mac can't connect at all. I will have to go back to troubleshooting fantastic

    I had that to start with, had to turn wi-fi off and on a couple of times, then it connected to the router.

     

    Think I'll be reverting back to Mavericks this week at some point.

    So - I am back online - after doing the routine fixes that I have been doing the past 2 months..

     

    This is my installation Experience

     

    1) Downloaded the update in less than 2 minutes

    2) During installation, I was given the log in screen. I entered credentials and the installer came back, stating it needed  7 more minutes. Then after 10 seconds, my desktop was there and I was running 10.10.01 official release.

    3) The first thing I noticed that I was connected to my WLAN and that I had ZERO internet Connection. My console was overflowing with the same messages it always overflows with when the issue occurs.

    4) I ran the usual suspects... Incl.. safe boot, SMC Reset and NVRAM reset. NO Internet.

    5) I restored my Airport Extreme to Factory Defaults and created a new WLAN along with a new Network Location. Rebooted and now I am online. Again.

    Latter (Point Number 5) was the only thing providing a remedy.

     

    Lets see how long this will last...

     

    Anyway, 10.10.01 does NOT fix the WIFI issues. I had to go thru the same extreme routines I have had to go thru' the past 2 months to be able to connect to the internet.

     

    This is not a very good sign. Because this indicates that no one has been able to reproduce a clear-cut scenario in which this happens. So we are back to square one...

    To anyone with issues after 10.10.01

     

    Try Resetting the Airport Extreme or other router - to factory defaults. See your documentation on how to accomplish that. NOT just a reset.

    Then Create a brand-new WLAN Network

    Then from network settings create a new Location and apply that.

     

    That did it for me !

    That's all well and good, but not everybody has an Airport Extreme.

     

    Infact most of the people I know use the ISP provided WiFi router.

     

    Or have business grade Meraki or Cisco - these are working fine with every other version, except Yosemite 10.10.1 - even windows works flawlessly

    Then those folks should try to reset those to Factory Defaults....

     

    Not saying it should not work out the box... But clearly this problem is bigger than anyone thought !

    Sadly in a real-world it's not viable to reset all the devices, especially the business grade APs, for example Meraki APs which are cloud configured, the Cisco Aironet APs are controller based.

     

    Also, if the configuration works for everything else without problems, then it's 100% Yosemite that's the root cause of the issue.

     

    I've been looking through the logs on the Cisco APs, and there is nothing to indicate any problems at all, apart from indications of the Yosemite device "going away"

     

    I've got Windows machine with Windows 8.1 and wireless A/C, that works fine, I've also got a Mavericks MacBook Pro, and that works fine, as does the Mavericks iMac - the only machine that's having problems is the identical hardware MacBook Pro, which has Yosemite. - all of these are connected to a Cisco 3702i in Autonomous mode (No need for a controller).

    We've got business grade routers and APs at my school, and we've got numerous people unable to connect for longer than a minute before and after to 10.10.1.

    I strongly suggest that anyone having issues send feedback to Apple about it.

     

    It is quite obvious with this new update that they did not have any clear-cut repro case which would reliably trigger those devious events.

    Before installing Yosemite, I cloned my Mavericks install to an external USB drive

    if I boot on that, the Wifi issues disappear, proving it's not the hardware but Yosemite

     

    Additionally, If I turn off wifi, then turn it back on, my Wifi speed restores to maximum and stays there until I do something silly like click on airdrop

    (I had my SSID details displayed by alt-clicking the Wifi option, then went to Airdrop in Finder .. the speed immediately dropped)

     

    One more note, run up something like Wifi Explorer .. and watch 2.4Ghz SSID's randomly disappear for a while and return. This never happened under Mavericks

    and is verifiable on another device (e.g. PC) as a Yosemite only issue

    I have a mavericks partition on a separate hard drive. It does not once drop internet connection. The bug is within Yosemite.

    10.10.1 didn't fix my wi-fi issues, still randomly dropping every few mins or so!

    It didn't seem to have fixed my wifi issues, either. For well over an hour after installation, it worked great on the automatic settings - until it didn't.

    Just switched to the manual settings (manual DNS + hardware settings, one of the many "fixes" suggested which had assured that I'd be able to stay connected for varying amounts of time,) I'll see how long this lasts...

    All in all, unfortunately, 10.10.1 doesn't seem to provide a real fix on my mid-2012 MBP.
