Oct 20, 2014 11:56 AM in response to EastyIncby planetdom,Since I upgraded my wifi broadband box to dual band the issues started then I went back to single band and every thing is ok again so there must be a conflict with duel band I live in the uk and use Virgin Media.....I am now using the Virgin Media box as a modem and using my old router as the router...

Oct 20, 2014 1:52 PM in response to Yvantooby tylerforsythe,We have seen the same issue with WPA2 Enterprise PEAP connections. Logs indicate that the clients are jumping between APs every few seconds. It's not clear whether they're being dropped from the network, and then reconnecting to another AP, or simply aggressively roaming.

Oct 20, 2014 4:27 PM in response to tylerforsytheby EastyInc,I can confirm that my issue is related to WPA2 Enterprise (PEAP) wireless environments. At home i use WPA2-PSK and it seems to work fine.
Several clients (plus my own office) use Cisco based WPA2 Enterprise (PEAP) wireless environments and I have encountered the issue at all of them.
Connects fine but disconnects when any sort of load gets put through it.

Oct 22, 2014 2:07 AM in response to EastyIncby puporok,i can confirm the issue too.
My Late 2013 Macbook Pro drops wifi connection on heavy load when i'm connected to WPA2 Enterprise network
At home with AirPort Express all works fine.
The support team diddn't help either.
Just going back to Maverics.

Oct 22, 2014 9:20 AM in response to EastyIncby PinkApps,Confirmed for a 2012 MacBook air on a PEAP(MSCHAPv2) connection. My connection drops after about 10 seconds consistently. Works fine on other connection types.
It was hard enough to even get corporate IT to enable an internal Mac network, now an OSX update makes it unstable. I need a patch, because they won't update their network for sure!

Oct 22, 2014 1:29 PM in response to EastyIncby tylerforsythe,Some of our users have seen improvements by disabling Bonjour. In 10.10, this is performed by:
- Open the file /System/Library/LaunchDaemons/com.apple.discoveryd.plist for editing as root.
- In the "ProgramArguments" array, beneath the line "<string>asl</string>", add the line "<string>--no-multicast</string>" with appropriate indentation.
- Reboot and test.
Please be aware that I have no idea what the broader implications of this may be, other than disabling any Bonjour service, including AirPlay, AirPrint, etc. This may cause other issues. (I've noticed that it makes the menubar Airport signal strength indicator inaccurate, and appears to prevent the automatic joining of networks.) Delete the line and reboot to reverse the change.
Dropping multicast packets at the wireless controller does not seem to help.

Oct 23, 2014 9:09 AM in response to tylerforsytheby Stan in London,This seems to be an issue for me. I find my wifi at my university now unstable and IT finds that I am leaping between two pieces of equipment. Macbook Air 2013 - worked fine with same wifi system until Yosemite update. Seems like a software issue

Oct 26, 2014 6:13 AM in response to EastyIncby EastyInc,I think it's fair enough to say that the problem is widespread and prevalent in multiple makes and models. I'm really disappointed in the way that Apple has handled the issue. Whilst I am sure that they are working tirelessly on an update that will fix the problems, a little bit of acknowledgement wouldnt go astray.
What could they possibly stand to lose by releasing a short statement; "We are aware of an issue im Yosemite which is affecting wifi for some users and we are currently working on a solution."?

Oct 28, 2014 6:10 PM in response to EastyIncby Nexus!$%,I am so disappointed! Does this mean Apple has abandoned old Mac users? This is my one and only one machine, and I do all my school work on it, and its not even connected to the Internet!

Oct 29, 2014 9:37 AM in response to EastyIncby tdilkie,I switched my router from 2.4GHz to 5GHz and that appears to have resolved the issue. No more of those error message on my console.

Dec 23, 2014 3:09 AM in response to tdilkieby LocutusEstBorg,Same problem on my iPhone 5S iOS 8. WPA2 Enterprise repeatedly disconnects and reconnects while WPA2 Personal is stable. I have two SSIDs on my Cisco AP that uses each encryption respectively. I can only stay connected to the WPA2 Personal SSID.
I think enabling "Band Steering" (where the AP won't respond to 2.4 GHz requests if it also receives a 5 GHz request) or simply disabling either 2.4 GHz or 5 GHz is the solution.

Dec 23, 2014 3:15 AM in response to EastyIncby Robocopper,I have been struggling with this dog-turd 10.10.1 for several hours trying to get the wifi to work. It now does, but I may just vent a little by saying that I have had a guts full of Apple putting out overpriced substandard crap like this. I was totally Mac everything for many years but recently both Apple's politics and their nagging legacy and continuation of arrogance has really pushed me outside of the reality distortion field. This is a com pay with billions in the bank yet they a so pathetic that they cannot test their software prior to release. Sure it is hard to find and eradicate all bugs but the number of people having wifi problems is Yosemite is disgraceful and speaks of Apple's incompetence.
For all the other poor suckers out there who have also wasted considerable time (which I'm sure Apple won't pay recompense but would be happy to charge you $$$ to have their agents try to fix it) I will tell you what I did.
First, I went to my wifi and under Network...Advanced and renewed the DHCP, only to find that it was providing an address outside of my network range. So I set the IP4 setting to manual and entered a valid IP address (192.168.1.123 in my case) with subnet mask 255.255.255.0 and router 192.168.1.1, okayed that then Apply, and now the wifi is working again.
**** you Apple. The above and so many other annoyances in recent times are driving me back toward Microsoft. Windows 10 is becoming more appetizing by the day.

Apr 20, 2015 7:35 PM in response to planetdomby watchthinker,I've got the same problem.
Actually I have followed the URL (http://osxdaily.com/2014/10/25/fix-wi-fi-problems-os-x-yosemite/) to reset wireless but failed.
I tried to setup from beginning but seems PEAP authentication is not support in Yosemite.
Is it correct?
