Q: OSX Yosemite Wifi issues

Nicknish's first solution worked for me to.  I had to do this with my Mavericks upgrade at work last year.  The explanation from our help desk was that you have to do it with what ever wifi network you conduct the upgrade over.  I image some settings don't get reset since they were active/locked during the upgrade.  My wife and I were dropping every 5 to 15 minutes and now we've been solid for about 2 hours.  I'll report back here if that changes ; )

Also, I noticed that those that said this didn't work for them said they changed their network 'location' not recreating their WiFi interface.  Totally different things.  Delete your Wi-Fi interface using the minus button at the bottom of the interface listing.

Yes, a very irritating bug.

I will say that I have been so spoiled over the years with my Apple products and how they "just work", but I am not as enchanted as I once was......:( I hope they turn it around soon....that said, I can say with 100% certainly, that I will never return to a windows environment...EVER.

Exactly. Sometimes I find myself bickering over something. Then I realize that Apple has infected me with Luxury.

Here in Germany, they have a monster of an electronic store called Saturn. I visit it approx. once per month. And not once do I visit this store without checking up on the competition like Samsung. The minute I get the Galaxy in the hand, I'm like nice. Not much of a difference to the iPhone... Then I start browsing about and use the device.... A minute perhaps two.. The feel of the software and OS is so low-quality compared to iOS. And that is when I know that been luxuriated by Apple...

I am a beta  tester (At heart as well) for a lot of companies.... I a have seen a lot of bugs and strange beta version across the years. The beta versions are there for a number of reasons and they have non-optimised code etc. in them for a number of reasons... As nervy and nasty as a release can be, I don't think it is good practice to begin discussing Beta software on a public forum. It is not fair either. Neither to Apple nor to the Users. 10.10.01 is the first beta cycle and a beta cycle seldomly lasts for 'one' cycle. But have numerous iterations. And for a beta tester to come here and state that the wifi bug isn't fixed in the first cycle is something that beta tester should be reporting to the Apple Team and NOT to the general public. He can do that once the beta has become an official release.

The more beta testers, reporting reliable repro-cases to Apple the better the general public releases will become. 12 years ago I was very very active on public forums, complaining about bugs. It never helped. So I decided to become beta tester for software which I use a lot and put in my forum-time where it really matters.. Proper Bug Reporting helping me and the developers ;-)

I went several pages back and couldn't find "nicknish" post. Can you please disclose details of his solution and how did you applied it to make it work. I'm so tired of waiting for Apple to fix this WiFi bug. I don't think it will happen soon, therefore I'm willing to try everything I can instead of just waiting. I'm so close to restore my late 2012 i-Mac, which worked perfectly before the "upgrade", back to factory settings. For the past couple of weeks I have been attempting to correct this so irritating bug without a permanent results. Thank you.

I received an update a couple of days ago to 'Pages'.     Wifi seems OK now although I am reluctant to say this.   I did do a system reset as well.

Well I spoke too soon and the crossed fingers sure didn't work !   Back to the drawing  board

OK, founded on the second page on this discussion forum. Applied his first step which removed my old and created a new WiFi 2 system for my i-Mac. Now my computer has a new IP. Earlier today and I'm not sure if it's relevant I went to my Air Port Utility and under "Internet Options" changed configuration of IPv6 from "link - local only" to "Automatic" to match my computer network setting in Network Preferences. Before performing above step one suggested by 'nicknish" and also performed by 'huxtableb" IPv6 values were not populated, however after the step one most of these spaces were filled. So, I think if you just apply the first part of suggested fix every thing related to IPv6 will be filled automatically. Just please make sure that configuration of IPv6 in Air Port Utility and Network Preferences are set to "Automatic". After the fix I downloaded couple of movies and streamed them to Apple TV and the WiFi signal did not dropped once. It was not possible before. Well, it all make sense because by upgrading from Maverick to Yosemite some of my WiFi settings were not set correctly. Actually they were left as Maverick WiFi settings under the new Yosemite operating system. I'm using three years old Motorola Surf Board modem and Air Port Extreme router. I'm sure that many of us should have their WiFi issue resolved after performing suggested fix. Wish you all the best luck.

PS;

I did have to reboot my computer twice; as suggested and at the end because my WiFi icon was gray out with an "x" in it.

Regards,

Unfortunately I was over enthusiastic and reported above fix as a success too soon. Like everything else suggested on this forum I have tried eventually failed. I'm not sure if without Apple help anything is going to work. It's making me sick and also depressing because who knows how long is going to take for Apple to fix it. I can not imagine using my computer in the current state for much longer. I'm recovering from a total hip replacement surgery so do not have to go to work. Most of my free time in the past two weeks I dedicated to researching and fixing this WiFi bug. Thanks Apple.

Hi Warszawa,

it take, physically, 21 minutes to clean-install Mavericks. Another hour, using Migration assistant to move data over.

I suggest, you use your time more efficiently than attempting to debug WIFI issues on Yosemite. As you state yourself, that is the job of Apple.

I am not trying to be cynical here but constructive. In two hours, from reading this, you can be happy and on your way to spending your time more effectively.

IHTH

When I first installed Yosemite on my MacBook Pro and iMac, I noticed the Wi-Fi issues. Someone suggested that a "clean install" might fix the problem. So, I did just that with my MacBook Pro (Yosemite clean install), but left the iMac unchanged. In side by side tests, the MacBook Pro was fine (no Wi-Fi issues) while my iMac continued to drop off intermittently. While it may have been coincidence, the clean install did resolve the problem on my MacBook Pro and I did the same thing with my iMac -- no problems noted since. Just wanted to pass along my Wi-Fi issues as well.

I finally got my wifi straightened out and thought I'd post here to see if it helped anyone else...

My problems started with the first Yosemite Developer Preview.  Wifi would just drop randomly and the menu bar wifi icon would go gray.  I couldn't just reconnect to my wifi, I had to turn wifi off then back on and it would stay up for a seemingly random amount of time.  Sometimes it would seem to be every 10 minutes, sometimes it could go hours without dropping.  I filed lots of bug reports with Apple, but they were always closed as duplicates.  But whatever, I knew the risks of running betas.  The the GM release came and had the same behavior.  Then the 10.10.1 beta still had the same problem.  I started to research solutions.  I tried the least invasive (deleting some files from SystemConfiguration), but no luck.  No luck deleting my existing remembered wifi connections either.  etc. etc.  I was about to give in to nuking my hard drive and re-installing. 

But I started thinking about what else was attached to my network, when I remembered that I had an external drive attached to my Airport Extreme (the wireless N, flat one)  and I was using it for Time Machine for my MacBook Pro and Mac Mini (but the Mac Mini is hardwired, not wifi).  This has always been an officially unsupported use (the newer tower Airport Extremes apparently do support this), but it worked fine in Lion, Mountain Lion, and Mavericks.  So I removed it from the Airport Extreme, used the Airport Utility on the Mac to make sure that it didn't think it was still attached.  Then on the MacBook Pro, I went into TM Preferences and made it forget the TM Drive.  And I've had close to 72 hours of wifi connection without it dropping and going gray.  Downside is that I lost my TM backups for both the MacBook Pro and the Mac Mini.  I even attached the external drive directly to the Mac Mini and told TM to use that drive, but it wouldn't pick up on the existing backup and insisted on starting a new one.  So I just left the external drive attached to the Mini to do its TM backups and pressed another external drive into service to do TM backups for the MacBook Pro.  So now, I have to remember to periodically connect the drive to backup my laptop, but my wifi issues are solved.

Are you suggesting that clean Yosemite install will take care of my WiFi issue? Would you be so kind and guide me through this process in steps? By wiping previous WiFi setup and letting Yosemite OSX to generate it's own WiFi setting I was under impression that it should do the trick. Unfortunately it didn't. If you could point these steps out I would greatly appreciate your help. Thanks.

I can personally vouch for the fact that clean-installed Yosemites also exhibit the WIFI (Network) issues.

Could you guide me please in steps how did you clean install Yosemite on your i-Mac? I have a late 2012 i-Mac with a Yosemite installed over Maverick and suffering from random, intermittent WiFi drop off. Do you know a simple way of doing it without restoring my computer to factory settings? Thank you.

So what are you suggesting? I was under impression from your earlier reply to my post that a clean Yosemite install will eliminate the WiFi issue.

Thank you Greg and Good For you ... Good for keeping it simple... I upgraded to Yosemite on the Day it was released and have had NO problems whatsoever... Lucky I guess and Also the only problems in my house is the El CHEAPO Time Warner Belkin Wi Fi Router they gave us... which I sometimes have to unplug for a minute and then plug it back in... after that... always clear sailing for days... My Gripes are with that GD iTunes 12 and its interface which I sent Jony Ive and Email about... what a bunch of BS that App is now!
