Q: OSX Yosemite Wifi issues

I think this seems to have worked... so far so good... fingers crossed now.

I agree and noticed the same as I run Windows 7 Pro in Boot Camp under Yosemite. All the drivers work very well in Windows. That is why I am of the firm belief that the Hardware Drivers and Intel Chipset Drivers are not totally compatible with OS X. Apple is going to be mulling through lots of code to get these drivers to work well in Unix. Not to mention, has anyone noticed that OS X does not have a basic Network Set up during Install or Upgrade?  Windows has that feature during install. If you Cancel out of it, Windows will set up basic network settings based on what it retrieves from your hardware and user input. Apple will reach a milestone when all is said and done. One OS X across multiple platforms. This is a big deal! Microsoft is promising this with Windows 10, by that time, they will be asking Apple, "How you Guys did that?" I am running Mavericks and Boot Camp well on my Mac Mini late 2012. Looking forward to the New Yosemite. Still cheering for Apple!

LOL it's an automated email, sent to apple IDs that had logged into this thread.

Personally, I didn't want to work for free doing beta testing Apple should have already done, and it was a bit offensive. I was already the victim of Yosemite, it wrecked my system, and the very notion that I would volunteer for more problems just shows you how presumptuous and narcissistic Apple has become.

I've certainly learnt my lesson. Never being an early adopter again.

I felt pretty annoyed when Captain Cook said beta testing program was a success.

(If it works....don't change it.....don't even touch a thing.)

The 3rd beta of 10.10.2 (build 14C81f) still does not solve the wi-fi for me : I have a 27" iMac Late 2013.

I cannot count the number of hours lost and frustration from these issues. (it feels like the old pc days when you spent more time trying to make it work and stable than to actually work !).

When you buy a 2500$ box in 2014 you'd not expect to have such a miserable experiment with wifi connectivity.

It is hard to bear for the "most advanced OS in the world" !

And I'm also quite surprised since my iMac is recent, it seems people with much older iMacs have less issues...

Enough rant, and I'm not a usual complainer, but here it is really annoying...

For me, after resetting SMC and PRAM and removing/readding devices, it seems that I can't have bluetooth and USB 3.0 at the same time due to interference (apparently Intel released a white paper on the issue: http://www.intel.com.au/content/www/au/en/io/universal-serial-bus/usb3-frequency -interference-paper.html). When I do, WiFi speed is miserable.

So it becomes a toss up between having USB 3.0 devices, WiFi and Bluetooth...choose two.

I think I need to change my WiFi to maybe ethernet over power (EOP) or somehow figure out how to get WiFi through 5GHz only. I'm not sure how to limit all WiFi traffic to 5GHz.

I got a call from an Apple Tech, following my comments here, and after a two-hour convo, he said I would get an invite.

Hi,

I am having similar issues with Yosemite and Mac mini 2014 - experiencing random slow downs on 2.4GHz or 5GHz. I have dual band Asus router N66U - its a stable router, so it is not the issue here.

The connection starts to slow down few minutes after the boot up.

For me the solution is: disabling wifi (the menu bar) and re-enabling wifi makes the WAN connection stable.

Other solutions (removing network preferences, etc.) did not worked for me. I have no clue whats is going.

Wireless settings on my router (5GHz and 2.4) have been WPA2/WPA Mixed Personal since I installed it;  A few months prior to upgrading to Yosemite.  When it is connected it works like a champ.  I don't experience the slow speeds others are.  Mine just drops off.

Are you able to login to either ghz?

It's worthless discuss about my wifi 5GHz problem ..... Everybody have the same issue!

APPLE!!! What's going on? Everybody have the same errors! Fix Fix Fix.

Same here, have tried pretty much every fix here.  Either hoping this gets fixed soon or I'm reverting to Mavericks this weekend (i don't think we will see a fix in the next couple of days - bonus if we do).

Yep,

Both have the same experience.  Just drop off at random intervals.  It can be minutes, hours, days; the only consistent action is that it WILL drop.  Sometimes it magically comes back by itself (very rare).  Most times I just disable/enable wifi manually.  Again, to beat a dead horse some more, on Mavericks WiFi never dropped.

I'm not sure about the WiFi drop-offs but the slowdowns and interference are looking less and less like a bug and more like the fallout of bad technical design. What is the main difference between Yosemite and Mavericks?

Continuity/Handoff/Airdrop

Think about it, it's the only (major) new feature that touches networking and the only one that conflates WiFi and Bluetooth in completely new ways. I'm sure Apple engineering is trying very hard to juggle all the DNS/Bonjour advertisements, power-saving features of the chipsets, across Mac OS and iOS, etc. but it must be very difficult to find the right balance that works well on all the supported hardware.

The few people that have really solved it have done it by replacing the network .kext file with the version from Mavericks. That is the part of the operating system that drives the networking hardware. The implication should be obvious.

So here's a suggestion: create a new user-selectable option to DISABLE Continuity/Handoff COMPLETELY, that reverts to the pre-Yosemite implementation of the network/Bluetooth drivers. I'm sure they are trying REALLY hard to make it work, but I've lost confidence in their ability to do it. I just hope they have the integrity to admit if they screwed up and offer a way to disable "experimental" features like these for people that prefer stable/steady/high-performance network connections over fancy bells and whistles.

PS: I also communicated several times with Apple senior support and submitted data captures, but I haven't been invited to the seed program like others on here.

Hi, when we contributors here say "dropping wifi" do we always mean losing connectivity over wifi between machine and router/modem, and NOT router/modem losing connection to internet?
