Q: OSX Yosemite Wifi issues

http://www.macworld.co.uk/how-to/mac-software/revert-back-mavericks-from-yosemit e-3581872/

UPDATE #2:

So I had the MacBookAir picked up by Apple for a potential hardware repair, and although they couldn't reproduce the issue at first, when they put it to sleep overnight and woke it the next morning, they could reproduce it.

Upon waking the wifi, although 'on' in the menubar, was 'off' in the system preferences. Turning it back on here, the button does nothing.

They have diagnosed a wireless card problem and it's on order to replace.

Although I, nor the Genius could locate a wireless card fault, they are replacing it anyway.

I'll report back when the new card is in.

I had the same issues as you describe (on a MBP 2011)

I worked with Apple tech support and the seed program

I replaced modems and routers

3 weeks ago I went to a Genius bar and they could not detect a problem

We decided to replace the WiFi card and ribbon

WiFi has worked as normal ever since

(I think it was a software / hardware issue rather than a failing card since the WiFi was only problematic in some specific locations and that no longer occurs)

If anyone is really frustrated and has tried everything else (like I had), I would recommend a new WiFi card. Mine was supplied under warranty.

Not only I experience the Wifi issues, and I tried ALL PUBLISHED SOLUTIONS. Also, this most stupid of OS I have ever encountered, manages to drop ethernet connections as well. So, I have my MBP's attached to an ethernet connection and they drop? ***.

And now for the fun part, I have a Windows7 VM machine running. When I set the network connection to bridge, i.e. let Windows manage Wifi, guess what: NO ISSUES. At the same time back to the OS X host, no Wifi connection. Apple! LOL.

Here's another clue, although I'm not sure how much it contributes.  I was able to stream a TV show from my MBP to my Apple TV with only a few slowdowns during the first few minutes of the program. It worked flawlessly for the next 90 minutes.

Is there something in the WiFi settings locked by watching a streaming video?

yesterday beta realise is ok for me. Wifi very speed and any stop.

Thanks! This was the only solution that worked for me!

Wrong. We’re not here because we gave up responding to irrational comments long ago in this thread. I installed every Yosemite update the day they were released and I have had none of the WiFi issues reported here. Do some have these issues? Absolutely but nowhere near the percentage claimed by the commenters. Misery loves company and it feels better to be part of an imaginary multitude of victims. It is long known that Apple is concentrating on certain bugs with each Yosemite update and WiFi is on the list. However, no matter how many updates are released there will ALWAYS be a core group still complaining about the issue. It will never go away for all. And all bugs are like that.

What worries me in this thread is all the voodoo and configuration fiddling being advocated. What happens when the actual ‘fix’ comes out? Will these users even remember what they did beforehand? Probably not and we’ll be hearing from those users with new lamentations about how things are broken. Vicious circle.

I am having the same weird WiFi issues.

iMac (21.5-inch, Mid 2011)

Yosemite 10.10.10

It works for a while 5minutes to an hour and then just freezes. When it Freezes the whole machine gets super slow until I turn WiFi off/on.

I have Wiped the Hard Drive and done a completely new installation. I have removed all of my networks and re-authenticated. I added a new location.

It happens with my FiOS router more; but the same happens with my Airport/TimeCapsule. 2.4GHz or 5.0GHz is the same.

It is less frequent with my MBP which is a newer model.

I see correlation to it stopping when I am doing large network uploads. (Moving large amounts of files to my TimeCapsule or FTP to a webserver)

I have tried changing DNS and MTUs.

I got nothing on what this is or how to resolve.

Has anyone had real success in fixing this?

Instead of sitting and doing nothing you need to start looking elsewhere for your issue. WiFi is an extremely complicated technology. Interference can come from numerous sources, especially if you are in an urban area with lots of WiFi networks nearby. Just because your Mac is near your router doesn’t mean you won’t have issues. Channels use, 2.4Ghz or 5Ghz nabdwidths, electrical noise, physical impairments (like metal doors, cabinets, walls, etc) can all be the issue, not necessarily Apple’s software.

For the record, I am running Yosemite 10.10.1 with an Apple Airport Extreme Base Station with absolutely no issues. I have 9 wireless clients using the network, including two iPhone 6s, an AppleTV, an iPad 2, A Samsung HDTV, A Samsung Blu-ray player, and a hardwired Yamaha AVR. Rock solid. Everything just works.

LOL

> Do some have these issues? Absolutely but nowhere near the percentage claimed by the commenter's.

You got any citations for that bold claim? I've got 134 pages of evidence that this is affecting a *lot* of people, and these are just the people that can be bothered to complain about it. Sure, lots of people use Apple, but to dismiss all these people's claims like that is just stupid. Get off your horse, and get off my lawn.

> However, no matter how many updates are released there will ALWAYS be a core group still complaining about the issue. It will never go away for all. And all bugs are like that.

No, they're not. This isn't just some minor bug, this is a fsking production stop. Do you even understand the difference? I'm amazed at your irreverence to such a serious problem. You've been brainwashed by Apple.

Guess what *******? There's a really easy way to see this is an Apple a bug, and not "some complicated interaction",

Step 1: Boot up Linux laptop, connect to network wirelessly with no problems, no drop-outs, every thing is fine. All those "complicated things" are clearly not the problem.

Step 2: Boot up Mac Mini, late 2012 model. Connects to network, but service degrades after about 1/2 hour to something unusable.

Let me explain the obvious conclusion to you: by construction, I have shown this a bug with the Mac Mini software / hardware. I'm guessing software because it only manifested itself after the Yoshitonme upgrade.

I agree that the wifi issue is a Apple/Yoshitonme only issue. I recently spend six weeks in Altanta and had the exact same issues as I did at home in Florida. Different routers, same results.

@chturne, I was addressing the really arrogant post by lkrup, reminding him to the fact that he suggested himself that we as users should go on a wild goose hunt to get this apparent software bug fixed. Then he claims its all voodoo. So, this whole nonsense of 'some complicated interaction' was by the so called expert lkrup. Read my post more careful.
