Q: OSX Yosemite Wifi issues

How do you know that they take a time and read your reports?

Because they communicate with me. That is what happens when you submit reproducible bugs instead screaming like a spoiled child ;-)

Please, you can be possibly serious about expecting from all of us after spending a ton of hard earned money on Apple staff to get involved in software troubleshoot process.

From where I'm sitting, it certainly appears that you are very much actively involved in troubleshooting. If you had put half the effort you took writing up on this thread in to reporting bugs to Apple, you might have helped fix the bug. Perhaps one of the system diagnoses you would have sent in, could have contained the golden clue..

I could be wrong but the way I understand a purpose of this forum is to share our experiences, opinions and if we can help each other with an information which could contribute to resolution of some of simple, common issues.

You are not wrong... And this forum is great for such.... But when it takes a turn where good information becomes flaming of developers, it serves no one any good. If going here to get advice and all you read is "Apple is this Apple is that" / then what the heck am I going here for...

I have the opposite issue. 5GHz works great (in some modes) but 2.4GHz is super slow.

+1 for that. Anyone should use 5GHZ where he can

Just upgraded to 10.10.1 and my Wi-Fi appears to be fixed.

I have been having numerous issues with Yosemite on my 2013 15" Macbook Pro such as whole system crashes and WiFi/Bluetooth issues.

Last night I updated to OS X 10.10.1 and although it seems stable so far and light browsing seemed ok, a speedtest revealed the speeds to be about a quarter (both up and down) of the normal speeds.

I really hope Apple has fixed this, I only recently bought the Apple Wireless Keyboard to avoid wearing down the Macbook's keys but with the Bluetooth issues of late, I'm noticing my Macbook is beginning to look worn with all the typing I do

Try to remove any DNS.

I had the DNS from google (8.8.8.8 and 8.8.4.4) and had problems.

I removed the DNS and everything has been working well

Yep - since upgrading to Yosemite, my Wifi keeps cutting out. Sometimes it works for an hour before doing so, other times it could be a minute. Oh, and sometimes it tries to fool me - by showing a strong signal - but it's lying.

Installed the patch 10.10.1 today - it did not fix the problem. Apple seems to have screwed up big time.

I wouldn't usually bother to post up as you're all doing a fine job, but I understand that Apple does look at how many postings there are on a topic, to see whether to try to fix it. So, everyone visiting here, if you have a problem with the WiFi/ Yosemite thing, LET APPLE KNOW by posting here. Maybe they'll do something.

Indeed Ecocetit. I'm using a Sitecom WiFistick with a Ralink RT3572 chipset on my old MacBooc Core Duo under Snow 10.6.8 because the reception/transmission is better than the internal Airport.

It uses its own drivers, and a program called "Ralink Wireless Utility". Bit buggy after computer sleep but sure does work and perfectly mixes with Airport. Just another Ethernet device/ card on your network (En2).

Don't know if it will still run on an OSX higher than Snow. But an interesting test case it might prove if indeed it would still run under Yosemite!

Just before posting this, I've switched off Airport, and logged into Apple Support again, in order to post this over the Ralink stick. Just testing.

+1 for that. Anyone should use 5GHZ where he can

Indeed. Everybody is crying wolf here over Yosemite software. Understandable, in some way.

But this thread shouldn't be used as a garbage can for any old WiFi issue. We all should know running Bluetooth will create interference on the overcrowded 2.4 GHz band.

We all should equally be aware (and this fact is rather less known) that running a simple USB3 external device will also create ample interference on the same 2.4 GHZ band. http://www.intel.com/content/www/us/en/io/universal-serial-bus/usb3-frequency-in terference-paper.html

We all should as well be aware that the issues described in this thread may only be happening along with/ due to the use of specific older routers. Which makes reproduceability of the problems wellnigh impossible.

On top of that there is also an issue that has not been touched upon in the whole of this thread: Internet Service Providers and their tricky practice of Traffic Shaping: some providers, whenever they sense your computer is reaching a big link speed, will throttle your Internet connection, especially during business hours. Now maybe, just maybe, for some reason, Yosemite is a bit more speed hungry than Mavericks and you are with an ISP using Traffic Shaping. In that case you will be ok for a minute or 2, until throttling sets in.

Whats more, there is the issue of ipV6 barely coming into action globally, whereas Apple has had it built into Mac OSX for aeons. What clashes may this fact cause?

And the last one: DNSsec coming to bear globally, and not being implemented in most places/ servers yet.

I'm just a fairly average user with an interest in all of the above, but seeing all this i'm amazed at all I can still get to you over the internet.

Dear Apple devs, you have my respect, please deserve our sympathy as well.

Just received a very fascinating update from a correspondent of mine who is actually testing Yosemite against Mavericks (I do not have the hardware for it myself, nor the exact IT knowledge, just reporting):

it seems whereas Mavericks places a call for DNS to the wan/router, and next a Bonjour call (.local), with Yosemite it is the inverse: Bonjour call first, DNS request second. And it seems the Bonjour call gets stuck sometimes. This might also explain the proliferation of instances of "Phantom Macs #x" in the sidebar (my own remark).

Thus, the already mentioned workaround of temporarily switching off "wake-on-lan" gets shed in a new light. Just try. (My own conclusion).

Any comment here?

They do communicate with you? That is great, then I'm confident that you guys are going to fix it soon. Correct? At the same time I would like to clear some big misunderstanding or misconception about a simple consumer/manufacturer/merchant contract which is a product purchase. Under that contract manufacturer/merchant is obligated to deliver a market ready product in exchange for a full payment. Simple, isn't? Not for everyone, not anymore. We the consumers by lowering our standards and expectations are encouraging companies to lower their effort in maintaining products quality. Apple stuff almost never go on sale and we are usually paying MSRP for it. I'm asking once again; why we can't expect fully functioning products in exchange for an inflated payment? All this talk about human imperfection in this case is unnecessary.

Addendum to the above: incomplete Bonjour communication clogging up the network would corroborate the suspicion that older routers clog up the network under Yosemite, not under Mavericks, where DNS is handled first thing.

I had the same problem with my NetComm Wireless router but fixed it by changing the router security configuration as below:

Network Authentication to WPA2 -PSK

WPA/WPA2 Encryption to TKIP+AES

Rock solid wireless connections with no issues at all.

I would like to point out that This Thread (WiFi Issues) is a Tiny Minority of People who own Macs of every type... and that The Vast Majority of people are having NO Problems whatsoever like myself... YES I noticed some Yosemite Bugs but nothing that stopped me from getting serious work done like the 8-10 hours a day I'm at Work designing Print Ads using Adobe Creative Suite and Short Videos Using Final Cut Pro all on a Lowly Plain Vanilla Non-Retina Mid 2012 Macbook Pro.

Yosemite 10.10.1 Fixed all tiny anomalies I noted earlier but none were related to Wifi.... I couldn't even begin to know how to do all these Advanced Tweaks and Settings changes listed here so I'm glad I stay out of those dialogs... which is where I think people screwed up their systems prior.

I believe some of these people on this thread need to go back to a Windows machine because they like technical troubles and don't know how to use a computer for work so they dig into the System deep and mess things up and then blame Apple because they can't "get down from that tree."

I have Many Windows Friends who spend all their time while I'm at a Real Job Tweaking their systems and when I get home they're soaked in sweat resorting to reinstalling their whole hard drive after running them in the ground. One Guy Defrags his Hard Drive Every Day..

The reason Apple isn't responding publicly because they know what I know and that is ya'll be creating most of these problems Yoselves...truth be told...

I'm a Graphic Designer ... not a techie but they aren't happy unless they got an error message on their screen... gives them something to do tomorrow while I'm at work ...  I keep getting emails regarding the problems here but honestly If I was Apple I'd buy you all a Dell Laptop and say Good Riddance!

Never had a wifi problem in any of my mac computers until the second I upgraded to Yosemite. And I don't tweak my computer. Your not having a wifi issue is just luck. And your inability to understand how your computer works is not a virtue. And your off-topic post is disrespectful. There should be some way to flag comments from children that are off topic and disrespectful so they can be removed.  

When Yosemite was released I upgraded and when IOS 8 was released I upgraded. After upgrading all my devices I began having WiFi issues non-stop. I tried all the posted fixes. Nothing was the absolute fix for my WiFi dropouts. Then I tried changing my DNS server setting to use the public Google DNS server:  8.8.8.8 and 8.8.4.4, I have 3 Macbook Pro's, 2 iPhone 6, 1 iPhone 5 and a iTV. When I changed my DNS to the Google Public DNS server all my problems went away on all my devices. I have been drop-out free for over a month now on all my apple devices. I have internet service is Comcast Extreme 105 MPS. The Comcast DNS server was the problem for me.  I would recommend changing the DNS server setting for all your devices to 8.8.8.8 and 8.8.4.4. and see if your problems go away.   Also I called Comcast, they insisted their DNS server was not having problems and of course this call was supported from India so I gave up trying to talk to the support person.

I have to conclude it was not the Apple devices having the issue but my internet service provided.
