Q: OSX Yosemite Wifi issues
-
Dec 5, 2014 6:37 PMby nhcowboy,And here's the real kicker! I saved up to buy the new 4K resolution super dee dooper Mac. Apple lost out on a couple grand sale and my hard worked for christmas present to me just bit the dust. How good can any computer be that can't just go on line? I'd never buy it now. No screen resolution is good looking at loading and loading and loading websites. Apple, slow down and make things that work and deliver the goods sans headaches.

I followed step 1. It worked perfectly for me. Now no more wifi issues.

Dec 6, 2014 11:11 AMby gadgetcoma,Solutions Tried
- Deleted WiFi adapter and readded
- Removed all preferred WiFi networks
- Deleted system config plist files from the Library folder
- Disabled bluetooth
- Disabled handoff/continuity
- Disabled awdl0
- Contacted Apple Support. They had me boot to recovery mode and test internet connectivity. Everything worked, but since the problem is intermittent, I don't think that's a good test. However, based on this, Apple asked me to do a clean install of Yosemite.
Solutions to Try Next
- Do a clean install of Mavericks and test. (Currently underway. Installation complete. I've been using the system for nearly 4 hours so far with rock solid WiFi.)
- After sufficient testing with Mavericks (a couple of days, at least), do a clean install of Yosemite.
- If problems return with Yosemite (I'm guessing they will, but I'm keeping an open mind), I'm heading to the Apple Store with multiple wireless diagnostic reports, the history recounted above, a copy of Mario Ciabarra's article, and (if someone can tell me how to easily print every page) a copy of this thread - or at least, a reference to it.
I wanted to circle back with an update.
Additional Solutions Tried
- Launching Network Assistant and keeping it running - no effect
- Changing permissions on the wifi password in KeyChain Access - no effect
- Run Mavericks - no problems... and I ran it for two days
- Clean install of Yosemite - problems showed up within 15 minutes.
- I captured wireless diagnostic reports of the problem for both my original Yosemite install and the clean Yosemite install.
Apple Support Experience
- Made a third call to Apple and explained what had been tried. (They actually had most of the history and didn't need me to repeat it.)
- The advisor immediately transferred me to a senior advisor who confirmed a few details and then brought a wireless senior engineering associate (or something like that.) Based on her knowledge, I'm guessing she was a senior support person with direct access to wireless engineers/developers.
- She sent me a diagnostic tool to run when the problem occurs so they can get more detail. I captured this information and sent it to Apple along with the two wireless diagnostic reports. That was this morning (12/6), so they won't get to work on this until Monday, most likely. I was told to expect a follow up call later next week.
- I give Apple support credit for not pushing this off as a hardware issue and for accepting my troubleshooting skills. (I've done a lot of system support over the last 22 years.)
Let's hope this gives them more to go on for finding a fix. I'll report more as I hear back.

Dec 6, 2014 2:25 PMby Florian Innocente,10.10.2 b1 changed nothing. Beta 2 that shipped tuesday resolved all my problems so far.
I use 2 mid-2011 iMac. One at home, one at work, so two different contexts.
It's been a nightmare with Yosemite, they were constantly dropping connexions. I had to manually deactivated and reactivate the Wi-Fi, again and again. So I used the iMac at work with Ethernet only.
Nothing changed when I applied 10.10.2 beta 1. But all friday working with b2 : not a single drop. At home, I used it this saturday, something like 4 hours, and I had just 1 drop (it used to be several times in the matter or one hour). So it is a real and strong improvement, at least in my case.
And I haven't done anything else than upgrading to this second beta. No other trick ou setting.

Having the Network Assistant started seems to be working for me as reported by Blondel.
Tried awdl0 thing and Bluetooth disable before. Those did nothing.
Also removing old networks. Did nothing.
So far so good my merely starting the Network Assistant.Marvelous! I've told you Blondel may very well have stumbled on something important. Now how do we get such a goofy workaround known to Apple for further analysis?
And what are the implications of having Network Assistant running? What services does it exclude? Is your Mac really running Unicast DNS now? Does it leave AWLD alone? Does it leave IPv.6 alone? Does it send single packets instead of duplicates as well? Would be nice to know.

Dec 6, 2014 4:00 PMby hexdiy,Sorry the Blondel trick hasn't worked for you, adding to the mystery. Seems this whole issue is hardware configuration specific. Which makes it difficult to reproduce.
Do you have any internet capable iDevice in the vicinity of your affected Mac? If so, try and remove it.
If problems return with Yosemite (I'm guessing they will, but I'm keeping an open mind), I'm heading to the Apple Store with multiple wireless diagnostic reports, the history recounted above, a copy of Mario Ciabarra's article, and (if someone can tell me how to easily print every page) a copy of this thread - or at least, a reference to it.
You don't mean printing every last page of this thread do you? Are you kidding?
Anyhow, good luck!

Dec 6, 2014 7:19 PMby eas2156,i'm glad to see 10.10.2 beta 2 is working for some, I haven't tested it
however, I did find the wireshark article: http://markmaunder.com/2014/11/13/os-x-10-10-yosemite-wifi-problems-analyzed/
re: "...someone used wireshark and found that yosemite was sending duplicate packets, which might explain why wifi is slow."
I only notice wifi slow using safari, not google chrome

Dec 7, 2014 5:25 AMby gadgetcoma,1 silly question: HOW do i get my wireless and other diagnostic test reports to Support?
You need to convince Apple Support that they need the diagnostics. For me, that required multiple calls through which I tried their troubleshooting suggestions (remove system config plist files, delete adapter, delete preferred networks, clean install, etc.). Once I showed them I went through all of these steps, they sent me the capture program which gave me the ability to upload diagnostics to them. If you've gone through all of the troubleshooting steps I mentioned, you may be able to convince them to send you the capture program with only one call to Support.

Dec 7, 2014 6:24 AMby TomsApple,The Yosemite 10.10.1 seemed to fix my WiFi signal issue but it suddenly re-appeared this past week ... 12/4/2014 ... another thing is that the slow boot was never fixed and seems to be getting worse. Just thought I would add another voice to this and related issues.
