Q: OSX Yosemite Wifi issues

Historically, in this lengthy thread, what you have posted has been addressed. This is not your Hardware. Proven here, are Macs and related hardware running fine until OS X 10.10, 10.10.1, and the elusive 10.10.2 "seed".

Yes we should post here to keep each other informed. We should all be using the Apple Feedback web sight and submitting our complaint about this issue directly to Apple as well.

In this "OSX Yosemite WiFi issues" thread, there are no permanent fixes or solutions. Just work a rounds by good people like you and me trying to make this bloody thing tolerable. Only to find it deepening our anxiety and make us aware of the scope of this issue. Look how far back and how many posts. That's just here. I submitted in the Apple Feedback. I ask we all do the same. One voice, one hope for an Apple solution.

I live on a farm. There are zero other wireless access points in my area

That, square_eyes, is a very rare test case nowadays (consider yourself lucky), and telltale something very big is amiss with Yosemite.

Park your ipV6 address to a "link local" address somewhere in System>Preferences> Advanced. Try to link to an ipV4 address instead.

Drop all 5 GHz attempts as well as disconnect all USB3  and Bluetooth external devices (which will interfere with the 2.4 GHz band for sure).

(sorry for the new message; got chucked out for whatever reason)

Good luck to you!

Hello again. As you know, I have upgraded my router,modem and used shielded CAT 6 cables. Whereas I'm pleased to report that Yosemite 10.10.1 is running fine on my Mini, I find myself to be an isolated "test" case because I have insulated my Home Network from little to know interference. I am surrounded by reporting SSID's in my populated neighborhood. Certain times of day my Wi-Fi Networks list is huge. Before upgrading my hardware to "suit" (for lack of a better word) my Mac Mini. This Yosemite Wi-Fi issue was very prevalent. Hence, I found this thread in my search for for a "fix". Now, in my case, the only way to reproduce the symptoms is to revert back to my original equipment. No longer have it.

Something I've been pondering and have not seen a report. Are the Mac Pro's having this issue with Yosemite as well?

As far as I know, yes indeed, John. But this thread has been a very long haul.

Has this link been posted here before? It might be helpful.

Nothing changed After update to 10.10.2 wi-fi stays not stable. I should turn off bluetooth to make wi-fi working. But I learned work without a mouse, it's amazing, Christmas magic is everywhere!  Merry Christmas, guys!!

Thanks for the link steve626. This issue is finally starting to make sense. I figured there was some interference, but couldn't put the pieces together and was leaning towards the continuity feature. I haven't had time to test everything, but did notice that airdrop definitely has an impact.

Also my workaround of preventing the MBA from sleeping when powered while less than idea has made a difference in that it's a bit more usable. Obviously not helpful for people who mostly use it as a laptop.

Does anybody know for sure if the "Bonjour Sleep Proxy" (Wake For Network Access) is strictly for WiFi connection

or does it have any effect and Mac directly connected via ethernet?

My mid2010 MBP WAS?/is affected

my grandson's girlfriend told me last night that her father bought her a new MBPS because her MBA hadn't worked since downloading yosemite and the new MBP is even worse!

Thanks Steve. But it has been posted many times. I think it is utterly informative, and very possibly helpful!

Bonjour Sleep Proxy is active on Ethernet as well. It is indispensable if e.g. you want to remotely control your Mac (Teamviewer, or any other kind of remote desktop). It is also causing the doubles of your own Mac on your network, a strange side effect which has intensified in 10.10.0, went away again in 10.10.1.

Happy new year!

A very strange thing I've found: I have a MacBook Pro (early 2012) and got the Wi-Fi incident when updated to Yosemites. I didn't shutdown the notebook but just closed the lid when I got to bed for two days. At the first day, I got the same Wi-Fi issues. At the second day (today), voilà: Wi-Fi working nice and smoothly. Is something here that anybody can explain?

Believe me: I tried all the tricks (from and outside Apple's help) and nothing worked. Any explanation? Anyone, anyone...?

Even after disabling awdl0 I've seen other issues on current hardware (MacBook Air 2014, Mac mini 2014):

• The WiFi scan is very unreliable, the variance of stations found is very high, especially when comparing to a Mac mini 2012.
• Sometimes even my 2.4 and 5 GHz networks could not be found, although they're the only ones in proximity.
• Once the connection was lost and Yosemite claimed an authentication error for unknown reasons. Manual reconnect worked without entering the password again.

It seems there's a lot of work to be done. Especially for the newer generation WiFi chips.

Happy New Year to you, I am oddly excited about posting an issue about my Yosemite install. I have repeated this for three days, three seperate occasions.

1. Startup my Mini arriving home from work. Using Firefox ( not the default browser ), surf the internet at leisure for a while and other what nots. Close Firefox.

2. Open Safari. Log in to my Router's configuration web page. Not all items of the Linksys Smart Wi-Fi set up page loads. Some items indicate  loading.... Here's where the Ghost in the Machine "Yosemite" has fun. Good name for a poltergiest, right?

3. Hit LogOut in my Configuration page. Lock up! Nothing happens.

4. Quit Safari and restart Safari."YOU ARE NOT CONNECTED TO THE INTERNET". Close Safari. Everthing seems quiet.

5. Suddenly, Router is rebooting. Of course during this process I have to wait for all to come back on line. All is fine after that. Power down. Startup the next day after work. Repeat steps 1 thru 5 all over again.

Yosemite is very inquisitive as to what and where you have put any App data or any part of it, Primarily on connected Thunderbolt and USB Hard Drives.

The Software Map that I posted you about reaches out to my Hard Drives and maps all my App data and Purchases that I have backed up on my Devices. So, it was on a daily basis. Removed all OS X Install Apps and Appstore purchased Apps from my devices. Abra Capocus! Recovered Files folder dump generated by Yosemite went away. You were correct about Discoveryd. Sneaky *******, gotcha! This doesn't happen in Mavericks.

I removed my DNS server address under the WINS tab in Networks>Ethernet and Wi-Fi. As it was not important. Renaming the .local in Sharing>Edit and changing WORKGROUP to <Name> whatever name you choose, seems to resolve the renaming itself issue in Mavericks and Yosemite. I let my Mini sleep and wake a lot to test this before posting. Back to Yosemite.

I am still, soley, of the opinion that Yosemite, just plainly put, IS NOT READY FOR PUBLIC RELEASE. It reminds me me of a couple of Linux Distributions a few years ago that talked the talk but just had way too many compatibility issues to be released to the populace. Yosemite needed 6 to 8 more months of hardcore Beta testing accross all types of environments and Macs prior to Public Announcement, let alone, release for Upgrade and Downloading.
