OSX Yosemite Wifi issues

The mad thing about all this, is that Yosemite is so darn silky and smooth when network is following suit. When NOT the system degrades a lot...

It is not just that WIFI (Networking) stops working. If it would be just that, fine. But WHEN it stops working or gets in trouble, the whole system seems to slow 2 a crawl. If one enters the console @ that point, he finds 100s of Console Messages per second which amounts to thousands in a few minutes...THAT slows the system down.

I have tried just offing WIFI and all Networking. That creates havoc on the computer as most OS X Apps are network-junkies - not knowing what to do once a network connection isn't present...

It would be nice if those apps would be able to work without a network connection.

Morten James, besides my former posts (just testing/conjecturing), I think Handoff and Bonjour sleep proxy may be the issue here. Only they are new on Yosemite (- fault finding by logical exclusion). Bonjour spoofs your computers' Mac address when it sleeps. With Handoff coming online on Yo1010, multiple iDevices will request an almost continuous wake up call to your Mac. Just turn off wake-on-lan and see what happens.

My old router worked perfectly with everything (all Apple devices) not running Yosemite as well, however Yosemite created a specific environment which doesn't seamlessly merge with some of the networks. I did experience a similar issue on the i-Pod Touch 3 with one of the two digit software upgrade. It was a wide spread WiFi signal fluctuation issue for a wide range of users with older routers. Well, I'm now in day four and doing things not possible before new router purchase. Network extension with the factory restored old router runs good as well. Hopefully it will stay that way. Take care man.

I take it people are aware that the second beta of an OS X Yosemite update (10.10.1) was released to developers a week ago and that one of the core focus area's is Wifi?

Hi OP -

I believe anyone with a Network issue is aware of this. However, 10.10.01 is a beta in development. Which means that it could take between today and a month or longer before it arrives. Could also be that it arrives earlier and does not fix the bug. No one knows. But due to the cunningness of this issue and the inability of providing a solid repro-case as in "Reliably reproduce/trigger the bug" this could take a while. And if someone relies on an active internet connection, the only choice as of now is to use the fixes which will fix the issues, albeit short-termed-ly.

I have been trying since the developer preview to reliably trigger the events leading to that specific issue and thus far, have not been able to.

I have tried everything to fix this problem and today thought I was there. I had 6 hours of connection then off we go again dropping every 5 minutes. Nothing had changed on the network or the computer. This needs fixing urgently it is a major disaster. Strangely the problem is only on specific wireless systems and nothing suggests anything different has to be something inside Yosemite.

---- UPDATE ---- 10.10.01 is here... Check to see if this fixes the issues FIRST

So - I have found ONE way that takes care of my Network (Internet Connection) Issues, Immediately.

Symptom....

Network/Internet Connection crawls to a slow and terminal fills up with odd messages and thousands of them.

Or I loose Internet connection (NOT WLAN) completely.

I cannot say whether below will indeed work for you guys as I might have done other things to my system to troubleshoot; be that deleting certain preferences etc. But perhaps it can help. If you want to do it, follow along:

Open Script Editor from Utilities Folder and paste the following lines of code in to it... Replace YP (after the password) inside of the double quotes with your computer password. Don't delete the double quotes...

tell application "Finder"

do shell script "sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.sandboxd.plist" password "YP" with administrator privileges

do shell script "sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.metadata.mds.plist" password "YP" with administrator privileges

do shell script "sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.audio.coreaudiod.plist" password "YP" with administrator privileges

do shell script "sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.discoveryd.plist" password "YP" with administrator privileges

do shell script "sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.discoveryd_helper.plist" password "YP" with administrator privileges

do shell script "sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.coresymbolicationd.plist" password "YP" with administrator privileges

end tell

Then from the File Menu select Export (Under File Format select Application and tick Run Only) - Name the App "0 Total Unload" without the quotes

Then create a new Apple Script and paste in the following:

tell application "Finder"

do shell script "sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.sandboxd.plist" password "YP" with administrator privileges

do shell script "sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.metadata.mds.plist" password "YP" with administrator privileges

do shell script "sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.audio.coreaudiod.plist" password "YP" with administrator privileges

do shell script "sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.discoveryd.plist" password "YP" with administrator privileges

do shell script "sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.discoveryd_helper.plist" password "YP" with administrator privileges

do shell script "sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.coresymbolicationd.plist" password "YP" with administrator privileges

end tell

Then from the File Menu select Export (Under File Format select Application and tick Run Only) - Name the App "1 Total Load" without the quotes

When you are done - go to the desktop an run Total Unload. Wait for a 10 Seconds and then Run Total Load.

That will toggle those daemons off and on...

In my case, this restores my Internet Connection Immediately.

If you don't want to create an Apple Script, you may run the commands one after the next inside of the Terminal. But that is tedious and much faster with the script... But in case you want to do it here is how... Copy the the following part, highlighted in Red from the example below, from the strings above....

do shell script "sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.sandboxd.plist" password "YP" with administrator privileges

JJust Downloaded and installed with working network. After update nothing works. Can't connect to web at all. no tricks are working. For me, 10.10.01 is worse than 10.10.

WRiting from iphone as Mac can't connect at all. I will have to go back to troubleshooting fantastic

So - I am back online - after doing the routine fixes that I have been doing the past 2 months..

This is my installation Experience

1) Downloaded the update in less than 2 minutes

2) During installation, I was given the log in screen. I entered credentials and the installer came back, stating it needed 7 more minutes. Then after 10 seconds, my desktop was there and I was running 10.10.01 official release.

3) The first thing I noticed that I was connected to my WLAN and that I had ZERO internet Connection. My console was overflowing with the same messages it always overflows with when the issue occurs.

4) I ran the usual suspects... Incl.. safe boot, SMC Reset and NVRAM reset. NO Internet.

5) I restored my Airport Extreme to Factory Defaults and created a new WLAN along with a new Network Location. Rebooted and now I am online. Again.

Latter (Point Number 5) was the only thing providing a remedy.

Lets see how long this will last...

Anyway, 10.10.01 does NOT fix the WIFI issues. I had to go thru the same extreme routines I have had to go thru' the past 2 months to be able to connect to the internet.

This is not a very good sign. Because this indicates that no one has been able to reproduce a clear-cut scenario in which this happens. So we are back to square one...

To anyone with issues after 10.10.01

Try Resetting the Airport Extreme or other router - to factory defaults. See your documentation on how to accomplish that. NOT just a reset.

Then Create a brand-new WLAN Network

Then from network settings create a new Location and apply that.

That did it for me !

That's all well and good, but not everybody has an Airport Extreme.

Infact most of the people I know use the ISP provided WiFi router.

Or have business grade Meraki or Cisco - these are working fine with every other version, except Yosemite 10.10.1 - even windows works flawlessly 🙂

Then those folks should try to reset those to Factory Defaults....

Not saying it should not work out the box... But clearly this problem is bigger than anyone thought !

Sadly in a real-world it's not viable to reset all the devices, especially the business grade APs, for example Meraki APs which are cloud configured, the Cisco Aironet APs are controller based.

Also, if the configuration works for everything else without problems, then it's 100% Yosemite that's the root cause of the issue.

I've been looking through the logs on the Cisco APs, and there is nothing to indicate any problems at all, apart from indications of the Yosemite device "going away"

I've got Windows machine with Windows 8.1 and wireless A/C, that works fine, I've also got a Mavericks MacBook Pro, and that works fine, as does the Mavericks iMac - the only machine that's having problems is the identical hardware MacBook Pro, which has Yosemite. - all of these are connected to a Cisco 3702i in Autonomous mode (No need for a controller).

I strongly suggest that anyone having issues send feedback to Apple about it.

It is quite obvious with this new update that they did not have any clear-cut repro case which would reliably trigger those devious events.

Before installing Yosemite, I cloned my Mavericks install to an external USB drive

if I boot on that, the Wifi issues disappear, proving it's not the hardware but Yosemite

Additionally, If I turn off wifi, then turn it back on, my Wifi speed restores to maximum and stays there until I do something silly like click on airdrop

(I had my SSID details displayed by alt-clicking the Wifi option, then went to Airdrop in Finder .. the speed immediately dropped)

One more note, run up something like Wifi Explorer .. and watch 2.4Ghz SSID's randomly disappear for a while and return. This never happened under Mavericks

and is verifiable on another device (e.g. PC) as a Yosemite only issue
