Q: OSX Yosemite Wifi issues

Hi there,

 

I upgraded my Macbook Pro Retina 15" (mid 2014 revision) to OS X Yosemite last night and am now having issues when using my home WiFi connection. Whilst it connects to either the 5Ghz or 2.4Ghz network, it is basically unusable. Web pages take minutes to load (if they even load at all), dropbox doesn't sync because it can't get a connection and even trying to get to the router config page is extremely slow and hit/miss.

 

Tethering to my iPhone seems to work ok, as does using my home network via wired ethernet.

 

Are any others having problems with Yosemite? Wifi was working fine on Mavericks.

 

Tom

MacBook Pro with Retina display, OS X Yosemite (10.10)

    Hi -

     

    1) I did a clean install of 10.10 - thus migrating nothing (Aside from manually copying over my data)

    2) My Disks (External) had Spotlight Indexes created by Mavericks (Not sure if Yosemite overwrites them completely when installed) - Those I was deleting and re-indexing..

    3) mdworker IS spotlight.. Or sort of - it is the meta data worker which does all the indexing etc. for Spotlight. They come with OS X, regardless of version. And will never be migrated AFAIK

     

    4) I don't have any idea about the .kext stuff. Perhaps some of the savvy ones could chime in here...

    Followup: please open Terminal and enter a "kextstat" command. I'm particularly interested in the com.apple.kpi.libkern version #, yes your library kernel. I'm not very knowledgeable here, but still, this might be something. Comparing library kernel # of Yosemite users with and without the network issues described in this thread. Thank you!

    I'm just joining to note that I have five Macs in my house (a 1 week old MB Air 11", a 6mos old iMac, a 1yr old MB Pro 13, a 2yr old MB Pro 13, and a 5yr old MB 15). I also have a relatively new 20Gb Fiber Optic Internet connection, and a brand new Apple Airport Extreme. So you'd think that bandwidth and routers and what not are not going to the source of my concerns. And these problems occur whether one computer is on at home or all of them are (no difference).

     

    All the computers are running Yosemite, all needed to be updated from Mavericks (even the new one, believe it or not!) and I did not do a clean install on any. All but the newest ones suffer from strange disconnections and freezes since upgrading to Yosemite (Internet connections are insufferably slow, periodically). The oldest one, the MB Pro 15, has the worst of it: if it goes to sleep and we wake it back up, the wifi connectivity is lost. I always have to reboot the computer, otherwise it's not able to send email, can't print to networked printer, etc. On this computer, when I click on the antenna icon, the wifi signal is full strength, but I can see the greyed out text where it should say "Wi-Fi: On" it actually continuously flicks between "Wi-Fi: On" and "Wif-Fi: Looking for Network" (it may be "Wi-Fi: Disconnected," one of the two).

     

    Summary: five computers, one with no obvious probs, three with terribly slow Internet, and one that only works before going to sleep, and requires a restart if it does, in order for wifi connectivity to function.  I maintain all the computers exactly the same way, same software and credentials on each one. With all of that sameness, the variation in performance is astounding to me. I realized today that I was dealing with a clunky, slow system and for the first time since I switched to Macs (from Windows 95) I realized I was dealing with something that was really quite buggy and, sad to say, a bit clunky and hard to manage. Certainly not the silky smooth Mac OS experience Ive been used to.

    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?

     

    Just so people stop going round in circles trying 'fix' after 'fix'. Nothing has worked for me (and I'm the original poster), but as we know, apple have been in contact with myself and others to collect diagnostic info and since wifi is a focus area in the new update, it would suggest that they acknowledge something is wrong.

    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

     

    I
