Q: OS X - Fix for wifi disconnect after suspend/resume

OS X - Fix for wifi disconnect after suspend/resume

 

I've purchased a Mac recently and since upgrading to Maverick have been having some problem with wifi after suspend/resume. Looking into the issue, I've found this thread: https://discussions.apple.com/thread/5495375 and some people have reported that turning off bluetooth did fix the issue.

 

For my case, this was not possible, so I've tried to make a little fix, that disable bluetooth on suspend and enable it on wake, but with a 10 seconds delay, in order to let the wifi connect successfully.

 

Here is my github repo for anyone to look at the code: https://github.com/Setsuna666/osx-wifibtfix

 

Here is the latest version of the fix, which include an uninstall script: https://github.com/Setsuna666/osx-wifibtfix/archive/v1.0.2.zip

 

If you have any questions or issues, please post it here so it can be easier for me to keep track of.

    Setsuna, thanks for the work on this, sounds very promising.  I will backup, attempt it and let you know my results (both initially and after several days of it running)

    What I did:

     

    Note: since I believe it matters, the order of my network connections are (this is default after you delete system preferences in /Library/Preferences folder:

    Bluetooth DUN

    WIFI

    Bluetooth PAN

    Thunderbolt

     

    Tried to reproduce the error:

     

    Put laptop to sleep with Bluetooth on, upon wake it takes approximately 15 seconds to connect to the internet. This is not the severe case in which it never connects to the internet and which you have to disable/enable wifi and maybe select the wifi source to reconnect.  So to reproduce that issue, I connected to a BTdevice (bose speaker), unpaired the device and restarted my machine.

    Now when waking from sleep I cannot connect to internet.  So I employed the plist fix by removing those system preferences.  Now I can connect to the internet but it takes approx. 15 seconds to connect to the internet (hangs and eventually brings me to the website of interest).  Then I DL your fix:

     

    DL source code. 

     

    Install with sudo bash install.sh > suggest adding a set.exe/dmg that they can run because most users will be baffled by cmd line haha, and make the readme a .txt, not sure how to run .mg file myself

     

    1) Shut laptop into sleep and waked with Bluetooth off –

    -instant

     

    2) Shut laptop into sleep and waked with Bluetooth connected –

    -instant

     

    3) Shut laptop into sleep and waked with Bluetooth unpaired but still in devices list–

    -15s

     

    4) Restarted System

    Connected internet with BT on but unpaired

    -instant

    Laptop to sleep and wake

    -15s

     

    5) Shut laptop into sleep and waked with Bluetooth connected –

    -webpage not connected, reload worked

    -instant

    -instant

    -instant

    -not connected, reload worked

    -instant

     

    6) Shut laptop into sleep and waked with Bluetooth off –

    -instant

    Uninstall:

    I received the following errors when attempting uninstall:

    Uninstalling blueutil...

    rm: /usr/local/bin/blueutil: No such file or directory

    Uninstalling SleepWatcher...

    rm: /usr/local/sbin/sleepwatcher: No such file or directory

    rm: /usr/local/share/man/man8/sleepwatcher.8: No such file or directory

    rm: /Library/LaunchDaemons/de.bernhard-baehr.sleepwatcher-20compatibility.plist: No such file or directory

    Stopping SleepWatcher...

    No matching processes were found

    Uninstall finished

     

    Verdict: Fix appears to improve reliability and usability over not having the fix and having Bluetooth off, however, it seems at this point for me it is better to just turn Bluetooth off (because Bluetooth on my laptop is not critical, I can use ipad for BT music playing)

     

    Summary of Results:

    Install works

    Uninstall does not work

     

    Recommendations:

    Make the installer/uninstaller a .dmg file for click and load

    Make readme a .txt

    Fix uninstaller if possible, looks like it cannot find the files

    Improve results when BT not connected  (the 15s delay) if possible

    If the uninstaller doesn't work, it might be because the installer didn't run properly. What it does is remove the files from where it has been installed.

     

    Will try it again to make sure, but from my tests it was working correctly.

     

    Thanks for the feedback.

    Other people, please try this and give feedback!  There is literally no risk if you backup your system

    (Time machine is great and easy, and Disk Utility - Image backup works too).  The more people try this the more we can verify it and improve it.  And! if it works we can suggest it to Apple as a fix that they can rollout through updates

    I doubt Apple would add this as a fix through their updates system since it is more a hack than an actual fix.

     

    I'm sure they can manage to fix it properly.

     

    The more people testing it, the better :)

     

    Thanks

    Does the readme specify a location to run the installer from?  Can it be run from anywhere? Wondering if mine was not installed properly amd hence not uninstalled properly as you suggested

    You need to download the zip file and run it from the extracted folder.

    I guess it may be issues with the installer that caused the uninstaller to not work.  See the output of my running:

    Oh, I see the issue. Will look into this and post a fix.

    Installed properly this time:

     

    It appears to work, when I resume from sleep the Bluetooth icon is off (gray) and wifi connects, after 10s Bluetooth icon comes on again. 

     

    Here is the correct output:

    However, when I try to reinstall, I get a proper output, but it does not seem to work anymore, which makes me think the installer/uninstaller are not working together properly.  The reason I say it no longer works is because when I wake from sleep bluetooth does not automatically come on (gray-Black) as it used to.  Here is the output from the re-install:
