OS X - Fix for wifi disconnect after suspend/resume

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

Uninstall:

I received the following errors when attempting uninstall:

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

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

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

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

Finished installing Wifi/BT fix

Now try to suspend and resume your Mac, your wifi should connect without issue

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:
