Jul 8, 2014 2:54 PM in response to Celatumby aysm?,Celatum,
It's possible that either this or a previous update did not install correctly. You may find some useful info in Console, but if you want, it may be easier to just try reinstalling the update - it won't hurt anything to reapply the update. You can download it directly at OS X Mavericks 10.9.4 Update for the small download (identical to that in 'software update') or OS X Mavericks 10.9.4 Update (Combo) for the larger combo updater (which might also fix previous updates that failed to install correctly.) Of course, there may be another problem that needs troubleshooting; but this is a good place to start.

Jul 8, 2014 3:27 PM in response to aysm?by dinlo21,Ok... From my last post saying the world is fixed, it's broken again.
Apple guy pretty much said they know about the problem, it's software , to wait for next major release...
Sorry I didn't come beating more expedient news.

Jul 8, 2014 3:40 PM in response to dinlo21by aysm?,10.9.4 update was released last week on 30 June, 2014. It looks like your previous post (about deleting com.apple.Bluetooth.plist) was before the release of 10.9.4. Have you tried the new 10.9.4 release? If so, was there any improvement or did you notice any new symptoms?

Jul 8, 2014 11:21 PM in response to dinlo21by MichaelSinz,BTW - I have fixed it for me. The final trick that really worked on my rMBP was to turn off the "Wake for WiFi network access" in the Energy Saver system preferences. After doing that I really no longer had the problem of the WiFi not working after coming out of sleep.
My guess is that the little bit of life that they have to give the WiFi hardware to support the wake-on-network behavior is confusing the sleep wakeup states and some times/many times causes the WiFi problem. All of the other "delete this preferences file" "fixes" were just the random chance behavior of the system showing up after someone made some change that seemed to "cause a fix" when it really was just "luck" that it seemed to help.
(Since the bluetooth radio is related to WiFi chipset it is likely that there was some minor interaction there but it really made no significant difference.)
I have yet to play enough with the latest update to see if it works with wake-on-network behavior for the WiFi network. I would hope it did but right now I would rather doubt it.

Jul 9, 2014 5:08 AM in response to aysm?by Celatum,Hi aysm,
Tanks for your reply. I tried the big combo re-upate and nothing has changed.
Apple and I have tried every trick in the book over about six months. Thirteen visits to my local Apple store have cost me diesel and tyres and depreciation on my car for 975 miles. Thirteen times I have had more than half a day off work and paid £3 to park. On one visit I had an attempted crash for cash incident to deal with. I have heard all the advice to delete the caches and all the learner-book one stuff.
I have had five brand new replacements for my original 8gb MBP and then they gave me a sixth brand new replacement, the 16mb - it connects differently, apparently. This had a reduction in the frequency of the problem but still forgets connections perhaps a dozen times a day. The fifth brand new replacement didn't even make it out of the store, they had a meeting in the corner and gave me the 16mb there and then. I have just been too fed up to go any further.
Yes, we have isolated my home network, we have made a dedicated custom airport express network for a brand new MBP straight out of the box with no data on it at the Genius bar put it to sleep for ten minutes and it forgot the network - oh, we did reinstall Maveriks first, in case the brand new computer was corrupted. The top man from upstairs was looking at pages and pages of code until smoke was coming out of his ears.
The problem is software and Apple have not fixed it; I don't know why they think they have.

If PC stands for "Propelled Cemtex", I will take my MBP to the bottom of my garden and fire some at it.

Jul 9, 2014 11:47 AM in response to Celatumby dinlo21,No problem… FYI - updating to 10.9.4 has fixed the problem.. Will monitor for a while and update if it changes.

Jul 9, 2014 12:25 PM in response to dinlo21by Celatum,Hi dinlo21,
I'm glad it has fixed yours. I would do anything to have a computer that just does what is supposed to do. I'll eagerly wait for 10.9.5 or .6 or .7 or whenever Apple globally fix the problem. The first thing they have to do, which they are slow at, is acknowledge that they only have a random fix. That suggests that they do not completely understand the problem, which does not encourage me much.

Jul 16, 2014 1:33 AM in response to dinlo21by samthebear,Hi All,
I last posted on this following an upgrade to Mavericks on my MBA. The only work around that worked for me back then was the Bluetooth dance of on.off/in.out/shake it all about.
10.9.4 seems so far to have solved the problem with my machine as well.
Incidentally, I had a play on someone's Windows 8 machine the other day and can confirm that within 10 minutes of trying to install a printer and it subsequently breaking wifi and a few other things - the grass isn't always greener

It did not fix it for me on a 2011 Mac Book Pro.
