Q: Wifi disconnects after sleep and takes long time to reconnect with Mavericks

Update - My Macbook Air is sometimes taking a bit longer to connect than usual, but 'knock on wood' it still always connects on it's own (I'd say 10-15 seconds max when it does it, and maybe 1 in 10 times it wakes from sleep for frequency).

But, come on folks. While I understand the frustration, there needs to be a dose of reality here too. Having worked in IT for almost 25 years now, this is a fairly minor problem... especially if you've spent any time working on other platforms. Having to turn the WiFi off and on, or turning off BT before sleep is a pain, but it hardly makes the machine unusable.

@ JRFINN - I'm not sure your problem falls under the primary one described in this thread. If your WiFi is suddenly being lost, something else is up. The issue we're primarly talking about is that after adding a BT device, WiFi doesn't always *reconnect* on wake without 1) turning wifi off, and back on, or 2) turning off BT before sleep (which obviously won't work for desktop folks with BT mouse/keyboard).

My experience of this ...

Macbook pro retina, purchased spring 2014. OS 10.9.2

Fault - wifi working fine until sleep, on rewake failed to reconnect, manual select of wifi network needed.

Solution 1: Turn bluetooth OFF. Wifi works fine, reconnects fine. No bluetooth (obviously)

Solution 2: (From jsalord on p.8 of this thread)

1. Open Finder -> Go (menu) -> Computer -> Macintosh HD -> Library -> Preferences

2. Delete file: com.apple.Bluetooth.plist

3. Reboot computer

For me, solution 2 works fine. Wifi works. Wifi reconnects. Bluetooth works.

Will post again if I have any problems.

Posted in error.

Update: My Apple Support guy called me back today. He had no further suggestions but said he would again report this to the engineers. He said it definitely is a Mavericks problem. I told him I had read of people having the same problem before Mavericks, but he said those were always specific to one type of machine (iMac, etc.) If I delete the plist file and restart, my Bluetooth keypad is still on the device list, and it does not seem to affect wifi. Wifi works fine as long as I don't pair my second BT device (headphones - the trouble started when I paired these last week). I don't really need them, so I will count my blessings and do without them until Apple comes up with a fix.

Maybe there is some specific bluetooth connection type or wi-fi router that is common to people with this problem. I have noticed a lot of people on the thread mention that they are using bluettoth to connect to some audio equipment (myself included) like headphones, speakers, etc... And also, someone mentioned that they have had a workaround from using a specific wi-fi router.

Perhaps if we all list these specs when we post, we will notice a pattern (wishful thinking I know, but I am frustrated) that could help Apple fix this.

So, I have Comcast Xfinity router. And I am pairing to mouse, keyboard, Jambox, iPhone.

I just got off the phone after two hours with Apple support; I was escalated 2 or three times. At the end what fixed my problem -- I THINK -- was deleting the Bluetooth plist file. The things we tried that did not help included:

- resetting PRAM

- repairing disk permissions and disk drive

- booting into safe mode

- deleting networks and readding them

- deleting wifi as a service entirely and re-adding it

- creating a second admin user and booting into that account to see if that worked

- resetting SMC (think that's what it's called)

- trying different networks (problem happens with all wifi networks)

Turning Bluetooth OFF did fix the problem, but that's obviously not a good solution. Fingers crossed this helps!

I have a Mac Book Pro from fall 2013 running 10.9.2.

That's a great idea, Rudy. In my case, the culprit seems to be the second Bluetooth device I paired to my MacBook, the GOgroove AirBand Stereo Headphones. The first BT device I paired, a Satechi Wireless Smart Keypad, does not cause any problems.

I can pair the headphones without any ill effects, but as soon as I actually use them, the no-wifi-after-sleep problem starts. Deleting the plist file makes it right again.

I believe it's been mentioned here before, but the audio devices are not the issue. Also, deleting the plist file will only temporarily fix the problem; it will come back.

Personally, I only have the Apple Magic Mouse, an Apple keyboard and an Apple touchpad paired, so 3 devices and all from Apple.

My situation is very simpel:

• Bluetooth turned ON: slow wifi reconnects, usually takes 30-90 seconds before it connects to wifi, sometime not at all and I have to turn wifi off > on.
• Bluetooth turned OFF: everything normal, wifi is connected almost instntly after waking up.
• Deleting the bluetooth plist file helps, but within a day the problem returns.

Although I'm not saying that audio devices are necessarily to blame, I do know that I used my Bluetooth keypad for a couple of weeks after getting my MacBook Pro, and had no wifi problems. As soon as I connected the second BT device and used it (perhaps just a coincidence that it was headphones), the trouble started. It is my understanding that deleting the plist wipes out the BT pairings, but maybe I'm wrong about that. After plist delete and restart, the headphones are absent from my BT devices list, but the keypad is still there and functioning. No wifi problems even after overnight sleep. The Apple Support tech said that perhaps the keypad does pairing differently and hence automatically shows up again on the devices list even after the plist has been deleted. I'm not qualified to give advice at this point; only reporting what's happening here. Thanks.

Hmm... maybe the problem starts when 'two or more' devices are paired...? It might work with one device paired, but I can't test this, cause I have to use all 3 of my devices during a days work

Yes, you read my mind. I have an Apple keyboard that I use with my iPad, and I was thinking of pairing it to the MacBook to test that theory. Common sense tells me to leave good enough alone, but if I'm feeling daring later I'll let you know what happens...

My bluetooth devices were:

Apple mouse (no problems)

Went to work, paired with bluetooth speakers.

Came home, problem started.

Deleted bluetooth plist. Problem fixed.

I notice that the list of paired devices now only has the my mouse, not the speakers. Tempted (but not that tempted) to re-pair the speakers and see if the problem comes back.

My bluetooth devices are: Apple Keyboard, Apple trackpad, H800 Logitech Headset, UE mini-boom.

When home, I have an Airport Extreme router and can use any or all of the 4 devices and never have a wake from sleep problem.  When at work we have a non-apple router (not sure the make), but I only ever have the keyboard and trackpad connected (the UE miniboom and Logitech headset are not even in the building).  And I consistently have the wake from sleep problem unless I turn off bluetooth.  NOTHING else in this thread is any kind of fix for me. 

Am I right in assuming that there is a single chip that does both bluetooth and wifi on  an Early 2013 15" Macbook Pro?  Seems pretty likely there is a problem with that chip that affects my system when connecting with non-apple routers.

I can't answer your question; just wanted to throw in that I have a Buffalo router, so my experience is in keeping with your suspicion that this problem exists only for users of non-Apple routers. I don't have time right now to re-read this whole thread. Does anybody know whether this problem has been reported from a user of an all-Apple setup? While she has not mentioned the wake problem specifically, my daughter has talked about intermittent wifi problems with her MacBook Air here and at school, both locations having non-Apple routers.

To summarize what I have found so far:

Issue is that wifi drops after wake from sleep, and also that it drops randomly while surfing/idle

Issue is happening on OS Mavericks MBA and MBP (may also exist on Lion and Mountain Lion)

Issue is happening on on wifi (may also exist on ethernet connections)

Issue may be also related to wifi router, but some users have successful connections to other apple products including ipad, ipod, etc and windows laptops

Issue has been reportedly resolved using Reforgers method  https://discussions.apple.com/thread/5537854?start=0&tstart=0

Issue has been reportedly resolved by turning off Bluetooth completely (or by just turning off Bluetooth PAN)

Issue has been reportedly resolved by turning off iCloud services

Please give apple feedback!

100K people have read this and other threads, if all of them leave a quick feedback maybe apple will fix/respond.  Even if a temporary fix works it is not a full solution and apple should push an update
