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

Have tried all fixes in thread -- wifi still dying when bluetooth is on. 😠😢

THe plist solutiuon only works temporarily. It will become corrupt again. On my late 2013 rMBP, the triggering event is when I am connected to a bluetooth speaker and the computer goes to sleep then the speaker is turned off while the computer is sleeping. When the computer wakes, it will now fail to connect to wifi and will fail every subsequent time it goes to sleep and wakes. If I delete the bluetooth plist the problem is fixed until I turn off the BT speaker again while the computer is sleeping.

After fighting with Apple Care for 3 months over this issue, I finally convinced them to replace my machine. Brand new computer arrived the other day and right out of the box I get the same problem. I called Apple right away and they are now assuring me that this is a known OS X issue that will be fixed in the next update. Sounds good, except they told me the same thing before 10.9.2 came out. But at least replacing my maching proved its not a hardware issue.

The one thing no one can understand is why the computer works just fine if I am an an Apple network. As soon as I go to a non-apple network I get the problem.

So far toggling the bluetooth is the only solution that works! Thanks!

I've experienced exactly the same: deleting bluetooth plist (and rebooting) fixes the issue but it comes again when turning off a paired bluetooth device while computer is sleeping.

I think we have the problem surrounded, which is surelly a software problem.

thanks

Not to be a bummer, but I think some of us have had the problem surrounded since like 2006 (Tiger'ish timeframe). I'd be curious, now, if anyone is here where this problem didn't exist until the 10.9.2 update. The Apple rep who told someone earlier that this is new with Mavericks, probably hasn't been around all that long (I didn't have the problem while on Snow Leopard, and didn't use a laptop much for Lion or Mt. Lion, but didn't notice the probem there). It might be new to Mavericks THIS time aronud! A problem with BT being enabled causing WiFi to fail, and disabling BT before sleep being the fix, has been around on and off, like I say, since Tiger.

While there are people with genuine hardware problems, the core issue here is cleraly not hardware.

And again, in my case, it was a brand new MacBook Air, with Mavericks pre-installed. Everything was fine until I added ONLY an Apple BT Mouse.

I am, and pretty much always have been over the years, using a non-Apple WiFi router, whether at work or at home (and, that isn't going to change, so if that's the cause, Apple still needs to fix it. My routers, at work or home, have been the very best and most popular models, such as Linksys WRT54G or now, ASUS RT-N66U.... and I think Cisco at the Fortune 100 I worked for).

The problem magically disappeared with the 10.9.2 update, but I'm sure it will be back at some point, unless Apple REALLY finds and fixes the problem.

Try resetting Energy saver in System Preferences to factory default levels. Might help?

I'm having the same issue (late 2010 & 10.9.2) with my MBA also. If bluetooth is on, and the device is nearby, then the network is disconnected and takes 1-2 minutes to reconnect upon awaking. If I'm away from home (and the magic trackpad isn't in the area) then the network is instantaneous upon awaking. If BT is off completely, no problem at all.

Apple, any ideas here?

Just had a thought. I hadn't noticed too many problems since I deleted the plist and left my BT headphones unpaired (leaving only one BT device - numeric keypad - paired). But this morning the problem reappeared. I think it might now be occurring only when the MacBook goes to sleep with a program running. Can anyone confirm this?

Just adding myself to the thread of people who are experiencing this issue. I have a late 2013 MacBook Pro Retina that I use with the Apple Bluetooth Keyboard/Mouse. When Bluetooth is turned on the WiFi takes a long time to connect and when it is turned off it connects quickly like my old machine did. Hoping a fix is found soon.

I didn't read the whole 17 pages but wanted to add my experiance. I have had a MBA since the second version and travel with it extensivly. It is usually open and closed many times a day. Since I have owned the MBA's (this is the 3 one) I have never had a bluetooth device untill a few weekes ago. I bought an Apple display and got a keyboard, mouse and touchpad.

This is when I noticed the issue or reconnecting. Makes sense now that it is chunking on those peices being gone and trying to connect to them...shutting off BT works well when I am traveling at least. It would be nice if they fixed it. Waiting for the reconnect when BT is on is a pain.... 😟

I read through this post and all the possible solutions, However none of them seem to work. Until I found the following:

1. Go into settings/network and select Wi-Fi, Then click advanced.
2. Under Wi-Fi, delete all preferred networks.
3. Click OK.
4. Click Apply.
5. Close settings.

Open Finder window to Computer/Macintosh HD/Library/Preferences/SystemConfiguration, and delete the files named:

• com.apple.airport.preferences.plist
• NetworkInterfaces.plist
• preferences.plist

Empty the Trash, and reboot... After that you should be $$$!

GOOD LUCK!

No this only solves the problem temporarily. The problem will return as soon as you put the computer to sleep while connected to a bluetooth device then turn the bluetooth device off while the computer is sleeping.

There are only 3 surefire "workarounds" to solve this problem:

1) Keep the computer plugged into the magsafe power source when it sleeps.

2) Turn off bluteooth before it sleeps

3) Use an Apple Airport Extreme router with the 802.11ac technology

Hi all,

after sometime of noticing this, I decided it was time to find a way to solve it and came accross this post.

I didn't try the Bluetooth or changing router solutions as I don't consider them as options. I did have an idea though to remove all wireless networks except the 2 that i use. I have an iMac 27" mid-2010 so there is not really a change in my wireless. Anyway when i tried to delete from the list of wireless the ones i don't use, I noticed that some of them I have never used with either the current iMac or my previous MBP that I migrated my stuff from, but only through my phone. When I tried to delete them it asked me if I was sure that i wanted to delete that network from all devices. Thank got me thinking that wireless too is connected to iCloud services (didn't know about this).

So i just moved the 2 wireless networks at the top of my preference list just in case and opened iCloud services in Settings. There I have everything ticked but the only one that I have no use is the "Back to my Mac". I don't know how to use it plus i get an error when I try to enter its settings, so I unticked the box.

Then testing came with sleeping my iMac and waking after a few minutes with the WiFi On and connecting almost instantly in <5sec. As I said, didn't touch the Bluetooth at all as both keyboard and trackpad are using it.

Please try this as well and report back if it works for you.

"1) Keep the computer plugged into the magsafe power source when it sleeps."

Does not work for me. Setting sleep while on AC to one hour helps but being tethered to AC and not allowing the machine to sleep defeats the purpose of a laptop.

"2) Turn off bluteooth before it sleeps"

Turning off Bluetooth period works for me but that's not an option.

"3) Use an Apple Airport Extreme router with the 802.11ac technology"

Have not tried this. Not willing to spend the money to experiment. I should get what I paid for.

The only thing consistent about this issue is when someone thinks they have a good work-around, it turns out they don't. It always comes back to the same issue: with Bluetooth off, Wi-Fi automatically connects. With Bluetooth on, Wi-Fi usually does not automatically connect.

Most started seeing the issue since Mac OS X 10.

Probably I've found the reason of this annoying problem and I've found a solution too (at least it worked for me).

Thanks to people of this thread that found that the wifi problem is connected to the bluetooth activation. They gave me the right idea that I followed to find the solution.

The problem is due to the "Order of services" in the Networking Preferences (sorry for my translation but my OS is in italian so I'm guessing how the option menu could be in english). If the DUN Bluetooth or PAN Bluetooth service is BEFORE the Wi-Fi service, after waking up your Mac, your Wi-Fi will reconnect very very slowly or will never reconnect automatically at all.

But if you change the order of your Networking Services and you put the Wi-Fi at the first place, your Wi-Fi will reconnect almost immediately (it worked for me!).

To change the Networking Service Order go to Preferences --> Network, press the Gear Wheel in the lower left of the window, choose the "Set Service Order..." option. A new window will appear with different kind of connections.

Drag your Wi-Fi connection to the top. Press OK, and then Apply.

Restart your Mac and verify by yourself if the Wi-Fi problem has been solved.
