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

I have bought new Macbook Air 11" Early-2014

Software OS X 10.9.5

but this also has a same problem regarding the wifi. I'm downloading the new software update (Yosemite) about 5 GB and it gets disconnected as soon it goes to sleep.

Did they fix it yet or do we have any solution? Please do something.

And how do I notify Apple about it?

I've been having the same issue all day.

I tried turning off Bluetooth off and changed the "set service order" and it seems okay now, so far. (MacBook Air)

I had these issues but they went away. Just upgraded to Yosemite and all the issues discussed in this post are back.

There doesn't seem to be a fix to this.

Upgraded to Yosemite on MBPr, WiFi is painfully slow

Just incase anyone is skeptical.

Here is the speedtest from my 15" Macbook Pro retina at the corner of my desk:

and here is the speedtest from my 2009 Dell Windows laptop in the same position

Check, your wifi setting and wifi provider. Make sure it is secure wifi or wifi you know is reliable. That being said, visit Apple Store for immediate assistance if this issue persists

I hope that helps. Enjoy your Apple, Inc product.

Wifi network is fine. This is either a hardware issue or a software issue, not a network issue.

However, taking it to an Apple store is a complete waste of time. They simply test it in their own controlled environment, where the router is next to the kit, and everything is Apple ran products.

They need to step out of their own Apple product world

OK, I've concluded that this is 100% a Bluetooth issue, however interesting it would seem that it is only Apple's own products that cause the issue..

Would be nice if anyone else could comment, however speedtests as follows:

Apple Keyboard & Mouse

Just as a final test, I connected my Bluetooth headphones and Nexus phone via Bluetooth, without any Apple devices attached

So the issue is potentially Apples own devices causing interference

I just updated my power saver settings in my system preferences. I set the sleep time to three hours before idle. I don't know why this is an issue but I hope this fixes it. Also upgrading OS tonight...

Hi All

I had this issue for months and it was driving me made, contacted AppleCare and they managed to fix the problem for me.

Go to Sys Preferences / Energy Saver and move the Computer Sleep sliding bar to >>> Never >>>

The 3 buttons below have no ticks in them, not sure if that helps the issue or not.

Just a matter of interest I have a TiVo Tv Recorder and it connects to my Mac via WiFi and for the past few month I keep losing my wifi signal to the Mac after 15 minutes while transferring movies well as of today I have constant connection. Yea.

There are multiple, multiple suggestions for fixing the WiFi disconnection problem that has resulted from upgrading to Yosemite OS. Apple should be embarrassed for not having resolved this matter by now. I've executed two changes in both the Network preferences and in Terminal. Who knows if the last one will actually resolve this matter permanently, and whether it recurs when the next patch is released by Apple. Shame on Apple for this. (I won't be distracted by the company's announcement regarding Mr. Cook's sexuality either. I don't care about that at all frankly.)

Same problem here... Does Apple not care? All they seem to care about is getting us on to the next OS for free so we eventually bog our machine down so much, we have to pay for a new computer. One of the downsides of having all revenue come from hardware... you have to pressure customers to buy new computers.

Is there really no real solution to this? I've done everything. I have to have Bluetooth on due to a wireless keyboard.

Well, after a long time on the phone and deleting all of my preferences, rebooting, etc. The problem still occurs. After my rMBP sleeps for a while (over night or during the day) waking it back up will end up with a network that claims it is working but not working. No packets will go in or out but the connection claims to be live.

I have run the wireless diagnostics tool while it was in this state and it could not figure out what is up.

The only way to get the connection back is to turn WiFi completely off and then back on again.

I really hope that this can get resolved soon. It is just very annoying.

It is not a bluetooth issue its a dual band router issue.

I gave my 2.4ghz and 5ghz wireless bands different names (SSID's) so I had seperate wireless connections to connect to.

On the 5ghz network 'uncheck' the sync with 2.4ghz or select no.

Change the wireless SSID name (I just added 5ghz to the end of the original) Voila

You will have to reconnect any dual band devices to both the 2.4 and the 5 wireless networks.

Happy days.

Ok this is very random but worked 100% so far.

My wife has imac i have Macbook Pro...

We moved house 12 months ago set up everything but not apple tv.... it was plugged in but didnt set network.... in june we came back from holiday and i set up network for apple tv....few days later my wifes WIFI stopped working, she put her imac into sleep and wouldnt get connection after like it seems everyone here..... nothing worked. My macbook fine as i didnt put it to sleep.

SO we never use apple tv although connected but never turned on... my wife continued to have same problems as everyone here.. i was fine as were all the other devices.

Few weeks ago we had some bad lightning and the wifi box blew up so a new one was purchased, my wife connected to the network as did i and as did 2 ipads 3 iphones... no issues... MY WIFES imac worked perfectly..... Like MAGIC

Yesterday i started apple tv put it on the new network no problems all devices and mac book and imac perfect...

Today i put my macbook to sleep when my wife Unbeknown to me was watching APPLE TV ( NETFLIX) i started it again after about 20 min and the issue was anightmare... same problems as everyone on here... my wife started imac from being turned off and no issues....

SO HERES WHAT I DID.... i turned apple tv OFF turned it back on again nothing changed i still had issues...I THEN DISCONNECTED APPLE TV from the NETWORK and let it turn off.... i came to my laptop restarted it from shutting down and guess what? no issues whatsoever...

SO FOR ME the issue is with APPLE tv on same network, surely this is why it only affects some macbooks not others.... also im running yosemite and as i say never once had an issue until today when i put macbook to sleep with apple tv on...

FWIW I also have this problem, exactly as described by many others. I have a new macbook pro 13 retina, and Yosemite latest.

I've notice software quality control at apple is not what it was... My 17in MacBook Pro unibody was a workhorse, never had any trouble. I wish they'd bring it back 😟

I've been going Mac for a while since as a software developer I need stuff to just work. If I am going to be forced to mess around with settings I may as well use ubuntu.

One thing I can't figure, anyone know if this is a problem if you have a latest Apple branded wifi access point? I was thinking of trying that and just using my current router as a DSL modem.

Zero issues with wifi in Yosemite with an Apple TimeCapsule (4th generation). Feel sorry for all that's having problems. 😟
