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

Tried every single idea in this thread; none work.

And it's realy annoying to have to wait minutes after opening my macbook, of constantly turning wifi on/off...

*SIGH*

Same problem here, nothing helped. Except it's a new machine (old stock 2012 MBA) and I have tried also a clean re-install. Here are the details:

Yeah scratch my thoughts on DropBox. With DropBox uninstalled, my machine slept overnight and when it woke there was no network connectivity. Removing DropBox seems to just make the issue occur less frequently. It's a Mavericks issue, as I never had the problem on 10.8. Hoping for a patch soon from Apple.

My problem is that when the computer has gone to sleep (open laptop), when I wake it, the wifi isn't connected at all and isn't searching for a connection. I haven't had the issue of it taking forever to reconnect; all I have to do is click the menu bar icon and grab my network as soon as it finds it. I messed with the energy saver settings the other day but it doesn't look like they stuck. "Put hard disks to sleep when possible" was checked again, and I'm pretty sure I unchecked it.

This is the one that worked for me. I turned off bluetooth and the next wake from sleep immediately found and connected to WiFi.

After doing all suggested by rogerfromwilrogerfromwil, initially my wifi still cut off. But, surprise, surprise it now works like it used to do. Comes on everytime i wake it up!! Also have turned off Bluetooth.

Thanks but I'm not sure what worked!!

Another thing I did but failed to mention is under schedule on power savings, I set turnoff to 11PM and wakeup to 7 AM which is good for my schedule.

I can't turn off Bluetooth on my machine; my only keyboard is the Apple wireless one.

Turning bluetooth off did it for me too! Thank you, thank you, thank you!

This problem was extremely annoying, I can't believe Apple can't sort this thing out, I don't want to have a choice of either wifi or bluetooth, I want both!

Same here, this is getting extremely annoying

My problem started when I turned on Bluetooth the other day.  What fixed my problem was from a previous post in which you

launch System Preferences

select Network

click on the gear in the lower left corner

select Set Service Order

click and hold on Bluetooth and pull down and below your WiFi (what ever name you gave it)

click OK

restart

close your laptop lid for a minute and reopen... 

WiFi connected right up

I'm guessing the computer is trying to connect to a Bluetooth device and caused the WiFi to time out befor it connects to whatever Bluetooth device it's looking for....

Hope this helps,

Mike

I reset my NVRAM and SMC and this fixed the issue for me. The first time I woke my MacBook Air from sleep after resetting the NVRAM and SMC it asked for my WiFi password. After entering it, now everytime I wake from sleep it's instantly connected and all applications are communicating with the Internet that were left running.

This didn't seem to work for me unfortunately. Especially long sleeps like overnight, even with the bluetooth at the end of the connection list it seems to interfere with my WiFi. As soon as I turned off Bluetooth, again WiFi functions and connects immediately.

The same for me. I've tried everything, which I have explained in my previous poist and invested a lot of time. I did also suspect other apps like Dropbox have something to do with it but fail. Also the WLAN location services order did not help.

I did also not get any other infos from Apple Support, the recommended way was that, after investigating all other possible failures, to do a SMC, PRAM reset, OSX re-installation. None of them really helped in my way.

I went also back to Mountain Lion but I got the issue there too...very frustrating, since it was running fine there before. Now I am back to Mavericks.

In the long term, as mentioned by antipoet, nothing helped, only doing a reboot. The last thing which I have on my list is, to make a "real" new fresh installation, creating a bootable memory stick and then erase the whole HDD, and then install really new http://www.macworld.com/article/2056561/how-to-make-a-bootable-mavericks-install -drive.html

However, since this is a lot of work, I will wait with this...hopefully there will be a patch before with a fix. I don't know if Apple is aware of this issue and keeps track on it...no one will ever tell for sure :-)

Well, I have to apologize...  Moving bluetooth to the lower position didn't work after more testing.  The only way that WiFi fired up and connected right away was if Bluetooth was Turned Off !

I have a 6 month old Macbook Air and after upgrading to Maverick and turning on Bluetooth this WiFi problem poped up....   We'll have to wait for an Apple Update...
