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

Since upgrading to Mavericks whenever my MacBook Air goes to sleep (if I leave it idle) the wifi disconnects and it can take up to a minute to reconnect when it wakes.


Basically what happens is, as soon as it wakes I have no internet connection, the WiFi indicator is pulsing, meaning it is searching for networks, but it takes ages to find any, then after some time, usually between 30 secs and a minute all the networks in my building pop up and it instantly at that point reconnects to my WiFi network.


It is incredibly frustrating I was so used to the Mac being an instant on tool, now it takes longer to get on the internet than booting up my windows PC.


Any ideas what might have caused this?

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.

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

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...
