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

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

Probably I've found the reason of this annoying problem and I've found a solution too (at least it worked for me). The wifi problem is connected to the bluetooth activation and 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.

Vladimir_33 try going to Energy Saver & uncheck 'Wake for network access'. This solved it for me on both a new rMBPro and a new iMac.

Words cannot describe how angry this problem makes me. How can world's largest tech company not been able to fix their biggest bug for this many months now?!?!

All these forums are overflowing with the same **** problem: WIFI DOESN'T CONNECT AFTER COMING BACK FROM SLEEP ON MAVERICKS.

How many thousands of people have to post the same godddamn problem for how long?

And no, disconnecting Bluetooth doesn't work (even if it did, its not an acceptable solution). I took my MacBook Air to Apple store twice already and they cannot help either.

aaaAAAAaAaaAAaaarrrrghhh, I'm going to go insane from this problem.

I miss Steve.. he wouldn't let something like this go on for this long. Can a half a trillion dollar company pay attention to its own support forums or at least google "wifi-not-connecting-after-sleep-mavericks" and realize what incompetent company you have become?!

I have tried and better tried to to get this sorted but the impression i get from apple is that they genuinly dont give a toss about there customers or there problems.

Dear everyone buying a macbook air. Don't bother. They are faulty and apple dont give a toss.

thank you. seems to be working so far..
