    Same issue here. I have macbook pro (retina display) Mid 2012. Wifi was connecting seamlessly in Mountain Lion and since I upgraded to OX X Mavericks, its it unable to sense wifi during startup or wakeup. I have to go through the process of disabling and re-enabling the wifi and then select the SSID from the drop down. Very frustating... I have tried resetting SMC and PRAM but still no luck. What gives?

    ok so the ONLY solution is to turn off bluetooth. THIS IS NOT ACCEPTIBLE APPLE! but for those of you (like me) who dont use bluetooth regularly, then turning it off will suffice till APPLE SORT THIS ISSUE OUT! annoyingly, my friend with an older mac air (2102 model) does not have any problems with new mavericks!

    Nope turning off Bluetooth doesn't work anymore for me. It came back after a few days. I'm very frustrated.

    Turning off iCloud Keychain worked for me, on every computer with which I had issues.

  • Steve Traut Level 1 (5 points)

    My issue is gone now... consistently over about the last week. The only thing I did was reset the SMC. I still use bluetooth daily to connect to bluetooth speakers.


    I have noticed that iStat Menus still reports my IP address as being from the wrong network (not updating as I move) but at least now when I check the actual network system settings, both wired and wifi IP addresses seem to change as they should as I move between my home and work networks.


    Just my observations on this so far... your mileage may (and probably will) vary.

    same issue here. no auto wifi connection when waking from sleep. issue not present upon start up.

    brand new MBP 13" w/ mavericks.


    - tried resetting PRAM and SMC - no luck

    - tried deleting all networks, disabling wifi, re-adding network - no luck

    - tried deleting some specific pref files - no luck


    going to try disabling bluetooth and then keychain if no luck.. #crossingfingers

    The iCloud Keychain is actually most likely the culprit here. Wifi worked fine after installing Mavericks. It wasn't until I added a new network (activating the iCloud keychain) that any issues appeared. Although, I'm not happy about having to disable the iCloud keychain, I may do it. ... Why did I upgrade again?

    We seems to be hundreds customers all arround the world having problems with wifi on Mavericks and apple is actually ignoring us. We try to make this problem visible to apple with the tag #macwifiloss on facebook and twitter.


    I bougt a brand new 15.4" macbook pro one week ago and I never succedeed in being connected more than 20 consecutive seconds. So I bought a thunderbolt to ethertnet adapter, and I have exaaaactly the same problem.

    I tried all the fixes I saw on different forums and it changes nothing.



    I have a macpro and my old mbp 17" mid 2009 connected on my local network. The weird thing is that when I connect my late 2013 mbpr he is recognized even if my wifi or ethernet connection doesn't work on worldwide web : I can't use safari that says I'm not connected but I can share files.
    I tried to share folders of more than 100go, and it works with my top wifi rates during hours, but still impossible to go to internet.



    So for those who still have wifi problems like don't forget to use the tag #macwifiloss

    Turning Bluetooth off has resolved for me. Yiiiiiiihaaaa

  • iharosi Level 1 (0 points)

    Turning Bluetooth off is the only way for me to get rid of this annoying "loosing wifi after wake up from sleep" problem.


    I'm sure Apple screwed up something with the new Mavericks OS.

    Sometimes the external display stops working after waking up from sleep. WTH?!

    This is going to happen all the time when Apple releases a new version of OS X? I'm really sick of it. I've just bought a new haswell rMBP 15", I spent a lot of money and I've got a beautiful laptop with a lot of software bugs. Great!

  • David in Germantown Level 1 (45 points)

    Same problem with same brand new rMBP and same solution.  Turn WiFi off then on and internet connectivity returns.  WiFi signal is strong, full 5 bars.  Putting the new rMBP to sleep, closing lid, and it loses internet connectivity (until I recycle WiFi).


    Apple, can you hear us?  Please FIX THIS SOON!

  • celtictricky Level 1 (0 points)

    They really need to step to the plate with this and resolve it.  Also notice it does affect IOS devices to in my instance.


    Very disappointing.

  • iharosi Level 1 (0 points)

    Oh. I forget to mention. My iPhone 5 can not be able to pair with my rMBP through bluetooth since Mavericks. Now it's useless. I can not share my mobile net with my Macbook. Bluetooth is useless.


    Shame on you Apple. Not because you have bugs in your operation system but you do not have even a comment about it. :-(

  • DaverYYC Level 1 (0 points)

    My new MacBook Air was effected by this problem (but the old white MacBook was not).  Here's what I did 2 days ago in System Preferences in this order: renew DHCP Lease, uncheck Keychain in iCloud, and then restart the computer.  So far so good. Expecting a legitimate update sometime soon from Apple

  • celtictricky Level 1 (0 points)

    Afraid this did not work for me, but it was worth a try so thanks for sharing.
