10.9.2 slow to reconnect WiFi after sleep?

    I've noticed since I upgraded to 10.9.2 on my 2011 MBP, whenever I wake my laptop up from sleep (open the lid and type my password), the WiFi icon on my menu bar is greyed out, and it takes about 10-30 seconds to reconnect to my WiFi network. During that time, the 'rainbow' icon indicates that it's connecting.

    This is very annoying, because on 10.9.1 and below, my laptop would be on WiFi and connected instantly upon waking my laptop up. I've repaired permissions and ran Onyx, to no avail.

    Is anyone else experiencing this problem?

    Late 2012 13.3" rMBP with the same issue over here ever since the update. Incredibly annoying.

    No problem here with MBA 2012. It reconnects pretty much instantly (I'm using my MBA with a 2007 AirPort Extreme Base Station if that makes any difference).

    I had no issues with reconnecting until I installed the 10.9.2 update a few days ago. I've a 2013 Macbook Pro which came with Mavericks.

    Now it spends (what seems like) ages trying to reconnect and then it reconnects to the 2.4GHz network instead of the 5 GHz one. Clicking the icon shows that it can only see that network (usually there's at least 8 wifi networks visible around me). A while later (after another sleep or if I manually turn off/on the wifi) it's back on my 5 GHz network and the list shows all the others in my apartment block, as usual.

    I assume it's a driver issue or maybe some kind of power-manageemnt issue introduced by 10.9.2. Prior to this update it would reconnect virtually instantly and always back to the 5 GHz network.

    Glad I'm not the only one. It seems like a 10.9.2-specific bug, though it's a bit perplexing if it's varied across models.

    I strongly encourage you to submit bug reports at bugreport.apple.com; it's free, and the more reports that are sent about this issue, the more likely it'll be fixed by 10.9.3, or maybe even earlier in a supplemental update!

    Anyone with a desktop Mac (iMac/Mini/Pro) experiencing this? How about other MBP's (non/Retina) and MBA's? I want to know if this is more model-specific, or more sporadic.

    Can't - says I have to be an apple developer in order to log a bug.

    I'm seeing the same problem on my Late 2011 15" MBP after upgrading to 10.9.2.

    Mine is fine after sleeping but on when its off and I turn it on sometimes it will not connect. I need to goto network diagnostics. And before I can get all the way though it I get the message "network changes detected" and then it connects.

    I've never tried to "out wait it" to see if it would connect on its own. I will next time though...

    Sign up for an Apple developer account, which is free, then from there, you should have access to bugreport.apple.com?

    Bugreport is better. More precise and gets quicker attention.

    Also noticed this. Probably a 10 second delay before wifi works again.

    Yup. Late 2013 13" rMBP, used the Combo Update, WiFi now takes longer to reconnect.

    Did any of you try doing a SMC and/or PRAM reset? Did this clear the issue up?

    Tried SMC and NVRAM reset. No improvement.

    Waking from sleep when connected to a power supply is fine. A bit slower than before the 10.9.2 update but nothing major. On battery it takes around 30 seconds.

    Allright. I've posted a bug report at bugreport.apple.com - let's see what happens. I provided them a link to this thread so they can see others are experiencing the issue; if you can, and have access (requires a free Developer account), please file this bug, too! The more, the better chance it has to be fixed!

    Really? I have mine plugged in most of the day. When I open the lid it still takes 10-12 seconds to wake up.

    ? only 10.9.2 ?

    Its always been an issue after sleep, unless the "delay" has increased.

    in actual fact, since 10.9.2 i find its not instant to wake up either.. there's about 10 secs or so (granted part of that would probably be due that Hard dive must spin up first), but nether-the-less, still a noticeable delay. I do have an SSD, i may try with that on my MBP and see if its any quicker.

    for me, it's been almost alternate updates; on 10.9.1, my mbp connected immediately after waking. before that, it was slow. it's been back & forth for a couple of years.

    would LOVE to figure this one out....

    Prior to 10.9.2 reconnecting was stupid fast - open the lid, boom, connected.

    In 10.9.2, most of the time it's reasonably quick, but sometimes it take 5-10 seconds - which is a long time when you're used to practically instant!

    Nothing interesting in the console logs.

    I agree. It wasn't a problem at all in Mountain Lion and 10.9.0/1; this purely began with 10.9.2 - and sometimes it's quick, sometimes 5-15 seconds. It's sporadic behavior.

    I've done a sysdiagnose and attached it to my bugreport to Apple; I encourage y'all to do the same if you use bugreport.apple.com :)

    So far, a second SMC reset (initially I did a SMC then NVRAM reset - so maybe just doing it the other way around would help?) and I'm reconnecting immediately, to my top preferred wifi network. Just like it was prior to 10.9.2.

    I'll report back in a few days if it's still working fine, or quicker if it screws up again :)

    Edit: It's screwed again.

    Let me chime in the chorus, as I also have this WiFi reconnect problem with my 2011 MBPro.

    I've written to Apple Feedback a couple times about this issue; it wasn't fixed in 10.9.2.
