OS X Yosemite WiFi bug, drop issues during review

By Daniel Chubb - Oct 20, 2014

Apple’s OS X Yosemite WiFi bug would fall under teething problems, but these network drop issues can be especially frustrating thanks to almost everything we do needing access to the Internet. We previously heard that Yosemite WiFi keeps dropping, but it really hit home during our review on a MacBook Air Mid 2013 13-inch model.

This particular MacBook has a 1.3 GHz Intel Core i5 and 4GB of 1600 MHz DDR3 RAM, although it’s unclear if the OS X Yosemite WiFi disconnecting has anything to do with a particular model running version 10.10. The WiFi keeps dropping every few minutes and even when we are really close to our office router.


During our review, we played with different options to see if these problems could be solved. While there wasn’t any clear pattern, we did notice turning off Bluetooth seemed to fix the OS X Yosemite WiFi bug, or at least it didn’t drop for a while and resulted in less issues.


Are you experiencing a problem with OS X Yosemite WiFi disconnecting and if so, what hardware are you running? We have reached out to Apple for comment after seeing these issues during our first impressions, although we expect Apple not to comment until the first 10.10 update releases. You can read about slow Internet problems and an issue with AirPlay within earlier articles.

    1. Turn off power saving modes
    2. Make sure that your “Service Order” (in Network Preferences) is set to wfi FIRST
    3. Also, you may need to remove Thunderbolt Bridge on top of these (this is what finally worked for me)
    4. Turn off your “wake for network access”

  • jptagman


    1. System Preferences
    2. Energy Saver
    tab over to Power Adapter
    and make sure “Wake for Wi-Fi Network access” is checked!!!!!!!!!!!

    basically with out it checked, the WIFI will not have a steady stream connection to the wireless router,
    it will be more super up and super down, like lag spikes…….

    Latest since yesterday see below: New in! Skype 7.2.412 seems to have done the trick, Yosemite 10.10.1 powered Macs working OK. Skype 5.8.519 for iOS 8.1.1 also now not dropping audio. Thanks Skype for quick response.

  • JARP

    We have a late 2013 20 inch iMac and late 2012 MBP 13 inch both running Yosemite 10.10.1 with Skype 7.1.665, both drop the Skype audio in less than a minute. iMac is connected via ethernet, MBP via 5 Ghz WiFi. Also iPod Touch 4th generation obviously on 2.4 Ghz and iPhone 5s both drop on audio except the iPhone is OK on 3G. The Skype prog on the iPod touch has not been upgraded for a while, but we have a new TalkTalk dual band Super Router with Simply Broadband and fibre medium. Is this the problem, maybe the router settings need changing. Any Help would be sooo appreciated!

  • jbaywatch

    Update did not resolve the wifi issues for me. I have an 2013 imac in the kitchen and a mid 2012 macbook pro. both are able to connect to the AP, but there is little to no WAN connectivity. Neither of my ubuntu 12.10 or windows 8.1 desktops have any problems connecting to or using the same Access Point. The router is a top of the line ASUS RT-AC87R router.

  • Dori Settles

    I did NOT download Y yet, but do have the security patch that came out late Sept/early Oct (so I’m at 10.9.5), it auto installed on me one night. Ever since the wifi is hit or miss. I suspect THAT patch is part of Yosemite… πŸ™ I always try to wait a month or longer before installing. I haven’t even updated IOS on the phones yet! If anyone has a solution, I’m all ears. I tried a couple I found with no luck. I would need to do a file-based backup to revert to the previous Mavericks, which sounds time consumingly painful. Although at this rate, it might be better…

  • Prof. Peabody

    I’m thinking it has to do with Bluetooth, because it didn’t happen on Yosemite with my Mac Pro (older Bluetooth hardware), but the minute I bought a new iMac, it can’t stay connected. At least, it can’t stay connected at 5GHz, it will drop every few minutes unless I connect at the old speed. This with the router less than 10 feet from my desk.

  • Tony

    I am encountering the same issue. I just bought a Macbook Pro Retina 13.3′ and it has the same issues with disconnecting / dropping my wifi connection randomly.. Any idea when a fix is scheduled to be released ?

  • ukdoodlebug

    Too late. I’ve upgraded and I’m having the same problems. I have a 2014 MacBook Air:

    yosemite is a major fail when it comes to using internet. Please dont upgrade to yosemite until this bug is acknowledged by Apple and fixed in time! At the moment yosemite for me is a constant source of annoyance.

  • Chinny

    My mid 2012 Mac air just got the update yesterday to Yosemite- now the wifi drops like crazy!! 4 times in 7 mins. As for iPad 3, after the update, safari takes forever to get to the site and the screen freezes all the time! I have to move the search page up and down and that works sometimes to unfreeze it so i can click the link. No problem as yet with my bluetooth connection (just now trying it). Apple needs to publicly acknowledge this is an issue and fix it! my mac is very unreliable!

  • genesis667

    Same thing, mouse and keyboard keep disconnecting, more the keyboard then the mouse and it takes a good 5 minutes each time to get it to reconnect, not good when I have customers waiting for their information…

  • Denis

    Same issue… extended:
    I have 3 networks (2 x 2Gb, 1 x 5Gb); before the upgrade, only 2Gb nets were reachable from my MacBook Air (i7, 4G, 2011 release); now, I see all of them but only one 2Gb net runs almost stable;
    But I have other issues I never got before: MS Word, Excel and PowerPoints are crashing several times a day; same for Google Chrome and Safari. And obviously they never do that before;
    last point: a file that I modified on this machine where not readable on another MacBook Air (same configuration); for this one I have only one test, but it never occurs before.

    Regarding iOS8 on an iPad 3: after 8.0 upgrade, I was roughly not able to use any browsers anymore: reaction time was so slow that the interface was not usable anymore, with counter commands crossing each others; after the 8.1 patch, it has been improved A LITTLE BIT ! Still not very easy to use it and sometimes interface freezes…

    So: Apple has been striking a huge shot this time… in it’s foot πŸ™

    • Slack

      The words that you are using. Sense cannot be made of them.

      • Denis

        Well… it was late and I must admit some words are fuzzy…. But basically:
        On Yosemite
        Wifi is unstable
        MS Suite is crashing
        Chrome and Safari are freezing

        On iOS8.1
        Chrome and Safari are very slow and sometimes crashing or freezing.

        Is it clearer ? πŸ™‚

    • DJSM

      I’m assuming you mean 2.4GHz and 5GHz (not 2Gb and 5Gb)???

  • Nancy

    Just installed Yosemite and now I cannot connect to the internet via my laptop. MacBook Pro 15in 2011? I’ve tried rebooting computer and router, fiddling with settings. Turned off Bluetooth. no dice. The icon displays bars as if I’m connected. So frustrating!!! Other devices connecting to Internet without any problem.

    • Andrew Guo

      Having same problems here. Except I can connect. Only thing is, when I open some apps that use wifi like Skype (which I deleted), the internet is still on full bars, but cannot connect to wifi. I’m thinking of downloading Mavericks but I don’t know if it will fix it. Currently just waiting till Christmas to see if they have an update for a bug fix, if not, then I’m going to Redownload Mavericks.

  • Anton Dubinsky

    Yup, same problem. Only rebooting seems to fix it.

  • Alimacg

    I am having the same problem:( The moment Yosemite was installed, wifi disappeared. I cannot join routers but CAN connect via my phone???

    • Jonathan Michael Luna

      Exact same issue.. My computer will not recognize the wifi port pre-installed. after updating. Were you able to get this issue resolved?

  • wg seattle

    My mac mini never lost wifi connection, was extremely stable until the yosemite upgrade, now it can’t stay connected more than a few minutes at most. I have tried all the posted ideas, multiple times in some cases, most of the time during which I can’t keep a wifi connection going long enough to try half of them seamlessly. I am tired of this. I count on my mac being a good machine and expect it to work better than this. The store suggested it’s our network issues, but that’s so much bs I can’t begin to tell you how discontented I am with the apple store techs for even suggesting that my new mac mini, that worked just fine til the yosemite upgrade and which there are pages and volumes of this happening to everybody else, that they would try to blame our setup on the issue, insinuating that we perhaps need to learn more about networking. Both myself and my partner are networking people, have had mac and pc products for a long time, we build networks for people and apple has decided that we don’t know enough to figure out what might be happening. Apple needs to address this wifi issue. And soon.. myself and others use our macs for more than just playing games on them.

  • jpodcaster

    Yes, I’m getting this issue on my late 2013 13″ MacBook Air (1.7 i7) since upgrading to Yosemite. Doesn’t do it as frequently as some are reporting here – more like every hour or so. A re-boot temporarily solves the issue until the next disconnection. I have turned off bluetooth but use it for handoff (which I’m loving!).

  • Dav17

    I’ve had my Mac Pro for some years and it’s been great. But now that I’ve installed Yosemite It won’t connect to my router and I’m fed up of being nagged to join up to a temporary BT network, grrrr. It won’t detect the router, even when it’s right next to it, but detects the modem booster I have attached to it. However, it won’t accept the password even though it is the right one. On the few occasions that it does it doesn’t last long before it begins fluctuating and drops. This is rediculous, people need the Internet for everything and to release an os in this state is just careless. I’m a writer and I need the Internet to make submissions, you are affecting my ability to work! Sort this out and fast! And if you’re wondering, I’ve written this with an iPad.

  • Kristine Pierce

    Frustrated! Woke up this morning to my Macbook Air 11″ 2013 model gasping for wifi connection. πŸ™ upgraded to os x yosemite about a week ago…it was working smoothly the first week, then it started acting up πŸ™

  • Tim

    I loaded yosemite on my 2011 Mac Mini but not on my 2010 macbook pro. The mini cannot maintain a wifii connection and the keyboard responds terribly. No problem with the macbook pro with wifii or internet access.

  • Andrew

    Yes!! I’m having trouble with my MacBoo Pro 15″ Retina. I think it’s a 2013 model.

  • Annoyed

    I’m having the same problems with my 2014 Macbook Pro retina 15″. It’s been especially clear when doing Skype calls for my work, which is driving my insane.

    • fredrik

      I have the same problem. Wifi connection loses if using Skype

  • dj2819

    Me and my sister have identical mid 2012 macbook pros updated to yosemite. Only hers drops signal every few minutes. Mine is running perfectly normal. She needs to keep clicking the network name to connect again.

  • Jason Young

    Yea, this is getting rediculous!!!!! Dropping on me every 3-5 minutes non-stop for over 4 days now!

  • vc

    I also had my wifi dropping out every 5 minutes and it was driving me bonkers. Then I power cycled my wireless router and, touch wood, my connection hasn’t dropped since. Might be worth a try…

  • Matt

    It’s a funny thing. I thought maybe there was a physical barrier blocking my Wifi signal, but it looks to be a software issue.

    I have a consistent internet connection – I can download, stream, and upload content – but the wifi signal keeps fluctuating indicating that it’s actively searching for a connection. Then randomly it drops out, resets, or turns off.

    This is a bit of a mess. I’m running a Late 2013 MBP. Considering Apple removed a hard-wired internet port from this machine, I think I might even upgrade this ‘mess’ to ‘disaster’.

  • jv araneta

    Bluetooth not functioning. Internets is slower vs the older OS.

  • Π‘Π΅Ρ€Π³Π΅ΠΉ

    New trouble with wifi on 10.10 – No Hardware Installed

  • Harry Hornblower

    Same issue with my MacBook Pro 13 retina (early 2013). iOS 8 killed my phones bluetooth as well, brand new car without hands free now. Apple have been dropping the ball lately, really giving me the poos.

  • I have a MacBook Air and a MacBook Pro which I have upgraded to Yosemite.
    The MacBook Air connects fine to my home network which uses a TimeCapsule as the access point. It connects there fine and remains stable.
    I’m a HS Principal and took my MacBook Air to a meeting at our administration building this morning. It would connect to the network and then drop off within 2 minutes. I tried removing the wireless network and rejoining it with the same result.
    I took my MacBook Air to our technology support building where it would connect and remain stable with no problems.
    I then brought it back to my HS Office, where it connects and then drops within 2 minutes.
    I then tried to connect it to the AirPort in my office and it connects fine and remains stable.

    the issue seems to be related to the network configuration, as the three locations at work where I tried to connect are all a part of the same WAN, but different LANs. It connects to one and not the 2 others I’ve tried. I haven’t tried other locations in our district yet, but anticipate similar problems.

    Interestingly, my MacBook Pro connects in all locations without dropping. This would make me think it could be an OS issue with my MacBook Air and specific network configurations, not just an overall OS issue.

  • Masselink

    My problem was solved after the following steps

    – Turn wifi off
    – Remove the stored wifi networks
    – Disable the wifi interface
    – Remove the wifi interface
    – reboot
    – Add the wifi interface again
    – reboot
    – Connect to the network

    (I also reset the keychain to default, but i think that didn’t affect my installation)

    • Rik

      Thanks! So far it helps to keep wifi connection stable. It’s weird that menu bar says “Wi-Fi: Not configured” while in System Preferences I’m connected….

      • Bob

        Just go back into the network setting and uncheck and recheck the “Show wifi status in menu bar” box and it should go back to normal.

  • Michael Dunham

    Since upgrading to Yosemite, I have been fighting with this problem of dropping wifi. There are literally 100’s of messages on Apple support detailing various attempts to work around the issue. Nothing really works. This is clearly an OS problem and for some reason it didn’t rise up to prominence until the full release. It was noticed by some people in Beta, but with release – it has become a huge issue. I cannot use the internet without losing connection every few minutes and it is random. Sometimes it will stay connected for several minutes – sometimes only seconds. It is very frustrating and needs to be addressed quickly.

  • Rik

    I already reported this issue during Beta testing! Turning bluetooth off does not help for me πŸ™ Also sometimes Finder can not make connection with TimeCapsule.

    • Rik

      It seems to help to close connection to TimeCapsule, in my case…….

      • Rik

        Connecting phone for USB tethering causes a system crash almost immediately πŸ™

  • Naqib

    I installed Yosemite a few days ago..I noticed the internet to be slow and generally it seems to lag in general especially when I’m doing a whole load of stuff that was usually not a problem when using Mavericks..After reading some forums and noticing some people complained that their wifi connection was definitely somehow influenced by the bluetooth being on..I tried it for myself by not using my mac supermouse and the trackpad and wireless keyboard..Viola like magic..somehow wifi became stable and faster..Sad thing is it means if I want reliable internet I can’t use my Thunderbolt display with the Wireless keyboard,mouse and Trackpad..Hmmm I hope this bug gets fixed real soon…it’s definitely slowing me down ..

  • Abhishek

    Very annoying problem. This is killing productivity. Apple is completely ignoring this issue – or so it seems.
    Even some of the “semi-official” commenters on Apple support forums seem to be in a state of denial.
    Journalists of-course cannot write about this, as then it is good-bye to invites to the next Apple bash.

  • MacBook Pro (Retina, 13-inch, Late 2013). Drops wifi every few minutes. A complete PITA. I’m a little surprised something so critical (WIFI internet Access) could be so wrong.

  • MsAngry

    I have a MacBook Pro, mid 2012, 15-inch model. My wifi doesn’t even last for more than 30 seconds. I’ve tried everything under the sun but it was to no avail. I just updated to OS X Yosemite 3 hours ago, and before that my wifi was working fine. This is a serious problem. WTF? I hope Apple gets this fixed ASAP(!!!!!) because I really need wifi for school.

  • ST

    iMac (27-inch, Late 2012), 3.2 GHz Intel Core i5, 8 GB 1600 MHz DDR3

    Since I upgraded, I’ve been having the same issues. I tried at least 5 of the recommendations I found in various forums and none of them worked. Now there is a different issue that is worth investigating. I can keep wi-fi if it is on a Public network, but as soon as I try our WPA, it drops every 15 to 30 seconds. I’m not even fortunate enough to get the 2 or 3 minutes others do.

  • Abhinav

    same problem with my macbook pro mid 2010 model 13 inch. the wifi is slow and keeps dropping every few minutes. I then have to turn off wifi on the mac and reconnect to the network. I also tried connecting to the internet directly with wire and it works fine.
    Yosemite surely has a problem with wifi. Wonder what kind of testing apple does before releasing this type of software. This is such a basic thing.

  • SarahDiczok

    Same problem – drops wifi every few minutes on a Late 2011 13 inch MacBook Pro. Very irritating

  • HL

    I have a different problem – Since upgrading to Yosemite a very slow response to everything I try doing – opening an email, scrolling down on a document, opening a day in the calender – first there is no response, then a colored turning wheel shows up, and the finally it works. When I try again to do the exact same thing it works OK, but when going to a different document, and then back to the first one – all over again with the colored wheel… Very annoying. Any ideas what to do?

  • Christian Ryan

    I’m running a clean Mac OS X Yosemite install on a 2012 MacBook Pro Retina 15″ model. I use a Magic Trackpad and a Wireless Keyboard as input devices, both of which are connected to the computer via Bluetooth. So naturally, Bluetooth and WiFi are both enabled almost all the time. After the clean install of mac OS X.10, I’ve been experiencing the following bug: at random times, both Bluetooth devices behave very sluggishly and keep disconnecting from the laptop. This issue seems to be fixed whenever I turn off WiFi: Both devices work fine after that. And when I turn WiFi back on, the same issue presents itself. After a reboot, Both devices and WiFi work for a while, simultaneously that is. And after a random amount of time, it seems, the bug returns.

    This is really annoying, as I use the laptop in closed Clamshell mode, connected to an external monitor. So when this problem occurse, I have to disconnect everything from the laptop and open it up so I can reboot it. It’s really tome consuming!

  • Andes Cruz

    I’m on an iMac 2009-2010, I boot up, everything is good, and then within 15 min to an hour, the internet and email lose connection. (alternate connections like ftp, and other downloads are fine and working) Does not come back until I reboot, and then the same thing happens. (Also have not been able to use Safari since upgrade, it crashes.)

  • Macromagnon

    Macbook Pro non-retina mid 2012. Does not connect to 5 GHz 802.11n WiFi on Time Capsule immediately after Yosemite was installed. Can still connect to 2.4 GHz WiFi on Bell Canada 2-Wire router, but with extremely slow connection/transmission there. But iOS 8 devices and Mavericks Mac Pro still work perfectly well on both networks. It does NOT help to switch bluetooth on or off.

  • AR

    MacBook Pro mid-2012 2.6 GHz 15″

  • elsoufiano

    Macbook Air 13″ Mid 2012. Internet works slow and than drops after a few minutes. Very frustrating. Apple please fix that!

  • G’Zilla

    Yes and I’m not to happy about it! Tried everything too! I’ve got a MBP, retina, 15, 16 GB 1600 MHz DDR3, 2.6 GHz Intel Core i7, Mid 2012 model…(It dropped 2 times while typing this).

    I do hope Apple comes up with a fix and soon and understands there is even a problem. Everything worked fine for me before and now it don’t. Little help here!! I notice the Wi-Fi: Looking for Networks never goes away even when connected…so there seems to be a lack of communication here. I’m sure this will be a simple fix.

  • Bappel

    Early 2013 iMac

    Got the same problem. Disconnecting BT is out of question due to both keyboard and pad is in use of that.

  • Pili777

    Mid 2012 Retina Mac Book Pro 15”. Same problem. Seem to be better if I have no devices connecting over Bluetooth (even if Bluetooth is on). But fairly random, sometime I get a few 100bits/s sometimes the network works OK. Everything was fine before Yosemite. My connection works fine if I connect via Ethernet, or using my wife’s Mavericks’ based MB air.

  • Travis

    Same thing for me. Spent about three hours on phone with Apple care yesterday. Tried everything under the sun to fix it. Even when booting computer up outside of the OS, it still dropped. They think it has to do with wireless card. I’m not buying it. Too convenient that it began right after I upgraded to yosemite. All prior versions worked just fine. I plan on seeing if it holds a connection somewhere other than my regular home network. If not, it is either going to the apple store or I will just downgrade the OS.

  • Matto

    Yep, my 2012 non Retina Macbook Pro has problems with wifi dropping out without reason. Had already tried turning off bluetooth with little or no improvement. Still happens. Also, I use airplay a lot, and it is now dropping out heaps, with it sometimes being because of wifi dropout. Airplay itself is slow across the wifi network.

  • Robin

    Nightmare, apple should really fix this issue ASAP, and they should try not to make any mistakes like this.

  • Jess

    it’s really strange, one minute everything works great and then my wi-fi keeps dropping every minute for a while. There is a big problem and it needs fixing ASAP.

  • James

    Keeps dropping on my macbook air as well, nightmare…I will try turning off bluetooth.
