OS X Yosemite (dark mode, Hamza Sood 001)

After upgrading their Macs to yesterday’s OS X Yosemite 10.10.1 software update, some users continue to experience a range of intermittent Wi-Fi issues that have been plaguing Apple’s latest desktop operating system since its release, according to user feedback over at Apple’s Support Communities containing more than a thousand posts.

Issues vary on a case-by-case basis and include dropped or unreliable wireless connections, slow data transfer speeds, connections randomly dropping every few minutes or so, inability to connect to a Wi-Fi network after waking from sleep and more.

It’s unclear what percentage of those that have upgraded to 10.10.1 continue experiencing Wi-Fi issues. Apple has not officially commented on the matter yet.

Some posters advise removing previously saved networks in System Preferences > Network > Advanced to improve Wi-Fi performance, which I did and nevertheless continued to experience problems re-connecting to my home Wi-Fi after waking from sleep.

Are you plagued by Wi-Fi issues in Yosemite and if so, has 10.10.1 solved at least some of your Wi-Fi woes? Share your experience with readers down in the comments.

If I were you, I’d make sure to update the firmware on my home wireless router. This can be usually done by logging into your router in a web browser. You’d typically log into an internal webpage at, but check your router’s documentation. Then go to the update section or some such in order to download the latest device firmware.

Another workaround, albeit temporary, would be to try disabling Bluetooth. And if you own an AirPort wireless appliance, use the AirPort Utility to change the 5GHz frequency band or switch to a 2GHz network because nearby 5GHz routers often contribute to network congestion.

For what it’s worth, release notes accompanying the 311-megabyte OS X 10.10.1 update mention fixes for unspecified Wi-Fi issues as well as improved reliability for connecting to Microsoft Exchange corporate email servers.

If you haven’t installed 10.10.1 yet, it’s available through the Updates tab of the Mac App Store (the “App Store…” item under the Mac menu).

    There is still some problem connecting to the WAP2-Enterprise encrypted WiFi hotspots of my university, but much better now. It used to automatically disconnect around every 30 seconds, now it would only happen once an hour or less. WP2-Personal is much better, almost no issue.

    • Steve R.

      Same, my university’s wifi kept on disconnecting intermittently and now seems to be working normally as of the 10.10.1 update yesterday.

    • It’s so bad for me if I’m near another PC I tend to pinch an ethernet cord from the back of it and connect it to a thunderbolt-to-ethernet adaptor. Haven’t tried it since the update but hopefully things have changed for the better…

    What about 8.1.1?

  • Heitor Castro 

    OS X 10.10.1 solved Wi-Fi problems on my MacBook Air, which was dropping everytime and I have to reconnect it to my Wi-Fi to work again.

  • Shawn

    10.10.1 and 8.1.1 solved my WiFi issues on both my iOS and OS X devices. Bonus is it seemed to have fixed Safari from crashing webpages

  • Carlos Gomes

    WiFi was fixed, but the laggy and broken volume feedback thingies are still there. I can also not connect my MBA to my TV using an HDMI cable.

    I’m all in for improvements, but having to deal with silly and annoying bugs (Hello WiFi) with every single yearly release sucks.

  • Frogmen

    I was having problems with the wifi connections before and after upgrading to 10.10.1. Low speed and disconnections are driving me crazy. I bought the MACBOOK PRO coming from windows and I think i’m going back to windows next time.

  • jp2002

    Happy with 10.9.5!

  • aw81

    I’d love to try this update but my mbp won’t boot into OS X at all now, recovery doesn’t work either.
    Add the problems my iPhone has with 8.1 and I’m wishing I had stayed on Mavericks and ios7 now…

  • Courtney Macfarlane

    I’ve been having a few freezing problems with my macbook pro since I’ve updated 🙁 It’s getting really annoying!

  • Guy1717

    I had Magic mouse lag and disconnecting, streaming to apple tv stutters and with the 10.10.1 these problems persist, so i downgraded to Mavericks with Time Machine and now everything works like a charm. I’m staying with Mavericks.

  • Guy1717

    I forgot to mention Yosemite draining my 8 gb ram on MBpro late 2013 and lots of beachballs. Even after rebooting and not opening apps my Ram went down to 1 Gb or so

  • Donny Arikanami

    I have no problem with wifi on my MBP late 2011 since the release of 10.10, mac appstore seems to be running ok as well, but battery performance down a bit compare to 10.9.5, kinda strange on 10.10 after full charge 100%, unplugging the mac safe, suddenly battery drop to 98% didn’t happened on 10.9.5. now after 10.10.1 same problem. other than that, yosemite rocks….

  • What’s with WiFi these days? I keep reading about updates breaking it on Windows, iOS, Mac OS X, Android, and what not…glad I don’t have such fundamental problem with my devices.

  • Paymon John Vafa

    Hey is anyone having problems with Bluetooth on Yosemiti? I am still having issues even after the update… Its so frustrating I may even revert back to Mavericks.

  • Michael Fink

    Wi-Fi issues still on 10.10.1 MacBook Air 13″ (mid 2012). Wi-Fi drops after awaking from sleep in Enterprise. We have never had issues with any of our Mac’s and connectivity on our domain, from 10.6.x Lion to 10.9.x Mavericks. Once we upgraded to 10.10 Yosemite this problem started. Issues as well with my personal Apple Airport Time capsule and Wi-Fi drops – switched over to 2.5 Ghz and I have not experienced any drops on this device. Apple should be embarrassed and really needs to find the solution to this! Even Microsoft would have fixed this by now!

  • I still have plenty of intermittent problems — after waking from sleep, in the middle of calls, it’s always looking for networks. Big mistake upgrading to Yosemite. It took them 9 months to fix similar issues in Mavericks. Once it was perfect, I enjoyed it for awhile, then went to Yosemite like a dummy.
    AppleCare is useless — they have no idea what to do about it.

  • iViperzLTD

    10.10.1 for me, seems to have solved my wifi connectivity issue at my university, but despite being connected the wifi icon keeps indicating it’s looking for a network, which is strange since I’m browsing happily. Not a major concern, just an annoyance

    • Doughboi

      Same here. This was a replacement – my first MBP didn’t do this, however mine is constantly look for networks… In Mavericks, I could go into properties unclick/click a radio button and the behavior would stop, but not in Yosemite..at least not yet.
