How-to Fix OS X 10.9 Mavericks – Wi-Fi Issues

Many users are experiencing issues with their Wi-Fi connection on their devices after upgrading to the OS X Mavericks. The issue ranges from not being able to connect to the network after waking up the device from sleep mode to intermittently being disconnecting from the network to not even being able to connect. I have gathered the most common workarounds/fixes for this issue.

Wi-Fi Issues Workarounds/Fixes

PRAM Reset

1. Power off computer.

2. Turn on the computer and immediately hold Option, Command, ‘R’, and ‘P’ keys simultaneously until you hear the start up sound for the second time. The second start up sound indicates that the parameter random access memory (PRAM) has been reset.

  1. For me, I found that simply deleting the whole “Location” preset in the System Preferences>Network tab and starting from scratch instantly solved the problem.

  2. Deleting the system configuration folder worked for me. I tried the PRAM and SMC tips first and they didn’t help. So relieved to finally be done with that silly exclamation point.

  3. Deleting config folder and uninstalling an old mcafee driver I thought I had removed long before mavericks update did it for me. My money is on the config folder though.

  4. You have kept a grown man from crying. I can’t tell you the number of manipulations that I have tried and as a non-initiated person, I have spent MANY hours just getting to you.
    Praised be your erudition and generosity in sharing it. William

  5. Thank you very much!

    WOW, for now, the last 10 minutes i’ve had a steady connection!!

  6. Hard to articulate my thanks to you. No words, really.

    I worked through all steps, up to and including turning off bluetooth, and that did the trick.

  7. Thank you so much!!! I did everything except the keychain disable, and the PRAM reset. I did the SMC reset last, and once I did, my internet worked. I spent over three hours with my company IT guy, with no results. 10 mins following your steps worked. Wow — you’re awesome.

  8. Setting the Order for service worked for me. I also changed the “Wake for network access” first but it didn’t change anything. So I’m not certain if in combination they are working or if the Order for Service was simply the answer.

    Thank you!!

  9. GENIUS!!!! what an incredible service you provided us…..it’s working, i still cannot believe it :) )

  10. THANK YOU!!!! This has been one of the singularly most frustrating Mac experiences I have had and NO ONE has been able to fix it until now. Many, many thanks for your generous posting and ingenuity!
