    It happened with many of us. Simple and effective solution is to downgrade the upgrade/update to previous one.
    Step 1 > Factory Reset
    Step 2 > Download a firmware from sammobile.com
    Step 3 > Flash it with latest Odin.

    Reboot.

    Wi-fi must be working!!

    Enjoy

    "I have the same problem. Wifi is greyed out, and won't stay on or register any sources. If you hit "Advanaced" options, the "On" switch turns green in the background, but it doesn't change anything, Tried rebooting, removing battery, removing and replacing sim card, etc. Nothing has worked yet. Without wifi, my phone is useless. Hope someone figures something out."

    I contacted Verizon and had it out with them. They tried everything I told them that I did and they are sending me a new handset. If that one has a bricked WiFi then I'm just going to ask for a different handset. I am not happy about it. I love the Note 3 but I gotta have WiFi.

    Wiped Cache
    Factory Reset
    Safe Mode Boot
    Pulled the SIM card, reinsert
    Pulled SD card (in case it's corrupting)

    I registered just to say thank you and encourage others to try this. On the surface it seems like a coincident, but it somehow works. I had tried everything suggested here to no avail until I tried your suggestion.

    I tried everything mencioned here and nothing worked. I lost all my texts and contacts. I could only backup photos and other media. Wifi still won't turn on, so I can't restore anything. My phone is probably as good as dead
    Can anyone help?

    I did the following after nothing worked:

    1. turn off the phone
    2. Boot into Recovery mode
    3. perform a Factory Reset (backup before reset!!)
    4. clear the system cache

    So far so good. But it still didn't work until I did the following:

    I started the phone and skipped all questions of the wizard, in other words I didn't switch on wifi, no google account, no samsung account, I switched off any internet connection so that the phone couldnt connect to any server or whatever. Then I switched off "Software-Update" in Settings - Device info - Software update.

    After that I started WiFi and up to now it works. After connecting via Wifi I started to register with google and downloaded all apps.

    Hope that helps!

    I think its not necessary to flash a different firmware as many people wrote that the wifi problem was still there.

    I tried the following and so far it works:

    You need access to the file system of your phone via Total Commander!

    If your phone is not rooted follow steps 2. - 5. If it is rooted start the Total Commander App.


    1. Download Total Commander App from the App Store to your phone
    2. Download Odin to your PC and install it
    3. Download CF-Auto-root file for your phone, in my case s4-lte-gt-i9505
    4. Make sure that you have the right file for your phone!
    5. Root your phone now using Odin v3.07 or higher and CF-Auto-Root-jflte-jfltexx-gti9505.tar.md5 (in my case this one is for Samsung S4 GT I9505) - how to root you can find on inspiredgeek dot com
    6. Start Total Commander App
    7. open the file "system" (can be that this file is found in the file "root")
    8. open "built.prop" with Total Commander Editor
    9. search for "ro.securestorage.support = true" and change the value to "false"
    10. Safe file
    11. Reboot your phone

    Wifi should work again.

    i have found the solution for this ....

    i have the same issue with my samsung note 3 neo... about a while the wifi cant turn on... even after resetting it keeps coming up in a while... but i have discover the best solution without resetting my phone...

    solution:
    turn off your phone..
    dissamble the battery...
    wait for 3 min...
    put the battery again...
    at this moment, hold the power button together with the up volume button.... your phone now will turn on and go into safe mood ...
    at this moment , the wifi problem should have fixed....
    lasttly, restart your phone as usual , and its all good...

    this solution works for me, hope it will work for you too ...
