    Default Kitkat upgrade today - can't turn on wifi anymore!

    Go the kitkat upgrade today for my s3 from USC. Now I can't turn on wifi. It's grayed out - and won't turn on. Anyone have any advice? Tried powering off, airplane mode on / off. Just doesn't turn on anymore!

    Have you tried booting into Recovery mode and clearing the system cache?
    What about a Factory Reset?

    I tried wiping the cache and it still is messed up , just upgraded about an hour ago and as soon as it started up the wifi couldnt turn on .. I really hope a patch is made for this really soon!

    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 got the update last night and am seeing the exact same thing. The on/off switch for wi-fi is grayed out and can not be turned on.

    I'll be calling US Cellular tonight when I get home!

    I just called customer support and they suggested doing a factory reset. They said they need as many examples as possible so they can take this back to Samsung.

    I'll be trying it today, hopefully it works out.

    Won't that delete all your apps and data?

    I got the same response. You just have to back up whatever you care about, contacts, photos etc. They'll walk you through the backup but you may need a computer and usb connection if your sync to google isn't working.

    The guy I talked to said that the factory reset has fixed the problem for everyone he talked to this morning, and that the reset was the only fix they knew of so far.

    Good luck everyone!

    Did you do a factory reset, or did it just not malfunction when you upgraded?

    Have you actually tried the reset yet, and did it work?

    Upgraded on wifi, stayed on the whole time. No malfunction, no issues whatsoever. US Cell did replace my phone about a month ago, as it was "not performing to their standards" (they contacted me to replace phone) - was in a serial number range or something...

    Same! The reset worked for me too. Seems like most of my apps and data, call and text logs are getting restored through my samsung acct as well.

    Same with me. How many does it take before they fix it? Factory Reset it not a fix. It's no wonder people root their phones when the channel upgrades do this.

    The factory reset worked for me, and luckily everything was backed up. Good luck to everyone else who is having this issue.

    I got the push early friday (june 27th 2014). I figured as in past never know when or why they arrive but I did not think anything negative would come of it. Since I ran the update phone has been inconsistent and gmail has had sync errors. Quite upset and cant believe of all things the gmail is now not working.

    If you have ANY issues following an OTA update there are two things you should do before deciding that the update is flawed:
    1. Boot into Recovery mode and clear the system cache
    2. If that doesn't make any difference, perform a Factory Reset (obviously this will wipe all of your data so be sure you have made a backup of anything you consider important - Kies is a great tool for this)

    My wife and I were both having wifi issues on our recently updated Galaxy Note 2's. It wasnt greyed out but would rather say we were connected but not be able to go actually use the internet. After talking to verizon they ended up sending her a new phone that works. Now today my phone started doing the same thing as hers had did. I was messing around in the router settings and accidentally turned off WPS(which should have probably been off anyways) and to my surprise it started working and is still working. Could just be a coincidence, but my accident totally worked so I thought I would share. Try to get to your router settings and turn off WPS... good luck!

    EDIT: It did work for about a day and then went out again.For some reason each time I turn WPS on or off it starts working. Not ideal but its working again for now...

    Try "Wifi Fixer" from Google Play or http://www.appsapk.com/wifi-fixer-app/
    I've tried flashing over and over, all available patches: same issue, until i got Wifi Fixer.
    Works now like a charm
