iOS 6 WiFi option is GREYED OUT (unrelated to iOS 6 WiFi connectivity issues)

I upgraded the first time via OTA (wifi) and second time via USB. Both didn't work.

ok cool thanks for update..removes that as an issue.

I heard somewhere else on the forums that this disabled issue was a h/w issue caused by liquid spill or dropping the phone, i had to laugh...

The first call the girl had me do all the reset network setting and full restore and to call back if that didn't work. So I called back and they sent me up the chain to the senior tech and telling everything to her I sent her a screen shot and she said its defiantly an apple problem and they are working on it.

yeah thanks for update . issue has to be on Apple's end no other option really.

I have heard everything from trying turn off/on Siri, Celluar Data, locations services, delete the multi tasks, turn off HTTP proxy, forget the WIFI network (which you can't even get to), restore from backup, restore just IOS, and the list goes on.. to even a wifi expiration on teh chip set... ALL wont work. Now's it's funny that it's caused by moisture. The only moisture is my sweat dropping off my forehead trying to get this fixed all day!

Maybe's "SameSungs" attempt to tell me I'm an idiot for not buying there phone!

If wifi is greyed out in settings screen the hardware has died. There is not any troubleshooting that will fix it. Automatically needs repair. Usually was broken by someone dropping it or getting it wet.

yeah well the mobile market is very competitive these days so the only good will for me not to change to another vendor is to exchange mine for an iPhone 5 with working IOS6... 😀

other posters advertise that when they downgrade their phones back to IOS 5.1.1

the wifi works again, how can this be a H/W problem???

I downgraded mine and it worked. Upgraded a SECOND time and it didn't. Now tell me it's a hardware issue and why you say that?

Ive tried both over the air and itunes and both havent worked. my phone is 16gb 4s barely 4 months old. definalty glitch in software

The bigger problem Apple has to solve is with Wifi disabled, you can't upgrade or apply the fix via OTA. It will have to be done with wired. That is not good as alot of people dont have a computer available at times but went to upgrade.

After reading all of the posts here. I believe mine to be a hardware issue. My "No Wi-fi" issue started a few weeks ago with ios 5.1.1. Phone is 6 months old. I don't have Apple care but I do have an extended plan from Best Buy. So after a few trips to the store and several of their reps looking at the phone and going "...huh??" they told me to wait for ios 6, that is supposed to fix the issue. So after waiting "patiently" I upgraded a couple of days ago. Still the same issues. The Wifi is greyed out and can't turn on. Back to Best Buy tomorrow.

There is a simple test to see if this is true for any given device.

Go to Settings > About. Look for the WiFi MAC address.

iPhone that have been dropped or water damaged do occasionally destroy WiFi chipsets, which results in the same symptom (grey toggle on the WiFi Settings screen). If your chipset is broken / loose / damaged, Settings > About will NOT show a MAC address for your WiFi adapter as iOS is not able to find a working chipset. If this is the case you definately have a HARDWARE issue and the only solution is repair or replacement.

If you DO see a MAC address for the WiFi adapter, but you are still getting the grey WiFi toggle issue, then your WiFi is disabled as a SOFTWARE BUG in the iOS 6 update.

In the second instance the issue SHOULD be fixed by Apple in a future iOS update, though the fact they've known about this bug since June and haven't bothered fixing it yet shows you how low a priority this is so don't hold your breath for iOS 6.0.1 to come out tomorrow. In the mean time the only other option is to have Apple replace your phone with one that does not exhibit this issue.

I have solved my wifi greyed issue. Please see below steps.

1. Deleted the iOS 6 ipsw file from my system. C:\Users\user\AppData\Roaming\Apple Computer\iTunes\iPhone Software Updates

2. I clicked 'Restore', a fresh new download.

3. After the process, configure all the settings like apple id, icloud, blah blah.

4. Closed all unning application in the background.

5. Turn the iphone off, wait for 2 minutes, then turn on.

Hope it will work for you all.
