Q: iOS 6.0.1 WiFi Still Greyed Out

I had the same problem and I took it to an Apple store and thankfully they gave me a new phone.  No more problems with the greyed out Wi-Fi.

Well, i had the same problem too. But, i went to Apple Store, and they told me have WATER, yes.. WATER on the "wifi thing".  I don't know why, because I never even dropped my phone on the floor, so.. no water there. I am SURE!

They said the warranty don't support personal damage, so I need to pay $199 to replace my phone. It's UNFAIR, I am ****** with Apple right now. My phone don't have 2 months still.

do you pay something for replace your phone?

Nothing at all.  Thankfully I still had it under warranty.

Ah, The old "water in the iPhone trick." I'm pretty sure this is an illegal way for Apple to void most of its warranties. The moisture indicator is INSIDE the phone--how can they tell whether it got wet while in my possession, or during shipping to an apple store, or while in inventory, or whether some poor Chinese indentured servant spilled his daily ration of water during assembly?

And it's not even that they think the water damaged the phone, btw. It's just that it's in the terms of use that if that little indicator turns pink, it voids the warranty. I guarantee that strip turns pink the first time you cough or sneeze on the phone. The freaking earth is mostly water! I'm mostly water! It really shows the evil genius of apple.

It's almost as bad as saying, "That wifi issue is a hardware issue, but only on the kind of hardware that has iOS 6."  In some places, you big dummies, that's also called a software issue.

I dont know why this works but it does...

1/ goto safari settings and delete history,cookies etc

2/ goto settings,general,reset,reset networksettings

The wifi problem should be resolved

Hope that helps

After a few months of updating to iOS 6.0.1 my 4S wifi went blank (greyed out), it had no option for turning on Wifi.  My phone had turned into a snicker bar.  I did the following...after I accidentally let the phone died due to 0% battery.

1. Restored with iTunes

2. Holding both buttons at the same time (Top & Home Button)

3. Let the phone died completely by draining its battery

4. Repeat step 2 = it works again!!!!

Not for me.. ty

The Safari cookies solution worked...for about half an hour.  Now back to a grayed out wifi toggle, and clearing the cookies doesn't work when tried a second time.

All of these solutions have the potential to work temporarily, but the problem always recurs, and the solutions seem to only work once, then never again.

I am sorry but it shows its defo software

Do it all again inc reset network settings. It did same for me but ws too late to reply last night. Its now 12hours plus and still going

Same thing is happened to me last week. Wifi option is greyed out, hopefully Apple are planning to release iOS 6.1 this week Beta 4 for 6.1 expires on Monday.

Had the same problem for 2 days, tried all the tricks around apart from the heating and cooling and nothing worked. Went to apple store they took the phone left me for 5 minutes and came back saying that it is a fault that happens quite often after iOS upgrade and simply got me a new phone with 90 days warranty saying if the same thing happens again don't book an appointment just come straight to the store and we will replace it again. Also they recommended not to upgrade the iOS in the near coming future.

So I suggest paying them a visit before fiddling around with your phone; nothing to loose.

Thanks Apple.

Well I just updated to 6.1 and still the same issue... Nothing has changed here. Move along..
