JUST GOT THE FIX!!! PERIOD!

turn off your iphone 4s

take clean towel and package your device

put this device to freezer in 5 minutes

after that, turn on device

wifi will be open

Wow - I cannot believe it but turning my phone all the way off and then putting it in the freezer for 5 minutes actually worked!! Thank you so much everyone for all of the help!

Any one have this "problem" since upgrading to io6?

Wifi works fine at home, but when you are at a location that has a "guest" wifi with one of those "agree to our terms" prompts when you first connect has been an irritating issue for me. Since I am frequently at locations that have this type of arrangement for visitors I use them quite often.

Before with 5.1.1 I could connect to one of those sites once and as long as I didn't go out of range I would stay "live" the whole time I was there. But now with io6, it seems every time the phone becomes inactive I have to agree the "terms" page when I try to use the wifi again.

It seems as though they have made it so the wifi actually powers off the instant the phone is inactive for a few minutes which at any of those guest wifi's makes it seem like you are connecting for the first time again. I suppose on my home wireless it is no problem because it reconnects quickly and it seems rather seemless.

This is on a iPhone4 by the way...

Settings>wifi>(select blue arrow for more options)

Scroll to the bottom of the page and select HTTP Proxy from OFF to AUTO.

If this doesn't work, try settings>general>reset>reset network settings and try the previous step again.

How can I turn on my WIFI if the button is GREYED out? It is disabled! There is no way to toggle it on or off. I've tried everything, resets and al, including restoring to it's factory setting. NOTHING WORKED. 😟

thats my issue to but i fix it..with a simple crazy idea..try to put yout device or freezer in 3-5 mins to cool the hardware or if u want just turnoff your device and let it cooldown at a moment...its work for me..this one is a crazy stupid way to fix it but it work fine on me..

Apple just replaced my 'grayed out' wifi, 4s, manufactured unblocked phone today. Went in, showed them, they fiddled for about 10 minutes and then handed me a replacement said that is a problem they are not capable of dealing with. Had them put ios6 on right there in the store.

They offered no explanation as to why this has occured and made it sound like the problem is rare. Seriously, they said they've seen a 'couple' with the wifi grayed out.

Couple, really...

You have got to be kidding me! Stick it in the freezer?? GTFOH! But it works!!!!! If I hadn't seen it myself, I would sware I was being juked. Whoever thought this up is a genious. Thanks very much!

Hey Guys,

Tried the Fix but its a NO GO,nothing changed.

I am on a carrier in Trinidad & Tobago and the same issue with the the wifi option greyed out.

It was available before I upgraded to IOS6

Any solutions out there?

Take it back to Apple and get a replacement. That's what I did.

I have talked to Apple and they are just replacing any device's who have the Wi-Fi greyed out issue if it hasn't already been resolved by standard troubleshooting.

I can't believe it. I have had the wifi off and "grayed out" for over a month. I stuck it in the freezer for 5 mins and its working again. Thank you. Un-F'in-beleivable.

Where did you find the option to turn the WiFi to auto? I can't locate it.

Because therre isn't an option for this.

They are referring to the HTTP Proxy at the bottom of the wifi network you are connecting to in Settings > WiFi.

Thanks for the reply Chris,

But my WiFi issue is that I can't get to the page where it actually scans for networks. When I open Settings, WiFi is turned off. When I select it to try to turn it on, it takes me to a greyest out page with an off/on slider. But it won't allow me to slide the switch to "on." So, I can't get to the area you mentioned where I could reset to auto.

But I appreciate your reply. Thank you.
