Upgraded to iOS6 now I can't use wifi on iPhone 4S

I have tried the numerous fixes above but none have worked.

My issue is that under Settings/Wi-Fi I am not able to turn Wi-Fi on. The icon has grayed out and wont let me do anything in this screen.

I would be grateful for any advice on this.

Thanks.

thanks mate! aha

I am having the same problem!! Has Apple solved this??? Any ideas how to solve this??😠

I tried everything mentioned here and still nothing. I went to Apple store in Shanghai and they won't replace or do anything about the phone 'cause I got mine in Australia. 😠 According to them, iphone in china and outside of china are different. Apple, tell me, what do I do now?😕

Could someone PLEASE tell me, HOW DO I TURN MY WIFI button ON? IT is completely grayed out... I can't even turn it on...

I've done the RESET yada yada yada... But, even with that- it still hasn't allowed me to TURN my WIFI button ON......please HELP!!!!!

it's no use to discuss and expect from apple to solve this ******* problem, for one week i have been searching for problem and was excepting from apple to give a solution.nither apple assure that it is a hardware or software problem.guess apple is going to loose brand name,

till the time apple can't declare to replace wifi because people are having same problem right after they update their software to 6.0.1, what am i supposed to do as i need wifi on my phone for work. i invested on apple due to reliable, durable but now i guess apple's days has gone as a grama phone but wrost than that, at least grama phone has still holding it's quality but apple ..... have no word to say ****

All greyed out - Me too - whats next?

If the IPhone no longer does what it says it does - its time for a new phone a new direction that works
