iPhone Wifi won't turn on after iOS 6 update

[giper54]

I have an iPhone 4S on AT&T. I updated to iOS 6 last night and after the update I can't get my wifi to turn on. When I go to wifi in settings it is greyed out. I know there is a wifi bug is this it. If not has anyone else experienced it and fixed it so wifi. Can turn on again

I've been having the same exact problem and have been unable to find a way to fix it even after doing a network reset and a full system reset. Seems to be a bug with the new iOS, hopefully there will be a fix soon.

Same problem here. There is a discussion all over the apple forums with no real fix. Some are even going as far as returning their phones back to apple.

Same issue here on my iPhone 4s. Tried restoring in DFU mode and no dice, still not able to turn Wireless back ON in settings. I also tried resetting carrier network settings but that didn't help, any clue what else I can do?

I restored the iPhone 4s to factory settings and still no wireless, it is greyed out and won't let me turn on.

Thanks,
Shane

my mom just got an iPhone 5 about 3 months ago and this issue showed up last week. She took it into the apple store and they tried a full clean install but with no luck, they replaced it no questions asked. Apparently they've been seeing a number of these.
