ios 6.1.2 wifi is work ??? in iPhone 4s

Works for me.

The update is not intended to address WiFi problems, though, only a bug with Microsoft Exchange servers.

For grayed out Wi-Fi, take a look at this Apple doc -> iOS: Wi-Fi or Bluetooth settings grayed out or dim

If those 5 steps don't let you turn Wi-Fi on, the iPhone will need service.

Me wifi on/off was also greyed out. but I reset my iphone 4s twice and then it came back to normal.

I just updated my iphone 4 and 4s and now I am not able to connect with Wifi network 😟

Also updated this morning to iOS 6.1.2 on IPhone 4S and can't connect any Wifi network at all. Wifi button is GREYED OUT!!! It't now on his way to apple service center for repair.

Dear Apple.

I was really happy with my iphone4s, IOS 6.0, great product amazing quality and posibilities BUT.......

I updated from IOS 6.0 to 6.1.1. and the WIFI nightmare started.

I waited for a new update to fix the WIFI problems and I updated my iphone 4s from 6.1.1. to 6.1.2. in order to solve these problems related with WIFI connections.

But IOS 6.1.2. is even worst:

- WIFI is not working at all. So I cannot download apps greater than 50MB.

- Battery life is shorter than ever.

- 3G goes in and out every minute.

- When you operate the iphone4s you can realize that is hotter than before.

These problems are unnaceptable and inconsistent with a high quality standard product.

You can read a lot of blogs, I am not the only one.

Please give us a solution as soon as possible.

Best Regards

Call Apple support or visit an Apple Store. If the normal software solutions don't help, they will replace your iPhone. Posting here will not help, since we're all just fellow users here.

I have the same problem, since updating to OS6.1.2 my wifi has greyed, 4 apps continue to crash and the battery last less and then iphone heats....... sincerly with the price we pay a Iphone and the quality standards Apple goes around exploiting this is not acceptable.... i will have patience and wait for the next update hoping it will repair the bugs but if i have to change my phone due to these problems and apple does not accept thier fault i will pass to Samsung or Stonex
